NFSD 7.1 Release Notes Benjamin Coddington contributed filehandle signing to defend against filehandle-guessing attacks. The server now appends a SipHash-2-4 MAC to each filehandle when the new "sign_fh" export option is enabled. NFSD then verifies filehandles received from clients against the expected MAC; mismatches return NFS error STALE. Chuck Lever converted the entire NLMv4 server-side XDR layer from hand-written C to xdrgen-generated code, spanning roughly thirty patches. XDR functions are generally boilerplate code and are easy to get wrong. The goals of this conversion are improved memory safety, lower maintenance burden, and groundwork for eventual Rust code generation for these functions. Dai Ngo improved pNFS block/SCSI layout robustness with two related changes. SCSI persistent reservation fencing is now tracked per client and per device via an xarray, to avoid both redundant preempt operations on devices already fenced and a potential NFSD deadlock when all nfsd threads are waiting for a layout return. The remaining patches deliver scalability and infrastructure improvements. Sincere thanks to all contributors, reviewers, testers, and bug reporters who participated in the v7.1 NFSD development cycle.
Staging driver changes for 7.1-rc1 Here is the "big" set of staging driver changes for 7.1-rc1. Nothing major in here at all, just lots of little cleanups for the staging drivers, driven by new developers getting their feet wet in kernel development. "Largest" thing in here is the change of some of the octeon variable types into proper kernel ones. Full details are in the shortlog. All of these have been in linux-next for a while with no reported issues. Signed-off-by: Greg Kroah-Hartman <[email protected]>
USB / Thunderbolt changes for 7.1-rc1
Here is the big set of USB and Thunderbolt changes for 7.1-rc1.
Lots of little things in here, nothing major, just constant
improvements, updates, and new features. Highlights are:
- new USB power supply driver support (will cause merge conflicts in
drivers/power/supply/Makefile, but it's a simple fix) These changes
did touch outside of drivers/usb/ but got acks from the relevant
mantainers for them.
- dts file updates and conversions
- string function conversions into "safer" ones
- new device quirks
- xhci driver updates
- usb gadget driver minor fixes
- typec driver additions and updates
- small number of thunderbolt driver changes
- dwc3 driver updates and additions of new hardware support
- other minor driver updates
All of these have been in the linux-next tree for a while with no
reported issues

TTY/Serial changes for 7.1-rc1 Here is the set of tty and serial driver changes for 7.1-rc1. Not much here this cycle, biggest thing is the removal of an old driver that never got any actual hardware support (esp32), and the second try to moving the tty ports to their own workqueues (first try was in 7.0-rc1 but was reverted due to problems.) Otherwise it's just a small set of driver updates and some vt modifier key enhancements. All have been in linux-next for a while with no reported issues.

Hi Wolfram,
here is the second part of the i2c-host pull request for v7.1.
Just three patches, all tested in i2c-host-next for quite some
time. The pxa change is the second patch of a two-patch series.
The first one [*] went in as a fix in -rc5.
Note that this pull request is in i2c/i2c-host-2 instead of the
usual i2c/i2c-host. I created that branch for part 2 and last
rebased it on top of v7.0.
Thank you and have a great Sunday,
Andi
[*] 78a6ee14f8b9 ("i2c: pxa: defer reset on Armada 3700 when
recovery is used")
i2c-host for v7.1, part 2
- cx92755: convert I2C bindings to DT schema
- mediatek: add optional bus power management during transfers
- pxa: handle early bus busy condition
Here is the i3c subsystem pull request for 7.1. This time, we get support for Intel Nova Lake-H and a way to enforce rescanning the bus. Small issues have been fixed in many drivers and the error code hanlding for CCC commands have been reworked. I3C for 7.1 Subsystem: - add sysfs option to rescan bus via entdaa - fix error code handling for send_ccc_cmd Drivers: - mipi-i3c-hci-pci: Intel Nova Lake-H I3C support
here are the pin control changes for the v7.1 kernel cycle. There is a little bit of everything this time. Some core improvements on semantic checks. Some bunch of new drivers. Cleanup series. But overall pretty straight-forward. Some SCMI changes probably came in before through an immutable branched pulled by the GPIO subsystem. Details in the signed tag as always. Yours, Linus Walleij Pin control changes for the v7.1 kernel cycle: Core changes: - Perform basic checks on pin config properties so as not to allow directly contradictory settings such as setting a pin to more than one bias or drive mode. - Handle input-threshold-voltage-microvolt property. - Introduce pinctrl_gpio_get_config() handling in the core for SCMI GPIO using pin control. New drivers: - GPIO-by-pin control driver (also apperaing in the GPIO pull request) fulfilling a promise on a comment from Grant Likely many years ago: "can't GPIO just be a front-end for pin control?" it turns out it can, if and only if you design something new from scratch, such as SCMI. - Broadcom BCM7038 as a pinctrl-single delegate. - Mobileye EyeQ6Lplus OLB pin controller. - Qualcomm Eliza and Hawi families TLMM pin controllers. - Qualcomm SDM670 and Milos family LPASS LPI pin controllers. - Qualcomm IPQ5210 pin controller. - Realtek RTD1625 pin controller support. - Rockchip RV1103B pin controller support. - Texas Instruments AM62L as a pinctrl-single delegate. Improvements: - Set config implementation for the Spacemit K1 pin controller.
This is a followup pull which is mostly next material with some fixes. Alex pointed out I missed one of his AMD MRs from last week, so I added that, then Jani sent the pipe reordering stuff, otherwise it's just some minor i915 fixes and a dma-buf fix.

- Support flat layout for symfs. The --symfs option is to specify the
location of debugging symbol files. The default 'hierarchy' layout
would search the symbol file using the same path of the original file
under the symfs root. The new 'flat' layout would search only in the
root directory.
- Update 'simd' sort key for ARM SIMD flags to cover ASE/SME and more
predicate flags.
perf stat:
- Add --pmu-filter option to select specific PMUs. This would be
useful when you measure metrics from multiple instance of uncore PMUs
with similar names.

hwspinlock updates for v7.1 Remove the unused u8500 hardware spinlock driver, and clean out the hwspinlock_pdata struct as this was the last user of the struct.
rpmsg updates for v7.1 Mark "data" argument in rpmsg_send() const, and perculate to related drivers. Replace deprecated class_destroy() with class_unregister().
remoteproc updates for v7.1 Move requesting of IRQs in TI Keystone driver to probe time instead of remoteproc start, to allow better handling of errors. Introduce support for more than 10 entries in the Qualcomm minidump implementation. Add audio DSP remoteproc support for the Qualcomm Eliza platform. Add modem remoteproc support for the Qualcomm MDM9607, MSM8917, MSM8937, and MSM8940 platforms. Add list of Qualcomm QMI service ids to the QMI header file, in order to avoid sprinkling them across the various drivers using them. Migrate sysmon to use this constant. Fix several issues related to DeviceTree parsing and mailbox handling in the Xilinx R5F remote processor driver. Fix incorrect error checks in reserved memory handling and polish the code across i.MX and TI drivers.
There's a couple of conflicts now with your current tree. linux-next has the correct resolutions.

Bootconfig for v7.1: - bootconfig: Minor fixes for handling errors, which includes the following commits: . fix off-by-one in xbc_verify_tree() next node check . increment xbc_node_num after node init succeeds . validate child node index in xbc_verify_tree() - bootconfig: Code cleanups (mainly type/attribute changes), which includes the following commits. . clean up comment typos and bracing . drop redundant memset of xbc_nodes . replace linux/kernel.h with specific includes . narrow flag parameter type from uint32_t to uint16_t . constify xbc_calc_checksum() data parameter . fix signed comparison in xbc_node_get_data() . use size_t for strlen result in xbc_node_match_prefix() . use signed type for offset in xbc_init_node() . use size_t for key length tracking in xbc_verify_tree() . change xbc_node_index() return type to uint16_t bootconfig-v7.1
This is another larger set of changes from the soc tree after a rather
quiet 7.0 merge window. In total, we merged 88 branches with over
1000 non-merge changesets, in large parts due to massive devicetree
updates on both Qualcomm and NXP platforms. These include a total of
12 new SoCs, all of them part of an already supported chip family.

cycle, thanks. I'm seeing one conflict at this time, in fs/ocfs2/dir.c. The linux-next resolution is at https://lore.kernel.org/[email protected]. (Looks nasty, but a peek at 0b2600f81cefc shows what's going on). mm.git review status for linus..mm-nonmm-stable Total patches: 126 Reviews/patch: 0.92 Reviewed rate: 76% - The 2 patch series "pid: make sub-init creation retryable" from Oleg Nesterov increases the robustness of our creation of init in a new namespace. By clearing away some historical cruft which is no longer needed. Also some documentation fixups are provided. - The 2 patch series "selftests/fchmodat2: Error handling and general" from Mark Brown has a fixup and a cleanup for the fchmodat2() syscall selftest. - The 3 patch series "lib: polynomial: Move to math/ and clean up" from Andy Shevchenko does as advertised. - The 3 patch series "hung_task: Provide runtime reset interface for hung task detector" from Aaron Tomlin gives administrators the ability to zero out /proc/sys/kernel/hung_task_detect_count. - The 2 patch series "tools/getdelays: use the static UAPI headers from tools/include/uapi" from Thomas Wei=DFschuh teaches getdelays to use the in-kernel UAPI headers rather than the system-provided ones. - The 5 patch series "watchdog/hardlockup: Improvements to hardlockup" from Mayank Rungta provides several cleanups and fixups to the hardlockup detector code and its documentation. - The 2 patch series "lib/bch: fix undefined behavior from signed left-shifts" from Josh Law provides a couple of small/theoretical fixes in the bch code. - The 2 patch series "ocfs2/dlm: fix two bugs in dlm_match_regions()" from Junrui Luo does what is claims. - The 27 patch series "cleanup the RAID5 XOR library" from Christoph Hellwig is a quite far-reaching cleanup to this code. I can't do better than to quote Christoph: The XOR library used for the RAID5 parity is a bit of a mess right now. The main file sits in crypto/ despite not being cryptography and not using the crypto API, with the generic implementations sitting in include/asm-generic and the arch implementations sitting in an asm/ header in theory. The latter doesn't work for many cases, so architectures often build the code directly into the core kernel, or create another module for the architecture code. Change this to a single module in lib/ that also contains the architecture optimizations, similar to the library work Eric Biggers has done for the CRC and crypto libraries later. After that it changes to better calling conventions that allow for smarter architecture implementations (although none is contained here yet), and uses static_call to avoid indirection function call overhead. - The 2 patch series "lib/list_sort: Clean up list_sort() scheduling workarounds" from Kuan-Wei Chiu cleans up this library code by removing a hacky thing which was added for UBIFS, which UBIFS doesn't actually need. - The 5 patch series "Fix bugs in extract_iter_to_sg()" from Christian Ehrhardt fixes a few bugs in the scatterlist code, adds in-kernel tests for the now-fixed bugs and fixes a leak in the test itself. - The 3 patch series "kdump: Enable LUKS-encrypted dump target support in ARM64 and PowerPC" from Coiby Xu eenables support of the LUKS-encrypted device dump target on arm64 and powerpc. - The 4 patch series "ocfs2: consolidate extent list validation into block read callbacks" from Joseph Qi addresses ocfs2's validation of extent list fields - cleanup, simplification, robustness. (Kernel test robot loves mounting corrupted fs images!)
Arm:
- Add support for tracing in the standalone EL2 hypervisor code, which
should help both debugging and performance analysis. This uses the
new infrastructure for 'remote' trace buffers that can be exposed
by non-kernel entities such as firmware, and which came through the
tracing tree.
- Add support for GICv5 Per Processor Interrupts (PPIs), as the starting
point for supporting the new GIC architecture in KVM.
- Finally add support for pKVM protected guests, where pages are unmapped
from the host as they are faulted into the guest and can be shared back
from the guest using pKVM hypercalls. Protected guests are created
using a new machine type identifier. As the elusive guestmem has not
yet delivered on its promises, anonymous memory is also supported.
This is only a first step towards full isolation from the host; for
example, the CPU register state and DMA accesses are not yet isolated.
Because this does not really yet bring fully what it promises, it is
hidden behind CONFIG_ARM_PKVM_GUEST + 'kvm-arm.mode=protected', and
also triggers TAINT_USER when a VM is created. Caveat emptor.
- Rework the dreaded user_mem_abort() function to make it more
maintainable, reducing the amount of state being exposed to the
various helpers and rendering a substantial amount of state immutable.
- Expand the Stage-2 page table dumper to support NV shadow page tables
on a per-VM basis.
- Tidy up the pKVM PSCI proxy code to be slightly less hard to follow.
- Fix both SPE and TRBE in non-VHE configurations so that they do not
generate spurious, out of context table walks that ultimately lead
to very bad HW lockups.
- A small set of patches fixing the Stage-2 MMU freeing in error cases.
- Tighten-up accepted SMC immediate value to be only #0 for host
SMCCC calls.
- The usual cleanups and other selftest churn.
LoongArch:
- Use CSR_CRMD_PLV for kvm_arch_vcpu_in_kernel().
- Add DMSINTC irqchip in kernel support.
RISC-V:
- Fix steal time shared memory alignment checks
- Fix vector context allocation leak
- Fix array out-of-bounds in pmu_ctr_read() and pmu_fw_ctr_read_hi()
- Fix double-free of sdata in kvm_pmu_clear_snapshot_area()
- Fix integer overflow in kvm_pmu_validate_counter_mask()
- Fix shift-out-of-bounds in make_xfence_request()
- Fix lost write protection on huge pages during dirty logging
- Split huge pages during fault handling for dirty logging
- Skip CSR restore if VCPU is reloaded on the same core
- Implement kvm_arch_has_default_irqchip() for KVM selftests
- Factored-out ISA checks into separate sources
- Added hideleg to struct kvm_vcpu_config
- Factored-out VCPU config into separate sources
- Support configuration of per-VM HGATP mode from KVM user space
s390:
- Support for ESA (31-bit) guests inside nested hypervisors.
- Remove restriction on memslot alignment, which is not needed anymore with
the new gmap code.
- Fix LPSW/E to update the bear (which of course is the breaking event
address register).
x86:
- Shut up various UBSAN warnings on reading module parameter before they
were initialized.
- Don't zero-allocate page tables that are used for splitting hugepages in
the TDP MMU, as KVM is guaranteed to set all SPTEs in the page table and
thus write all bytes.
- As an optimization, bail early when trying to unsync 4KiB mappings if the
target gfn can just be mapped with a 2MiB hugepage.
x86 generic:
- Copy single-chunk MMIO write values into struct kvm_vcpu (more precisely
struct kvm_mmio_fragment) to fix use-after-free stack bugs where KVM
would dereference stack pointer after an exit to userspace.
- Clean up and comment the emulated MMIO code to try to make it easier to
maintain (not necessarily "easy", but "easier").
- Move VMXON+VMXOFF and EFER.SVME toggling out of KVM (not *all* of VMX
and SVM enabling) as it is needed for trusted I/O.
- Advertise support for AVX512 Bit Matrix Multiply (BMM) instructions
- Immediately fail the build if a required #define is missing in one of
KVM's headers that is included multiple times.
- Reject SET_GUEST_DEBUG with -EBUSY if there's an already injected
exception, mostly to prevent syzkaller from abusing the uAPI to
trigger WARNs, but also because it can help prevent userspace from
unintentionally crashing the VM.
- Exempt SMM from CPUID faulting on Intel, as per the spec.
- Misc hardening and cleanup changes.
x86 (AMD):
- Fix and optimize IRQ window inhibit handling for AVIC; make it per-vCPU
so that KVM doesn't prematurely re-enable AVIC if multiple
vCPUs have to-be-injected IRQs.
- Clean up and optimize the OSVW handling, avoiding a bug in which KVM would
overwrite state when enabling virtualization on multiple CPUs in parallel.
This should not be a problem because OSVW should usually be the same for
all CPUs.
- Drop a WARN in KVM_MEMORY_ENCRYPT_REG_REGION where KVM complains about a
"too large" size based purely on user input.
- Clean up and harden the pinning code for KVM_MEMORY_ENCRYPT_REG_REGION.
- Disallow synchronizing a VMSA of an already-launched/encrypted vCPU, as
doing so for an SNP guest will crash the host due to an RMP violation
page fault.
- Overhaul KVM's APIs for detecting SEV+ guests so that VM-scoped queries
are required to hold kvm->lock, and enforce it by lockdep. Fix various
bugs where sev_guest() was not ensured to be stable for the whole
duration of a function or ioctl.
- Convert a pile of kvm->lock SEV code to guard().
- Play nicer with userspace that does not enable KVM_CAP_EXCEPTION_PAYLOAD,
for which KVM needs to set CR2 and DR6 as a response to ioctls such as
KVM_GET_VCPU_EVENTS (even if the payload would end up in EXITINFO2
rather than CR2, for example). Only set CR2 and DR6 when consumption of
the payload is imminent, but on the other hand force delivery of the
payload in all paths where userspace retrieves CR2 or DR6.
- Use vcpu->arch.cr2 when updating vmcb12's CR2 on nested #VMEXIT instead
of vmcb02->save.cr2. The value is out of sync after a save/restore
or after a #PF is injected into L2.
- Fix a class of nSVM bugs where some fields written by the CPU are not
synchronized from vmcb02 to cached vmcb12 after VMRUN, and so are not
up-to-date when saved by KVM_GET_NESTED_STATE.
- Fix a class of bugs where the ordering between KVM_SET_NESTED_STATE and
KVM_SET_{S}REGS could cause vmcb02 to be incorrectly initialized after
save+restore.
- Add a variety of missing nSVM consistency checks.
- Fix several bugs where KVM failed to correctly update VMCB fields on
nested #VMEXIT.
- Fix several bugs where KVM failed to correctly synthesize #UD or #GP for
SVM-related instructions.
- Add support for save+restore of virtualized LBRs (on SVM).
- Refactor various helpers and macros to improve clarity and (hopefully)
make the code easier to maintain.
- Aggressively sanitize fields when copying from vmcb12, to guard against
unintentionally allowing L1 to utilize yet-to-be-defined features.
- Fix several bugs where KVM botched rAX legality checks when emulating SVM
instructions. There are remaining issues in that KVM doesn't handle size
prefix overrides for 64-bit guests.
- Fail emulation of VMRUN/VMLOAD/VMSAVE if mapping vmcb12 fails instead of
somewhat arbitrarily synthesizing #GP (i.e. don't double down on AMD's
architectural but sketchy behavior of generating #GP for "unsupported"
addresses).
- Cache all used vmcb12 fields to further harden against TOCTOU bugs.
x86 (Intel):
- Drop obsolete branch hint prefixes from the VMX instruction macros.
- Use ASM_INPUT_RM() in __vmcs_writel() to coerce clang into using a
register input when appropriate.
- Code cleanups.
guest_memfd:
- Don't mark guest_memfd folios as accessed, as guest_memfd doesn't support
reclaim, the memory is unevictable, and there is no storage to write
back to.
LoongArch selftests:
- Add KVM PMU test cases
s390 selftests:
- Enable more memory selftests.
x86 selftests:
- Add support for Hygon CPUs in KVM selftests.
- Fix a bug in the MSR test where it would get false failures on AMD/Hygon
CPUs with exactly one of RDPID or RDTSCP.
- Add an MADV_COLLAPSE testcase for guest_memfd as a regression test for a
bug where the kernel would attempt to collapse guest_memfd folios against
KVM's will.
Ever since Kari Argillander=E2=80=99s 2022 report regarding the "orphan" st=
ate
of the ntfs3 driver, I have spent the last 4 years working to provide
full write support and current trends(iomap, no buffer head, folio),
enhanced performance, stable maintenance, utility support including
fsck for NTFS in Linux. This new implementation is built upon the
clean foundation of the original read-only NTFS driver, adding:
- Full write support with delayed allocation.
- iomap and folio integration (removing buffer_head dependency).
- Better stability (passing 326 xfstests vs 273 for ntfs3).
- Come with a new suite of userspace utilities (ntfsprogs-plus).
The series has been reviewed and carries an Acked-by from Christoph Hellwig=
.
This series has been in linux-next for approximately two months. During
that time, additional fixes from Smatch static analysis and the patches
from other developers have been incorporated, including two build fixes
from Mark Brown(VMA descriptor rename and inode lookup u64 change) that
were picked up from linux-next.
Major changes:
- Write support:
Implemented full write support based on the classic read-only NTFS
driver. Added delayed allocation to improve write performance through
multi-cluster allocation and reduced fragmentation of the cluster
bitmap.
- iomap conversion:
Switched buffered IO (reads/writes), direct IO, file extent mapping,
readpages, and writepages to use iomap.
- Remove buffer_head:
Completely removed buffer_head usage by converting to folios.
As a result, the dependency on CONFIG_BUFFER_HEAD has been removed
from Kconfig.
- Stability improvements:
The new ntfs driver passes 326 xfstests, compared to 273 for ntfs3.
All tests passed by ntfs3 are a complete subset of the tests passed
by this implementation. Added support for fallocate, idmapped mounts,
permissions, and more.
- xfstests Results report:
Total tests run: 787
Passed : 326
Failed : 38
Skipped : 423
Failed tests breakdown:
- 34 tests require metadata journaling
- 4 other tests:
094: No unwritten extent concept in NTFS on-disk format
563: cgroup v2 aware writeback accounting not supported
631: RENAME_WHITEOUT support required
787: NFS delegation test
*** NOTE ***
This has a conflict with your current tree. I did a merge and pushed a
branch to my tree "merge/upstream". The file kernel/trace/trace.c has a
conflict and kernel/trace/trace.h has a mis-merge (adds a prototype
that was already added to the header by an upstream commit).
*** NOTE ***
tracing updates for v7.1:
- Fix printf format warning for bprintf
sunrpc uses a trace_printk() that triggers a printf warning during the
compile. Move the __printf() attribute around for when debugging is not
enabled the warning will go away.
- Remove redundant check for EVENT_FILE_FL_FREED in event_filter_write()
The FREED flag is checked in the call to event_file_file() and then
checked again right afterward, which is unneeded.
- Clean up event_file_file() and event_file_data() helpers
These helper functions played a different role in the past, but now with
eventfs, the READ_ONCE() isn't needed. Simplify the code a bit and also
add a warning to event_file_data() if the file or its data is not present.
- Remove updating file->private_data in tracing open
All access to the file private data is handled by the helper functions,
which do not use file->private_data. Stop updating it on open.
- Show ENUM names in function arguments via BTF in function tracing
When showing the function arguments when func-args option is set for
function tracing, if one of the arguments is found to be an enum, show the
name of the enum instead of its number.
- Add new trace_call__##name() API for tracepoints
Tracepoints are enabled via static_branch() blocks, where when not
enabled, there's only a nop that is in the code where the execution will
just skip over it. When tracing is enabled, the nop is converted to a
direct jump to the tracepoint code. Sometimes more calculations are
required to be performed to update the parameters of the tracepoint. In
this case, trace_##name##_enabled() is called which is a static_branch()
that gets enabled only when the tracepoint is enabled. This allows the
extra calculations to also be skipped by the nop:
if (trace_foo_enabled()) {
x = bar();
trace_foo(x);
}
Where the x=bar() is only performed when foo is enabled. The problem with
this approach is that there's now two static_branch() calls. One for
checking if the tracepoint is enabled, and then again to know if the
tracepoint should be called. The second one is redundant.
Introduce trace_call__foo() that will call the foo() tracepoint directly
without doing a static_branch():
if (trace_foo_enabled()) {
x = bar();
trace_call__foo();
}
- Update various locations to use the new trace_call__##name() API
- Move snapshot code out of trace.c
Cleaning up trace.c to not be a "dump all", move the snapshot code out of
it and into a new trace_snapshot.c file.
- Clean up some "%*.s" to "%*s"
- Allow boot kernel command line options to be called multiple times
Have options like:
ftrace_filter=foo ftrace_filter=bar ftrace_filter=zoo
Equal to:
ftrace_filter=foo,bar,zoo
- Fix ipi_raise event CPU field to be a CPU field
The ipi_raise target_cpus field is defined as a __bitmask(). There is now a
__cpumask() field definition. Update the field to use that.
- Have hist_field_name() use a snprintf() and not a series of strcat()
It's safer to use snprintf() that a series of strcat().
- Fix tracepoint regfunc balancing
A tracepoint can define a "reg" and "unreg" function that gets called
before the tracepoint is enabled, and after it is disabled respectively.
But on error, after the "reg" func is called and the tracepoint is not
enabled, the "unreg" function is not called to tear down what the "reg"
function performed.
- Fix output that shows what histograms are enabled
Event variables are displayed incorrectly in the histogram output.
Instead of "sched.sched_wakeup.$var", it is showing
"$sched.sched_wakeup.var" where the '$' is in the incorrect location.
- Some other simple cleanups.

- Enable AtomicOps only if we know the Root Port supports them (Gerd
Bayer)
- Don't enable AtomicOps for RCiEPs since none of them need Atomic Ops
and we can't tell whether the Root Complex would support them (Gerd
Bayer)
- Leave Precision Time Measurement disabled until a driver enables it to
avoid PCIe errors (Mika Westerberg)
- Make pci_set_vga_state() fail if bridge doesn't support VGA routing,

vga_get() callers including userspace via /dev/vga_arbiter (Simon
Richter)

Resource management:
- Prevent assigning space to unimplemented bridge windows; previously we
mistakenly assumed prefetchable window existed and assigned space and

resource_alignf callback so free space before the requested alignment
can be used (Ilpo Järvinen)

- Fix alignment calculation for resource size larger than align, e.g.,
bridge windows larger than the 1MB required alignment (Ilpo Järvinen)

Endpoint framework:
- Advertise dynamic inbound mapping support in pci-epf-test and update

avoid oops caused by doing the work after resources have been torn down
(Koichiro Den)
- Add a way to describe reserved subregions within BARs, e.g.,
platform-owned fixed register windows, and use it for the RK3588 BAR4
DMA ctrl window (Koichiro Den)

driver, and change some BAR_RESERVED annotations to BAR_DISABLED
(Niklas Cassel)
- Add NTB .get_dma_dev() callback for cases where DMA API requires a
different device, e.g., vNTB devices (Koichiro Den)
- Add reserved region types for MSI-X Table and PBA so Endpoint
controllers can them as describe hardware-owned regions in a
BAR_RESERVED BAR (Manikanta Maddireddy)

(Manikanta Maddireddy)
- Add Tegra194 and Tegra234 device table entries to pci_endpoint_test
(Manikanta Maddireddy)

please pull three futex selftests fixes for v7.1-rc1. Thx. --- =E2=80=94 Correct the version guard for the futex_numa_mpol test to requi= re libnuma 2.0.18 instead of 2.0.16, which is the version that actually introduced numa_set_mempolicy_home_node() used by the test =E2=80=94 Allow the futex_numa_mpol selftest to build and run on systems = without libnuma installed with affected test gracefully being skipped instead o= f failing to compile - Use the proper assertion macros so that individual sub-test failures ar= e correctly propagated and the test suite reports failure when something = goes wrong
tracefs updates for 7.1: - Simplify error handling with guards() Use guards() to simplify the handling of releasing locks in exit paths. - Use dentry name snapshots instead of allocation Instead of allocating a temp buffer to store the dentry name to use in mkdir() and rmdir() use take_dentry_name_snapshot(). - Fix default permissions not being applied at boot The default permissions for tracefs was 0700 to only allow root having access. But after a change to fix other mount options the update to permissions ignored the defined default and used the system default of 0755. This is a regression and is fixed. Changes since v1: https://lore.kernel.org/all/20260414075753.2a036358@robin/ - Removed unused 'ret' variable in eventfs_iterate() tracefs-v7.1-v2
please pull sound updates for v7.1-rc1 from: The topmost commit is e0da8a8cac74f4b9f577979d131f0d2b88a84487 sound updates for 7.1-rc1 Nothing too thrilling here, but we see lots of driver updates and bug fixes, including quirk additions and refactoring works, while there have been little changes in the core functionality. Here are some highlights: * Core: - Add validation for the control API put callback - Fixes in compress-offload API timestamp handling - Continued ASoC core API cleanups * ASoC: - Add support for bus keepers (for Apple devices in future) - Enhancements to the SDCA support, including retaskable jacks - Test improvements for Cirrus Logic drivers - Lots of fixes for the NXP, nVidia and Qualcomm - Support for AMD RPL DMIC, Cirrus Logic CS42L43 and CS47L47, nVidia machines with CPCAP and WM8962 * USB-audio: - Quirks for Huawei Headset, Focusrite Novation, MV-Silicon, Studio 1824, Arturia AF16Rig, Hotone Audio, Feaulle Rainbow, PreSonus AudioBox, Moondrop Ju Jiu, Scarlett 18i20, etc - Extended mixer volume quirk handling - UAF and other fixes for us144mkii, 6fire and caiaq drivers * HD-audio: - Add quirks or fixes for Acer, Lenovo, HP, ASUS machines - Fixes & cleanups of GPIO helper code * Misc: - Add suspend/resume support for multiple legacy ISA and Apple drivers - Further regression fixes for ctxfi driver
ring-buffer updates for 7.1:
- Add remote buffers for pKVM
pKVM has a hypervisor component that is used to protect the guest from the
host kernel. This hypervisor is a black box to the kernel as the kernel is
to user space. The remote buffers are used to have a memory mapping
between the hypervisor and the kernel where kernel may send commands to
enable tracing within the hypervisor. Then the kernel will read this
memory mapping just like user space can read the memory mapped ring buffer
of the kernel tracing system.
Since the hypervisor only has a single context, it doesn't need to worry
about races between normal context, interrupt context and NMIs like the
kernel does. The ring buffer it uses doesn't need to be as complex. The
remote buffers are a simple version of the ring buffer that works in a
single context. They are still per-CPU and use sub buffers. The data
layout is the same as the kernel's ring buffer to share the same parsing.
Currently, only ARM64 implements pKVM, but there's work to implement it
also in x86. The remote buffer code is separated out from the ARM
implementation so that it can be used in the future by x86.
The ARM64 updates for pKVM is in the ARM/KVM tree and it merged in the
remote buffers of this tree.
- Merge commit f35dbac69421 ("ring-buffer: Fix to update per-subbuf entries of persistent ring buffer")`
A fix was merged upstream that some new changes depended on. The upstream
commit was merged into the ring buffer branch to fulfil the dependency.
- Make the backup instance non reusable
The backup instance is a copy of the persistent ring buffer so that the
persistent ring buffer could start recording again without using the data
from the previous boot. The backup isn't for normal tracing. It is made
read-only, and after it is consumed, it is automatically removed.
- Have backup copy persistent instance before it starts recording
To allow the persistent ring buffer to start recording from the kernel
command line commands, move the copy of the backup instance to before the
the command line options start recording.
- Report header_page overwrite field as "char" and not "int'
The rust parser of the header_page file was triggering a warning when it
defined the overwrite variable as "int" but it was only a single byte in
size.
- Fix memory barriers for the trace_buffer CPU mask
When a CPU comes online, the bit is set to allow readers to know that the
CPU buffer is allocated. The bit is set after the allocation is done, and
a smp_wmb() is performed after the allocation and before the setting of
the bit. But instead of adding a smp_rmb() to all readers, since once a
buffer is created for a CPU it is not deleted if that CPU goes offline, so
this allocation is almost always done at boot up before any readers exist.
If for the unlikely case where a CPU comes online for the first time after
the system boot has finished, send an IPI to all CPUs to force the
smp_rmb() for each CPU.
- Show clock function being used in debugging ring buffer data
When the ring buffer checks are enabled and the ring buffer detects an
inconsistency in the times of the invents, print out the clock being used
when the error occurred. There was a very hard to hit bug that would
happen every so often and it ended up being only triggered when the jiffies
clock was being used. If the bug showed the clock being used, it would
have been much easier to find the problem (which was an internal function
was being traced which caused the clock accounting to go off).

This is the main drm pull request for 7.1-rc1. I found two conflicts when testing the merge: one in Rust core and one in Tyr, but both were trivial to solve. This has a fixed tree shared with driver-core tree in it, which Danilo will send later. Outside of drm: - mm: adding new statistics for GPU memory usage tracking and an EXPORT addition. - mm: mmu notifier addition for two-pass internal notifiers - math.h change to allow DIV_ROUND_CLOSEST to be used in uapi facing pieces= . -

Hi Arnd,
As you are worried about the last minute rebase done yesterday, here is
a new pull request without the rebase. It means it is based on tag
soc_fsl-7.0-2 that you merged into 7.0-rc5 some weeks ago.
Most commits have spent several weeks in linux-next, only the last one
spent only 10 days there, but it is not a major change and it is
originating from the maintainer of fsl-mc bus directly.
Commit a0fe29d20e78 ("soc: fsl: qe: panic on ioremap() failure in
qe_reset()") is also flagged as being commited 10 days ago, but this is
just because I droped the preceding commit.
Changes to fsl-mc bus are reviewed or acked by Ioana Ciornei.
Thanks
Christophe

Hi Linus,
Improvements and fixes kselftest, kselftest harness, frameworks
and individual tests:
-- cpu-hotplug: fix to check if cpu hotplug is supported to avoid
test failures when cpu hotplug isn't supported.
-- frace: fix to relevant comparisons and path checks in the helper so
it handles those patterns without spurious shell warnings.
-- runner.sh: add ktrap support
-- tracing: fix to make --logdir option work again
-- tracing: fix to check awk supports non POSIX strtonum()
-- mqueue: fix incorrectly named settings file to make sure the test
used the correct timeout value
-- kselftest:
- fix to treat xpass as successful result
- add ksft_reset_state()
-- kselftest_harness:
- validate kselftest exit codes are handled explicitly
- add detection of invalid mixing of kselftest and harness functionality
- add validation of intermixing of kselftest and harness functionality
-- run_kselftest.sh:
- remove unused $ROOT
- resolve BASE_DIR with pwd -P to avoid dependency on realpath
or readlink commands to generate a physical absolute path for
BASE_DIR
- allow choosing per-test log directory
- preserve subtarget failures in all/install
diff is attached.

please pull the x86/sev lineup for v7.1-rc1. Thx. --- - Change the SEV host code handling of when SNP gets enabled in order to = allow the machine to claim SNP-related resources only when SNP guests are rea= lly going to be launched. The user requests this by loading the ccp module = and thus it controls when SNP initialization is done So export an API which module code can call and do the necessary SNP se= tup only when really needed - Drop an unnecessary write-back and invalidate operation that was being performed too early, since the ccp driver already issues its own at the correct point in the initialization sequence =E2=80=94 Drop the hotplug callbacks for enabling SNP on newly onlined CP= Us, which were both architecturally unsound (the firmware rejects initialization = if any CPU lacks the required configuration) and buggy (the MFDM SYSCFG MSR bi= t was not being set) - Code refactoring and cleanups to accomplish the above
please pull the x86/misc lineup for v7.1-rc1. Thx. --- =E2=80=94 Reference the tip tree maintainer handbook directly from the re= levant MAINTAINERS file entries (covering timers, IRQ, locking, scheduling, pe= rf, x86, and others) so that contributors and tooling can know where to look =E2=80=94 Enable interrupt remapping in defconfig, which is an architectu= ral requirement for x2APIC to function correctly on bare metal. Without it= , x2APIC was effectively enabled but non-functional. =E2=80=94 Ensure that drivers which register custom restart handlers (suc= h as those needed for SoC-based x86 devices like Intel Lightning Mountain) are act= ually invoked during reboot, bringing x86 in line with how other architecture= s handle this. - Cleanups
please pull the x86/microcode lineup for v7.1-rc1. Thx. --- - The kernel carries a table of Intel CPUs family,model,stepping,...,etc tuples which say what is the latest microcode for that particular CPU. Some CPU variants differ only by the platform ID which determines what microcode needs to be loaded on them. Carve out the platform ID handling from the microcode loader and make it available in a more generic place so that the old microcode verification machinery can use it
please pull the x86 FRED lineup for v7.1-rc1. Thx. --- - We made the FRED support an opt-in initially out of fear of it breaking machines left and right in the case of a hw bug in the first generation of machines supporting it. Now that that the FRED code has seen a lot of hammering, flip the logic to be opt-out as is the usual case with new hw features
The only real thing of note here is printing the TDX module version. This is a little silly on its own, but the upcoming TDX module update code needs the same TDX module call. This shrinks that set a wee bit. There's also few minor macro cleanups and a tweak to the GetQuote ABI to make it easier for userspace to detect zero-length (failed) quotes. The GetQuote tweak collides with a fix that showed up around 7.0-rc5. Ingo resolved the conflict for the tip tree and I've appended it here in case it is useful to you. -- - Print TDX module version during boot - Make TDX attribute naming consistent
please pull the x86 resctrl lineup for v7.1-rc1. Btw, this is my first pull request text using AI. It is ok-ish but it was= too much bla so I had to shorten it into sanity. Some of the formulations are still "too much" but I'll be even more strict with the next ones. :-) Thx. --- =E2=80=94 Add return value descriptions to several internal functions, ad= dressing kernel-doc complaints =E2=80=94 Add the x86 maintainer mailing list to the resctrl section so t= hey are automatically included in patch submissions, and reference the applicab= le contribution rules document =E2=80=94 Allow users to apply a single Capacity Bitmask to all cache dom= ains at once using '*' as a shorthand, instead of having to specify each domain individually. This is particularly user-friendly on high core-count sys= tems with many cache clusters - When a user provides a non-existent domain ID while configuring cache allocation, ensure the failure reason is properly reported to the user rather than silently returning an error with a misleading "ok" status
This depends on tip/sched-core and cgroup/for-7.1 and should be pulled after both. sched_ext: Changes for v7.1 - Cgroup sub-scheduler groundwork. Multiple BPF schedulers can be attached to cgroups and the dispatch path is made hierarchical. This involves substantial restructuring of the core dispatch, bypass, watchdog, and dump paths to be per-scheduler, along with new infrastructure for scheduler ownership enforcement, lifecycle management, and cgroup subtree iteration. The enqueue path is not yet updated and will follow in a later cycle. - scx_bpf_dsq_reenq() generalized to support any DSQ including remote local DSQs and user DSQs. Built on top of this, SCX_ENQ_IMMED guarantees that tasks dispatched to local DSQs either run immediately or get reenqueued back through ops.enqueue(), giving schedulers tighter control over queueing latency. Also useful for opportunistic CPU sharing across sub-schedulers. - ops.dequeue() was only invoked when the core knew a task was in BPF data structures, missing scheduling property change events and skipping callbacks for non-local DSQ dispatches from ops.select_cpu(). Fixed to guarantee exactly one ops.dequeue() call when a task leaves BPF scheduler custody. - Kfunc access validation moved from runtime to BPF verifier time, removing runtime mask enforcement. - Idle SMT sibling prioritization in the idle CPU selection path. - Documentation, selftest, and tooling updates. Misc bug fixes and cleanups. - Merges from tip/sched-core, cgroup/for-7.1, and for-7.0-fixes to resolve dependencies and conflicts for the above changes.
please pull the RAS lineup for v7.1-rc1. Thx. --- - Add new AMD MCA bank names and types to the MCA code, preceded by a clean up of the relevant places to have them more developer-friendly (read: sort them alphanumerically and clean up comments) such that adding new banks is easy
workqueue: Changes for v7.1 - New default WQ_AFFN_CACHE_SHARD affinity scope subdivides LLCs into smaller shards to improve scalability on machines with many CPUs per LLC. - Misc: system_dfl_long_wq for long unbound works, devm_alloc_workqueue() for device-managed allocation, sysfs exposure for ordered workqueues and the EFI workqueue, removal of HK_TYPE_WQ from wq_unbound_cpumask, and various small fixes.
cgroup: Changes for v7.1 - cgroup_file_notify() locking converted from a global lock to per-cgroup_file spinlock with a lockless fast-path when no notification is needed. - Misc changes including exposing cgroup helpers for sched_ext and minor fixes.
Hi Linus,
Fixes kunit tool to
-- terminate kernel under test on SIGINT when it catches SIGINT
to make sure the TTY isn't messed up and terminate the running
kernel.
-- recommend --raw_output=all when KTAP header isn't found in the kernel
output, it's useful to re-run the test with --raw_output=all to find
out the reasons why the test didn't complete.
-- skip stty when stdin is not a tty to avoid writing noise to stderr.
-- show suites when user runs --list_suites option instead of entire
list of tests to make the output user friendly and concise.
diff is attached.
thanks,
-- Shuah

spi: Updates for v7.1 A busy release for SPI, almost all of it in a couple of larger fix and cleanup serieses for patterns that affected many drivers. We do have a couple of core API additions as well, relatively application specific but they enable some new use cases. - A packed command operation for spi-mem devices. - Improvements to the ancillary device support to enable some IIO use cases from Antoniu Miclaus. - Fixes for a registration ordering issue pattern caused by the handover between allocation and registration of controllers in concert with devm from Johan Hovold. - Improvements to handling of clock allocation from Pei Xiao. - Cleanups in the fsl-lpspi driver from Marc Kleine-Budde. - Support for Renesas RZ/G3E and RZ/G3L.
regulator: Updates for v7.1 This has been a very quiet update for the regulator API, the bulk of the diffstat is DT binding conversions and the most promient series in the changelog is Johan Hovold cleaning up some leaks of OF nodes. For some reason we have had several different people sending improvements to better describe the parent supplies for existing regulators, these look to be independent efforts. The only new hardware support is for some Motorola custom varints of cpcap.
regmap: Updates for v7.1 This has been quite a busy release for regmap, the user visible changes are quite minor but there's some quite good work on internal code improvements. - Cleanup helper for __free()ing regmap_fields. - Support non-devm I3C regmaps. - A bunch of cleanup work, mostly from Andy Shevchenko. - Fix for bootstrapping issues with hardware initialised regmaps, which was the main inspiration for some of the cleanups.
These align some the set_memory*() code better with the new page table APIs, especially using ptdescs as opposed to 'struct page' directly. -- - Convert x86 code to use generic "pagetable" APIs and ptdescs
The existing Linear Address Space Separation (LASS) support punted on support for common EFI and vsyscall configs. Complete the implementation by supporting EFI and vsyscall=xonly. The last few commits clean up CPUID use in the Intel "avs" sound driver and update the x86-cpuid-db file. -- - Complete LASS enabling: deal with vsyscall and EFI - Clean up CPUID usage in newer Intel audio driver
Here's the pull-request with the updates for MMC for v7.1. Details about the highlights are as usual found in the signed tag. Note that, this time I have picked up some changes to improve the mux subsystem and those are also part of this pull-request, as they are needed by mmc. Kind regards Ulf Hansson MMC core: - Add NXP vendor and IW61x device IDs for WiFi chips over SDIO - Add quirk for incorrect manufacturing date - Add support for manufacturing date beyond 2025 - Optimize support for secure erase/trim for some Kingston eMMCs - Remove support for the legacy "enable-sdio-wakeup" DT property - Use single block writes in the retry path MMC host: - dw_mmc: A great amount of cleanups/simplifications to improve the code - dw_mmc: Add clk_phase_map support - dw_mmc: Remove mshc DT alias support - dw_mmc-rockchip: Fix runtime PM support for internal phase - dw_mmc-rockchip: Add support for the RV1103B variant - loongson2: Add support for the Loongson-2K0300 SD/SDIO/eMMC controller - mtk-sd: Add support for the MT8189 variant - renesas_sdhi_core: Add support for selecting an optional mux - rtsx_pci_sdmmc: Simplify voltage switch handling - sdhci: Stop advertising the driver in dmesg - sdhci-esdhc-imx: Add 1-bit bus width support - sdhci-esdhc-imx: Add support for the NXP S32N79 variant - sdhci-msm: Add support for the IPQ5210 and IPQ9650 variants - sdhci-msm: Add support for wrapped keys - sdhci-msm: Enable ICE for CQE-capable controllers with non-CQE cards - sdhci-of-arasan: Add support for the Axiado AX3000 variant - sdhci-of-aspeed: Add support for the AST2700 variant - sdhci-of-bst: Add driver for the Black Sesame Technologies C1200 controller - sdhci-of-dwcmshc: Add support for the Canaan K230 variant - sdhci-of-dwcmshc: Add support for the HPE GSC variant - sdhci-of-dwcmshc: Prevent clock glitches to avoid malfunction - sdhci-of-k1: Add support for the K3 variant mux core/consumers: - core: Add helper functions for getting optional and selected mux-state - i2c-omap: Convert to devm_mux_state_get_optional_selected() - phy-renesas: Convert to devm_mux_state_get_optional_selected() - phy-can-transceiver: Convert to devm_mux_state_get_optional()

chrome-platform: Updates for v7.1
* Improvements
- Reduce transmission size by dropping unnecessary data in
cros_ec_lightbar.
- Convert chromeos_privacy_screen, chromeos_tbmc, and wilco_ec/event
from ACPI drivers to platform drivers.
* Fixes
- Drop wakeup source on remove() in chromeos_tbmc.
* Cleanups
- Simplify workqueue usage with devm in cros_usbpd_logger.
Modules changes for v7.1-rc1
Kernel symbol flags:
- Replace the separate *_gpl symbol sections (__ksymtab_gpl and
__kcrctab_gpl) with a unified symbol table and a new
__kflagstab section. This section stores symbol flags, such as
the GPL-only flag, as an 8-bit bitset for each exported symbol.
This is a cleanup that simplifies symbol lookup in the module
loader by avoiding table fragmentation and will allow a cleaner
way to add more flags later if needed.
Module signature UAPI:
- Move struct module_signature to the UAPI headers to allow reuse
by tools outside the kernel proper, such as kmod and
scripts/sign-file. This also renames a few constants for clarity
and drops unused signature types as preparation for hash-based
module integrity checking work that's in progress.
Sysfs:
- Add a /sys/module/<module>/import_ns sysfs attribute to show
the symbol namespaces imported by loaded modules. This makes it
easier to verify driver API access at runtime on systems that
care about such things (e.g. Android).
Cleanups and fixes:
- Force sh_addr to 0 for all sections in module.lds. This prevents
non-zero section addresses when linking modules with ld.bfd -r,
which confused elfutils.
- Fix a memory leak of charp module parameters on module unload
when the kernel is configured with CONFIG_SYSFS=3Dn.
- Override the -EEXIST error code returned by module_init() to
userspace. This prevents confusion with the errno reserved by
the module loader to indicate that a module is already loaded.
- Simplify the warning message and drop the stack dump on positive
returns from module_init().
- Drop unnecessary extern keywords from function declarations and
synchronize parse_args() arguments with their implementation.

This is exfat update pull request for v7.1-rc1. I add a description of Thanks! Description for this pull request: - Implement FALLOC_FL_ALLOCATE_RANGE to add support for preallocating clusters without zeroing, helping to reduce file fragmentation. - Add a unified block readahead helper for FAT chain conversion, bitmap allocation, and directory entry lookups. - Optimize exfat_chain_cont_cluster() by caching buffer heads to minimize mark_buffer_dirty() and mirroring overhead during NO_FAT_CHAIN to FAT_CHAIN conversion. - Switch to truncate_inode_pages_final() in evict_inode() to prevent BUG_ON caused by shadow entries during reclaim. - Fix a 32-bit truncation bug in directory entry calculations by ensuring proper bitwise coercion. - Fix sb->s_maxbytes calculation to correctly reflect the maximum possible volume size for a given cluster size, resolving xfstests generic/213. - Introduced exfat_cluster_walk() helper to traverse FAT chains by a specified step, handling both ALLOC_NO_FAT_CHAIN and ALLOC_FAT_CHAIN modes. - Introduced exfat_chain_advance() helper to advance an exfat_chain structure, updating both the current cluster and remaining size. - Remove dead assignments and fix Smatch warnings.
A busier cycle than I had expected for docs, including: - Translations: some overdue updates to the Japanese translations, Chinese translations for some of the Rust documentation, and the beginnings of a Portuguese translation. - New documents covering CPU isolation, managed interrupts, debugging Python gbb scripts, and more. - More tooling work from Mauro, reducing docs-build warnings, adding self tests, improving man-page output, bringing in a proper C tokenizer to replace (some of) the mess of kernel-doc regexes, and more. - Update and synchronize changes.rst and scripts/ver_linux, and put both into alphabetical order. ...and a long list of documentation updates, typo fixes, and general improvements. Expect a simple conflict with the Rust tree due to the sorting of Documentation/process/changes.rst.
Thanks,

Update to the VDSO subsystem:
- Make the handling of compat functions consistent and more robust
- Rework the underlying data store so that it is dynamically
allocated, which allows the conversion of the last holdout SPARC64
to the generic VDSO implementation
- Rework the SPARC64 VDSO to utilize the generic implementation
- Mop up the left overs of the non-generic VDSO support in the core
code.
- Expand the VDSO selftest and make them more robust
- Allow time namespaces to be enabled independently of the generic
VDSO support, which was not possible before due to SPARC64 not
using it.

please pull the latest timers/core branch from:
-04-12
Updates for the timer/timekeeping core:
- A rework of the hrtimer subsystem to reduce the overhead for frequently
armed timers, especially the hrtick scheduler timer.
- Better timer locality decision
- Simplification of the evaluation of the first expiry time by
keeping track of the neighbor timers in the RB-tree by providing a
RB-tree variant with neighbor links. That avoids walking the
RB-tree on removal to find the next expiry time, but even more
important allows to quickly evaluate whether a timer which is
rearmed changes the position in the RB-tree with the modified
expiry time or not. If not, the dequeue/enqueue sequence which both
can end up in rebalancing can be completely avoided.
- Deferred reprogramming of the underlying clock event device. This
optimizes for the situation where a hrtimer callback sets the need
resched bit. In that case the code attempts to defer the
re-programming of the clock event device up to the point where the
scheduler has picked the next task and has the next hrtick timer
armed. In case that there is no immediate reschedule or soft
interrupts have to be handled before reaching the reschedule point
in the interrupt entry code the clock event is reprogrammed in one
of those code paths to prevent that the timer becomes stale.
- Support for clocksource coupled clockevents
The TSC deadline timer is coupled to the TSC. The next event is
programmed in TSC time. Currently this is done by converting the
CLOCK_MONOTONIC based expiry value into a relative timeout,
converting it into TSC ticks, reading the TSC adding the delta
ticks and writing the deadline MSR.
As the timekeeping core has the conversion factors for the TSC
already, the whole back and forth conversion can be completely
avoided. The timekeeping core calculates the reverse conversion
factors from nanoseconds to TSC ticks and utilizes the base
timestamps of TSC and CLOCK_MONOTONIC which are updated once per
tick. This allows a direct conversion into the TSC deadline value
without reading the time and as a bonus keeps the deadline
conversion in sync with the TSC conversion factors, which are
updated by adjtimex() on systems with NTP/PTP enabled.
- Allow inlining of the clocksource read and clockevent write
functions when they are tiny enough, e.g. on x86 RDTSC and WRMSR.
With all those enhancements in place a hrtick enabled scheduler
provides the same performance as without hrtick. But also other hrtimer
users obviously benefit from these optimizations.
- Robustness improvements and cleanups of historical sins in the hrtimer
and timekeeping code.
- Rewrite of the clocksource watchdog.
The clocksource watchdog code has over time reached the state of an
impenetrable maze of duct tape and staples. The original design, which was
made in the context of systems far smaller than today, is based on the
assumption that the to be monitored clocksource (TSC) can be trivially
compared against a known to be stable clocksource (HPET/ACPI-PM timer).
Over the years this rather naive approach turned out to have major
flaws. Long delays between the watchdog invocations can cause wrap
arounds of the reference clocksource. The access to the reference
clocksource degrades on large multi-sockets systems dure to
interconnect congestion. This has been addressed with various
heuristics which degraded the accuracy of the watchdog to the point
that it fails to detect actual TSC problems on older hardware which
exposes slow inter CPU drifts due to firmware manipulating the TSC to
hide SMI time.
The rewrite addresses this by:
- Restricting the validation against the reference clocksource to the
boot CPU which is usually closest to the legacy block which
contains the reference clocksource (HPET/ACPI-PM).
- Do a round robin validation betwen the boot CPU and the other CPUs
based only on the TSC with an algorithm similar to the TSC
synchronization code during CPU hotplug.
- Being more leniant versus remote timeouts
- The usual tiny fixes, cleanups and enhancements all over the place

Hi Wolfram, here's the first part of the merge window pull request. It has the usual refactoring, cleanups and updates, with no big surprises. There is also some new hardware support. The main chunks this time are the xiic and rtl9300 work. One patch is already queued for part 2, as it needed some dependencies first and I will keep collecting patches with no major impact. Thanks and enjoy the rest of the weekend, Andi i2c-host for v7.1, part 1 - generic cleanups in npcm7xx, qcom-cci, xiic and designware DT bindings - atr: use kzalloc_flex for alias pool allocation - ixp4xx: convert bindings to DT schema - ocores: use read_poll_timeout_atomic() for polling waits - qcom-geni: skip extra TX DMA TRE for single read messages - s3c24xx: validate SMBus block length before using it - spacemit: refactor xfer path and add K1 PIO support - tegra: identify DVC and VI with SoC data variants - tegra: support SoC-specific register offsets - xiic: switch to devres and generic fw properties - xiic: skip input clock setup on non-OF systems rtl9300: - add per-SoC callbacks and clock support for RTL9607C - add support for new 50 kHz and 2.5 MHz bus speeds - general refactoring in preparation for RTL9607C support New support: - DesignWare GOOG5000 (ACPI HID) - Intel Nova Lake (ACPI ID) - Realtek RTL9607C - SpacemiT K3 binding - Tegra410 register layout support
- Migrate more hash algorithms from the traditional crypto subsystem
to lib/crypto/.
Like the algorithms migrated earlier (e.g. SHA-*), this simplifies
the implementations, improves performance, enables further
simplifications in calling code, and solves various other issues:
- AES CBC-based MACs (AES-CMAC, AES-XCBC-MAC, and AES-CBC-MAC)
- Support these algorithms in lib/crypto/ using the AES
library and the existing arm64 assembly code
- Reimplement the traditional crypto API's "cmac(aes)",
"xcbc(aes)", and "cbcmac(aes)" on top of the library
- Convert mac80211 to use the AES-CMAC library. Note: several
other subsystems can use it too and will be converted later
- Drop the broken, nonstandard, and likely unused support for
"xcbc(aes)" with key lengths other than 128 bits
- Enable optimizations by default
- GHASH
- Migrate the standalone GHASH code into lib/crypto/
- Integrate the GHASH code more closely with the very similar
POLYVAL code, and improve the generic GHASH implementation
to resist cache-timing attacks and use much less memory
- Reimplement the AES-GCM library and the "gcm" crypto_aead
template on top of the GHASH library. Remove "ghash" from
the crypto_shash API, as it's no longer needed
- Enable optimizations by default
- SM3
- Migrate the kernel's existing SM3 code into lib/crypto/, and
reimplement the traditional crypto API's "sm3" on top of it
- I don't recommend using SM3, but this cleanup is worthwhile
to organize the code the same way as other algorithms
- Testing improvements
- Add a KUnit test suite for each of the new library APIs
- Migrate the existing ChaCha20Poly1305 test to KUnit
- Make the KUnit all_tests.config enable all crypto library tests
- Move the test kconfig options to the Runtime Testing menu
- Other updates to arch-optimized crypto code
- Optimize SHA-256 for Zhaoxin CPUs using the Padlock Hash Engine
- Remove some MD5 implementations that are no longer worth keeping
- Drop big endian and voluntary preemption support from the arm64
code, as those configurations are no longer supported on arm64
- Make jitterentropy and samples/tsm-mr use the crypto library APIs
Note: the overall diffstat is neutral, but when the test code is
excluded it is significantly negative:
Tests: 13 files changed, 1982 insertions(+), 888 deletions(-)
Non-test: 141 files changed, 2897 insertions(+), 3987 deletions(-)
All: 154 files changed, 4879 insertions(+), 4875 deletions(-)
- Several improvements related to crc_kunit, to align with the standard KUnit conventions and make it easier for developers and CI systems to run this test suite - Add an arm64-optimized implementation of CRC64-NVME - Remove unused code for big endian arm64
- Various cleanups for the interface between fs/crypto/ and filesystems, from Christoph Hellwig - Simplify and optimize the implementation of v1 key derivation by using the AES library instead of the crypto_skcipher API

There are some "fun" conflicts this time around between the "nested" pull request and kvm/master (RSM fixes, ugh), and a notable oddity: there are two versions of the "svm" pull request: a full version that includes a large set of SEV changes to fix locking bugs and then add a lockdep assertion to guard against similar bugs, and a short version without the SEV changes. I'm including the partial/short version as the SEV changes haven't gotten much soak time in -next, and (AFAIK) haven't been reviewed by anyone. I squeezed them into the initial pull request because the fixes are urgent enough to warrant inclusion in 7.1 no matter what, and the hardening changes largely fall into the category of "these either work or don't". I don't have a strong preference between taking the full version now versus waiting a ~week to give people more time to tell me what I broke. But I do really want to land the hardening sooner than later, e.g. see the rash of SEV+ bugs we've had...
This pull request contains fixes of syzbot reported issues in NILFS2 functionality. The DAT inode's btree node cache (i_assoc_inode) is initialized lazily during btree operations. However, nilfs_mdt_save_to_shadow_map() assumes i_assoc_inode is already initialized when copying dirty pages to the shadow map during GC. If NILFS_IOCTL_CLEAN_SEGMENTS is called immediately after mount before any btree operation has occurred on the DAT inode, i_assoc_inode is NULL leading to a general protection fault. Deepanshu Kartikey has fixed this by calling nilfs_attach_btree_node_cache() on the DAT inode in nilfs_dat_read() at mount time, ensuring i_assoc_inode is always initialized before any GC operation can use it. nilfs_ioctl_mark_blocks_dirty() uses bd_oblocknr to detect dead blocks by comparing it with the current block number bd_blocknr. If they differ, the block is considered dead and skipped. A corrupted ioctl request with bd_oblocknr set to 0 causes the comparison to incorrectly match when the lookup returns -ENOENT and sets bd_blocknr to 0, bypassing the dead block check and calling nilfs_bmap_mark() on a non- existent block. This causes nilfs_btree_do_lookup() to return -ENOENT, triggering the WARN_ON(ret =3D=3D -ENOENT). Deepanshu Kartikey has fixed this by rejecting ioctl requests with bd_oblocknr set to 0 at the beginning of each iteration. nilfs2 updates for v7.1 - nilfs2: reject zero bd_oblocknr in nilfs_ioctl_mark_blocks_dirty() - nilfs2: fix NULL i_assoc_inode dereference in nilfs_mdt_save_to_shadow_map
This pull request contains several fixes of syzbot reported issues and HFS+ fixes of xfstests failures. Deepanshu Kartikey has fixed a syzbot reported issue of a KMSAN uninit-value in hfsplus_strcasecmp(). The root cause is that hfs_brec_read() doesn't validate that the on-disk record size matches the expected size for the record type being read. The fix introduced hfsplus_brec_read_cat() wrapper that validates the record size based on the type field and returns -EIO if size doesn't match. Shardul Bankar has fixed a syzbot reported issue of processing corrupted HFS+ images where the b-tree allocation bitmap indicates that the header node (Node 0) is free. Node 0 must always be allocated. Violating this invariant leads to allocator corruption, which cascades into kernel panics or undefined behavior. Prevent trusting a corrupted allocator state by adding a validation check during hfs_btree_open(). If corruption is detected, print a warning identifying the specific corrupted tree and force the filesystem to mount read-only (SB_RDONLY). This prevents kernel panics from corrupted images while enabling data recovery. Zilin Guan has fixed a potential deadlock in hfsplus_fill_super(). hfsplus_fill_super() calls hfs_find_init() to initialize a search structure, which acquires tree->tree_lock. If the subsequent call to hfsplus_cat_build_key() fails, the function jumps to the out_put_root error label without releasing the lock. Fix this by adding the missing hfs_find_exit(&fd) call before jumping to the out_put_root error label. This ensures that tree->tree_lock is properly released on the error path. Yangtao Li has fixed the issue of not updating the change time after file change. The fix updates file's ctime after rename in hfsplus_rename(). The rest patches introduce the HFS+ fixes for the case of generic/348, generic/728, generic/533, generic/523, and generic/642 test-cases of xfstests suite. hfs/hfsplus updates for v7.1 - hfsplus: fix generic/642 failure - hfsplus: rework logic of map nodes creation in xattr b-tree - hfsplus: fix logic of alloc/free b-tree node - hfsplus: fix error processing issue in hfs_bmap_free() - hfsplus: fix potential race conditions in b-tree functionality - hfsplus: extract hidden directory search into a helper function - hfsplus: fix held lock freed on hfsplus_fill_super() - hfsplus: fix generic/523 test-case failure - hfsplus: validate b-tree node 0 bitmap at mount time - hfsplus: refactor b-tree map page access and add node-type validation - hfsplus: fix to update ctime after rename - hfsplus: fix generic/533 test-case failure - hfsplus: set ctime after setxattr and removexattr - hfsplus: fix uninit-value by validating catalog record size - hfsplus: fix potential Allocation File corruption after fsync
Hi Thomas, - Added the DT bindings for the compatible string 'fsl,imx25-epit' (Frank Li) - Made the rttm_cs variable static for the rtl otto timer driver (Krzysztof Kozlowski) - Fixed error return code handling in the sun5i timer driver (Chen Ni) - Made the timer-of and the mmio code compatible with modules (Daniel Lezcano)
This is the next round of the Rust support.
The biggest "user facing" change is the bump of the minimum Rust version
to follow Debian Stable as we discussed in the Maintainers Summit and
LPC etc.
This carries the two back merges that we discussed -- I have both at the
top of the PR, in case I did something wrong and so that they were
easy to spot. I also merged first the one with the newest base, so that
the second one was obvious. I explained what happened in the merge
commit and used the "temporary merge first" to get the right diffstat
and merge log.
I also talked to my submaintainers so that they know they should avoid
back merges in general. By the way, Tamir has sent me his first PR for
rust-analyzer this cycle, which is included here.
No conflicts expected at this time, but linux-next should generally have
the right resolutions. "Thanks" to the back merge, one of the
conceptually (not mechanically) tricky ones is already solved [1].
All commits have been in linux-next for 3 rounds or more.

Rust changes for v7.1
Toolchain and infrastructure:
- Bump the minimum Rust version to 1.85.0 (and 'bindgen' to 0.71.1).
As proposed in LPC 2025 and the Maintainers Summit [1], we are going
to follow Debian Stable's Rust versions as our minimum versions.
Debian Trixie was released on 2025-08-09 with a Rust 1.85.0 and
'bindgen' 0.71.1 toolchain, which is a fair amount of time for e.g.
kernel developers to upgrade.
Other major distributions support a Rust version that is high enough
as well, including:
+ Arch Linux.
+ Fedora Linux.
+ Gentoo Linux.
+ Nix.
+ openSUSE Slowroll and openSUSE Tumbleweed.
+ Ubuntu 25.10 and 26.04 LTS. In addition, 24.04 LTS using
their versioned packages.
The merged patch series comes with the associated cleanups and
simplifications treewide that can be performed thanks to both bumps,
as well as documentation updates.
In addition, start using 'bindgen''s '--with-attribute-custom-enum'
feature to set the 'cfi_encoding' attribute for the 'lru_status' enum
used in Binder.
Link: https://lwn.net/Articles/1050174/ [1]
- Add experimental Kconfig option ('CONFIG_RUST_INLINE_HELPERS') that
inlines C helpers into Rust.
Essentially, it performs a step similar to LTO, but just for the
helpers, i.e. very local and fast.
It relies on 'llvm-link' and its '--internalize' flag, and requires
a compatible LLVM between Clang and 'rustc' (i.e. same major version,
'CONFIG_RUSTC_CLANG_LLVM_COMPATIBLE'). It is only enabled for two
architectures for now.
The result is a measurable speedup in different workloads that
different users have tested. For instance, for the null block driver,
it amounts to a 2%.
- Support global per-version flags.
While we already have per-version flags in many places, we didn't
have a place to set global ones that depend on the compiler version,
i.e. in 'rust_common_flags', which sometimes is needed to e.g. tweak
the lints set per version.
Use that to allow the 'clippy::precedence' lint for Rust < 1.86.0,
since it had a change in behavior.
- Support overriding the crate name and apply it to Rust Binder, which
wanted the module to be called 'rust_binder'.
- Add the remaining '__rust_helper' annotations (started in the
previous cycle).
'kernel' crate:
- Introduce the 'const_assert!' macro: a more powerful version of
'static_assert!' that can refer to generics inside functions or
implementation bodies, e.g.:
fn f<const N: usize>() {
const_assert!(N > 1);
}
fn g<T>() {
const_assert!(size_of::<T>() > 0, "T cannot be ZST");
}
In addition, reorganize our set of build-time assertion macros
('{build,const,static_assert}!') to live in the 'build_assert'
module.
Finally, improve the docs as well to clarify how these are different
from one another and how to pick the right one to use, and their
equivalence (if any) to the existing C ones for extra clarity.
- 'sizes' module: add 'SizeConstants' trait.
This gives us typed 'SZ_*' constants (avoiding casts) for use in
device address spaces where the address width depends on the hardware
(e.g. 32-bit MMIO windows, 64-bit GPU framebuffers, etc.), e.g.:
let gpu_heap = 14 * u64::SZ_1M;
let mmio_window = u32::SZ_16M;
- 'clk' module: implement 'Send' and 'Sync' for 'Clk' and thus simplify
the users in Tyr and PWM.
- 'ptr' module: add 'const_align_up'.
- 'str' module: improve the documentation of the 'c_str!' macro to
explain that one should only use it for non-literal cases (for the
other case we instead use C string literals, e.g. 'c"abc"').
- Disallow the use of 'CStr::{as_ptr,from_ptr}' and clean one such use
in the 'task' module.
- 'sync' module: finish the move of 'ARef' and 'AlwaysRefCounted'
outside of the 'types' module, i.e. update the last remaining
instances and finally remove the re-exports.
- 'error' module: clarify that 'from_err_ptr' can return 'Ok(NULL)',
including runtime-tested examples.
The intention is to hopefully prevent UB that assumes the result of
the function is not 'NULL' if successful. This originated from a case
of UB I noticed in 'regulator' that created a 'NonNull' on it.
Timekeeping:
- Expand the example section in the 'HrTimer' documentation.
- Mark the 'ClockSource' trait as unsafe to ensure valid values for
'ktime_get()'.
- Add 'Delta::from_nanos()'.
'pin-init' crate:
- Replace the 'Zeroable' impls for 'Option<NonZero*>' with impls of
'ZeroableOption' for 'NonZero*'.
- Improve feature gate handling for unstable features.
- Declutter the documentation of implementations of 'Zeroable' for
tuples.
- Replace uses of 'addr_of[_mut]!' with '&raw [mut]'.
rust-analyzer:
- Add type annotations to 'generate_rust_analyzer.py'.
- Add support for scripts written in Rust ('generate_rust_target.rs',
'rustdoc_test_builder.rs', 'rustdoc_test_gen.rs').
- Refactor 'generate_rust_analyzer.py' to explicitly identify host and
target crates, improve readability, and reduce duplication.
And some other fixes, cleanups and improvements.
This is the batch of pull requests for the v7.1 merge window. This cycle has several new features and a good amount of infrastructure work. There are three new clone3() flags for pidfd-based process lifecycle management. CLONE_AUTOREAP makes a child auto-reap on exit without becoming a zombie. Unlike SA_NOCLDWAIT or SIG_IGN on SIGCHLD this is a per-process property on the child, not a parent-scoped setting affecting all children. The flag survives reparenting so subreaper or init won't need to deal with it. CLONE_NNP sets no_new_privs on the child at clone time, allowing the parent to impose it without affecting itself. CLONE_PIDFD_AUTOKILL ties a child's lifetime to the pidfd returned from clone3() - when the last reference to that struct file is closed the kernel sends SIGKILL to the child. This is useful for container runtimes, service managers, and sandboxed subprocess execution where the child must die if the parent crashes. CLONE_PIDFD_AUTOKILL requires both CLONE_PIDFD and CLONE_AUTOREAP. The pidfd_info struct also gains a coredump_code field. The mount namespace work introduces FSMOUNT_NAMESPACE for fsmount() which creates a new mount namespace with the newly created filesystem attached, returning a namespace fd instead of an O_PATH mount fd. This accompanies last cycle's OPEN_TREE_NAMESPACE and is especially useful when mounting a real filesystem to serve as a container rootfs. Also new is support for creating empty mount namespaces via CLONE_EMPTY_MNTNS for clone3() and UNSHARE_EMPTY_MNTNS for unshare(). These create a namespace containing only a single nullfs root mount with an immutable empty directory. The intended workflow is to mount a real filesystem over the root and build the mount table from scratch, which avoids copying and tearing down the entire parent mount tree. MOVE_MOUNT_BENEATH is extended to target the caller's rootfs and to transfer the MNT_LOCKED property from the top mount to the mount beneath. This allows safely modifying an inherited mount table after unprivileged namespace creation via unshare(CLONE_NEWUSER | CLONE_NEWNS) and makes it possible to switch out the rootfs without pivot_root(2). The simple_xattr subsystem is reworked from an rbtree protected by a reader-writer spinlock to an rhashtable with RCU-based lockless reads. All consumers (shmem, kernfs, pidfs) are converted and the rbtree code is removed. On top of this, user.* extended attributes are now supported on sockets. Sockfs sockets get per-inode limits of 128 xattrs and 128KB total value size. The practical motivation comes from systemd and GNOME expanding their use of Varlink as an IPC mechanism - with user.* xattrs a service can label its socket with the IPC protocol it speaks and eBPF programs can selectively capture traffic on those sockets. The inode->i_ino field is widened from unsigned long to u64. This is a treewide change affecting format strings and tracepoints across 222 files. On 64-bit hosts this makes no material difference but it eliminates the 32-bit hashing hacks various filesystems had to use. Filesystem-level T10 protection information support is added. The existing block layer PI code is refactored to be reusable and wired up through iomap into XFS. This increases read performance up to 15% for 4k I/O compared to the automatic below-the-covers block layer approach. The metadata buffer_head tracking accumulated in struct address_space over the years is cleaned up and moved into filesystem-private inode structures. The private_list, private_data, and private_lock fields are removed from struct address_space, saving 3 longs in struct inode for the vast majority of inodes. The audit subsystem's excessive dput/dget calls during context setup and reset are addressed by adding a pool of extra fs->pwd references to fs_struct. This avoids the spinlock contention on the pwd dentry lock that was causing noticeable performance regressions on systems with many CPUs doing open/close with audit enabled. The directory locking centralization continues. The remaining places where explicit inode_lock(), lock_rename(), or similar are used outside the core VFS are converted to use the start_creating/start_removing/ start_renaming interfaces. The biggest changes are in overlayfs, with smaller conversions in cachefiles, nfsd, apparmor, and selinux. lock_rename(), lock_rename_child(), and unlock_rename() are unexported. The writeback subsystem gets new helper APIs and f2fs, gfs2, and nfs are converted to stop accessing writeback internals directly. Smaller items include namespace helper macros (FOR_EACH_NS_TYPE(), CLONE_NS_ALL), FAT timestamp conversion KUnit tests, removal of unused fs_context infrastructure now that the conversion is finished, a fix for architecture-specific compat_ftruncate64 enforcing the non-LFS file size limit, trivial ->setattr rename cleanups, dcache bucket count fixes, mbcache shrink work ordering fix, omfs superblock validation, a coredump tracepoint, dirent_size() helper, scoped user access conversion, runtime const for file/bfile caches, and permitting dynamic_dname()s up to NAME_MAX. Thanks! Christian

This goes early because I will be traveling next week. acpi-7.1-rc1 Merge branch 'acpi-apei' Linux 7.0-rc7 to receive ACPI support updates for 7.1-rc1. These include an update of the CMOS RTC driver and the related ACPI and x86 code that, among other things, switches it over to using the platform device interface for device binding on x86 instead of the PNP device driver interface (which allows the code in question to be simplified quite a bit), a major update of the ACPI Time and Alarm Device (TAD) driver adding an RTC class device interface to it, and updates of core ACPI drivers that remove some unnecessary and not really useful code from them. Apart from that, two drivers are converted to using the platform driver interface for device binding instead of the ACPI driver one, which is slated for removal, support for the Performance Limited register is added to the ACPI CPPC library and there are some janitorial updates of it and the related cpufreq CPPC driver, the ACPI processor driver is fixed and cleaned up, and NVIDIA vendor CPER record handler is added to the APEI GHES code.

This goes early because I will be traveling next week. pm-7.1-rc1 Merge branch 'pm-devfreq' Linux 7.0-rc7 to receive power management updates for 7.1-rc1. Once again, cpufreq is the most active development area, mostly because of the new feature additions and documentation updates in the amd-pstate driver, but there are also changes in the cpufreq core related to boost support and other assorted updates elsewhere. Next up are power capping changes due to the major cleanup of the Intel RAPL driver.

I'll be OoO next week and disconnected so I'm sending an early PR for the next cycle. For this release we have an extension of the pwrseq-pcie-m2 driver with support for PCIe M.2 Key E connectors. The rest of the commits in the PR fulfill a supporting role: document the hardware in DT bindings, provide required serdev helpers (this has been provided in an immutable branch to Rob Herring so you may see it in his PR as well) and is followed up by some Kconfig fixes from Arnd. Please consider pulling for v7.1-rc1. Thanks, Bartosz power sequencing updates for v7.1-rc1 - add support for the PCIe M.2 Key E connectors in pwrseq-pcie-m2 - describe PCIe M.2 Mechanical Key E connectors in DT bindings - add serdev helpers for looking up devices by OF nodes - minor serdev core rework to enable support for PCIe M.2 Key E connectors
I'll be OoO next week and disconnected so I'm sending an early PR for the next cycle. For this merge window we have two new drivers: support for GPIO-signalled ACPI events on Intel platforms and a generic GPIO-over-pinctrl driver using the ARM SCMI protocol for controlling pins. Several things have been reworked in GPIO core: we unduplicated GPIO hog handling, reduced the number of SRCU locks and dereferences, improved support for software-node-based lookup and removed more legacy code after converting remaining users to modern alternatives. There's also a number of driver reworks and refactoring, documentation updates, some bug-fixes and new tests. The merges in this PR are as follows: immutable branch provided to the net tree with driver changes prerequisite to legacy code removal, pinctrl changes pulled ahead of adding the SCMI GPIO driver and an immutable branch with a high-risk GPIO core fix that was then pulled into the for-current branch and sent for v7.0 after spending some time in linux-next with no regressions. Details are in the signed tag. Please consider pulling for v7.1-rc1. Thanks, Bartosz gpio updates for v7.1-rc1 GPIO core: - defer probe on software node lookups when the remote software node exists but has not been registered as a firmware node yet - unify GPIO hog handling by moving code duplicated in OF and ACPI modules into GPIO core and allow setting up hogs with software nodes - allow matching GPIO controllers by secondary firmware node if matching by primary does not succeed - demote deferral warnings to debug level as they are quite normal when using software nodes which don't support fw_devlink yet - disable the legacy GPIO character device uAPI v1 supprt in Kconfig by default - rework several core functions in preparation for the upcoming Revocable helper library for protecting resources against sudden removal, this reduces the number of SRCU dereferences in GPIO core - simplify file descriptor logic in GPIO character device code by using FD_PREPARE() - introduce a header defining symbols used by both GPIO consumers and providers to avoid having to include provider-specific headers from drivers which only consume GPIOs - replace snprintf() with strscpy() where formatting is not required New drivers: - add the gpio-by-pinctrl generic driver using the ARM SCMI protocol to control GPIOs (along with SCMI changes pulled from the pinctrl tree) - add a driver providing support for handling of platform events via GPIO-signalled ACPI events (used on Intel Nova Lake and later platforms) Driver changes: - extend the gpio-kempld driver with support for more recent models, interrupts and setting/getting multiple values at once - improve interrupt handling in gpio-brcmstb - add support for multi-SoC systems in gpio-tegra186 - make sure we return correct values from the .get() callbacks in several GPIO drivers by normalizing any values other than 0, 1 or negative error numbers - use flexible arrays in several drivers to reduce the number of required memory allocations - simplify synchronous waiting for virtual drivers to probe and remove the dedicated, a bit overengineered helper library dev-sync-probe - remove unneeded Kconfig dependencies on OF_GPIO in several drivers and subsystems - convert the two remaining users of of_get_named_gpio() to using GPIO descriptors and remove the (no longer used) function along with the header that declares it - add missing includes in gpio-mmio - shrink and simplify code in gpio-max732x by using guard(mutex) - remove duplicated code handling the 'ngpios' property from gpio-ts4800, it's already handled in GPIO core - use correct variable type in gpio-aspeed - add support for a new model in gpio-realtek-otto - allow to specify the active-low setting of simulated hogs over the configfs interface (in addition to existing devicetree support) in gpio-sim Bug fixes: - clear the OF_POPULATED flag on hog nodes in GPIO chip remove path on OF systems - fix resource leaks in error path in gpiochip_add_data_with_key() - drop redundant device reference in gpio-mpsse Tests: - add selftests for use-after-free cases in GPIO character device code DT bindings: - add a DT binding document for SCMI based, gpio-over-pinctrl devices - fix interrupt description in microchip,mpfs-gpio - add new compatible for gpio-realtek-otto - describe the resets of the mpfs-gpio controller - fix maintainer's email in gpio-delay bindings - remove the binding document for cavium,thunder-8890 as the corresponding device is bound over PCI and not firmware nodes Documentation: - update the recommended way of converting legacy boards to using software nodes for GPIO description - describe GPIO line value semantics - misc updates to kerneldocs Misc: - convert OMAP1 ams-delta board to using GPIO hogs described with software nodes
Hi,
please pull the following btrfs updates. Thanks.
User visible changes:
- move shutdown ioctl support out of experimental features, a forced stop
of filesystem operation until the next unmount; additionally there's a
super block operation to forcibly remove a device from under the
filesystem that could lead to a shutdown or not if the redundancy allows
that
- report filesystem shutdown using fserror mechanism
- tree-checker updates:
- verify free space info, extent and bitmap items
- verify remap-tree items and related data in block group items
Performance improvements:
- speed up clearing first extent in the tracked range (+10% throughput on
sample workload)
- reduce COW rewrites of extent buffers during the same transaction
- avoid taking big device lock to update device stats during transaction
commit
- fix unnecessary flush on close when truncating empty files (observed
in practice on a backup application)
- prevent direct reclaim during compressed readahead to avoid stalls
under memory pressure
Notable fixes:
- fix chunk allocation strategy on RAID1-like block groups with
disproportionate device sizes, this could lead to ENOSPC due to skewed
reservation estimates
- adjust metadata reservation overcommit ratio to be less aggressive and
also try to flush if possible, this avoids ENOSPC and potential
transaction aborts in some edge cases (that are otherwise hard to
reproduce)
- fix silent IO error in encoded writes and ordered extent split in zoned
mode, the error was not correctly propagated to the address space and
could lead to zeroed ranges
- don't mark inline files NOCOMPRESS unexpectedly, the intent was to do
that for single block writes of regular files
- fix deadlock between reflink and transaction commit when using
flushoncommit
- fix overly strict item check of a running dev-replace operation
Core:
- zoned mode space reservation fixes:
- cap delayed refs metadata reservation to avoid overcommit
- update logic to reclaim partially unusable zones
- add another state to flush and reclaim partially used zone
- limit number of zones reclaimed in one go to avoid blocking other
operations
- don't let log trees consume global reserve on overcommit and fall back
to transaction commit
- revalidate extent buffer when checking its up-to-date status
- add self tests for zoned mode block group specifics
- reduce atomic allocations in some qgroup paths
- avoid unnecessary root node COW during snapshotting
- start new transaction in block group relocation conditionally
- faster check of NOCOW files on currently snapshotted root
- change how compressed bio size is tracked from bio and reduce the
structure size
- new tracepoint for search slot restart tracking
- checksum list manipulation improvements
- type, parameter cleanups, refactoring
- error handling improvements, transaction abort call adjustments

Hey folks, Thanks, Conor. RISC-V soc drivers for v7.1 Microchip: Add coverage for the pic64gx in the system controller and syscons. Add a interrupt mux driver (akin to the one that Renesas recently added) that fixes a problem where the platform never properly modelled gpio interrupts. There's a gpio driver change here that Bartosz has acked that adds the interrupt support to the GPIO driver itself. Signed-off-by: Conor Dooley <[email protected]>
Hey folks, Realised as I was tagging this that the tsu clock and gpio interrupts changes miss the pic64gx and should have been rebased. I'll send another PR later this week I think, with those two fixes. Nothing is broken by the two fixes, they just didn't fix the newly added dts, which is why I still feel comfortable sending this, particularly given I am pretty late already. My excuse is that I was sick all last week... Cheers, Conor. RISC-V devicetrees for v7.1 Generic: Add binding coverage for Supm. Microchip: Add support for the picgx64 and its curiosity board. This is a PolarFire SoC without the FPGA. Add the missing tsu_clk for ptp on the macb on PolarFire SoC and resolve a long-running problem with gpio interrupts being incorrectly described on the platform.

Steve, rv changes for v7.1 (for-next) Summary of changes: - Refactor da_monitor header to share handlers across monitor types No functional changes, only less code duplication. - Add Hybrid Automata model class Add a new model class that extends deterministic automata by adding constraints on transitions and states. Those constraints can take into account wall-clock time and as such allow RV monitor to make assertions on real time. Add documentation and code generation scripts. - Add stall monitor as hybrid automaton example Add a monitor that triggers a violation when a task is stalling as an example of automaton working with real time variables. - Convert the opid monitor to a hybrid automaton The opid monitor can be heavily simplified if written as a hybrid automaton: instead of tracking preempt and interrupt enable/disable events, it can just run constraints on the preemption/interrupt states when events like wakeup and need_resched verify. - Add support for per-object monitors in DA/HA Allow writing deterministic and hybrid automata monitors for generic objects (e.g. any struct), by exploiting a hash table where objects are saved. This allows to track more than just tasks in RV. For instance it will be used to track deadline entities in deadline monitors. - Add deadline tracepoints and move some deadline utilities Prepare the ground for deadline monitors by defining events and exporting helpers. - Add nomiss deadline monitor Add first example of deadline monitor asserting all entities complete before their deadline. - Improve rvgen error handling Introduce AutomataError exception class and better handle expected exceptions while showing a backtrace for unexpected ones. - Improve python code quality in rvgen Refactor the rvgen generation scripts to align with python best practices: use f-strings instead of %, use len() instead of __len__(), remove semicolons, use context managers for file operations, fix whitespace violations, extract magic strings into constants, remove unused imports and methods. - Fix small bugs in rvgen The generator scripts presented some corner case bugs: logical error in validating what a correct dot file looks like, fix an isinstance() check, enforce a dot file has an initial state, fix type annotations and typos in comments. - rvgen refactoring Refactor automata.py to use iterator-based parsing and handle required arguments directly in argparse. - Allow epoll in rtapp-sleep monitor The epoll_wait call is now rt-friendly so it should be allowed in the sleep monitor as a valid sleep method.
Once the merge window opens, please pull the following RCU changes for v7.1. RCU changes for v7.1 NOCB CPU management: - Consolidate rcu_nocb_cpu_offload() and rcu_nocb_cpu_deoffload() to reduce code duplication. - Extract nocb_bypass_needs_flush() helper to reduce duplication in NOCB bypass path. rcutorture/torture infrastructure: - Add NOCB01 config for RCU_LAZY torture testing. - Add NOCB02 config for NOCB poll mode testing. - Add TRIVIAL-PREEMPT config for textbook-style preemptible RCU torture. - Test call_srcu() with preemption both disabled and enabled. - Remove kvm-check-branches.sh in favor of kvm-series.sh. - Make hangs more visible in torture.sh output. - Add informative message for tests without a recheck file. - Fix numeric test comparison in srcu_lockdep.sh. - Use torture_shutdown_init() in refscale and rcuscale instead of open-coded shutdown functions. - Fix modulo-zero error in torture_hrtimeout_ns().

Hi Rob! power sequencing updates for the M.2 driver. Thanks Bartosz Immutable branch between the pwrseq and serdev trees for v7.1-rc1 Provide new serdev helper for looking up controllers by their OF node to be used in the power sequencing driver for the PCIe M.2 connector.
Hi Dave and Sima,
There's quite a lot of stuff in here this time. The highlights are GPU budd=
y
and GEM shmem abstractions on the DRM core side; RPC continuation records, =
the
missing Turing pieces, exposed GSP log buffers in debugfs, and lots of gene=
ral
refactorings and improvements on the nova-core side.
Among the latter I want to highlight the generic kernel register!() macro a=
nd
the DMA improvements.
There are also quite a few external dependencies in here. Besides a few Rus=
t
core and minor workqueue changes, I took all the DMA changes through this t=
ree
for this cycle and merged a shared signed tag from the driver-core tree for
register!() and other I/O improvements.
(I plan to send an early driver-core PR to Linus for this cycle, since I al=
so
gave out two other signed tags for other trees.)
All changes have been in linux-next for at least one round -- no conflicts
expected.

DRM Rust changes for v7.1-rc1
- DMA:
- Rework the DMA coherent API: introduce Coherent<T> as a generalized
container for arbitrary types, replacing the slice-only
CoherentAllocation<T>. Add CoherentBox for memory initialization
before exposing a buffer to hardware (converting to Coherent when
ready), and CoherentHandle for allocations without kernel mapping.
- Add Coherent::init() / init_with_attrs() for one-shot initialization
via pin-init, and from-slice constructors for both Coherent and
CoherentBox
- Add uaccess write_dma() for copying from DMA buffers to userspace
and BinaryWriter support for Coherent<T>
- DRM:
- Add GPU buddy allocator abstraction
- Add DRM shmem GEM helper abstraction
- Allow drm::Device to dispatch work and delayed work items to driver
private data
- Add impl_aref_for_gem_obj!() macro to reduce GEM refcount
boilerplate, and introduce DriverObject::Args for constructor
context
- Add dma_resv_lock helper and raw_dma_resv() accessor on GEM objects
- Clean up imports across the DRM module
- I/O:
- Merged via a signed tag from the driver-core tree: register!() macro
and I/O infrastructure improvements (IoCapable refactor, RelaxedMmio
wrapper, IoLoc trait, generic accessors, write_reg /
LocatedRegister)
- Nova (Core):
- Fix and harden the GSP command queue: correct write pointer
advancing, empty slot handling, and ring buffer indexing; add mutex
locking and make Cmdq a pinned type; distinguish wait vs no-wait
commands
- Add support for large RPCs via continuation records, splitting
oversized commands across multiple queue slots
- Simplify GSP sequencer and message handling code: remove unused
trait and Display impls, derive Debug and Zeroable where applicable,
warn on unconsumed message data
- Refactor Falcon firmware handling: create DMA objects lazily, add
PIO upload support, and use the Generic Bootloader to boot FWSEC on
Turing
- Convert all register definitions (PMC, PBUS, PFB, GC6, FUSE, PDISP,
Falcon) to the kernel register!() macro; add bounded_enum macro to
define enums usable as register fields
- Migrate all DMA usage to the new Coherent, CoherentBox, and
CoherentHandle APIs
- Harden firmware parsing with checked arithmetic throughout FWSEC,
Booter, RISC-V parsing paths
- Add debugfs support for reading GSP-RM log buffers; replace
module_pci_driver!() with explicit module init to support
module-level debugfs setup
- Fix auxiliary device registration for multi-GPU systems
- Various cleanups: import style, firmware parsing refactoring,
framebuffer size logging
- Rust:
- Add interop::list module providing a C linked list interface
- Extend num::Bounded with shift operations, into_bool(), and const
get() to support register bitfield manipulation
- Enable the generic_arg_infer Rust feature and add EMSGSIZE error
code
- Tyr:
- Adopt vertical import style per kernel Rust guidelines
- Clarify driver/device type names and use DRM device type alias
consistently across the driver
- Fix GPU model/version decoding in GpuInfo
- Workqueue:
- Add ARef<T> support for work and delayed work
Two minor improvements that weren't ready when I sent the originall pull request. They have now been tested in next. No problem if it is too late for this cycle. Thanks, Drew T-HEAD Devicetrees for 7.1, part 2 Additional updates to T-Head device trees for v7.1: - Enable the display pipeline for the TH1520-based BeagleV Ahead board by adding the HDMI connector node, connecting it to the HDMI controller, and activating the DPU and HDMI nodes. - Add coefficients to the TH1520 PVT node as the values in the TH1520 manual differ from the defaults in the driver.
Steven, please pull the following changes for RTLA (more info in tag description). Thanks, Tomas RTLA patches for v7.1 - Simplify option parsing Auto-generate getopt_long() optstring for short options from long options array, avoiding the need to specify it manually and reducing the surface for mistakes. - Add unit tests Implement unit tests (make unit-tests) using libcheck, next to existing runtime tests (make check). Currently, three functions from utils.c are tested. - Add --stack-format option In addition to stopping stack pointer decoding (with -s/--stack option) on first unresolvable pointer, allow also skipping unresolvable pointers and displaying everything, configurable with a new option. - Unify number of CPUs into one global variable Use one global variable, nr_cpus, to store the number of CPUs instead of retrieving it and passing it at multiple places. - Fix behavior in various corner cases Make RTLA behave correctly in several corner cases: memory allocation failure, invalid value read from kernel side, thread creation failure, malformed time value input, and read/write failure or interruption by signal. - Improve string handling Simplify several places in the code that handle strings, including parsing of action arguments. A few new helper functions and variables are added for that purpose. - Get rid of magic numbers Few places handling paths use a magic number of 1024. Replace it with MAX_PATH and ARRAY_SIZE() macro. - Unify threshold handling Code that handles response to latency threshold is duplicated between tools, which has led to bugs in the past. Unify it into a new helper as much as possible. - Fix segfault on SIGINT during cleanup The SIGINT handler touches dynamically allocated memory. Detach it before freeing it during cleanup to prevent segmentation fault and discarding of output buffers. Also, properly document SIGINT handling while at it. The tag was tested (make && make check && make unit-tests) as well as pre-tested on top of next-20260326. There are no known conflicts. Signed-off-by: Tomas Glozar <[email protected]>

Just the one Nuvoton devicetree change for v7.1 Andrew nuvoton: first batch of arm64 devicetree changes for v7.1 Just the one change this time, dropping syscon properties where they weren'= t defined.
Here's the first batch of ASPEED devicetree changes for v7.1. Cheers, Andrew aspeed: first batch of devicetree changes for v7.1 New platforms: - Asus Kommando IPMI card - Asrock Paul IPMI card Updated platforms: - Anacapa (Meta): NFC and EEPROMs - MSX4 (Nvidia): 128M layout for the alternate boot flash
Memory controller drivers for v7.1 1. TegraMC: - Few fixes for older issues - missing clock on Tegra264, missing enabling of DLL for Tegra30 and Tegra124. - Simplify the code in a few places. - Rework handling interrupts on different variants and add support for error logging on Tegra 264. 2. Drop Baikal SoC bt1-l2-ctl driver, because SoC support is being removed tree-wide.
Samsung SoC drivers for v7.1 Few cleanups in ACPM firmware drivers, used on Google GS101 and newer Samsung Exynos SoCs. Notable change is removing 'const' in 'struct acpm_handle' pointers, because even though the code does not modify pointed data, it immediately drops the const via cast. Also code is not logically readable when a reference getters/putters (e.g. acpm_handle_put()) take a pointer to const, because the meaning of "get" and "put" implies changing the memory, even if that changeable field is outside of pointed data.
Hi Stephen, This pull request introduces support for the Tenstorrent Atlantis RISC-V SoC in the form of a clk driver, reset driver and the associated DT binding. The reset driver was reviewed by Philipp, who agreed that it could go via the clk tree. Brian reviewed the clk driver but there is no review/ack from you. Please let me know if you'd like to see any changes and we will post a new revision. clk: tenstorrent: Add support for Atlantis PRCM Introduce support for the clock and reset controllers (e.g. PRCM) in the Tenstorrent Atlantis SoC. 5 types of clocks are generated by the PRCM: PLLs, shared gates and standard muxes. The reset controller is setup as an auxiliary device of the clock controller. Signed-off-by: Drew Fustini <[email protected]>
T-HEAD Devicetrees for 7.1 Update the T-Head TH1520 RISC-V SoC device tree to support the Verisilicon DC8200 display controller (called DPU in manual) and the Synopsys DesignWare HDMI TX controller. In addition, enable HDMI output for the LicheePi 4a board. Signed-off-by: Drew Fustini <[email protected]>
Hi Stephen, Here's a pull for some fixes and improvements for the clk subsystem that's been posted over the last month. Details are in the signed git tag. I didn't include any new drivers, or changes where it looks like there is a submaintainer that typically sends you a pull separately. Improvements to the clk core - Add support for clk spread spectrum, which reduces electromagnetic interference (EMI) by modulating the clk frequency a small amount to spread the energy across a wider bandwidth. The SCMI clk driver uses this new functionality. (Peng Fan) - Introduced the CLK_ROUNDING_NOOP flag, which is for the case where the determine_rate op is an empty function. This typically occurs when rounding is managed by firmware or the clock is capable of any rate. Nine clk drivers were updated to use this new flag: rp1, scpi, hisilicon/hi3660-stub, imx/clk-scu, qcom/clk-rpm, qcom/clk-rpmh, qcom/clk-smd-rpm, samsung/clk-acpm, sprd/pll. (Brian Masney) - Added kernel docs for all members of struct clk_core. (Brian Masney) - Simplify clk_is_match() and improve readability. (Geert Uytterhoeven) Remove deprecated APIs (all Brian Masney) - Converts clk-composite from round_rate() to determine_rate(). - Removes the round_rate() clk op. - Removes the deprecated functions divider_round_rate(), divider_round_rate_parent(), and divider_ro_round_rate_parent() since these are just wrappers for the corresponding determine_rate variant. KUnit Tests - Add tests for clk lookup by name. (Chen-Yu Tsai) - Introduced kunit tests for spread spectrum. (Peng Fan) - Minor cleanup to use HZ_PER_MHZ. (Brian Masney) Driver-specific updates not listed above - The SCMI driver gained support for OEM extensions. (Peng Fan) - Dropped the baikal-t1 SoC that will not be finalized / supported. (Andy Shevchenko) - Minor bug fixes / cleanups to various drivers across the clk tree: aspeed/ast2700 (Felix Gu), x86/lpss-atom (Andy Shevchenko), hisilicon/reset (Shawn Guo), hisilicon (J. Neuschäfer), xgene (Geert Uytterhoeven), mvebu/armada-37xx-periph (Ben Dooks), imx/scu (Brian Masney).
Jakub, convert the remaining users of of_gpio.h under drivers/nfc and the last one removes the - now unused - header. Thanks, Bartosz Immutable branch between GPIO and net Convert remaining users of of_gpio.h to using GPIO descriptors and remove the header.
