2024-09-18drm/amd/display: Implement new DPCD register handlingRyan Seto
[WHY] There are some monitor timings that seem to be supported without DSC but actually require DSC to be displayed. A VESA SCR introduced a new max uncompressed pixel rate cap register that we can use to handle these edge cases. [HOW] SST: Read caps from link and invalidate timings that exceed the max limit but do not support DSC. Then check for options override when determining BPP. MST: Read caps from virtual DPCD peer device or daisy chained SST monitor and set validation set BPPs to max if pixel rate exceeds uncompressed limit. Validation set optimization continues as normal.

2024-09-18drm/amdgpu: nuke the VM PD/PT shadow handlingChristian König
This was only used as workaround for recovering the page tables after VRAM was lost and is no longer necessary after the function amdgpu_vm_bo_reset_state_machine() started to do the same. Compute never used shadows either, so the only proplematic case left is SVM and that is most likely not recoverable in any way when VRAM is lost.

2024-09-18drm/amdgpu: Retry i2c transfer once if it fails on SMU13.0.6Kent Russell
During init, there can be some collisions on the i2c bus that result in the EEPROM read failing. This has been mitigated in the PMFW to a degree, but there is still a small chance that the bus will be busy. When the read fails during RAS init, that disables page retirement altogether, which is obviously not ideal. To try to avoid that situation, set the eeprom_read function to retry once if the first read fails, specifically for smu_v13_0_6.

2024-09-16drm/i915/dp: Fix AUX IO power enabling for eDP PSRImre Deak
Panel Self Refresh on eDP requires the AUX IO power to be enabled whenever the output (main link) is enabled. This is required by the AUX_PHY_WAKE/ML_PHY_LOCK signaling initiated by the HW automatically to re-enable the main link after it got disabled in power saving states (see eDP v1.4b, sections 5.1, 6.1.3.3.1.1). The Panel Replay mode on non-eDP outputs on the other hand is only supported by keeping the main link active, thus not requiring the above AUX_PHY_WAKE/ML_PHY_LOCK signaling (eDP v1.4b, section 6.1.3.3.1.2). Thus enabling the AUX IO power for this case is not required either. Based on the above enable the AUX IO power only for eDP/PSR outputs. Bspec: 49274, 53370 v2: - Add a TODO comment to adjust the requirement for AUX IO based on whether the ALPM/main-link off mode gets enabled.

So, pm_runtime_get_if_active() will be called and return 0 because rpm status != ACTIVE (but equal SUSPENDING or RESUMING). v2: Still get the reference even on non suspending/resuming path (Jonathan, Brost).

2024-09-12drm/xe: prevent potential UAF in pf_provision_vf_ggtt()Matthew Auld
The node ptr can point to an already freed ptr, if we hit the path with an already allocated node. We later dereference that pointer with: xe_gt_assert(gt, !xe_ggtt_node_allocated(node)); which is a potential UAF. Fix this by not stashing the ptr for node. Also since it is likely a bad idea to leave config->ggtt_region pointing to a stale ptr, also set that to NULL by calling pf_release_vf_config_ggtt() instead of pf_release_ggtt().

2024-09-11drm/amd/display: Add all planes on CRTC to state for overlay cursorLeo Li
[Why] DC has a special commit path for native cursor, which use the built-in cursor pipe within DCN planes. This update path does not require all enabled planes to be added to the list of surface updates sent to DC. This is not the case for overlay cursor; it uses the same path as MPO commits. This update path requires all enabled planes to be added to the list of surface updates sent to DC. Otherwise, DC will disable planes not inside the list. [How] If overlay cursor is needed, add all planes on the same CRTC as this cursor to the atomic state. This is already done for non-cursor planes (MPO), just before the added lines.

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Three cleanups - Drop stale exynos file pattern from MAINTAINERS file The old "exynos" directory is removed from MAINTAINERS as Samsung Exynos display bindings have been relocated. This resolves a warning from get_maintainers.pl about no files matching the outdated directory. - Constify struct exynos_drm_ipp_funcs By making struct exynos_drm_ipp_funcs constant, the patch enhances security by moving the structure to a read-only section of memory. This change results in a slight reduction in the data section size. - Remove unnecessary code The function exynos_atomic_commit is removed as it became redundant after a previous update. This cleans up the code and eliminates unused function declarations. One fixup - Fix wrong assignment in gsc_bind() A double assignment in gsc_bind() was flagged by the cocci tool and corrected to fix an incorrect assignment, addressing a potential issue introduced in a prior commit.
