VFIO updates for v6.13
- Constify an unmodified structure used in linking vfio and kvm.
(Christophe JAILLET)
- Add ID for an additional hardware SKU supported by the nvgrace-gpu
vfio-pci variant driver. (Ankit Agrawal)
- Fix incorrect signed cast in QAT vfio-pci variant driver, negating
test in check_add_overflow(), though still caught by later tests.
(Giovanni Cabiddu)
- Additional debugfs attributes exposed in hisi_acc vfio-pci variant
driver for migration debugging. (Longfang Liu)
- Migration support is added to the virtio vfio-pci variant driver,
becoming the primary feature of the driver while retaining emulation
of virtio legacy support as a secondary option. (Yishai Hadas)
- Fixes to a few unwind flows in the mlx5 vfio-pci driver discovered
through reviews of the virtio variant driver. (Yishai Hadas)
- Fix an unlikely issue where a PCI device exposed to userspace with
an unknown capability at the base of the extended capability chain
can overflow an array index. (Avihai Horon)

Modules changes for v6.13-rc1
Highlights for this merge window:
* The whole caching of module code into huge pages by Mike Rapoport is going
in through Andrew Morton's tree due to some other code dependencies. That's
really the biggest highlight for Linux kernel modules in this release. With
it we share huge pages for modules, starting off with x86. Expect to see that
soon through Andrew!
* Helge Deller addressed some lingering low hanging fruit alignment
enhancements by. It is worth pointing out that from his old patch series
I dropped his vmlinux.lds.h change at Masahiro's request as he would
prefer this to be specified in asm code [0].
[0] https://lore.kernel.org/all/20240129192644.3359978-5-mcgrof@kernel.org/T/#m9efef5e700fbecd28b7afb462c15eed8ba78ef5a
* Matthew Maurer and Sami Tolvanen have been tag teaming to help
get us closer to a modversions for Rust. In this cycle we take in
quite a lot of the refactoring for ELF validation. I expect modversions
for Rust will be merged by v6.14 as that code is mostly ready now.
* Adds a new modules selftests: kallsyms which helps us tests find_symbol()
and the limits of kallsyms on Linux today.
* We have a realtime mailing list to kernel-ci testing for modules now
which relies and combines patchwork, kpd and kdevops:
- https://patchwork.kernel.org/project/linux-modules/list/
- https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/README.md
- https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/kernel-ci-kpd.md
- https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/linux-modules-kdevops-ci.md
If you want to help avoid Linux kernel modules regressions, now its simple,
just add a new Linux modules sefltests under tools/testing/selftests/module/
That is it. All new selftests will be used and leveraged automatically by
the CI.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Make pci_stop_dev() and pci_destroy_dev() safe so concurrent
callers can't stop a device multiple times, even as we migrate from
the global pci_rescan_remove_lock to finer-grained locking (Keith
Busch)
- Improve pci_walk_bus() implementation by making it recursive and
moving locking up to avoid need for a 'locked' parameter (Keith
Busch)
- Unexport pci_walk_bus_locked(), which is only used internally by
the PCI core (Keith Busch)
- Detect some Thunderbolt chips that are built-in and hence
'trustworthy' by a heuristic since the 'ExternalFacingPort' and
'usb4-host-interface' ACPI properties are not quite enough (Esther
Shimanovich)
Resource management:
- Use PCI bus addresses (not CPU addresses) in 'ranges' properties
when building dynamic DT nodes so systems where PCI and CPU
addresses differ work correctly (Andrea della Porta)
- Tidy resource sizing and assignment with helpers to reduce
redundancy (Ilpo Järvinen)
- Improve pdev_sort_resources() 'bogus alignment' warning to be more
specific (Ilpo Järvinen)
Driver binding:
- Convert driver .remove_new() callbacks to .remove() again to finish
the conversion from returning 'int' to being 'void' (Sergio
Paracuellos)
- Export pcim_request_all_regions(), a managed interface to request
all BARs (Philipp Stanner)
- Replace pcim_iomap_regions_request_all() with
pcim_request_all_regions(), and pcim_iomap_table()[n] with
pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
(Philipp Stanner)
- Remove the now unused pcim_iomap_regions_request_all() (Philipp
Stanner)
- Export pcim_iounmap_region(), a managed interface to unmap and
release a PCI BAR (Philipp Stanner)
- Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
cavium (Philipp Stanner)
Error handling:
- Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
bridge; previously Secondary Bus Reset could only be used when
there was a single device below a bridge (Keith Busch)
- Warn if we reset a running device where the driver didn't register
pci_error_handlers notification callbacks (Keith Busch)
ASPM:
- Disable ASPM L1 before touching L1 PM Substates to follow the spec
closer and avoid a CPU load timeout on some platforms (Ajay
Agarwal)
- Set devices below Intel VMD to D0 before enabling ASPM L1 Substates
as required per spec for all L1 Substates changes (Jian-Hong Pan)
Power management:
- Enable starfive controller runtime PM before probing host bridge
(Mayank Rana)
- Enable runtime power management for host bridges (Krishna chaitanya
chundru)
Power control:
- Use of_platform_device_create() instead of of_platform_populate()
to create pwrctl platform devices so we can control it based on the
child nodes (Manivannan Sadhasivam)
- Create pwrctrl platform devices only if there's a relevant power
supply property (Manivannan Sadhasivam)
- Add device link from the pwrctl supplier to the PCI dev to ensure
pwrctl drivers are probed before the PCI dev driver; this avoids a
race where pwrctl could change device power state while the PCI
driver was active (Manivannan Sadhasivam)
- Find pwrctl device for removal with of_find_device_by_node()
instead of searching all children of the parent (Manivannan
Sadhasivam)
- Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
('bwctrl') and hotplug files (Bjorn Helgaas)
Bandwidth control:
- Add read/modify/write locking for Link Control 2, which is used to
manage Link speed (Ilpo Järvinen)
- Extract Link Bandwidth Management Status check into
pcie_lbms_seen(), where it can be shared between the bandwidth
controller and quirks that use it to help retrain failed links
(Ilpo Järvinen)
- Re-add Link Bandwidth notification support with updates to address
the reasons it was previously reverted (Alexandru Gagniuc, Ilpo
Järvinen)
- Add pcie_set_target_speed() and related functionality so drivers
can manage PCIe Link speed based on thermal or other constraints
(Ilpo Järvinen)
- Add a thermal cooling driver to throttle PCIe Links via the
existing thermal management framework (Ilpo Järvinen)
- Add a userspace selftest for the PCIe bandwidth controller (Ilpo
Järvinen)
PCI device hotplug:
- Add hotplug controller driver for Marvell OCTEON multi-function
device where function 0 has a management console interface to
enable/disable and provision various personalities for the other
functions (Shijith Thotton)
- Retain a reference to the pci_bus for the lifetime of a pci_slot to
avoid a use-after-free when the thunderbolt driver resets USB4 host
routers on boot, causing hotplug remove/add of downstream docks or
other devices (Lukas Wunner)
- Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
(Guilherme Giacomo Simoes)
- Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)
- Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
detection in cpqphp (Ilpo Järvinen)
- Simplify cpqphp enumeration, which is already simple-minded and
doesn't handle devices below hot-added bridges (Ilpo Järvinen)
Virtualization:
- Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
capability but do isolate functions as though PCI_ACS_RR and
PCI_ACS_CR were set, so the functions can be in independent IOMMU
groups (Mengyuan Lou)
TLP Processing Hints (TPH):
- Add and document TLP Processing Hints (TPH) support so drivers can
enable and disable TPH and the kernel can save/restore TPH
configuration (Wei Huang)
- Add TPH Steering Tag support so drivers can retrieve Steering Tag
values associated with specific CPUs via an ACPI _DSM to improve
performance by directing DMA writes closer to their consumers (Wei
Huang)
Data Object Exchange (DOE):
- Wait up to 1 second for DOE Busy bit to clear before writing a
request to the mailbox to avoid failures if the mailbox is still
busy from a previous transfer (Gregory Price)
Endpoint framework:
- Skip attempts to allocate from endpoint controller memory window if
the requested size is larger than the window (Damien Le Moal)
- Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to
handle controller-specific size and alignment constraints, and add
test cases to the endpoint test driver (Damien Le Moal)
- Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can
observe DWC-specific alignment requirements (Damien Le Moal)
- Synchronously cancel command handler work in endpoint test before
cleaning up DMA and BARs (Damien Le Moal)
- Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas
Cassel)
- Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
(Niklas Cassel)
- Avoid NULL dereference if Modem Host Interface Endpoint lacks
'mmio' DT property (Zhongqiu Han)
- Release PCI domain ID of Endpoint controller parent (not controller
itself) and before unregistering the controller, to avoid
use-after-free (Zijun Hu)
- Clear secondary (not primary) EPC in pci_epc_remove_epf() when
removing the secondary controller associated with an NTB (Zijun Hu)
Cadence PCIe controller driver:
- Lower severity of 'phy-names' message (Bartosz Wawrzyniak)
Freescale i.MX6 PCIe controller driver:
- Fix suspend/resume support on i.MX6QDL, which has a hardware
erratum that prevents use of L2 (Stefan Eichenberger)
Intel VMD host bridge driver:
- Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 DT binding to require the exact number of
clocks for each SoC (Fei Shao)
- Add support for DT 'max-link-speed' and 'num-lanes' properties to
restrict the link speed and width (AngeloGioacchino Del Regno)
Microchip PolarFlare PCIe controller driver:
- Add DT and driver support for using either of the two PolarFire
Root Ports (Conor Dooley)
NVIDIA Tegra194 PCIe controller driver:
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
Qualcomm PCIe controller driver:
- Add qcom SAR2130P DT binding with an additional clock (Dmitry
Baryshkov)
- Enable MSI interrupts if 'global' IRQ is supported, since a
previous commit unintentionally masked them (Manivannan Sadhasivam)
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
- Add DT binding and driver support for IPQ9574, with Synopsys IP
v5.80a and Qcom IP 1.27.0 (devi priya)
- Move the OPP "operating-points-v2" table from the
qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it
can be used by other Qcom platforms (Qiang Yu)
- Add 'global' SPI interrupt for events like link-up, link-down to
qcom,pcie-x1e80100 DT binding so we can start enumeration when the
link comes up (Qiang Yu)
- Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned
to support this (Qiang Yu)
- Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
'iommu-map' DT property and doesn't need BDF-to-SID translation
(Qiang Yu)
Rockchip PCIe controller driver:
- Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint
.align value (Damien Le Moal)
- When unmapping an endpoint window, compute the region index instead
of searching for it, and verify that the address was mapped (Damien
Le Moal)
- When mapping an endpoint window, verify that the address hasn't
been mapped already (Damien Le Moal)
- Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)
- Fix MSI IRQ data mapping to observe the alignment constraint, which
fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
(Damien Le Moal)
- Rename rockchip_pcie_parse_ep_dt() to
rockchip_pcie_ep_get_resources() for consistency with similar DT
interfaces (Damien Le Moal)
- Skip the unnecessary link train in rockchip_pcie_ep_probe() and do
it only in the endpoint start operation (Damien Le Moal)
- Implement pci_epc_ops.stop_link() to disable link training and
controller configuration (Damien Le Moal)
- Attempt link training at 5 GT/s when both partners support it
(Damien Le Moal)
- Add a handler for PERST# signal so we can detect host-initiated
resets and start link training after PERST# is deasserted (Damien
Le Moal)
Synopsys DesignWare PCIe controller driver:
- Clear outbound address on unmap so dw_pcie_find_index() won't match
an ATU index that was already unmapped (Damien Le Moal)
- Use of_property_present() instead of of_property_read_bool() when
testing for presence of non-boolean DT properties (Rob Herring)
- Advertise 1MB size if endpoint supports Resizable BARs, which was
inadvertently lost in v6.11 (Niklas Cassel)
TI J721E PCIe driver:
- Add PCIe support for J722S SoC (Siddharth Vadapalli)
- Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100
us), before deasserting PERST# to ensure power and refclk are
stable (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root
Complex mode (Kishon Vijay Abraham I)
- Try to avoid unrecoverable SError for attempts to issue config
transactions when the link is down; this is racy but the best we
can do (Kishon Vijay Abraham I)
Miscellaneous:
- Reorganize kerneldoc parameter names to match order in function
signature (Julia Lawall)
- Fix sysfs reset_method_store() memory leak (Todd Kjos)
- Simplify pci_create_slot() (Ilpo Järvinen)

rust: fix up formatting after merge
When I merged the rust 'use' imports, I didn't realize that there's an offical preferred idiomatic format - so while it all worked fine, it doesn't match what 'make rustfmt' wants to make it.

perf tools changes for v6.13
perf record
-----------
* Enable leader sampling for inherited task events. It was supported
only for system-wide events but the kernel started to support such a
setup since v6.12.
This is to reduce the number of PMU interrupts. The samples of the
leader event will contain counts of other events and no samples will
be generated for the other member events.
$ perf record -e '{cycles,instructions}:S' ${MYPROG}
perf report
-----------
* Fix --branch-history option to display more branch-related information
like prediction, abort and cycles which is available on Intel machines.

perf stat
---------
* Add HWMON PMU support. The HWMON provides various system information
like CPU/GPU temperature, fan speed and so on. Expose them as PMU
events so that users can see the values using perf stat commands.
$ perf stat -e temp_cpu,fan1 true
Performance counter stats for 'true':

0 rpm fan1
0.000745382 seconds time elapsed

0.000000000 seconds sys
* Display metric threshold in JSON output. Some metrics define
thresholds to classify value ranges. It used to be in a different
color but it won't work for JSON. Add "metric-threshold" field to
the JSON that can be one of "good", "less good", "nearly bad" and
"bad".

Build
-----
* Make libunwind opt-in (LIBUNWIND=1) rather than opt-out. The perf
tools are generally built with libelf and libdw which has unwinder
functionality. The libunwind support predates it and no need to
have duplicate unwinders by default.
* Rename NO_DWARF=1 build option to NO_LIBDW=1 in order to clarify it's
using libdw for handling DWARF information.
Internals
---------
* Do not set exclude_guest bit in the perf_event_attr by default. This
was causing a trouble in AMD IBS PMU as it doesn't support the bit.
The bit will be set when it's needed later by the fallback logic.
Also update the missing feature detection logic to make sure not clear
supported bits unnecessarily.
* Run perf test in parallel by default and mark flaky tests "exclusive"
to run them serially at the end. Some test numbers are changed but
the test can complete in less than half the time.
JSON vendor events
------------------
* Add AMD Zen 5 events and metrics.
* Add i.MX91 and i.MX95 DDR metrics
* Fix HiSilicon HIP08 Topdown metric name.
* Support compat events on PowerPC.

Rust changes for v6.13
Toolchain and infrastructure:
- Enable a series of lints, including safety-related ones, e.g. the
compiler will now warn about missing safety comments, as well as
unnecessary ones. How safety documentation is organized is a frequent
source of review comments, thus having the compiler guide new
developers on where they are expected (and where not) is very nice.
- Start using '#[expect]': an interesting feature in Rust (stabilized
in 1.81.0) that makes the compiler warn if an expected warning was
_not_ emitted. This is useful to avoid forgetting cleaning up locally
ignored diagnostics ('#[allow]'s).
- Introduce '.clippy.toml' configuration file for Clippy, the Rust
linter, which will allow us to tweak its behaviour. For instance, our
first use cases are declaring a disallowed macro and, more
importantly, enabling the checking of private items.
- Lints-related fixes and cleanups related to the items above.
- Migrate from 'receiver_trait' to 'arbitrary_self_types': to get the
kernel into stable Rust, one of the major pieces of the puzzle is the
support to write custom types that can be used as 'self', i.e. as
receivers, since the kernel needs to write types such as 'Arc' that
common userspace Rust would not. 'arbitrary_self_types' has been
accepted to become stable, and this is one of the steps required to
get there.
- Remove usage of the 'new_uninit' unstable feature.
- Use custom C FFI types. Includes a new 'ffi' crate to contain our
custom mapping, instead of using the standard library 'core::ffi'
one. The actual remapping will be introduced in a later cycle.
- Map '__kernel_{size_t,ssize_t,ptrdiff_t}' to 'usize'/'isize' instead
of 32/64-bit integers.
- Fix 'size_t' in bindgen generated prototypes of C builtins.
- Warn on bindgen < 0.69.5 and libclang >= 19.1 due to a double issue
in the projects, which we managed to trigger with the upcoming
tracepoint support. It includes a build test since some distributions
backported the fix (e.g. Debian -- thanks!). All major distributions
we list should be now OK except Ubuntu non-LTS.
'macros' crate:
- Adapt the build system to be able run the doctests there too; and
clean up and enable the corresponding doctests.
'kernel' crate:
- Add 'alloc' module with generic kernel allocator support and remove
the dependency on the Rust standard library 'alloc' and the extension
traits we used to provide fallible methods with flags.
Add the 'Allocator' trait and its implementations '{K,V,KV}malloc'.
Add the 'Box' type (a heap allocation for a single value of type 'T'
that is also generic over an allocator and considers the kernel's GFP
flags) and its shorthand aliases '{K,V,KV}Box'. Add 'ArrayLayout'
type. Add 'Vec' (a contiguous growable array type) and its shorthand
aliases '{K,V,KV}Vec', including iterator support.
For instance, now we may write code such as:
let mut v = KVec::new();
v.push(1, GFP_KERNEL)?;
assert_eq!(&v, &[1]);
Treewide, move as well old users to these new types.
- 'sync' module: add global lock support, including the
'GlobalLockBackend' trait; the 'Global{Lock,Guard,LockedBy}' types
and the 'global_lock!' macro. Add the 'Lock::try_lock' method.
- 'error' module: optimize 'Error' type to use 'NonZeroI32' and make
conversion functions public.
- 'page' module: add 'page_align' function.
- Add 'transmute' module with the existing 'FromBytes' and 'AsBytes'
traits.
- 'block::mq::request' module: improve rendered documentation.
- 'types' module: extend 'Opaque' type documentation and add simple
examples for the 'Either' types.
drm/panic:
- Clean up a series of Clippy warnings.
Documentation:
- Add coding guidelines for lints and the '#[expect]' feature.
- Add Ubuntu to the list of distributions in the Quick Start guide.
MAINTAINERS:
- Add Danilo Krummrich as maintainer of the new 'alloc' module.
And a few other small cleanups and fixes.

'ArrayLayout' type. Add 'Vec' (a contiguous growable array type)
and its shorthand aliases '{K,V,KV}Vec', including iterator
support.
For instance, now we may write code such as:
let mut v = KVec::new();
v.push(1, GFP_KERNEL)?;
assert_eq!(&v, &[1]);
Treewide, move as well old users to these new types.
- 'sync' module: add global lock support, including the
'GlobalLockBackend' trait; the 'Global{Lock,Guard,LockedBy}' types
and the 'global_lock!' macro. Add the 'Lock::try_lock' method.
- 'error' module: optimize 'Error' type to use 'NonZeroI32' and make
conversion functions public.
- 'page' module: add 'page_align' function.
- Add 'transmute' module with the existing 'FromBytes' and 'AsBytes'
traits.
- 'block::mq::request' module: improve rendered documentation.
- 'types' module: extend 'Opaque' type documentation and add simple
examples for the 'Either' types.
drm/panic:
- Clean up a series of Clippy warnings.
Documentation:
- Add coding guidelines for lints and the '#[expect]' feature.

Here's a description of the basic C semantics and how they are mapped to Rust. The pid namespace of a task doesn't ever change once the task is alive. A unshare(CLONE_NEWPID) or setns(fd_pidns/pidfd, CLONE_NEWPID) will not have an effect on the calling task's pid namespace. It will only effect the pid namespace of children created by the calling task. This invariant guarantees that after having acquired a reference to a task's pid namespace it will remain unchanged. When a task has exited and been reaped release_task() will be called. This will set the pid namespace of the task to NULL. So retrieving the pid namespace of a task that is dead will return NULL. Note, that neither holding the RCU lock nor holding a reference count to the task will prevent release_task() from being called. In order to retrieve the pid namespace of a task the task_active_pid_ns() function can be used. There are two cases to consider: (1) retrieving the pid namespace of the current task (2) retrieving the pid namespace of a non-current task From system call context retrieving the pid namespace for case (1) is always safe and requires neither RCU locking nor a reference count to be held. Retrieving the pid namespace after release_task() for current will return NULL but no codepath like that is exposed to Rust. Retrieving the pid namespace from system call context for (2) requires RCU protection. Accessing a pid namespace outside of RCU protection requires a reference count that must've been acquired while holding the RCU lock. Note that accessing a non-current task means NULL can be returned as the non-current task could have already passed through release_task(). To retrieve (1) the current_pid_ns!() macro should be used. It ensures that the returned pid namespace cannot outlive the calling scope. The associated current_pid_ns() function should not be called directly as it could be abused to created an unbounded lifetime for the pid namespace. The current_pid_ns!() macro allows Rust to handle the common case of accessing current's pid namespace without RCU protection and without having to acquire a reference count. For (2) the task_get_pid_ns() method must be used. This will always acquire a reference on the pid namespace and will return an Option to force the caller to explicitly handle the case where pid namespace is None. Something that tends to be forgotten when doing the equivalent operation in C. Missing RCU primitives make it difficult to perform operations that are otherwise safe without holding a reference count as long as RCU protection is guaranteed. But it is not important currently. But we do want it in the future. Note that for (2) the required RCU protection around calling task_active_pid_ns() synchronizes against putting the last reference of the associated struct pid of task->thread_pid. The struct pid stored in that field is used to retrieve the pid namespace of the caller. When release_task() is called task->thread_pid will be NULLed and put_pid() on said struct pid will be delayed in free_pid() via call_rcu() allowing everyone with an RCU protected access to the struct pid acquired from task->thread_pid to finish" * tag 'vfs-6.13.rust.pid_namespace' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: rust: add PidNamespace |

NFSD 6.13 Release Notes
Jeff Layton contributed a scalability improvement to NFSD's NFSv4 backchannel session implementation. This improvement is intended to increase the rate at which NFSD can safely recall NFSv4 delegations from clients, to avoid the need to revoke them. Revoking requires a slow state recovery process. A wide variety of bug fixes and other incremental improvements make up the bulk of commits in this series. As always I am grateful to the NFSD contributors, reviewers, testers, and bug reporters who participated during this cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmdEgLQACgkQM2qzM29m f5cwmg/9HcfG7blepU/2qNHopzSYRO5vZw1YNJQ5/Wi3bmqIea83lf8OcCY1G/aj 6K+jnenzHrwfhaA4u7N2FPXPVl8sPSMuOrJXY5zC4yE5QnIbranjcyEW5l5zlj3n ukkTYQgjUsKre3pHlvn3JmDHfUhNPEfzirsJeorP7DS3omne+OFA1LNncNP6emRu h0aEC6EJ43zUkYiz9nZYqPwIAwrUIA0WOrvVnq7vsi6gR4/Muk7nS+X/y4qFjli3 9enVskEv8sFmmOAIMK3CHJq+exEeKtKEKUuYkD23QgPt2R4+IwqS70o9IM/S1ypf APiv958BIhxm/SwUn1IjoxIckTB5EdksMxU5/4qGr1ZxprPG4/ruKO80BkrxLzW2 n1HmJ4ZNnpWPQvHN7RQ0WOsPNzL8byxJbGr1bpNgU4AGXnTFWPrAnB6juiyX4xb+ YNfgkQGDY79o7r1OJ5UUdCyx0QBSnaLNACTGm2u2FpI/ukMFPdrWIE99QbBgSe1p MgWaiPwSY+9crFfGPJeQ4t6/siRAec6L3RO9KT9Epcd2S7/Uts3NXYRdJfwZ+Qza TkPY2bm7T/WCcMhW7DN372hqgfRHPWOf4tacJ1Tob+As1d6p6qXEX2zi6piCCOLj dmTVDSVPClRXt8YigF9WqosyWv1jUzSnh9ne+eYPBpj93Ag2YBY= =wBvS -----END PGP SIGNATURE----- Merge tag 'nfsd-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Jeff Layton contributed a scalability improvement to NFSD's NFSv4 backchannel session implementation.

- introduce device aliasing file
- add stats in debugfs to show multiple devices
- add a sysfs node to limit max read extent count per-inode
- modify f2fs_is_checkpoint_ready logic to allow more data to be written with the CP disable
- decrease spare area for pinned files for zoned devices
Bug fix:
- Revert "f2fs: remove unreachable lazytime mount option parsing"
- adjust unusable cap before checkpoint=disable mode
- fix to drop all discards after creating snapshot on lvm device
- fix to shrink read extent node in batches
- fix changing cursegs if recovery fails on zoned device
- fix to adjust appropriate length for fiemap
- fix fiemap failure issue when page size is 16KB
- fix to avoid forcing direct write to use buffered IO on inline_data inode

LoongArch has supported PREEMPT_RT now. It uses GENERIC_ENTRY, so just add the TIF bit (TIF_NEED_RESCHED_LAZY) related definitions and select the Kconfig symbol (ARCH_HAS_PREEMPT_LAZY) is enough to make it go.

LoongArch: Allow to enable PREEMPT_RT
It is really time. LoongArch has all the required architecture related changes, that have been identified over time, in order to enable PREEMPT_RT. With the recent printk changes, the last known road block has been addressed. Allow to enable PREEMPT_RT on LoongArch. Below are the latency data from cyclictest on a 4-core Loongson-3A5000 machine, with a "make -j8" kernel building workload in the background. 1. PREEMPT kernel with default configuration: ./cyclictest -a -t -m -i200 -d0 -p99 policy: fifo: loadavg: 8.78 8.96 8.64 10/296 64800 T: 0 ( 4592) P:99 I:200 C:14838617 Min: 3 Act: 6 Avg: 8 Max: 844 T: 1 ( 4593) P:99 I:200 C:14838765 Min: 3 Act: 9 Avg: 8 Max: 909 T: 2 ( 4594) P:99 I:200 C:14838510 Min: 3 Act: 7 Avg: 8 Max: 832 T: 3 ( 4595) P:99 I:200 C:14838631 Min: 3 Act: 8 Avg: 8 Max: 931 2.

LoongArch: Reduce min_delta for the arch clockevent device
Now the min_delta is 0x600 (1536) for LoongArch's constant clockevent device. For a 100MHz hardware timer this means ~15us. This is a little big, especially for PREEMPT_RT enabled kernels. So reduce it to 100 for PREEMPT_RT kernel, and 1000 for others (we don't want too small values to affect performance). Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> |

LoongArch: BPF: Sign-extend return values
(1) Description of Problem:
When testing BPF JIT with the latest compiler toolchains on LoongArch,
there exist some strange failed test cases, dmesg shows something like
this:
# dmesg -t | grep FAIL | head -1
... ret -3 != -3 (0xfffffffd != 0xfffffffd)FAIL ...
(2) Steps to Reproduce:
# echo 1 > /proc/sys/net/core/bpf_jit_enable
# modprobe test_bpf
(3) Additional Info:
There are no failed test cases compiled with the lower version of GCC
such as 13.3.0, while the problems only appear with higher version of
GCC such as 14.2.0.
This is because the problems were hidden by the lower version of GCC due
to redundant sign extension instructions generated by compiler, but with
optimization of higher version of GCC, the sign extension instructions
have been removed.
(4) Root Cause Analysis:
The LoongArch architecture does not expose sub-registers, and hold all
32-bit values in a sign-extended format. While BPF, on the other hand,
exposes sub-registers, and use zero-extension (similar to arm64/x86).
This has led to some subtle bugs, where a BPF JITted program has not
sign-extended the a0 register (return value in LoongArch land), passed
the return value up the kernel, for example:
| int from_bpf(void);
|
| long foo(void)
| {
| return from_bpf();
| }
Here, a0 would be 0xffffffff instead of the expected 0xffffffffffffffff.
Internally, the LoongArch JIT uses a5 as a dedicated register for BPF
return values. That is to say, the LoongArch BPF uses a5 for BPF return
values, which are zero-extended, whereas the LoongArch ABI uses a0 which
is sign-extended.
(5) Final Solution:
Keep a5 zero-extended, but explicitly sign-extend a0 (which is used
outside BPF land). Because libbpf currently defines the return value
of an ebpf program as a 32-bit unsigned integer, just use addi.w to
extend bit 31 into bits 63 through 32 of a5 to a0. This is similar to

LoongArch: Explicitly specify code model in Makefile
LoongArch's toolchain may change the default code model from normal to medium. This is unnecessary for kernel, and generates some relocations which cannot be handled by the module loader. So explicitly specify the code model to normal in Makefile (for Rust 'normal' is 'small').

i2c-for-6.13-part2
Andi was super busy the last weeks, so this pull requests contains one
series (nomadik) and a number of smaller additions which were ready to
go but nearly overlooked. Despite the late collection, they have been
properly reviewed and have been in -next for 6 days now in Andi's tree.
New feature support:
- Added support for frequencies up to 3.4 MHz on Nomadik I2C.
- DesignWare now accounts for bus capacitance and clock
optimisation (declared as new parameters in the binding) to
improve the calculation of signal rise and fall times
(t_high and t_low).
New Hardware support:
- DWAPB I2C controller on FUJITSU-MONAKA (new ACPI HID).
- Allwinner A523 (new compatible ID).
- Mobileye EyeQ6H (new compatible ID).
