38476bde59 drm/amdgpu/userq: call dma_resv_wait_timeout without test for signalled
In function amdgpu_userq_gem_va_unmap_validate call
dma_resv_wait_timeout directly. Also since we are waiting
forever we should not be having any return value and hence
no handling needed.

d65bfb1782 drm/amd/display: Change dither policy for 10 bpc output back to dithering
Commit d5df648ec8 ("drm/amd/display: Change dither policy for 10bpc to
round") degraded display of 12 bpc color precision output to 10 bpc sinks
by switching 10 bpc output from dithering to "truncate to 10 bpc".

I don't find the argumentation in that commit convincing, but the
consequences highly unfortunate, especially for applications that
require effective > 10 bpc precision output of > 10 bpc framebuffers.

The argument wasn't something strong like "there are hardware design
defects or limitations which require us to work around broken dithering
to 10 bpc", or "there are some special use cases which do require
truncation to 10 bpc", but essentially "at some point in the past we
used truncation in Polaris/Vega times and it looks like it got
inadvertently changed for Navi, so let's do that again". I couldn't find
evidence for that in the git commit logs for this. The commit message also
acknowledges that using dithering "...makes some sense for FP16...
...but not for ARGB2101010 surfaces..."

The problem with this is that it makes fp16 surfaces, and especially
rgba16 fixed point surfaces, less useful. These are now well
supported by Mesa 25.3 and later via OpenGL + EGL, Vulkan/WSI, and by
OSS AMDVLK Vulkan/WSI/display, and also by GNOME 50 mutter under Wayland,
and they used to provide more than 10 bpc effective precision at the
output.

Even for 8 or 10 bpc surfaces, the color pipeline behind the framebuffer,
e.g., gamma tables, CTM, can be used for color correction and will
benefit from an effective > 10 bpc output precision via dithering,
retaining some precision that would get lost on the way through the
pipeline, e.g., due to non-linear gamma functions.

Scientific apps rely on this for > 10 bpc display precision. Truncating
to 10 bpc, instead of dithering the pipeline internal 12 bpc precision
down to 10 bpc, causes a serious loss of precision. This also creates the
undesirable and slightly absurd situation that using a cheap monitor
with only 8 bpc input and display panel will yield roughly 12 bpc
precision via dithering from 12 -> 8 bpc, whereas investment into a
more expensive monitor with 10 bpc input and native 10 bpc display will
only yield 10 bpc, even if a fp16 or rgb16 framebuffer and/or a properly
set up color pipeline (gamma tables, CTM's etc. with more than 10 bpc out
precision) would allow effective 12 bpc precision output.

Therefore this patch proposes reverting that commit and going back to
dithering down to 10 bpc, consistent with the behaviour for 6 bpc or 8 bpc
output.

Successfully tested on AMD Polaris DCE 11.2 and Raven Ridge DCN 1.0 with
a native 10 bpc capable monitor, outputting a RGBA16 unorm framebuffer and
measuring resulting color precision with a photometer. No apparent visual
artifacts or problems were observed, and effective precision was measured
to be 12 bpc again, as expected.

3c863ff920 drm/amdgpu: replace PASID IDR with XArray
Replace the PASID IDR + spinlock with XArray as noted in the TODO
left by commit ea56aa2625 ("drm/amdgpu: fix the idr allocation
flags").

The IDR conversion still has an IRQ safety issue:
amdgpu_pasid_free() can be called from hardirq context via the fence
signal path, but amdgpu_pasid_idr_lock is taken with plain spin_lock()
in process context, creating a potential deadlock:

     CPU0
     ----
     spin_lock(&amdgpu_pasid_idr_lock)   // process context, IRQs on
     <Interrupt>
       spin_lock(&amdgpu_pasid_idr_lock) // deadlock

   The hardirq call chain is:

     sdma_v6_0_process_trap_irq
      -> amdgpu_fence_process
       -> dma_fence_signal
        -> drm_sched_job_done
         -> dma_fence_signal
          -> amdgpu_pasid_free_cb
           -> amdgpu_pasid_free

Use XArray with XA_FLAGS_LOCK_IRQ (all xa operations use IRQ-safe
locking internally) and XA_FLAGS_ALLOC1 (zero is not a valid PASID).
Both xa_alloc_cyclic() and xa_erase() then handle locking
consistently, fixing the IRQ safety issue and removing the need for
an explicit spinlock.

v8: squash in irq safe fix

592713a896 drm/amd/pm: correct mem_busy_percent display due to calculation errors
PMFW may return invalid values due to internal calculation errors.
so, the kmd driver must validate and sanitize the returned values to
prevent issues caused by firmware calculation errors.

For example, values 0xfffe (-2) and 0xffff (-1) are treated
as invalid and clamped to 0.

this applies to devices with CAB (Cache As Buffer) functionality.

95a599c8a2 drm/radeon: add WQ_PERCPU to alloc_workqueue users
This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:

   commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
   commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")

The refactoring is going to alter the default behavior of
alloc_workqueue() to be unbound by default.

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. For more details see the Link tag below.

In order to keep alloc_workqueue() behavior identical, explicitly request
WQ_PERCPU.

The point of the refactoring is to eventually alter the default behavior of
workqueues to become unbound by default so that their workload placement is
optimized by the scheduler.

Before that to happen after a careful review and conversion of each individual
case, workqueue users must be converted to the better named new workqueues with
no intended behaviour changes:

   system_wq -> system_percpu_wq
   system_unbound_wq -> system_dfl_wq

This way the old obsolete workqueues (system_wq, system_unbound_wq) can be
removed in the future.

1d0a26cf37 drm/amdgpu: add CONFIG_GCOV_PROFILE_AMDGPU Kconfig option
Add a Kconfig option to enable GCOV code coverage profiling for the
amdgpu driver, following the established upstream pattern used by
CONFIG_GCOV_PROFILE_FTRACE (kernel/trace), CONFIG_GCOV_PROFILE_RDS
(net/rds), and CONFIG_GCOV_PROFILE_URING (io_uring).

This allows CI systems to enable amdgpu code coverage entirely via
.config (e.g., scripts/config --enable GCOV_PROFILE_AMDGPU) without
manually editing the amdgpu Makefile. The option depends on both
DRM_AMDGPU and GCOV_KERNEL, defaults to n, and is therefore never
enabled in production or distro builds.

4e8197426f drm/amd/display: Fix missing parameter details in amdgpu_dm_ism
Update comments in dm_ism_get_idle_allow_delay() and
dm_ism_insert_record() to better reflect their behavior and inputs.

dm_ism_get_idle_allow_delay() computes the delay before allowing
idle optimizations based on history and stream timing.

dm_ism_insert_record() stores idle duration records in the
circular history buffer.

These functions explain what they do, but they do not explain what their
inputs mean.

fc0ed906f1 drm/amd/display: Wire up dcn10_dio_construct() for all pre-DCN401 generations
Description:
 - Commit b82f075934 ("drm/amd/display: Migrate DIO registers access
   from hwseq to dio component") moved DIO_MEM_PWR_CTRL register access
   behind the new dio abstraction layer but only created the dio object for
   DCN 4.01. On all other generations (DCN 10/20/21/201/30/301/302/303/
   31/314/315/316/32/321/35/351/36), the dio pointer is NULL, causing the
   register write to be silently skipped.

   This results in AFMT HDMI memory not being powered on during init_hw,
   which can cause HDMI audio failures and display issues on affected
   hardware including Renoir/Cezanne (DCN 2.1) APUs that use dcn10_init_hw.

   Call dcn10_dio_construct() in each older DCN generation's resource.c
   to create the dio object, following the same pattern as DCN 4.01. This
   ensures the dio pointer is non-NULL and the mem_pwr_ctrl callback works
   through the dio abstraction for all DCN generations.
