dcad6dd16e drm/display: bridge-connector: attach the encoder to the created connector
Currently all users of the bridge-connector must call
drm_connector_attach_encoder() immediately after a successful
drm_bridge_connector_init().

This is an unnecessary burden for users. Move the call to the end of
drm_bridge_connector_init() so all callers can be simplified.

Update documentation accordingly, rewording a bit the whole paragraph which
would otherwise become poorly readable due to the growing list of actions.

a5640267d6 drm/nouveau: expose VBIOS via debugfs on GSP-RM systems
When Nouveau boots with GSP-RM, it bypasses several traditional code
paths to allow GSP-RM to handle those features.  In particular,
some VBIOS parsing is skipped, and a side effect is that the VBIOS
is not exposed in the DRM debugfs entries.

Fix this by updating the drm BIOS struct (nvbios) with the VBIOS data
from the nvkm BIOS struct (nvkm_bios).  This happens normally in
NVInitVBIOS(), but that function is skipped when booting with GSP-RM.

7455a0583a accel/ivpu: Add support for limiting NPU frequency
Add configurable frequency limits to allow users to constrain the NPU
operating frequency range for power and thermal management. This support
requires firmware API version 3.34.0 or newer.

New sysfs interface:

The freq/ subdirectory contains the following attributes:

- hw_min_freq: Minimum frequency supported by hardware (read-only)
- hw_max_freq: Maximum frequency supported by hardware (read-only)
- hw_efficient_freq: Hardware's optimal operating frequency (read-only)
- current_freq: Current NPU frequency in MHz (read-only)
- set_min_freq: Configure minimum operating frequency (50XX+ devices)
- set_max_freq: Configure maximum operating frequency (50XX+ devices)

Legacy attributes npu_max_frequency_mhz and npu_current_frequency_mhz
are maintained for backward compatibility.

Implementation details:

- Frequency configuration is communicated to firmware via JSM messages
- User-specified frequency values are clamped to hardware limits
- Power-efficient frequency (pn_ratio) is adjusted dynamically to stay
  within the configured range
- Frequency configuration is initialized during device boot
- The JSM API header is updated to version 3.34.0 to support the new
  VPU_JSM_MSG_FREQ_CONFIG firmware message

Added description for the sysfs attributes in the Documentation/ABI.

c82a16b0ca drm/nouveau: WQ_PERCPU added to alloc_workqueue users
Currently if a user enqueue a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistentcy cannot be addressed without refactoring the API.

alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.

This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.

This change adds a new WQ_PERCPU flag to explicitly request
alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified.

With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.

Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

ef1b532841 drm/nouveau: replace use of system_unbound_wq with system_dfl_wq
Currently if a user enqueue a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.

This lack of consistency cannot be addressed without refactoring the API.

system_unbound_wq should be the default workqueue so as not to enforce
locality constraints for random work whenever it's not required.

Adding system_dfl_wq to encourage its use when unbound work should be used.

The old system_unbound_wq will be kept for a few release cycles.

drm/edid: add CTA Video Format Data Block support
Video Format Data Blocks (VFDBs) contain the necessary information that
needs to be fed to the Optimized Video Timings (OVT) Algorithm.
Also, we require OVT support to cover modes that aren't supported by
earlier standards (e.g. CVT). So, parse all of the relevant VFDB data
and feed it to the OVT Algorithm, to extract all of the missing OVT
modes.

- kbuild: builddeb - avoid recompiles for non-cross-compiles
 
     Avoid triggering complete rebuilds for non-cross-compile Debian
     package builds by only triggering the rebuild of host tools for
     actual cross-compile builds.
 
   - kbuild: Never respect CONFIG_WERROR / W=e to fixdep
 
     Avoid spurious rebuilds of fixdep w/ and w/o -Werror during a single
     kbuild invocation by never respecting CONFIG_WERROR for fixdep.

x86_energy_perf_policy accesses the SoC Slider via standard

which may continue to exist in a diminished role, or vanish entirely.

25ff5848c0 tools/power x86_energy_perf_policy: Enhances SoC Slider related checks
When processor_thermal_soc_slider is loaded, its slider
and offset modparams are visible.  Check that the driver
actually registered the profile named "SoC Slider" before
reading or writing these modparams.

n.b. This utility allows writing the Slider and Offset modparams
even if the driver policy is not "balanced".  Currently the
processor_thermal_soc_slider consults those modparams
only in "balanced" mode.

clk: bcm: rpi: Mark VEC clock as CLK_IGNORE_UNUSED
On Raspberry Pi 3B, the VEC clock is used by the VideoCore firmware
display driver, which remains active until the vc4 driver loads and
sends NOTIFY_DISPLAY_DONE. If this clock is disabled during boot, a bus
lockup happens and the firmware becomes unresponsive, causing a complete
system lockup.

Mark the VEC clock with CLK_IGNORE_UNUSED so it survives the unused
clock disablement and remains available until the vc4 driver takes over
display management.

27d128c1cf ring-buffer fix for 7.1:
- Fix accounting of persistent ring buffer rewind
 
   On boot up, the head page is moved back to the earliest point of
   the saved ring buffer. This is because the ring buffer being read by
   user space on a crash may not save the part it read. Rewinding the head
   page back to the earliest saved position helps keep those events from
   being lost.
 
   The number of events is also read during boot up and displayed in the
   stats file in the tracefs directory. It's also used for other accounting
   as well. On boot up, the "reader page" is accounted for but a rewind may
   put it back into the buffer and then the reader page may be accounted
   for again.
 
   Save off the original reader page and skip accounting it when scanning
   the pages in the ring buffer.

Merge tag 'io_uring-7.1-20260424' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux

Pull io_uring fixes from Jens Axboe:

 - Fix for a NOMMU bug with io_uring, where NOMMU doesn't grab page refs
   at mmap time. NOMMU also has entirely broken FOLL_PIN support, yet
   here we are

 - A few fixes covering minor issues introduced in this merge window

 - data race annotation to shut up KCSAN for when io-wq limits are
   applied

 - A nospec addition for direct descriptor file updating. Rest of the
   direct descriptor path already had this, but for some reason the
   update did not. Now they are all the same

 - Various minor defensive changes that claude identified and suggested
   terrible fixes for, turned into actually useful cleanups:

       - Use kvfree() for the imu cache. These can come from kmalloc or
         vmalloc depending on size, but the in-cache ones are capped
         where it's always kmalloc based. Change to kvfree() in the
         cleanup path, making future changes unlikely to mess that up

       - Negative kbuf consumption lengths. Can't happen right now, but
         cqe->res is used directly, which if other codes changes could
         then be an error value

 - Fix for an issue with the futex code, where partial wakes on a
   vectored fuxes would potentially wake the same futex twice, rather
   than move on to the next one. This could confuse an application as it
   would've expected the next futex to have been woken

 - Fix for a bug with ring resizing, where SQEs or CQEs might not have
   been copied correctly if large SQEs or CQEs are used in the ring.
   Application side issue, where SQEs or CQEs might have been lost
   during resize

 - Fix for a bug where EPOLL_URING_WAKE might have been lost, causing a
   multishot poll to not be terminated when it's nested, like it should
   have been

 - Fix for an issue with signed comparison of poll references for the
   slow path

 - Fix for a user struct UAF in the zcrx code

 - Two minor zcrx cleanups

* tag 'io_uring-7.1-20260424' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux:
  io_uring: take page references for NOMMU pbuf_ring mmaps
  io_uring/poll: ensure EPOLL_ONESHOT is propagated for EPOLL_URING_WAKE
  io_uring/zcrx: warn on freelist violations
  io_uring/zcrx: clear RQ headers on init
  io_uring/zcrx: fix user_struct uaf
  io_uring/register: fix ring resizing with mixed/large SQEs/CQEs
  io_uring/futex: ensure partial wakes are appropriately dequeued
  io_uring/rw: add defensive hardening for negative kbuf lengths
  io_uring/rsrc: use kvfree() for the imu cache
  io_uring/rsrc: unify nospec indexing for direct descriptors
  io_uring: fix spurious fput in registered ring path
  io_uring: fix iowq_limits data race in tctx node addition
  io_uring/tctx: mark io_wq as exiting before error path teardown
  io_uring/tctx: check for setup tctx->io_wq before teardown
  io_uring/poll: fix signed comparison in io_poll_get_ownership()
