c11a50b170 accel/qaic: Add Reliability, Accessibility, Serviceability (RAS) 
AIC100 devices generates Reliability, Availability, Serviceability events
via MHI QAIC_STATUS channel. Support such events and print a structured
log with details of the events, and if the event describes an uncorrected
error, reset the device to put it back into service. As these events may
not all be reported via other mechanisms like AER, maintain counts of
the number of errors observed for each type.

df1c3093ae drm/gem: Inline drm_gem_pin() into PRIME helpers 
Inline drm_gem_pin() into its only caller drm_gem_map_attach()
and update the documentation in the callback's purpose. Do the
equivalent for drm_gem_unpin(). Also add stricter error checking
on the involved locking.

The pin operation in the GEM object functions is a helper for
PRIME-exported buffer objects. Having drm_gem_pin() gives the
impression of a general-purpose interface, which is not the case.
Removing it makes the pin callback a bit harder to misuse.

v2:
- clarify comment on pin callback (Dmitry)

62e1e11a49 drm/client: Do not pin in drm_client_buffer_vmap() 
Pin and vmap are two distict operations. Do not mix them.

The helper drm_client_buffer_vmap() maps the pages for fbdev-dma
and fbdev-shmem. In both cases, the vmap operation ensures that
the pages are available until the vunmap happens. And as the pages
in DMA or SHMEM areas cannot be moved, there is no reason to call
pin. Hence remove the pin call.

Update drm_client_buffer_vunmap() accordingly.

v2:
- call 'locked' variants of GEM helpers (Dmitry)

2271e0a20e drm: drm_fourcc: add 10/12/16bit software decoder YCbCr formats 
This adds FOURCCs for 3-plane 10/12/16bit YCbCr formats used by software
decoders like ffmpeg, dav1d and libvpx. The intended use-case is buffer
sharing between decoders and GPUs by allocating buffers with e.g. udmabuf
or dma-heaps, avoiding unnecessary copies and format conversions in
various scenarios.

Unlike formats typically used by hardware decoders the 10/12bit formats
use a LSB alignment. In order to allow fast implementations in GL
and Vulkan the padding must contain only zeros, so the float
representation can be calculated by multiplying with 2^6=64 or 2^4=16
respectively.

MRs or branches for Mesa, Vulkan, Gstreamer, Weston and Mutter can be found at:
 - https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/34303
 - https://github.com/rmader/Vulkan-Docs/commits/ycbcr-16bit-lsb-formats/
 - https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8540
 - https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/1753
 - https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4348

The naming scheme follows the 'P' and 'Q' formats. The 'S' stands for
'software' and was selected in order to make remembering easy.

The 'Sx16' formats could as well be 'Qx16'. We stick with 'S' as 16bit software
decoders are likely much more common than hardware ones for the foreseeable
future. Note that these formats already have Vulkan equivalents:
 - VK_FORMAT_G16_B16_R16_3PLANE_420_UNORM
 - VK_FORMAT_G16_B16_R16_3PLANE_422_UNORM
 - VK_FORMAT_G16_B16_R16_3PLANE_444_UNORM

fe22d21e93 drm/vkms: Add YUV support 
Add support to the YUV formats bellow:

- NV12/NV16/NV24
- NV21/NV61/NV42
- YUV420/YUV422/YUV444
- YVU420/YVU422/YVU444

The conversion from yuv to rgb is done with fixed-point arithmetic, using
32.32 fixed-point numbers and the drm_fixed helpers.

To do the conversion, a specific matrix must be used for each color range
(DRM_COLOR_*_RANGE) and encoding (DRM_COLOR_*). This matrix is stored in
the `conversion_matrix` struct, along with the specific y_offset needed.
This matrix is queried only once, in `vkms_plane_atomic_update` and
stored in a `vkms_plane_state`. Those conversion matrices of each
encoding and range were obtained by rounding the values of the original
conversion matrices multiplied by 2^32. This is done to avoid the use of
floating point operations.

The same reading function is used for YUV and YVU formats. As the only
difference between those two category of formats is the order of field, a
simple swap in conversion matrix columns allows using the same function.

[Louis Chauvet:
- Adapted Arthur's work
- Implemented the read_line_t callbacks for yuv
- add struct conversion_matrix
- store the whole conversion_matrix in the plane state
- remove struct pixel_yuv_u8
- update the commit message
- Merge the modifications from Arthur]
