ISP is a child device to GFX, and its device specific information
is not available in ACPI. Adding the 2 GPIO resources required for
ISP_v4_1_1 in amdgpu_isp driver.
- GPIO 0 to allow sensor driver to enable and disable sensor module.
- GPIO 85 to allow ISP driver to enable and disable ISP RGB streaming mode.

Currently retry and general validity of msg_inq is gated on it being
larger than zero, but it's entirely possible for this to be slightly
inaccurate. In particular, if FIN is received, it'll return 1.
Just use larger than 1 as the check. This covers both the FIN case, and
at the same time, it doesn't make much sense to retry a recv immediately
if there's even just a single 1 byte of valid data in the socket.
Leave the SOCK_NONEMPTY flagging when larger than 0 still, as an app may
use that for the final receive.

Pull nfsd updates from Chuck Lever:
"The marquee feature for this release is that the limit on the maximum
rsize and wsize has been raised to 4MB. The default remains at 1MB,
but risk-seeking administrators now have the ability to try larger I/O
sizes with NFS clients that support them. Eventually the default
setting will be increased when we have confidence that this change
will not have negative impact.
With v6.16, NFSD now has its own debugfs file system where we can add
experimental features and make them available outside of our
development community without impacting production deployments. The
first experimental setting added is one that makes all NFS READ
operations use vfs_iter_read() instead of the NFSD splice actor. The
plan is to eventually retire the splice actor, as that will enable a
number of new capabilities such as the use of struct bio_vec from the
top to the bottom of the NFSD stack.
Jeff Layton contributed a number of observability improvements. The
use of dprintk() in a number of high-traffic code paths has been
replaced with static trace points.
This release sees the continuation of efforts to harden the NFSv4.2
COPY operation. Soon, the restriction on async COPY operations can be
lifted.
Many thanks to the contributors, reviewers, testers, and bug reporters
who participated during the v6.16 development cycle"

The syscalls that were consistently observed were set_robust_list and
rseq. This is because perf cannot find their child process.
This change ensures that the return value is always printed.
Before:
0.256 ( 0.001 ms): set_robust_list(head: 0x7f09c77dba20, len: 24) =
0.259 ( 0.001 ms): rseq(rseq: 0x7f09c77dc0e0, rseq_len: 32, sig: 1392848979) =
After:
0.270 ( 0.002 ms): set_robust_list(head: 0x7f0bb14a6a20, len: 24) = 0
0.273 ( 0.002 ms): rseq(rseq: 0x7f0bb14a70e0, rseq_len: 32, sig: 1392848979) = 0
Committer notes:
As discussed in the thread in the Link: tag below, these two don't
return a pid, but for syscalls returning one, we need to print the
result and if we manage to find the children in 'perf trace' data
structures, then print its name as well.

Let's convert it to use absolute percent value so that it can add up to
the overhead for that entry.

Avoid casting the input pointer to `*const _`, allowing the output
pointer to be `*mut` if the input is `*mut`. This allows a number of
`*const` to `*mut` conversions to be removed at the cost of slightly
worse ergonomics when the macro is used with a reference rather than a
pointer; the only example of this was in the macro's own doctest.

Pull drm updates from Dave Airlie:
"As part of building up nova-core/nova-drm pieces we've brought in some
rust abstractions through this tree, aux bus being the main one, with
devres changes also in the driver-core tree. Along with the drm core
abstractions and enough nova-core/nova-drm to use them. This is still
all stub work under construction, to build the nova driver upstream.
The other big NVIDIA related one is nouveau adds support for
Hopper/Blackwell GPUs, this required a new GSP firmware update to
570.144, and a bunch of rework in order to support multiple fw

The root cause is after commit 84b5bb8bf0f6 ("f2fs: modify
f2fs_is_checkpoint_ready logic to allow more data to be written with the
CP disable"), we will get chance to allow f2fs_is_checkpoint_ready() to
return true once below conditions are all true:
1. checkpoint is disabled
2. there are not enough free segments
3. there are enough free blocks
Then it will cause f2fs_balance_fs() to trigger foreground GC.
void f2fs_balance_fs(struct f2fs_sb_info *sbi, bool need)
...
if (!f2fs_is_checkpoint_ready(sbi))
return;
And the testcase mounts f2fs image w/ gc_merge,checkpoint=disable, so deadloop
will happen through below race condition:
- f2fs_do_shutdown - vfs_fallocate - gc_thread_func
- file_start_write
- __sb_start_write(SB_FREEZE_WRITE)
- f2fs_fallocate
- f2fs_expand_inode_data
- f2fs_map_blocks
- f2fs_balance_fs
- prepare_to_wait
- wake_up(gc_wait_queue_head)
- io_schedule
- bdev_freeze
- freeze_super
- sb->s_writers.frozen = SB_FREEZE_WRITE;
- sb_wait_write(sb, SB_FREEZE_WRITE);
- if (sbi->sb->s_writers.frozen >= SB_FREEZE_WRITE) continue;
: cause deadloop
This patch fix to add check condition in f2fs_balance_fs(), so that if
checkpoint is disabled, we will just skip trigger foreground GC to
avoid such deadloop issue.
Meanwhile let's remove f2fs_is_checkpoint_ready() check condition in
f2fs_balance_fs(), since it's redundant, due to the main logic in the
function is to check:
a) whether checkpoint is disabled
b) there is enough free segments
f2fs_balance_fs() still has all logics after f2fs_is_checkpoint_ready()'s
removal.

when performing buffered writes in a large section,
overhead is incurred due to the iteration through
ckpt_valid_blocks within the section.
when SEGS_PER_SEC is 128, this overhead accounts for 20% within
the f2fs_write_single_data_page routine.
as the size of the section increases, the overhead also grows.
to handle this problem ckpt_valid_blocks is
added within the section entries.

Refactor some gmap functions; move the implementation into a separate
file with only helper functions. The new helper functions work on vm
addresses, leaving all gmap logic in the gmap functions, which mostly
become just wrappers.
The whole gmap handling is going to be moved inside KVM soon, but the
helper functions need to touch core mm functions, and thus need to
stay in the core of kernel.

Currently, starting a PV VM on an iomap-based filesystem with large
folio support, such as XFS, will not work. We'll be stuck in
unpack_one()->gmap_make_secure(), because we can't seem to make progress
splitting the large folio.
The problem is that we require a writable PTE but a writable PTE under such
filesystems will imply a dirty folio.
So whenever we have a writable PTE, we'll have a dirty folio, and dirty
iomap folios cannot currently get split, because
split_folio()->split_huge_page_to_list_to_order()->filemap_release_folio()
will fail in iomap_release_folio().
So we will not make any progress splitting such large folios.
Until dirty folios can be split more reliably, let's manually trigger
writeback of the problematic folio using
filemap_write_and_wait_range(), and retry the split immediately
afterwards exactly once, before looking up the folio again.
Should this logic be part of split_folio()? Likely not; most split users
don't have to split so eagerly to make any progress.
For now, this seems to affect xfs, zonefs and erofs, and this patch
makes it work again (tested on xfs only).
While this could be considered a fix for commit 6795801366da ("xfs: Support
large folios"), commit df2f9708ff1f ("zonefs: enable support for large
folios") and commit ce529cc25b18 ("erofs: enable large folios for iomap
mode"), before commit eef88fe45ac9 ("s390/uv: Split large folios in
gmap_make_secure()"), we did not try splitting large folios at all. So it's
all rather part of making SE compatible with file systems that support
large folios. But to have some "Fixes:" tag, let's just use eef88fe45ac9.
Not CCing stable, because there are a lot of dependencies, and it simply
not working is not critical in stable kernels.

Pull audit updates from Paul Moore:
- Always record AUDIT_ANOM events when auditing is enabled.
Prior to this patch we only recorded AUDIT_ANOM events if auditing
was enabled and the admin/distro had explicitly configured audit
beyond the defaults. Considering that AUDIT_ANOM events are anomolous
events considered to be "security relevant", it seems wise to record
these events as long as auditing is enabled, even if the system is
running with a default audit configuration.
- Mark the audit_log_vformat() function with the __printf() attribute
to quiet GCC.

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux updates from Paul Moore:
- Reduce the SELinux impact on path walks.
Add a small directory access cache to the per-task SELinux state.
This cache allows SELinux to cache the most recently used directory
access decisions in order to avoid repeatedly querying the AVC on
path walks where the majority of the directories have similar
security contexts/labels.
My performance measurements are crude, but prior to this patch the
time spent in SELinux code on a 'make allmodconfig' run was 103% that
of __d_lookup_rcu(), and with this patch the time spent in SELinux
code dropped to 63% of __d_lookup_rcu(), a ~40% improvement.
Additional improvments can be expected in the future, but those will
require additional SELinux policy/toolchain support.
- Add support for wildcards in genfscon policy statements.
This patch allows for wildcards in the genfscon patch matching logic
as opposed to the prefix matching that was used prior to this change.
Adding wilcard support allows for more expressive and efficient path
matching in the policy which is especially helpful for sysfs, and has
resulted in a ~15% boot time reduction in Android.
SELinux policies can opt into wilcard matching by using the
"genfs_seclabel_wildcard" policy capability.
- Unify the error/OOM handling of the SELinux network caches.
A failure to allocate memory for the SELinux network caches isn't
fatal as the object label can still be safely returned to the caller,
it simply means that we cannot add the new data to the cache, at
least temporarily. This patch corrects this behavior for the
InfiniBand cache and does some minor cleanup.
- Minor improvements around constification, 'likely' annotations, and
removal of bogus comments.

Any delay between the "kexec load" and "kexec exec" exacerbated the

- Any file measurements post "kexec load" were not carried across
kexec, resulting in the measurement list being out of sync with the

Create KUnit tests to test the conversion between YUV and RGB. Test each
conversion and range combination with some common colors.
The code used to compute the expected result can be found in comment.
[Louis Chauvet:
- fix minor formating issues (whitespace, double line)
- change expected alpha from 0x0000 to 0xffff
- adapt to the new get_conversion_matrix usage
- apply the changes from Arthur
- move struct pixel_yuv_u8 to the test itself]

The functions drm_get_color_encoding_name and drm_get_color_range_name
are useful for clarifying test results. Therefore, export them so they
can be used in tests built as modules.
