VFIO updates for v6.19-rc1
- Move libvfio selftest artifacts in preparation of more tightly
coupled integration with KVM selftests. (David Matlack)
- Fix comment typo in mtty driver. (Chu Guangqing)
- Support for new hardware revision in the hisi_acc vfio-pci variant
driver where the migration registers can now be accessed via the PF.
When enabled for this support, the full BAR can be exposed to the
user. (Longfang Liu)
- Fix vfio cdev support for VF token passing, using the correct size
for the kernel structure, thereby actually allowing userspace to
provide a non-zero UUID token. Also set the match token callback for
the hisi_acc, fixing VF token support for this this vfio-pci variant
driver. (Raghavendra Rao Ananta)
- Introduce internal callbacks on vfio devices to simplify and
consolidate duplicate code for generating VFIO_DEVICE_GET_REGION_INFO
data, removing various ioctl intercepts with a more structured
solution. (Jason Gunthorpe)
- Introduce dma-buf support for vfio-pci devices, allowing MMIO regions
to be exposed through dma-buf objects with lifecycle managed through
move operations. This enables low-level interactions such as a
vfio-pci based SPDK drivers interacting directly with dma-buf capable
RDMA devices to enable peer-to-peer operations. IOMMUFD is also now
able to build upon this support to fill a long standing feature gap
versus the legacy vfio type1 IOMMU backend with an implementation of
P2P support for VM use cases that better manages the lifecycle of the
P2P mapping. (Leon Romanovsky, Jason Gunthorpe, Vivek Kasireddy)
- Convert eventfd triggering for error and request signals to use RCU
mechanisms in order to avoid a 3-way lockdep reported deadlock issue.
(Alex Williamson)
- Fix a 32-bit overflow introduced via dma-buf support manifesting with
large DMA buffers. (Alex Mastro)
- Convert nvgrace-gpu vfio-pci variant driver to insert mappings on
fault rather than at mmap time. This conversion serves both to make
use of huge PFNMAPs but also to both avoid corrected RAS events
during reset by now being subject to vfio-pci-core's use of
unmap_mapping_range(), and to enable a device readiness test after
reset. (Ankit Agrawal)
- Refactoring of vfio selftests to support multi-device tests and split
code to provide better separation between IOMMU and device objects.
This work also enables a new test suite addition to measure parallel
device initialization latency. (David Matlack)

IOMMU Updates for Linux v6.19
Including:
- Introduction of the generic IO page-table framework with support for
Intel and AMD IOMMU formats from Jason. This has good potential for
unifying more IO page-table implementations and making future
enhancements more easy. But this also needed quite some fixes during
development. All known issues have been fixed, but my feeling is that
there is a higher potential than usual that more might be needed.
- Intel VT-d updates:
- Use right invalidation hint in qi_desc_iotlb().
- Reduce the scope of INTEL_IOMMU_FLOPPY_WA.
- ARM-SMMU updates:
- Qualcomm device-tree binding updates for Kaanapali and Glymur SoCs
and a new clock for the TBU.
- Fix error handling if level 1 CD table allocation fails.
- Permit more than the architectural maximum number of SMRs for funky
Qualcomm mis-implementations of SMMUv2.
- Mediatek driver:
- MT8189 iommu support.
- Move ARM IO-pgtable selftests to kunit.
- Device leak fixes for a couple of drivers.
- Random smaller fixes and improvements.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Enable host bridge emulation for PCI_DOMAINS_GENERIC platforms (Dan
Williams)
- Switch vmd from custom domain number allocator to the common
allocator to prevent a potential race with new non-VMD buses (Dan
Williams)
- Enable Precision Time Measurement (PTM) only if device advertises
support for a relevant role, to prevent invalid PTM Requests that
cause ACS violations that are reported as AER Uncorrectable
Non-Fatal errors (Mika Westerberg)
Resource management:
- Prevent resource tree corruption when BAR resize fails (Ilpo
Järvinen)
- Restore BARs to the original size if a BAR resize fails (Ilpo
Järvinen)
- Remove BAR release from BAR resize attempts by the xe, i915, and
amdgpu drivers so the PCI core can restore BARs if the resize fails
(Ilpo Järvinen)
- Move Resizable BAR code to rebar.c (Ilpo Järvinen)
- Add pci_rebar_size_supported() and use it in i915 and xe (Ilpo
Järvinen)
- Add pci_rebar_get_max_size() and use it in xe and amdgpu (Ilpo
Järvinen)
Power management and error handling:
- For drivers using PCI legacy suspend, save config state at suspend
so that state (not any earlier state from enumeration, probe, or
error recovery) will be restored when resuming (Lukas Wunner)
- For devices with no driver or a driver that lacks power management,
save config state at hibernate so that state (not any earlier state
from enumeration, probe, or error recovery) will be restored when
resuming (Lukas Wunner)
- Save device config space on device addition, before driver binding,
so error recovery works more reliably (Lukas Wunner)
- Drop pci_save_state() from several drivers that no longer need it
since the PCI core always does it and pci_restore_state() no longer
invalidates the saved state (Lukas Wunner)
- Document use of pci_save_state() by drivers to capture the state
they want restored during error recovery (Lukas Wunner)
Power control:
- Add a struct pci_ops.assert_perst() function pointer to
assert/deassert PCIe PERST# and implement it for the qcom driver
(Krishna Chaitanya Chundru)
- Add DT binding and pwrctrl driver for the Toshiba TC9563 PCIe
switch, which must be held in reset after poweron so the pwrctrl
driver can configure the switch via I2C before bringing up the
links (Krishna Chaitanya Chundru)
Endpoint framework:
- Convert the endpoint doorbell test to use a threaded IRQ to fix a
'sleeping while atomic' issue (Bhanu Seshu Kumar Valluri)
- Add endpoint VNTB MSI doorbell support to reduce latency between
host and endpoint (Frank Li)
New native PCIe controller drivers:
- Add CIX Sky1 host controller DT binding and driver (Hans Zhang)
- Add NXP S32G host controller DT binding and driver (Vincent
Guittot)
- Add Renesas RZ/G3S host controller DT binding and driver (Claudiu
Beznea)
- Add SpacemiT K1 host controller DT binding and driver (Alex Elder)
Amlogic Meson PCIe controller driver:
- Update DT binding to name DBI region 'dbi', not 'elbi', and update
driver to support both (Manivannan Sadhasivam)
Apple PCIe controller driver:
- Move struct pci_host_bridge allocation from pci_host_common_init()
to callers, which significantly simplifies pcie-apple (Marc
Zyngier)
Broadcom STB PCIe controller driver:
- Disable advertising ASPM L0s support correctly (Jim Quinlan)
- Add a panic/die handler to print diagnostic info in case PCIe
caused an unrecoverable abort (Jim Quinlan)
Cadence PCIe controller driver:
- Add module support for Cadence platform host and endpoint
controller driver (Manikandan K Pillai)
- Split headers into 'legacy' (LGA) and 'high perf' (HPA) to prepare
for new CIX Sky1 driver (Manikandan K Pillai)
MediaTek PCIe controller driver:
- Convert DT binding to YAML schema (Christian Marangi)
- Add Airoha AN7583 DT compatible and driver support (Christian
Marangi)
Qualcomm PCIe controller driver:
- Add Qualcomm Kaanapali to SM8550 DT binding (Qiang Yu)
- Add required 'power-domains' and 'resets' to qcom sa8775p, sc7280,
sc8280xp, sm8150, sm8250, sm8350, sm8450, sm8550, x1e80100 DT
schemas (Krzysztof Kozlowski)
- Look up OPP using both frequency and data rate (not just frequency)
so RPMh votes can account for both (Krishna Chaitanya Chundru)
Rockchip DesignWare PCIe controller driver:
- Add Rockchip RK3528 compatible strings in DT binding (Yao Zi)
STMicroelectronics STM32MP25 PCIe controller driver:
- Fix a race between link training and endpoint register
initialization (Christian Bruel)
- Align endpoint allocations to match the ATU requirements (Christian
Bruel)
Synopsys DesignWare PCIe controller driver:
- Clear L1 PM Substate Capability 'Supported' bits unless glue driver
says it's supported, which prevents users from enabling non-working
L1SS. Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)
- Remove now-superfluous L1SS disable code from tegra194 (Bjorn
Helgaas)
- Configure L1SS support in dw-rockchip when DT says
'supports-clkreq' (Shawn Lin)
TI Keystone PCIe controller driver:
- Fail the probe instead of silently succeeding if ks_pcie_of_data
didn't specify Root Complex or Endpoint mode (Siddharth Vadapalli)
- Make keystone buildable as a loadable module, except on ARM32 where
hook_fault_code() is __init (Siddharth Vadapalli)"

EFI updates for v6.19:
- Parse SMBIOS tables in memory directly on Macbooks that do not
implement the EFI SMBIOS protocol
- Obtain EDID information from the primary display while running in the
EFI stub, and expose it via bootparams on x86 (generic method is in
the works, and will likely land during the next cycle)
- Bring CPER handling for ARM systems up to data with the latest EFI
spec changes.
- Various cosmetic changes.

gpio updates for v6.19-rc1
GPIO core:
- add proper support for shared GPIOs that's aiming to replace the
current sharing mechanism (which provides no synchronization ot enable
counting) and enable it for Qualcomm platforms
- improve the software node GPIO lookup by using the fwnode
representation instead of the software node's name which was prone to
bugs (GPIO controllers don't have to use the software node's name as
their kernel label)
- remove the last user of legacy-of-mm-gpiochip.h and drop the header
- move closer to removing the legacy gpio_request_one() routine
- rename some symbols for consistency
- shrink GPIO printk() helpers by reusing existing code
- remove some redundant kernel messages
- use min() instead of min_t() in GPIO ACPI code
- use system_percpu_wq instead of system_wq in GPIO character device code
New drivers:
- add a driver for the QIXIS FPGA GPIO controller
Driver improvements:
- use modernized variants of power management macros across a wide array
of drivers in order to avoid having to use the __maybe_unused attribute
- convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
instead of the platform bus as they are not really described in
firmware
- use lock guards and update symbol prefixes in gpio-mmio
- support the bryx radio interface kit in gpio-mpsse + refactor the
driver
- use software nodes for configuring the reset-gpio driver, including
setting up the reference to the shared "reset" pin
- check and propagate the return value of gpiod_set_value() to user-space
in gpio-virtuser (this was previously not possible as this function
returned void)
- extend the gpio-regmap helper with more features (bypass cache for
aliased inputs, force writes for aliased data registers, add a new
configuration parameter)
- remove unneeded includes from gpio-aspeed and gpio-latch
- add support for Tegra410 to gpio-tegra186
- replace PCI-specific PM with generic device-level PM in gpio-bt8xx
- use dynamic GPIO range allocation in gpio-loongson-64bit
- improve handling of level-triggered interrupts in gpio-pca953x
- add suspend/resume support to gpio-fxl6408
- add support for more models to gpio-menz127
- optimize gpio-mvebu interrupt handling by avoiding unnecessary calls
to mvebu_gpio_irq_handler()
- make locking more consistent in gpio-grgpio
Device-tree bindings:
- document new NXP and Microchip models
Documentation:
- add a comprehensive compatibility and feature list for gpio-pca953x,
which is a great addition as it's probably the most commonly used GPIO
expander driver
- kernel-doc tweaks
Late fixes:
- use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson

refactoring support for new models and misc tweaks and fixes.
The biggest new feature in GPIO core is adding support for managed,
enable-counted sharing of GPIO pins, something that - until now - was
only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag
which basically allowed drivers to "fight it out" for the descriptor
and provided no synchronization. It was enabled on Qualcomm platforms
(and thus is enabled on arm64 defconfig) and I plan on removing
GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to
the new mechanism.
GPIO core:
- add proper support for shared GPIOs that's aiming to replace the
current sharing mechanism (which provides no synchronization ot
enable counting) and enable it for Qualcomm platforms
- improve the software node GPIO lookup by using the fwnode
representation instead of the software node's name which was prone
to bugs (GPIO controllers don't have to use the software node's
name as their kernel label)
- remove the last user of legacy-of-mm-gpiochip.h and drop the header
- move closer to removing the legacy gpio_request_one() routine
- rename some symbols for consistency
- shrink GPIO printk() helpers by reusing existing code
- remove some redundant kernel messages
- use min() instead of min_t() in GPIO ACPI code
- use system_percpu_wq instead of system_wq in GPIO character device
code
New drivers:
- add a driver for the QIXIS FPGA GPIO controller
Driver improvements:
- use modernized variants of power management macros across a wide
array of drivers in order to avoid having to use the __maybe_unused
attribute
- convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
instead of the platform bus as they are not really described in
firmware
- use lock guards and update symbol prefixes in gpio-mmio
- support the bryx radio interface kit in gpio-mpsse + refactor the
driver
- use software nodes for configuring the reset-gpio driver, including
setting up the reference to the shared "reset" pin
- check and propagate the return value of gpiod_set_value() to
user-space in gpio-virtuser (this was previously not possible as
this function returned void)
- extend the gpio-regmap helper with more features (bypass cache for
aliased inputs, force writes for aliased data registers, add a new
configuration parameter)
- remove unneeded includes from gpio-aspeed and gpio-latch
- add support for Tegra410 to gpio-tegra186
- replace PCI-specific PM with generic device-level PM in gpio-bt8xx
- use dynamic GPIO range allocation in gpio-loongson-64bit
- improve handling of level-triggered interrupts in gpio-pca953x
- add suspend/resume support to gpio-fxl6408
- add support for more models to gpio-menz127
- optimize gpio-mvebu interrupt handling by avoiding unnecessary
calls to mvebu_gpio_irq_handler()
- make locking more consistent in gpio-grgpio
Device-tree bindings:
- document new NXP and Microchip models
Documentation:
- add a comprehensive compatibility and feature list for
gpio-pca953x, which is a great addition as it's probably the most
commonly used GPIO expander driver
- kernel-doc tweaks
Late fixes:
- use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson"

firewire updates for v6.19
This release includes two changes for core functions, which affects all
use cases of this subsystem.
- Handle per-device interoperability quirks
It is well known that some devices have quirks affecting
interoperability. To identify such quirks at an early stages of
device detection, the step for reading the configuration ROM contents
has been changed. As a side effect, the entire detection process is
now performed at the basic transaction speed (S100), without no trial
to probe higher supported speeds.
With this change, the following devices should now work with fewer
issues:
- TASCAM FW-1884, FW-1804, and FW-1082
- MOTU Audio Express
- Safer removals of host card
There was a race condition between host card removal and handling of
bus reset events in the workqueue. This appears to be a long standing
issue (for a dozen years or so[1]), and recent changes to use more
workqueues escalate it. To solve it, a new callback has been added to
the 1394 OHCI PCI driver to unregister the interrupt sources and wait
for workqueue completions when removing a card instance.

spi: Updates for v6.19
This release is almost entirely new drivers, with a couple of small
changes in generic code. The biggest individual update is a rename of
the existing Microchip driver and the addition of a new driver for the
silicon SPI controller in their PolarFire SoCs. The overlap between the
soft IP supported by the current driver and this new one is regrettably
all in the IP and not in the register interface offered to software.
- Add a time offset parameter for offloads, allowing them to be defined
in relation to each other. This is useful for IIO type applcations
where you trigger an operation then read the result after a delay.
- Add a tracepoint for flash exec_ops, bringing the flash support more
in line with the debuggability of vanilla SPI.
- Support for Airoha EN7523, Arduino MCUs, Aspeed AST2700, Microchip
PolarFire SPI controllers, NXP i.MX51 ECSPI target mode, Qualcomm
IPQ5414 and IPQ5332, Renesas RZ/T2H, RZ/V2N and RZ/2NH and SpacemiT K1
QuadSPI.
There's also a small set of ASoC cleanups that I mistakenly applied to
the SPI tree and then put more stuff on top of before it was brought to
my attention, sorry about that.

regulator: Updates for v6.19
This is a relatively busy release for the regulator API, as well as a
good collection of new drivers we've got a little bit of core work and a
bunch of cleanup throughout the subsystem:
- Support for propagating undervoltage events to child regulators.
- Undo enables done on supplies when setting enabling regulators via
constraints fails.
- Pull in some gpiolib changes adding support for shared GPIOs to
the gpiolib core, using them to replace the open coded variant of this
that we've had in the regulator API for a long time.
- Support for Fitipower FP9931 and JD9330, Mediatek MT6316, MT6363 and
MT6373, NXP PF1550 and Qualcomm PMH01XX and PMCX0102
The PF1550 support was originally going to go via the MFD tree but
Krzysztof's cleanup work overlapped with it so I pulled in Lee's signed
tag with support for the device.

regmap: Updates for v6.19
Another small update for regmap, we have one new feature plus a little
bit of cleanup:
- Support for sparseness information in the flat cache, allowing users
that really need the performance properties it provides to benefit
from the interface and startup time improvements that sparsness provides
without needing to go all the way to a more fancy data structure.
- Cleanup work from Andy Shevchenko, refactoring the cache interface
in preparation for some future stuff he's working on.

"Another small update for regmap, we have one new feature plus a little
bit of cleanup:
- Support for sparseness information in the flat cache, allowing
users that really need the performance properties it provides to
benefit from the interface and startup time improvements that
sparsness provides without needing to go all the way to a more
fancy data structure
- Cleanup work from Andy Shevchenko, refactoring the cache interface
in preparation for some future stuff he's working on"

Core MTD changes:
- We must ignore error -ENOENT from parsers on subpartitions which is a
legitimate return value.
- PM support is added to the intel-dg driver.
Raw NAND changes:
- The major change in this MR will be the support for the Allwinner H616
NAND controller, which lead to numerous changes and cleanups in the
driver.
- Another notable change on this driver is the use of
field_get()/field_prep(), but since the global support for this
helpers is going to be merged in the same release as we start using
these helpers, it implies undefining them in the first place to avoid
warnings. Depending on the merging order (Yuri's bitmap branch or
mtd/next), a temporary warning may arise.
- Marvell drivers layout handling changes have also landed, they fix
previous definitions and abuses that have been made previously, which
implied to relax the ECC parameters validation in the core a bit.
- The Cadence NAND controller driver gets NV-DDR interface support.
SPI NAND changes:
- Support for FudanMicro FM25S01BI3 and ESMT F50L1G41LC is added.
SPI NOR changes:
- Fix SMPT parsing for S25FS-S flash family. They report variable dummy
cycles for reads. This results in the default of 0 being used. This
works for other Infineon chips, but not for the S25FS-S family. They
need 8 dummy cycles. Add fixup hooks to specify that. Also add fixup
hooks to fix incorrect map ID data in SFDP.
- Add support for a bunch of Winbond flashes. Their block protection
information is not discoverable, so they need to have an entry in the
flash tables to describe that.
- Some cleanups for Micron flash support.
- Add support for Micron mt35xu01gbba.
- Some SPI controllers like the Intel one on the PCI bus do not support
the read CR opcode (0x35). Do not use the opcode if the controller
does not support it.
Aside from these main changes, there is the usual load of API updates,
kdoc fixes, potential memory leaks fixes, etc.

sound updates for 6.19-rc1
The majority of changes at this time were about ASoC with a lot of
code refactoring works. From the functionality POV, there aren't much
to see, but we have a wide range of device-specific fixes and updates.
Here are some highlights:
- Continued ASoC API clean works, spanned over many files
- Added a SoundWire SCDA generic class driver with regmap support
- Enhancements and fixes for Cirrus, Intel, Maxim and Qualcomm.
- Support for ASoC Allwinner A523, Mediatek MT8189, Qualcomm QCM2290,
QRB2210 and SM6115, SpacemiT K1, and TI TAS2568, TAS5802, TAS5806,
TAS5815, TAS5828 and TAS5830
- Usual HD-audio and USB-audio quirks and fixups
- Support for Onkyo SE-300PCIE, TASCAM IF-FW/DM MkII
Some gpiolib changes for shared GPIOs are included along with this PR
for covering ASoC drivers changes.

Merge tag 'drm-next-2025-12-03' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie:
"There was a rather late merge of a new color pipeline feature, that
some userspace projects are blocked on, and has seen a lot of work in
amdgpu. This should have seen some time in -next. There is additional

* Minor cleanups and clarifications in ext4_map_blocks()
* Add documentation of the casefold and encrypt flags
* Add support for file systems with a blocksize greater than the pagesize
* Improve performance by enabling the caching the fact that an inode does
not have a Posix ACL.
Various Bug Fixes
* Fix false positive compliants from smatch
* Fix error code which is returned by ext4fs_dirhash() when Siphash is
used without the encryption key
* Fix races when writing to inline data files which could trigger a BUG

field to EXT4_IOC_SET_TUNE_SB_PARAM
* Fix a potential journal checksum failure whena file system is copied while
it is mounted read-only
* Fix a potential potential orphan file tracking error which only showed
on 32-bit systems
* Fix assertion checks in mballoc (which have to be explicitly enbled by
manually enabling AGGRESSIVE_CHECKS and recompiling)
* Avoid complaining about overly large orphan files created by mke2fs with
with file systems with a 64k block size

Pull hfs/hfsplus updates from Viacheslav Dubeyko:
"Several fixes for syzbot reported issues, HFS/HFS+ fixes of xfstests
failures, Kunit-based unit-tests introduction, and code cleanup:
- Dan Carpenter fixed a potential use-after-free issue in
hfs_correct_next_unused_CNID() method. Tetsuo Handa has made nice
fix of syzbot reported issue related to incorrect inode->i_mode
management if volume has been corrupted somehow. Yang Chenzhi has
made really good fix of potential race condition in
__hfs_bnode_create() method for HFS+ file system.
- Several fixes to xfstests failures. Particularly, generic/070,
generic/073, and generic/101 test-cases finish successfully for the
case of HFS+ file system right now.
- HFS and HFS+ drivers share multiple structures of on-disk layout
declarations. Some structures are used without any change. However,
we had two independent declarations of the same structures in HFS
and HFS+ drivers.
The on-disk layout declarations have been moved into
include/linux/hfs_common.h with the goal to exclude the
declarations duplication and to keep the HFS/HFS+ on-disk layout
declarations in one place.
Also, this patch prepares the basis for creating a hfslib that can
aggregate common functionality without necessity to duplicate the
same code in HFS and HFS+ drivers.
- HFS/HFS+ really need unit-tests because of multiple xfstests
failures. The first two patches introduce Kunit-based unit-tests
for the case string operations in HFS/HFS+ file system drivers"

Pull btrfs updates from David Sterba:
"Features:
- shutdown ioctl support (needs CONFIG_BTRFS_EXPERIMENTAL for now):
- set filesystem state as being shut down (also named going down
in other filesystems), where all active operations return EIO
and this cannot be changed until unmount
- pending operations are attempted to be finished but error
messages may still show up depending on where exactly the
shutdown happened
- scrub (and device replace) vs suspend/hibernate:
- a running scrub will prevent suspend, which can be annoying as
suspend is an immediate request and scrub is not critical
- filesystem freezing before suspend was not sufficient as the
problem was in process freezing
- behaviour change: on suspend scrub and device replace are
cancelled, where scrub can record the last state and continue
from there; the device replace has to be restarted from the
beginning
- zone stats exported in sysfs, from the perspective of the
filesystem this includes active, reclaimable, relocation etc zones
Performance:
- improvements when processing space reservation tickets by
optimizing locking and shrinking critical sections, cumulative
improvements in lockstat numbers show +15%
Notable fixes:
- use vmalloc fallback when allocating bios as high order allocations
can happen with wide checksums (like sha256)
- scrub will always track the last position of progress so it's not
starting from zero after an error
Core:
- under experimental config, checksum calculations are offloaded to
process context, simplifies locking and allows to remove
compression write worker kthread(s):
- speed improvement in direct IO throughput with buffered IO
fallback is +15% when not offloaded but this is more related to
internal crypto subsystem improvements
- this will be probably default in the future removing the sysfs
tunable
- (experimental) block size > page size updates:
- support more operations when not using large folios (encoded
read/write and send)
- raid56
- more preparations for fscrypt support
Other:
- more conversions to auto-cleaned variables
- parameter cleanups and removals
- extended warning fixes
- improved printing of structured values like keys
- lots of other cleanups and refactoring"

Networking changes for 6.19.
Core & protocols
----------------
- Replace busylock at the Tx queuing layer with a lockless list. Resulting
in a 300% (4x) improvement on heavy TX workloads, sending twice the
number of packets per second, for half the cpu cycles.
- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue. Normally we perform queue re-selection when flow comes out
of idle, but under extreme circumstances the flows may be constantly
busy. Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.
- Optimize the NAPI skb cache, make it larger, use it in more paths.
- Attempt returning Tx skbs to the originating CPU (like we already did
for Rx skbs).
- Various data structure layout and prefetch optimizations from Eric.
- Remove ktime_get() from the recvmsg() fast path, ktime_get() is sadly
quite expensive on recent AMD machines.
- Extend threaded NAPI polling to allow the kthread busy poll for packets.
- Make MPTCP use Rx backlog processing. This lowers the lock pressure,
improving the Rx performance.
- Support memcg accounting of MPTCP socket memory.
- Allow admin to opt sockets out of global protocol memory accounting
(using a sysctl or BPF-based policy). The global limits are a poor fit
for modern container workloads, where limits are imposed using cgroups.
- Improve heuristics for when to kick off AF_UNIX garbage collection.
- Allow users to control TCP SACK compression, and default to 33% of RTT.
- Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid unnecessarily
aggressive rcvbuf growth and overshot when the connection RTT is low.
- Preserve skb metadata space across skb_push / skb_pull operations.
- Support for IPIP encapsulation in the nftables flowtable offload.
- Support appending IP interface information to ICMP messages (RFC 5837).
- Support setting max record size in TLS (RFC 8449).
- Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL.
- Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock.
- Let users configure the number of write buffers in SMC.
- Add new struct sockaddr_unsized for sockaddr of unknown length,
from Kees.
- Some conversions away from the crypto_ahash API, from Eric Biggers.
- Some preparations for slimming down struct page.
- YAML Netlink protocol spec for WireGuard.
- Add a tool on top of YAML Netlink specs/lib for reporting commonly
computed derived statistics and summarized system state.
Driver API
----------
- Add CAN XL support to the CAN Netlink interface.
- Add uAPI for reporting PHY Mean Square Error (MSE) diagnostics,
as defined by the OPEN Alliance's "Advanced diagnostic features
for 100BASE-T1 automotive Ethernet PHYs" specification.
- Add DPLL phase-adjust-gran pin attribute (and implement it in zl3073x).
- Refactor xfrm_input lock to reduce contention when NIC offloads IPsec
and performs RSS.
- Add info to devlink params whether the current setting is the default
or a user override. Allow resetting back to default.
- Add standard device stats for PSP crypto offload.
- Leverage DSA frame broadcast to implement simple HSR frame duplication
for a lot of switches without dedicated HSR offload.
- Add uAPI defines for 1.6Tbps link modes.
Device drivers
--------------
- Add Motorcomm YT921x gigabit Ethernet switch support.
- Add MUCSE driver for N500/N210 1GbE NIC series.
- Convert drivers to support dedicated ops for timestamping control,
and away from the direct IOCTL handling. While at it support GET
operations for PHY timestamping.

Rust changes for v6.19
Toolchain and infrastructure:
- Add support for 'syn'.
Syn is a parsing library for parsing a stream of Rust tokens into a
syntax tree of Rust source code.
Currently this library is geared toward use in Rust procedural
macros, but contains some APIs that may be useful more generally.
'syn' allows us to greatly simplify writing complex macros such as
'pin-init' (Benno has already prepared the 'syn'-based version). We
will use it in the 'macros' crate too.
'syn' is the most downloaded Rust crate (according to crates.io), and
it is also used by the Rust compiler itself. While the amount of code
is substantial, there should not be many updates needed for these
crates, and even if there are, they should not be too big, e.g. +7k
-3k lines across the 3 crates in the last year.
'syn' requires two smaller dependencies: 'quote' and 'proc-macro2'.
I only modified their code to remove a third dependency
('unicode-ident') and to add the SPDX identifiers. The code can be
easily verified to exactly match upstream with the provided scripts.
They are all licensed under "Apache-2.0 OR MIT", like the other
vendored 'alloc' crate we had for a while.
Please see the merge commit with the cover letter for more context.
- Allow 'unreachable_pub' and 'clippy::disallowed_names' for doctests.
Examples (i.e. doctests) may want to do things like show public items
and use names such as 'foo'.
Nevertheless, we still try to keep examples as close to real code as
possible (this is part of why running Clippy on doctests is important
for us, e.g. for safety comments, which userspace Rust does not
support yet but we are stricter).
'kernel' crate:
- Replace our custom 'CStr' type with 'core::ffi::CStr'.
Using the standard library type reduces our custom code footprint,
and we retain needed custom functionality through an extension trait
and a new 'fmt!' macro which replaces the previous 'core' import.
This started in 6.17 and continued in 6.18, and we finally land the
replacement now. This required quite some stamina from Tamir, who
split the changes in steps to prepare for the flag day change here.
- Replace 'kernel::c_str!' with C string literals.
C string literals were added in Rust 1.77, which produce '&CStr's
(the 'core' one), so now we can write:
c"hi"
instead of:
c_str!("hi")
- Add 'num' module for numerical features.
It includes the 'Integer' trait, implemented for all primitive
integer types.
It also includes the 'Bounded' integer wrapping type: an integer
value that requires only the 'N' less significant bits of the wrapped
type to be encoded:
// An unsigned 8-bit integer, of which only the 4 LSBs are used.
let v = Bounded::<u8, 4>:🆕:<15>();
assert_eq!(v.get(), 15);
'Bounded' is useful to e.g. enforce guarantees when working with
bitfields that have an arbitrary number of bits.
Values can be constructed from simple non-constant expressions or,
for more complex ones, validated at runtime.
'Bounded' also comes with comparison and arithmetic operations (with
both their backing type and other 'Bounded's with a compatible
backing type), casts to change the backing type, extending/shrinking
and infallible/fallible conversions from/to primitives as applicable.
- 'rbtree' module: add immutable cursor ('Cursor').
It enables to use just an immutable tree reference where appropriate.
The existing fully-featured mutable cursor is renamed to 'CursorMut'.
kallsyms:
- Fix wrong "big" kernel symbol type read from procfs.
'pin-init' crate:
- A couple minor fixes (Benno asked me to pick these patches up for
him this cycle).
Documentation:
- Quick Start guide: add Debian 13 (Trixie).
Debian Stable is now able to build Linux, since Debian 13 (released
2025-08-09) packages Rust 1.85.0, which is recent enough.
We are planning to propose that the minimum supported Rust version in
Linux follows Debian Stable releases, with Debian 13 being the first
one we upgrade to, i.e. Rust 1.85.
MAINTAINERS:
- Add entry for the new 'num' module.
- Remove Alex as Rust maintainer: he hasn't had the time to contribute
for a few years now, so it is a no-op change in practice.
And a few other cleanups and improvements.

sched_ext: Changes for v6.19
- Improve recovery from misbehaving BPF schedulers. When a scheduler puts many tasks with varying affinity restrictions on a shared DSQ, CPUs scanning through tasks they cannot run can overwhelm the system, causing lockups. Bypass mode now uses per-CPU DSQs with a load balancer to avoid this, and hooks into the hardlockup detector to attempt recovery. Add scx_cpu0 example scheduler to demonstrate this scenario. - Add lockless peek operation for DSQs to reduce lock contention for schedulers that need to query queue state during load balancing. - Allow scx_bpf_reenqueue_local() to be called from anywhere in preparation for deprecating cpu_acquire/release() callbacks in favor of generic BPF hooks. - Prepare for hierarchical scheduler support: add scx_bpf_task_set_slice() and scx_bpf_task_set_dsq_vtime() kfuncs, make scx_bpf_dsq_insert*() return bool, and wrap kfunc args in structs for future aux__prog parameter. - Implement cgroup_set_idle() callback to notify BPF schedulers when a cgroup's idle state changes. - Fix migration tasks being incorrectly downgraded from stop_sched_class to rt_sched_class across sched_ext enable/disable. Applied late as the fix is low risk and the bug subtle but needs stable backporting. - Various fixes and cleanups including cgroup exit ordering, SCX_KICK_WAIT reliability, and backward compatibility improvements. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCaS4h1A4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGe/MAP9EZ0pLiTpmMtt6mI/11Fmi+aWfL84j1zt13cz9 W4vb4gEA9eVEH6n9xyC4nhcOk9AQwSDuCWMOzLsnhW8TbEHVTww= =8W/B -----END PGP SIGNATURE----- Merge tag 'sched_ext-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext Pull sched_ext updates from Tejun Heo: - Improve recovery from misbehaving BPF schedulers.

Merge tag 'printk-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
- Allow creaing nbcon console drivers with an unsafe write_atomic()
callback that can only be called by the final nbcon_atomic_flush_unsafe().
Otherwise, the driver would rely on the kthread.
It is going to be used as the-best-effort approach for an
experimental nbcon netconsole driver, see
https://lore.kernel.org/r/20251121-nbcon-v1-2-503d17b2b4af@debian.org
Note that a safe .write_atomic() callback is supposed to work in NMI
context. But some networking drivers are not safe even in IRQ
context:
https://lore.kernel.org/r/oc46gdpmmlly5o44obvmoatfqo5bhpgv7pabpvb6sjuqioymcg@gjsma3ghoz35
In an ideal world, all networking drivers would be fixed first and
the atomic flush would be blocked only in NMI context. But it brings
the question how reliable networking drivers are when the system is
in a bad state. They might block flushing more reliable serial
consoles which are more suitable for serious debugging anyway.
- Allow to use the last 4 bytes of the printk ring buffer.
- Prevent queuing IRQ work and block printk kthreads when consoles are
suspended. Otherwise, they create non-necessary churn or even block
the suspend.
- Release console_lock() between each record in the kthread used for
legacy consoles on RT. It might significantly speed up the boot.
- Release nbcon context between each record in the atomic flush. It
prevents stalls of the related printk kthread after it has lost the
ownership in the middle of a record
- Add support for NBCON consoles into KDB
- Add %ptsP modifier for printing struct timespec64 and use it where
possible
- Misc code clean up
