drm: Fix DSC BPP increment decoding

2025-02-13T08:20:30Z

Starting with DPCD version 2.0 bits 6:3 of the DP_DSC_BITS_PER_PIXEL_INC DPCD register contains the NativeYCbCr422_MAX_bpp_DELTA field, which can be non-zero as opposed to earlier DPCD versions, hence decoding the bit_per_pixel increment value at bits 2:0 in the same register requires applying a mask, do so.

drm/print: Include drm_device.h

2025-01-25T20:55:55Z

The header drm_print.h uses members of struct drm_device pointers, as such, it should include drm_device.h to let the compiler know the full type definition. Without such include, users of drm_print.h that don't explicitly need drm_device.h would bump into build errors and be forced to include the latter.

drm/xe: remove unused xe_pciids.h harder, add missing PCI ID

2025-01-10T09:02:15Z

Commit 493454445c95 ("drm/xe: switch to common PCI ID macros") removed xe_pciids.h via drm-intel-next. In the mean time, commit ae78ec0a52c4 ("drm/xe/ptl: Add another PTL PCI ID") added to xe_pciids.h via drm-xe-next. The two commits were merged in commit 8f109f287fdc ("Merge drm/drm-next into drm-xe-next"), but xe_pciids.h wasn't removed, and the PCI ID wasn't added to pciids.h. Remove xe_pciids.h, and add the PCI ID to pciids.h.

drm/ttm: Handle cgroup based eviction in TTM

2025-01-10T08:54:49Z

cgroup resource allocation has to be handled in TTM, so -EAGAIN from cgroups can be converted into -ENOSPC, and the limitcg can be properly evicted in ttm code. When hitting a resource limit through -EAGAIN, the cgroup for which the limit is hit is also returned. This allows eviction to delete only from cgroups which are a subgroup of the current cgroup. The returned CSS is used to determine if eviction is valuable for a given resource, and allows TTM to only target specific resources to lower memory usage.
