Scheduler changes for v7.0:
Scheduler Kconfig space updates:
- Further consolidate configurable preemption modes: reduce
the number of architectures that are allowed to offer
PREEMPT_NONE and PREEMPT_VOLUNTARY, reducing the number
of preemption models from four to just two: 'full' and 'lazy'
on up-to-date architectures (arm64, loongarch, powerpc,
riscv, s390, x86).
None and voluntary are only available as legacy features
on platforms that don't implement lazy preemption yet,
or which don't even support preemption.
The goal is to eventually remove cond_resched() and
voluntary preemption altogether.
(Peter Zijlstra)
RSEQ based 'scheduler time slice extension' support:
This allows a thread to request a time slice extension when it
enters a critical section to avoid contention on a resource when
the thread is scheduled out inside of the critical section.
- Add fields and constants for time slice extension
- Provide static branch for time slice extensions
- Add statistics for time slice extensions
- Add prctl() to enable time slice extensions
- Implement sys_rseq_slice_yield()
- Implement syscall entry work for time slice extensions
- Implement time slice extension enforcement timer
- Reset slice extension when scheduled
- Implement rseq_grant_slice_extension()
- entry: Hook up rseq time slice extension
- selftests: Implement time slice extension test
(Thomas Gleixner)
- Allow registering RSEQ with slice extension
- Move slice_ext_nsec to debugfs
- Lower default slice extension
- selftests/rseq: Add rseq slice histogram script
(Peter Zijlstra)
Scheduler performance/scalability improvements:
- Update rq->avg_idle when a task is moved to an idle CPU,
which improves the scalability of various workloads.
(Shubhang Kaushik)
- Reorder fields in 'struct rq' for better caching
(Blake Jones)
- Fair scheduler SMP NOHZ balancing code speedups:
- Move checking for nohz cpus after time check
- Change likelyhood of nohz.nr_cpus
- Remove nohz.nr_cpus and use weight of cpumask instead
(Shrikanth Hegde)
- Avoid false sharing for sched_clock_irqtime (Wangyang Guo)
- Drop useless cpumask_empty() in find_energy_efficient_cpu()
- Simplify task_numa_find_cpu()
- Use cpumask_weight_and() in sched_balance_find_dst_group()
(Yury Norov)
DL scheduler updates:
- Add a deadline server for sched_ext tasks (by Andrea Righi and
Joel Fernandes, with fixes by Peter Zijlstra)
RT scheduler updates:
- Skip currently executing CPU in rto_next_cpu() (Chen Jinghuang)
Entry code updates and performance improvements, which is part of the
scheduler tree in this cycle due to interdependencies with the RSEQ
based time slice extension work:
- Remove unused syscall argument from syscall_trace_enter()
- Rework syscall_exit_to_user_mode_work() for architecture reuse
- Add arch_ptrace_report_syscall_entry/exit()
- Inline syscall_exit_work() and syscall_trace_enter()
(Jinjie Ruan)
Scheduler core updates:
- Rework sched_class::wakeup_preempt() and rq_modified_*()
- Avoid rq->lock bouncing in sched_balance_newidle()
- Rename rcu_dereference_check_sched_domain() =>
rcu_dereference_sched_domain()
- <linux/compiler_types.h>: Add the __signed_scalar_typeof() helper
(Peter Zijlstra)
Fair scheduler updates/refactoring:
- Fold the sched_avg update
- Change rcu_dereference_check_sched_domain() to rcu-sched
- Switch to rcu_dereference_all()
- Remove superfluous rcu_read_lock()
- Limit hrtick work
(Peter Zijlstra)
- Join two #ifdef CONFIG_FAIR_GROUP_SCHED blocks
- Clean up comments in 'struct cfs_rq'
- Separate se->vlag from se->vprot
- Rename cfs_rq::avg_load to cfs_rq::sum_weight
- Rename cfs_rq::avg_vruntime to ::sum_w_vruntime & helper functions
- Introduce and use the vruntime_cmp() and vruntime_op() wrappers
for wrapped-signed aritmetics
- Sort out 'blocked_load*' namespace noise
(Ingo Molnar)
Scheduler debugging code updates:
- Export hidden tracepoints to modules (Gabriele Monaco)
- Convert copy_from_user() + kstrtouint() to kstrtouint_from_user()
(Fushuai Wang)
- Add assertions to QUEUE_CLASS (Peter Zijlstra)
- hrtimer: Fix tracing oddity (Thomas Gleixner)
Misc fixes and cleanups:
- Re-evaluate scheduling when migrating queued tasks out of
throttled cgroups (Zicheng Qu)
- Remove task_struct->faults_disabled_mapping (Christoph Hellwig)
- Fix math notation errors in avg_vruntime comment (Zhan Xusheng)
- sched/cpufreq: Use %pe format for PTR_ERR() printing (zenghongling)

A slightly calmer cycle for docs this time around, though there is still a
fair amount going on, including:
- Some signs of life on the long-moribund Japanese translation
- Documentation on policies around the use of generative tools for patch
submissions, and a separate document intended for consumption by
generative tools.
- The completion of the move of the documentation tools to tools/docs. For
now we're leaving a /scripts/kernel-doc symlink behind to avoid breaking
scripts.
- Ongoing build-system work includes the incorporation of documentation in
Python code, better support for documenting variables, and lots of
improvements and fixes.
- Automatic linking of man-page references -- cat(1), for example -- to
the online pages in the HTML build.
...and the usual array of typo fixes and such.

landlock: Add errata documentation section
Add errata section with code examples for querying errata and a warning that most applications should not check errata. Use kernel-doc directives to include errata descriptions from the header files instead of manual links. Also enhance existing DOC sections in security/landlock/errata/abi-*.h files with Impact sections, and update the code comment in syscalls.c to remind developers to update errata documentation when applicable. This addresses the gap where the kernel implements errata tracking but provides no user-facing documentation on how to use it, while improving the existing technical documentation in-place rather than duplicating it.

landlock: Add backwards compatibility for restrict flags
Add backwards compatibility handling for the restrict flags introduced in ABI version 7. This is shown as a separate code block (similar to the ruleset_attr handling in the switch statement) because restrict flags are passed to landlock_restrict_self() rather than being part of the ruleset attributes. Also fix misleading description of the /usr rule which incorrectly stated it "only allow[s] reading" when the code actually allows both reading and executing (LANDLOCK_ACCESS_FS_EXECUTE is included in allowed_access).

Documentation: Add documentation for VDUSE Address Space IDs
Address Space IDs allows the VDUSE framework to support devices able to expose different virtqueues to different part of the drivers. For example, to let QEMU handle the net device control virtqueue, so QEMU always knows the state of the device like mac address or number of queues enabled, while leaving the dataplane passthrough to the guest intact. This enables live migration. Expands the VDUSE documentation to explain how to use the new ioctls or the new struct members of old ioctls.

Documentation: use a source-read extension for the index link boilerplate
The root document usually has a special :ref:`genindex` link to the generated index. This is also the case for Documentation/index.rst. The other index.rst files deeper in the directory hierarchy usually don't. For SPHINXDIRS builds, the root document isn't Documentation/index.rst, but some other index.rst in the hierarchy. Currently they have a ".. only::" block to add the index link when doing SPHINXDIRS html builds. This is obviously very tedious and repetitive. The link is also added to all index.rst files in the hierarchy for SPHINXDIRS builds, not just the root document. Put the boilerplate in a sphinx-includes/subproject-index.rst file, and include it at the end of the root document for subproject builds in an ad-hoc source-read extension defined in conf.py. For now, keep having the boilerplate in translations, because this approach currently doesn't cover translated index link headers.

media: uapi: HEVC: Add v4l2_ctrl_hevc_ext_sps_[ls]t_rps controls
Some hardware (e.g.: Rockchip's rk3588 hevc decoder) need to fully parse the slice header, which cannot be passed with the current controls. There is also no skip method similar as to what can be found in verisilicon HW. The SPS is therefore extended through these 2 new controls, providing the long and short term reference information from the slice header for HEVC decoding. These now controls are similar as what is passed in the Vulkan Video API with the StdVideoH265ShortTermRefPicSet and StdVideoH265LongTermRefPicsSps structures embedded in the SPS struct.

Documentation/x86: Fix PR_SET_SPECULATION_CTRL error codes
If you force-disable mitigations on the kernel cmdline, for SPEC_STORE_BYPASS this ends up with the prctl returning -ENXIO, but contrary to the current docs for the other controls it returns -EPERM. Fix that. Note that this return value should probably be considered a bug. But, making the behaviour consistent with the current docs seems more likely to break existing users than help anyone out in practice, so just "fix" it by specifying it as correct. Since this is getting more wordy and confusing, also be more explicit about "control is not possible" be mentioning the boot configuration, to better distinguish this case conceptually from the FORCE_DISABLE failure mode.

This series introduces the Live Update Orchestrator, a kernel subsystem
designed to facilitate live kernel updates using a kexec-based reboot.
This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file
descriptors, which allows critical in-memory data, such as guest RAM or
any other large memory region, to be maintained in RAM across the kexec
reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- The 3 patch series "kexec: reorganize kexec and kdump sysfs" from
Sourabh Jain moves the kexec and kdump sysfs entries from /sys/kernel/
to /sys/kernel/kexec/ and adds back-compatibility symlinks which can
hopefully be removed one day.

Rapoport fixes a BUG which was being hit during KHO restoration of
vmalloc() regions.

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

This has been another busy cycle for documentation, with a lot of
build-system thrashing. That work should slow down from here on out.
- The various scripts and tools for documentation were spread out in
several directories; now they are (almost) all coalesced under
tools/docs/. The holdout is the kernel-doc script, which cannot be
easily moved without some further thought.
- As the amount of Python code increases, we are accumulating modules that
are imported by multiple programs. These modules have been pulled
together under tools/lib/python/ -- at least, for documentation-related
programs. There is other Python code in the tree that might eventually
want to move toward this organization.
- The Perl kernel-doc.pl script has been removed. It is no longer used by
default, and nobody has missed it, least of all anybody who actually had
to look at it.
- The docs build was controlled by a complex mess of makefilese that few
dared to touch. Mauro has moved that logic into a new program
(tools/docs/sphinx-build-wrapper) that, with any luck at all, will be far
easier to understand and maintain.
- The get_feat.pl program, used to access information under
Documentation/features/, has been rewritten in Python, bringing an end to
the use of Perl in the docs subsystem.
- The top-level README file has been reorganized into a more
reader-friendly presentation.
- A lot of Chinese translation additions
- Typo fixes and documentation updates as usual

liveupdate: luo_core: Live Update Orchestrator
Patch series "Live Update Orchestrator", v8. This series introduces the Live Update Orchestrator, a kernel subsystem designed to facilitate live kernel updates using a kexec-based reboot. This capability is critical for cloud environments, allowing hypervisors to be updated with minimal downtime for running virtual machines. LUO achieves this by preserving the state of selected resources, such as memory, devices and their dependencies, across the kernel transition. As a key feature, this series includes support for preserving memfd file descriptors, which allows critical in-memory data, such as guest RAM or any other large memory region, to be maintained in RAM across the kexec reboot. The other series that use LUO, are VFIO [1], IOMMU [2], and PCI [3] preservations. Github repo of this series [4]. The core of LUO is a framework for managing the lifecycle of preserved resources through a userspace-driven interface. Key features include: - Session Management Userspace agent (i.e. luod [5]) creates named sessions, each represented by a file descriptor (via centralized agent that controls /dev/liveupdate). The lifecycle of all preserved resources within a session is tied to this FD, ensuring automatic kernel cleanup if the controlling userspace agent crashes or exits unexpectedly. - File Preservation A handler-based framework allows specific file types (demonstrated here with memfd) to be preserved. Handlers manage the serialization, restoration, and lifecycle of their specific file types. - File-Lifecycle-Bound State A new mechanism for managing shared global state whose lifecycle is tied to the preservation of one or more files. This is crucial for subsystems like IOMMU or HugeTLB, where multiple file descriptors may depend on a single, shared underlying resource that must be preserved only once. - KHO Integration LUO drives the Kexec Handover framework programmatically to pass its serialized metadata to the next kernel. The LUO state is finalized and added to the kexec image just before the reboot is triggered. In the future this step will also be removed once stateless KHO is merged [6]. - Userspace Interface Control is provided via ioctl commands on /dev/liveupdate for creating and retrieving sessions, as well as on session file descriptors for managing individual files. - Testing The series includes a set of selftests, including userspace API validation, kexec-based lifecycle tests for various session and file scenarios, and a new in-kernel test module to validate the FLB logic. Introduce LUO, a mechanism intended to facilitate kernel updates while keeping designated devices operational across the transition (e.g., via kexec). The primary use case is updating hypervisors with minimal disruption to running virtual machines. For userspace side of hypervisor update we have copyless migration. LUO is for updating the kernel. This initial patch lays the groundwork for the LUO subsystem. Further functionality, including the implementation of state transition logic, integration with KHO, and hooks for subsystems and file descriptors, will be added in subsequent patches. Create a character device at /dev/liveupdate. A new uAPI header, <uapi/linux/liveupdate.h>, will define the necessary structures. The magic number for IOCTL is registered in Documentation/userspace-api/ioctl/ioctl-number.rst.

dma-buf: heaps: cma: Create CMA heap for each CMA reserved region
Aside from the main CMA region, it can be useful to allow userspace to
allocate from the other CMA reserved regions.
Indeed, those regions can have specific properties that can be useful to
a specific us-case.
For example, one of them platform I've been with has ECC enabled on the
entire memory but for a specific region. Using that region to allocate
framebuffers can be particular beneficial because enabling the ECC has a
performance and memory footprint cost.
Thus, exposing these regions as heaps user-space can allocate from and
import wherever needed allows to cover that use-case.
For now, only shared-dma-pools regions with the reusable property (ie,
backed by CMA) are supported, but eventually we'll want to support other
DMA pools types.
Since we collected all the CMA regions created during boot, we can
simply iterate over all of them to create the heaps.
This has a weird interaction with the recent work on the CMA name, in
particular the backward compatibility code created by commit

Since we're going to introduce multiple instances of the CMA heap driver, there's no single CMA heap anymore. Let's use the heap name instead to differentiate between all the heaps available in the system.

It has been a relatively busy cycle in docsland, with changes all over:
- Bring the kernel memory-model docs into the Sphinx build in the "literal
include" mode.
- Lots of build-infrastructure work, further cleaning up long-term
kernel-doc technical debt. The sphinx-pre-install tool has been
converted to Python and updated for current systems.
- A new tool to detect when documents have been moved and generate HTML
redirects; this can be used on kernel.org (or any other site hosting the
rendered docs) to avoid breaking links.
- Automated processing of the YAML files describing the netlink protocol.
- A significant update of the maintainer's PGP guide.
...and a seemingly endless series of typo fixes, build-problem fixes, etc.

Networking changes for 6.18.
Core & protocols
----------------
- Improve drop account scalability on NUMA hosts for RAW and UDP sockets
and the backlog, almost doubling the Pps capacity under DoS.
- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance by
an additional 50%, even more under extreme conditions.
- Add support for PSP encryption of TCP connections; this mechanism has
some similarities with IPsec and TLS, but offers superior HW offloads
capabilities.
- Ongoing work to support Accurate ECN for TCP. AccECN allows more than
one congestion notification signal per RTT and is a building block for
Low Latency, Low Loss, and Scalable Throughput (L4S).
- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath.
- Refactor skb deferral free to better scale on large multi-NUMA hosts,
this improves TCP and UDP RX performances significantly on such HW.
- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds.
- Improve handling of setups with a large number of nexthop, making dump
operating scaling linearly and avoiding unneeded synchronize_rcu() on
delete.
- Improve bridge handling of VLAN FDB, storing a single entry per bridge
instead of one entry per port; this makes the dump order of magnitude
faster on large switches.
- Restore IP ID correctly for encapsulated packets at GSO segmentation
time, allowing GRO to merge packets in more scenarios.
- Improve netfilter matching performance on large sets.
- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting recent
TCP autotuning changes.
- Allow bridges to redirect to a backup port when the bridge port is
administratively down.
- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups.
- Add RCU safety to dst->dev, closing a lot of possible races.
- A significant crypto library API for SCTP, MPTCP and IPv6 SR, reducing
code duplication.
- Supports pulling data from an skb frag into the linear area of an XDP
buffer.
Things we sprinkled into general kernel code
--------------------------------------------
- Generate netlink documentation from YAML using an integrated
YAML parser.
Driver API
----------
- Support using IPv6 Flow Label in Rx hash computation and RSS queue
selection.
- Introduce API for fetching the DMA device for a given queue, allowing
TCP zerocopy RX on more H/W setups.
- Make XDP helpers compatible with unreadable memory, allowing more
easily building DevMem-enabled drivers with a unified XDP/skbs
datapath.
- Add a new dedicated ethtool callback enabling drivers to provide the
number of RX rings directly, improving efficiency and clarity in RX
ring queries and RSS configuration.
- Introduce a burst period for the health reporter, allowing better
handling of multiple errors due to the same root cause.
- Support for DPLL phase offset exponential moving average, controlling
the average smoothing factor.
Device drivers
--------------
- Add a new Huawei driver for 3rd gen NIC (hinic3).
- Add a new SpacemiT driver for K1 ethernet MAC.
- Add a generic abstraction for shared memory communication devices
(dibps)
- Ethernet high-speed NICs:
- nVidia/Mellanox:
- Use multiple per-queue doorbell, to avoid MMIO contention issues

powerpc/pseries: Define papr-hvpipe ioctl
PowerPC FW introduced HVPIPE RTAS calls such as ibm,send-hvpipe-msg and ibm,receive-hvpipe-msg for the user space to exchange information with different sources such as Hardware Management Consoles (HMC). HVPIPE_IOC_CREATE_HANDLE is defined to use /dev/papr-hvpipe interface for ibm,send-hvpipe-msg and ibm,receive-hvpipe-msg RTAS calls. Also defined papr_hvpipe_hdr which will added in the payload that is passed between the kernel and the user space.

- IOMMU HW now has features to directly assign HW command queues to a
guest VM. In this mode the command queue operates on a limited set of
invalidation commands that are suitable for improving guest invalidation
performance and easy for the HW to virtualize.
This PR brings the generic infrastructure to allow IOMMU drivers to
expose such command queues through the iommufd uAPI, mmap the doorbell
pages, and get the guest physical range for the command queue ring
itself.
- An implementation for the NVIDIA SMMUv3 extension "cmdqv" is built on
the new iommufd command queue features. It works with the existing SMMU
driver support for cmdqv in guest VMs.
- Many precursor cleanups and improvements to support the above cleanly,
changes to the general ioctl and object helpers, driver support for
VDEVICE, and mmap pgoff cookie infrastructure.
- Sequence VDEVICE destruction to always happen before VFIO device
destruction. When using the above type features, and also in future
confidential compute, the internal virtual device representation becomes
linked to HW or CC TSM configuration and objects. If a VFIO device is
removed from iommufd those HW objects should also be cleaned up to
prevent a sort of UAF. This became important now that we have HW backing
the VDEVICE.

"This broadly brings the assigned HW command queue support to iommufd.
This feature is used to improve SVA performance in VMs by avoiding
paravirtualization traps during SVA invalidations.
Along the way I think some of the core logic is in a much better state
to support future driver backed features.

It has been a relatively busy cycle for docs, especially the build system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the turn of
the millennium. Over the following 25 years, it accumulated a vast
amount of cruft, all in a language few people want to deal with anymore.
Mauro's Python replacement in 6.16 faithfully reproduced all of the cruft
in the hope of avoiding regressions. Now that we have a more reasonable
code base, though, we can work on cleaning it up; many of the changes
this time around are toward that end.
- A reorganization of the ext4 docs into the usual TOC format.
- Various Chinese translations and updates.
- A new script from Mauro to help with docs-build testing.
- A new document for linked lists
- A sweep through MAINTAINERS fixing broken GitHub git:// repository links.
...and lots of fixes and updates.

Merge tag 'docs-6.17' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"It has been a relatively busy cycle for docs, especially the build
system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the
turn of the millennium. Over the following 25 years, it accumulated
a vast amount of cruft, all in a language few people want to deal
with anymore. Mauro's Python replacement in 6.16 faithfully
reproduced all of the cruft in the hope of avoiding regressions.
Now that we have a more reasonable code base, though, we can work
on cleaning it up; many of the changes this time around are toward
that end.
- A reorganization of the ext4 docs into the usual TOC format.
- Various Chinese translations and updates.
- A new script from Mauro to help with docs-build testing.
- A new document for linked lists
- A sweep through MAINTAINERS fixing broken GitHub git:// repository
links.
...and lots of fixes and updates"

media: uvcvideo: Introduce V4L2_META_FMT_UVC_MSXU_1_5
The UVC driver provides two metadata types V4L2_META_FMT_UVC, and V4L2_META_FMT_D4XX. The only difference between the two of them is that V4L2_META_FMT_UVC only copies PTS, SCR, size and flags, and V4L2_META_FMT_D4XX copies the whole metadata section. Now we only enable V4L2_META_FMT_D4XX for the Intel D4xx family of devices, but it is useful to have the whole metadata payload for any device where vendors include other metadata, such as the one described by Microsoft: https://learn.microsoft.com/en-us/windows-hardware/drivers/stream/mf-capture-metadata This patch introduces a new format V4L2_META_FMT_UVC_MSXU_1_5, that is identical to V4L2_META_FMT_D4XX. Let the user enable this format with a quirk for now. This way they can test if their devices provide useful metadata without rebuilding the kernel. They can later contribute patches to auto-quirk their devices. We will also work in methods to auto-detect devices compatible with this new metadata format.

dma-buf: heaps: Give default CMA heap a fixed name
The CMA heap's name in devtmpfs can vary depending on how the heap is defined. Its name defaults to "reserved", but if a CMA area is defined in the devicetree, the heap takes on the devicetree node's name, such as "default-pool" or "linux,cma". To simplify naming, unconditionally name it "default_cma_region", but keep a legacy node in place backed by the same underlying allocator for backwards compatibility.

block: remove pktcdvd driver
This driver has long outlived it's utility, and it's broken and unloved. The main use case for this was direct mount with UDF of cd-rw drives that required 32kb packets. It would collect writes into that size and write them out in multiples of that. That's not a common use case anymore, the world has moved on from those kinds of media. To make matters worse, it's actively breaking setups where it's not even required or useful.
