During non-transmitted (nontx) profile configuration, interface
index of the transmitted (tx) profile is used to retrieve the
wireless device (wdev) associated with it. With MLO, this 'wdev'
may be part of an MLD with more than one link, hence only
interface index is not sufficient anymore to retrieve the correct
tx profile. Add a new attribute to configure link id of tx profile.

Add queue id support to the user queue wait IOCTL
drm_amdgpu_userq_wait structure.
This is required to retrieve the wait user queue and maintain
the fence driver references in it so that the user queue in
the same context releases their reference to the fence drivers
at some point before queue destruction.
Otherwise, we would gather those references until we
don't have any more space left and crash.

Currently ublk only allows the size of the ublkb block device to be
set via UBLK_CMD_SET_PARAMS before UBLK_CMD_START_DEV is triggered.
This does not provide support for extendable user-space block devices
without having to stop and restart the underlying ublkb block device
causing IO interruption.
This patch adds a new ublk command UBLK_U_CMD_UPDATE_SIZE to allow the
ublk block device to be resized on-the-fly.
Feature flag UBLK_F_UPDATE_SIZE is also added to indicate support.

This works just like pipe2(2), except it also supports fixed file
descriptors. Used in a similar fashion as for other fd instantiating
opcodes (like accept, socket, open, etc), where sqe->file_slot is set
appropriately if two direct descriptors are desired rather than a set
of normal file descriptors.
sqe->addr must be set to a pointer to an array of 2 integers, which
is where the fixed/normal file descriptors are copied to.
sqe->pipe_flags contains flags, same as what is allowed for pipe2(2).
Future expansion of per-op private flags can go in sqe->ioprio,
like we do for other opcodes that take both a "syscall" flag set and
an io_uring opcode specific flag set.

Pull io_uring fixes from Jens Axboe:
- Correctly cap iov_iter->nr_segs for imports of registered buffers,
both kbuf and normal ones.
Three cleanups to make it saner first, then two fixes for each of the
buffer types.
This fixes a performance regression where partial buffer usage
doesn't trim the tail number of segments, leading the block layer to
iterate the IOs to check if it needs splitting.
- Two patches tweaking the newly introduced zero-copy rx API, mostly to
keep the API consistent once we add multiple interface queues per
ring support in the 6.16 release.

fib_rule, ip6_tunnel, and a whole lot of if_* headers lack the customary
_UAPI in the header guard. Without it YNL build can't protect from in tree
and system headers both getting included. YNL doesn't need most of these
but it's annoying to have to fix them one by one.
Note that header installation strips this _UAPI prefix so this should
result in no change to the end user.

IORING_OP_RECV_ZC requests take a zcrx object id via sqe::zcrx_ifq_idx,
which binds it to the corresponding if / queue. However, we don't return
that id back to the user. It's fine as currently there can be only one
zcrx and the user assumes that its id should be 0, but as we'll need
multiple zcrx objects in the future let's explicitly pass it back on

Currently userspace is able to notify the kernel to invalidate the cache
for an inode. This means that, if all the inodes in a filesystem need to
be invalidated, then userspace needs to iterate through all of them and do
this kernel notification separately.
This patch adds the concept of 'epoch': each fuse connection will have the
current epoch initialized and every new dentry will have it's d_time set to
the current epoch value. A new operation will then allow userspace to
increment the epoch value. Every time a dentry is d_revalidate()'ed, it's
epoch is compared with the current connection epoch and invalidated if it's
value is different.

Allow the app to request that CHALLENGEs be passed to it through an
out-of-band queue that allows recvmsg() to pick it up so that the app can
add data to it with sendmsg().
This will allow the application (AFS or userspace) to interact with the
process if it wants to and put values into user-defined fields. This will
be used by AFS when talking to a fileserver to supply that fileserver with
a crypto key by which callback RPCs can be encrypted (ie. notifications
from the fileserver to the client).

Fix the frequency returned to the user space by
the DRM_IVPU_PARAM_CORE_CLOCK_RATE GET_PARAM IOCTL.
The kernel driver returned CPU frequency for MTL and bare
PLL frequency for LNL - this was inconsistent and incorrect
for both platforms. With this fix the driver returns maximum
frequency of the NPU data processing unit (DPU) for all HW
generations. This is what user space always expected.
Also do not set CPU frequency in boot params - the firmware
does not use frequency passed from the driver, it was only
used by the early pre-production firmware.
With that we can remove CPU frequency calculation code.
Show NPU frequency in FREQ_CHANGE interrupt when frequency
tracking is enabled.

If you modify for example the UDP ports and pass BPF_F_PSEUDO_HDR,

Add support for hardware-wrapped keys to fscrypt. Such keys are
protected from certain attacks, such as cold boot attacks. For more
information, see the "Hardware-wrapped keys" section of
Documentation/block/inline-encryption.rst.
To support hardware-wrapped keys in fscrypt, we allow the fscrypt master
keys to be hardware-wrapped. File contents encryption is done by
passing the wrapped key to the inline encryption hardware via
blk-crypto. Other fscrypt operations such as filenames encryption
continue to be done by the kernel, using the "software secret" which the
hardware derives. For more information, see the documentation which
this patch adds to Documentation/filesystems/fscrypt.rst.
Note that this feature doesn't require any filesystem-specific changes.
However it does depend on inline encryption support, and thus currently
it is only applicable to ext4 and f2fs.
The version of this feature introduced by this patch is mostly
equivalent to the version that has existed downstream in the Android
Common Kernels since 2020. However, a couple fixes are included.
First, the flags field in struct fscrypt_add_key_arg is now placed in
the proper location. Second, key identifiers for HW-wrapped keys are
now derived using a distinct HKDF context byte; this fixes a bug where a
raw key could have the same identifier as a HW-wrapped key. Note that
as a result of these fixes, the version of this feature introduced by
this patch is not UAPI or on-disk format compatible with the version in
the Android Common Kernels, though the divergence is limited to just
those specific fixes. This version should be used going forwards.
This patch has been heavily rewritten from the original version by
Gaurav Kashyap <quic_gaurkash@quicinc.com> and
Barani Muthukumaran <bmuthuku@codeaurora.org>.

This adds the UAPI for the Asahi driver targeting the GPU in the Apple
M1 and M2 series systems on chip. The UAPI design is based on other
modern Vulkan-capable drivers, including Xe and Panthor. Memory
management is based on explicit VM management. Synchronization is
exclusively explicit sync.
This UAPI is validated against our open source Mesa stack, which is
fully conformant to the OpenGL 4.6, OpenGL ES 3.2, OpenCL 3.0, and
Vulkan 1.4 standards. The Vulkan driver supports sparse, exercising the
VM_BIND mechanism.
This patch adds the standalone UAPI header. It is implemented by an open
source DRM driver written in Rust. We fully intend to upstream this
driver when possible. However, as a production graphics driver, it
depends on a significant number of Rust abstractions that will take a
long time to upstream. In the mean time, our userspace is upstream in
Mesa but is not allowed to probe with upstream Mesa as the UAPI is not
yet reviewed and merged in the upstream kernel. Although we ship a
patched Mesa in Fedora Asahi Remix, any containers shipping upstream
Mesa builds are broken for our users, including upstream Flatpak and
Waydroid runtimes. Additionally, it forces us to maintain forks of Mesa
and virglrenderer, which complicates bisects.
The intention in sending out this patch is for this UAPI to be
thoroughly reviewed. Once we as the DRM community are satisfied with the
UAPI, this header lands signifying that the UAPI is stable and must only
be evolved in backwards-compatible ways; it will be the UAPI implemented
in the DRM driver that eventually lands upstream. That promise lets us
enable upstream Mesa, solving all these issues while the upstream Rust
abstractions are developed.
https://github.com/alyssarosenzweig/linux/commits/agx-uapi-v7 contains
the DRM driver implementing this proposed UAPI.
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33984 contains
the Mesa patches to implement this proposed UAPI.
That Linux and Mesa branch together give a complete graphics/compute
stack on top of this UAPI.

This patch updates the VM_IOCTL to allow userspace to synchronize
the mapping/unmapping of a BO in the page table.
The major changes are:
- it adds a drm_timeline object as an input parameter to the VM IOCTL.
- this object is used by the kernel to sync the update of the BO in
the page table during the mapping of the object.
- the kernel also synchronizes the tlb flush of the page table entry of
this object during the unmapping (Added in this series:
https://patchwork.freedesktop.org/series/131276/ and
https://patchwork.freedesktop.org/patch/584182/)
- the userspace can wait on this timeline, and then the BO is ready to
be consumed by the GPU.
The UAPI for the same has been approved here:
https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/392
V2:
- remove the eviction fence coupling
V3:
