Merge tag 'drm-fixes-2024-05-03' of https://gitlab.freedesktop.org/drm/kernel
Pull drm fixes from Dave Airlie: "Weekly fixes, mostly made up from amdgpu and some panel changes. Otherwise xe, nouveau, vmwgfx and a couple of others, all seems pretty on track. amdgpu: - Fix VRAM memory accounting - DCN 3.1 fixes - DCN 2.0 fix - DCN 3.1.5 fix - DCN 3.5 fix - DCN 3.2.1 fix - DP fixes - Seamless boot fix - Fix call order in amdgpu_ttm_move() - Fix doorbell regression - Disable panel replay temporarily amdkfd: - Flush wq before creating kfd process xe: - Fix UAF on rebind worker - Fix ADL-N display integration imagination: - fix page-count macro nouveau: - avoid page-table allocation failures - fix firmware memory allocation panel: - ili9341: avoid OF for device properties; respect deferred probe; fix usage of errno codes ttm: - fix status output vmwgfx: - fix legacy display unit - fix read length in fence signalling" * tag 'drm-fixes-2024-05-03' of https://gitlab.freedesktop.org/drm/kernel: (25 commits) drm/xe/display: Fix ADL-N detection drm/panel: ili9341: Use predefined error codes drm/panel: ili9341: Respect deferred probe drm/panel: ili9341: Correct use of device property APIs drm/xe/vm: prevent UAF in rebind_work_func() drm/amd/display: Disable panel replay by default for now drm/amdgpu: fix doorbell regression drm/amdkfd: Flush the process wq before creating a kfd_process drm/amd/display: Disable seamless boot on 128b/132b encoding drm/amd/display: Fix DC mode screen flickering on DCN321 drm/amd/display: Add VCO speed parameter for DCN31 FPU drm/amdgpu: once more fix the call oder in amdgpu_ttm_move() v2 drm/amd/display: Allocate zero bw after bw alloc enable drm/amd/display: Fix incorrect DSC instance for MST drm/amd/display: Atom Integrated System Info v2_2 for DCN35 drm/amd/display: Add dtbclk access to dcn315 drm/amd/display: Ensure that dmcub support flag is set for DCN20 drm/amd/display: Handle Y carry-over in VCP X.Y calculation drm/amdgpu: Fix VRAM memory accounting drm/vmwgfx: Fix invalid reads in fence signaled events ...
