The offending commit is daf8de0874 ("drm/amdgpu: always reset the asic in
suspend (v2)"). Commit 34452ac303 ("drm/amdgpu: don't use BACO for
reset in S3 ") doesn't help, so the issue is something different.
Assuming that to make HDA resume to D0 fully realized, it needs to be
successfully put to D3 first. And this guesswork proves working, by
moving amdgpu_asic_reset() to noirq callback, so it's called after HDA
function is in D3.

"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as
documented in supported_modes of drm_plane_create_blend_mode_property():
https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c
In this mode, both 'pixel alpha' and 'plane alpha' participate in the
calculation, as described by the pixel blend mode formula in KMS/DRM
documentation:
out.rgb = plane_alpha * fg.rgb +
(1 - (plane_alpha * fg.alpha)) * bg.rgb
Considering the blend config mechanisms we have in the driver so far,
the alpha mode that better fits this blend mode is the
_PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain
is the plane alpha (global_alpha).
With this change, alpha property stops to be ignored. It also addresses
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1734

* keep the 8-bit value for global_alpha_value (Nicholas)
* correct the logical ordering for combined global gain (Nicholas)
* apply to dcn10 too (Nicholas)

The bug [1] was introduced by commit 27599aacba ("fbdev: Hot-unplug

have an underlying platform device, which can be hot-unplugged
before loading the native graphics driver. OF framebuffers do not
(yet) have that device. Fix the code by unregistering the framebuffer
as before without a hot unplug.

MIPI-DSI devices, if they are controlled through the bus itself, have to
be described as a child node of the controller they are attached to.
Thus, there's no requirement on the controller having an OF-Graph output
port to model the data stream: it's assumed that it would go from the
parent to the child.
However, some bridges controlled through the DSI bus still require an
input OF-Graph port, thus requiring a controller with an OF-Graph output
port. This prevents those bridges from being used with the controllers
that do not have one without any particular reason to.
Let's drop that requirement.

adds the newly requested feature to the permission bitmap instead of
overwriting it. Add a selftest which validates that.
- Unroll string MMIO for encrypted SEV guests as the hypervisor cannot
emulate it.
- Handle supervisor states correctly in the FPU/XSTATE code so it takes
the feature set of the fpstate buffer into account. The feature sets
can differ between host and guest buffers. Guest buffers do not contain
supervisor states. So far this was not an issue, but with enabling
PASID it needs to be handled in the buffer offset calculation and in
the permission bitmaps.
- Avoid a gazillion of repeated CPUID invocations in by caching the values
early in the FPU/XSTATE code.
- Enable CONFIG_WERROR for X86.
- Make the X86 defconfigs more useful by adapting them to Y2022 reality.

This reverts commit 7dabfa2bc4. There are
multiple reports that this breaks boot on various systems. The common
theme is that orphan clks are having rates set on them when that isn't
expected. Let's revert it out for now so that -rc1 boots.
