drm/amd/display: Optimize cursor position updates
[why] Updating the cursor enablement register can be a slow operation and accumulates when high polling rate cursors cause frequent updates asynchronously to the cursor position.

This removes the read-modify-write from the cursor position programming path in HUBP and DPP, leaving only the register writes.

drm/amd/display: Add hubp cache reset when powergating
[Why] When HUBP is power gated, the SW state can get out of sync with the hardware state causing cursor to not be programmed correctly. [How] Similar to DPP, add a HUBP reset function which is called wherever HUBP is initialized or powergated. This function will clear the cursor position and attribute cache allowing for proper programming when the HUBP is brought back up.

drm/amd/amdgpu: Prevent null pointer dereference in GPU bandwidth calculation
If the parent is NULL, adev->pdev is used to retrieve the PCIe speed and
width, ensuring that the function can still determine these
capabilities from the device itself.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:6193 amdgpu_device_gpu_bandwidth()
error: we previously assumed 'parent' could be null (see line 6180)

drm/amd/display: Fix error pointers in amdgpu_dm_crtc_mem_type_changed
The function amdgpu_dm_crtc_mem_type_changed was dereferencing pointers
returned by drm_atomic_get_plane_state without checking for errors. This
could lead to undefined behavior if the function returns an error pointer.
This commit adds checks using IS_ERR to ensure that new_plane_state and
old_plane_state are valid before dereferencing them.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:11486 amdgpu_dm_crtc_mem_type_changed()
error: 'new_plane_state' dereferencing possible ERR_PTR()

"Intel Trust Domain updates.
The existing TDX code needs a _bit_ of metadata from the TDX module.
But KVM is going to need a bunch more very shortly. Rework the
interface with the TDX module to be more consistent and handle the new
higher volume.
The TDX module has added a few new features. The first is a promise
not to clobber RBP under any circumstances. Basically the kernel now
will refuse to use any modules that don't have this promise. Second,
enable the new "REDUCE_VE" feature. This ensures that the TDX module
will not send some silly virtualization exceptions that the guest had
no good way to handle anyway.

x86/boot changes for v6.14:
- A large and involved preparatory series to pave the way to add exception
handling for relocate_kernel - which will be a debugging facility that
has aided in the field to debug an exceptionally hard to debug early boot bug.
Plus assorted cleanups and fixes that were discovered along the way,
by David Woodhouse:
- Clean up and document register use in relocate_kernel_64.S
- Use named labels in swap_pages in relocate_kernel_64.S
- Only swap pages for ::preserve_context mode
- Allocate PGD for x86_64 transition page tables separately
- Copy control page into place in machine_kexec_prepare()
- Invoke copy of relocate_kernel() instead of the original
- Move relocate_kernel to kernel .data section
- Add data section to relocate_kernel
- Drop page_list argument from relocate_kernel()
- Eliminate writes through kernel mapping of relocate_kernel page
- Clean up register usage in relocate_kernel()
- Mark relocate_kernel page as ROX instead of RWX
- Disable global pages before writing to control page
- Ensure preserve_context flag is set on return to kernel
- Use correct swap page in swap_pages function
- Fix stack and handling of re-entry point for ::preserve_context
- Mark machine_kexec() with __nocfi
- Cope with relocate_kernel() not being at the start of the page
- Use typedef for relocate_kernel_fn function prototype
- Fix location of relocate_kernel with -ffunction-sections (fix by Nathan Chancellor)
- A series to remove the last remaining absolute symbol references from
.head.text, and enforce this at build time, by Ard Biesheuvel:
- Avoid WARN()s and panic()s in early boot code
- Don't hang but terminate on failure to remap SVSM CA
- Determine VA/PA offset before entering C code
- Avoid intentional absolute symbol references in .head.text
- Disable UBSAN in early boot code
- Move ENTRY_TEXT to the start of the image
- Move .head.text into its own output section
- Reject absolute references in .head.text
- Which build-time enforcement uncovered a handful of bugs of essentially
non-working code, and a wrokaround for a toolchain bug, fixed by
Ard Biesheuvel as well:
- Fix spurious undefined reference when CONFIG_X86_5LEVEL=n, on GCC-12
- Disable UBSAN on SEV code that may execute very early
- Disable ftrace branch profiling in SEV startup code
- And miscellaneous cleanups:
- kexec_core: Add and update comments regarding the KEXEC_JUMP flow (Rafael J. Wysocki)
- x86/sysfs: Constify 'struct bin_attribute' (Thomas Weißschuh)

perf-tools changes for v6.14
There are a lot of changes in the perf tools in this cycle.
build
-----
* Use generic syscall table to generate syscall numbers on supported archs.
* This also enables to get rid of libaudit which was used for syscall numbers.
* Remove python2 support as it's deprecated for years.
* Fix issues on static build with libzstd.
perf record
-----------
* Intel-PT supports "aux-action" config term to pause or resume tracing in
the aux-buffer. Users can start the intel_pt event as "started-paused" and
configure other events to control the Intel-PT tracing.
# perf record --kcore -e intel_pt/aux-action=start-paused/ \
-e syscalls:sys_enter_newuname/aux-action=resume/ \
-e syscalls:sys_exit_newuname/aux-action=pause/ -- uname
This requires the kernel support (which was added in v6.13).
perf lock
---------
* 'perf lock contention' command has an ability to symbolize locks in
dynamically allocated objects using slab cache name when it runs with BPF.
Those dynamic locks would have "&" prefix in the name to distinguish them
from ordinary (static) locks.
# perf lock con -abl -E 5 sleep 1
contended total wait max wait avg wait address symbol
2 1.95 us 1.77 us 975 ns ffff9d5e852d3498 &task_struct (mutex)
1 1.18 us 1.18 us 1.18 us ffff9d5e852d3538 &task_struct (mutex)
4 1.12 us 354 ns 279 ns ffff9d5e841ca800 &kmalloc-cg-512 (mutex)
2 859 ns 617 ns 429 ns ffffffffa41c3620 delayed_uprobe_lock (mutex)
3 691 ns 388 ns 230 ns ffffffffa41c0940 pack_mutex (mutex)
This also requires the kernel/BPF support (which was added in v6.13).
perf ftrace
-----------
* 'perf ftrace latency' command gets a couple of options to support linear
buckets instead of exponential. Also it's possible to specify max and
min latency for the linear buckets.
# perf ftrace latency -abn -T switch_mm_irqs_off --bucket-range=100 \
--min-latency=200 --max-latency=800 -- sleep 1
# DURATION | COUNT | GRAPH |

# statistics (in nsec)
total time: 2162212
avg time: 967
max time: 16817
min time: 132
count: 2236
* As you can see in the above example, it nows shows the statistics at the
end so that users can see the avg/max/min latencies easily.
* 'perf ftrace profile' command has --graph-opts option like 'perf ftrace
trace' so that it can control the tracing behaviors in the same way.
For example, it can limit the function call depth or threshold.
perf script
-----------
* Improve physical memory resolution in 'mem-phys-addr' script by parsing
/proc/iomem file.
# perf script mem-phys-addr -- find /
...

Others
------
* 'perf test' gets --runs-per-test option to run the test cases repeatedly.
This would be helpful to see if it's flaky.
* Add 'parse_events' method to Python perf extension module, so that users
can use the same event parsing logic in the python code. One more step
towards implementing perf tools in Python. :)
* Support opening tracepoint events without libtraceevent. This will be
helpful if it won't use the tracing data like in 'perf stat'.
* Update ARM Neoverse N2/V2 JSON events and metrics

xfs: don't call remap_verify_area with sb write protection held
The XFS_IOC_EXCHANGE_RANGE ioctl with the XFS_EXCHANGE_RANGE_TO_EOF flag
operates on a range bounded by the end of the file. This means the
actual amount of blocks exchanged is derived from the inode size, which
is only stable with the IOLOCK (i_rwsem) held. Do that, it currently
calls remap_verify_area from inside the sb write protection which nests
outside the IOLOCK. But this makes fsnotify_file_area_perm which is
called from remap_verify_area unhappy when the kernel is built with
lockdep and the recently added CONFIG_FANOTIFY_ACCESS_PERMISSIONS
option.
Fix this by always calling remap_verify_area before taking the write
protection, and passing a 0 size to remap_verify_area similar to
the FICLONE/FICLONERANGE ioctls when they are asked to clone until
the file end.
(Note: the size argument gets passed to fsnotify_file_area_perm, but
then isn't actually used there).
Fixes:

fuse: make args->in_args[0] to be always the header
This change sets up FUSE operations to always have headers in args.in_args[0], even for opcodes without an actual header. This step prepares for a clean separation of payload from headers, initially it is used by fuse-over-io-uring. For opcodes without a header, we use a zero-sized struct as a placeholder. This approach: - Keeps things consistent across all FUSE operations - Will help with payload alignment later - Avoids future issues when header sizes change Op codes that already have an op code specific header do not need modification. Op codes that have neither payload nor op code headers are not modified either (FUSE_READLINK and FUSE_DESTROY). FUSE_BATCH_FORGET already has the header in the right place, but is not using fuse_copy_args - as -over-uring is currently not handling forgets it does not matter for now, but header separation will later need special attention for that op code. Correct the struct fuse_args->in_args array max size.

Especially in non-static mode the function name 'end_requests' should be prefixed with fuse_ Signed-off-by: Bernd Schubert <bschubert@ddn.com> Reviewed-by: Josef Bacik <josef@toxicpanda.com> Reviewed-by: Joanne Koong <joannelkoong@gmail.com> Reviewed-by: Luis Henriques <luis@igalia.com> Signed-off-by: Miklos Szeredi <mszeredi@redhat.com> |

* Raw NAND changes
A new controller driver, from Nuvoton, has been merged. Bastien Curutchet has contributed a series improving the Davinci controller driver, both on the organization of the code, but also on the performance side. The binding has also been converted to yaml, received a new OOB layout and now supports on-die ECC engines. The Qualcomm controller driver has been deeply cleaned to extract some parts of the code into a shared file with the Qualcomm SPI memory controller. Aside from these main changes, the Cadence binding has been converted to yaml, the brcmnand controller driver has received a small fix, otherwise some more minor changes have also made their way in. * SPI NAND changes The SPI NAND subsystem has seen a great improvement, with the advent of DTR operations (DDR operations, which may be extended to the address cycles). The first vendor driver to benefit from these improvements is the Winbond driver. A new manufacturer driver is added SkyHigh, with a new constraint for the core, it is impossible to disable the on-die ECC engine. A Foresee device is also now supported. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEE9HuaYnbmDhq/XIDIJWrqGEe9VoQFAmeSyFIACgkQJWrqGEe9 VoQqiwgAvsHzKruJpqBDNvQpNnZ0itNh9jUqP2PJ0eQ7toj1vXZ2FUPMH7s4M3/E KB5TJBIwLoSk59Un8DeTga1SuaHW37j3rWJeQUCR4jgNJ0OuYvFODfXO+4ZOXdS4 qm0prqALQsMBwrYJF8K19EoqUixraQ7WiEVhXmVN965ddYvAsW0E4VMLYg4qrnbB dvGWe5phg+UEHhmcGXola/JX5yVIC7SeBPEao267ZuRAnLH1zZS1TdllrBF0Cpeg vac1++i2E1xOkRCqaNipH2oRMiuM1L3BMPukK6pUy4InanXVT6WWm3ekqUEJARIs JHD4N//Sl7snWpIUhjkVHy9F/7r4yA== =m1w2 -----END PGP SIGNATURE----- Merge tag 'nand/for-6.14' into mtd/next * Raw NAND changes A new controller driver, from Nuvoton, has been merged.

SPI NOR changes for 6.14
Notable changes: - Add flash entries for Atmel AT25SF321, Spansion S28HL256T, S28HL02GT. - Add support for vcc-supply regulators and their DT bindings. - Drop mx25u25635f entry. The flash shares its ID with mx25u25645g and both parts have an SFDP table. Removing their entry lets them be driven by the generic SFDP-based driver. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQQTlUWNzXGEo3bFmyIR4drqP028CQUCZ4VXbBQccHJhdHl1c2hA a2VybmVsLm9yZwAKCRAR4drqP028Cb9+AQDDUObpSbXfSXCkk5pgGjPOocrKLjLc gH8+426T1qO4/gEA0tgKfCSxqX6kL7gRGdyxbWRmilfqLDsi5jnn1z3Xtgc= =ibVz -----END PGP SIGNATURE----- Merge tag 'spi-nor/for-6.14' into mtd/next SPI NOR changes for 6.14 Notable changes: - Add flash entries for Atmel AT25SF321, Spansion S28HL256T, S28HL02GT. - Add support for vcc-supply regulators and their DT bindings. - Drop mx25u25635f entry.

futex: Pass in task to futex_queue()
futex_queue() -> __futex_queue() uses 'current' as the task to store in the struct futex_q->task field. This is fine for synchronous usage of the futex infrastructure, but it's not always correct when used by io_uring where the task doing the initial futex_queue() might not be available later on. This doesn't lead to any issues currently, as the io_uring side doesn't support PI futexes, but it does leave a potentially dangling pointer which is never a good idea. Have futex_queue() take a task_struct argument, and have the regular callers pass in 'current' for that. Meanwhile io_uring can just pass in NULL, as the task should never be used off that path. In theory req->tctx->task could be used here, but there's no point populating it with a task field that will never be used anyway.
