drm/rockchip: Don't spam logs in atomic check

2023-08-16T16:32:27+00:00

commit 43dae319b50fac075ad864f84501c703ef20eb2b upstream. Userspace should not be able to trigger DRM_ERROR messages to spam the logs; especially not through atomic commit parameters which are completely legitimate for userspace to attempt.

drm/nouveau: remove unused tu102_gr_load() function

2023-08-16T16:32:26+00:00

commit 421dabcad1c69e02a41c0d601aefbc29ee3f5368 upstream. tu102_gr_load() is completely unused and can be removed to address this warning: drivers/gpu/drm/nouveau/dispnv50/disp.c:2517:1: error: no previous prototype for 'nv50_display_create' Another patch was sent in the meantime to mark the function static but that would just cause a different warning about an unused function.

drm/bridge: it6505: Check power state with it6505->powered in IRQ handler

2023-08-16T16:32:26+00:00

commit e9d699af3f65d62cf195f0e7a039400093ab2af2 upstream. On system resume, the driver might call it6505_poweron directly if the runtime PM hasn't been enabled. In such case, pm_runtime_get_if_in_use will always return 0 because dev->power.runtime_status stays at RPM_SUSPENDED, and the IRQ will never be handled. Use it6505->powered from the driver struct fixes this because it always gets updated when it6505_poweron is called.

drm/amd/display: Don't show stack trace for missing eDP

commit 7ad1dfc144cbf62702fd07838da8fd8a77921083 upstream. Some systems are only connected by HDMI or DP, so warning related to missing eDP is unnecessary. Downgrade to debug instead.

drm/nouveau/disp: Revert a NULL check inside nouveau_connector_get_modes

2023-08-16T16:32:22+00:00

commit d5712cd22b9cf109fded1b7f178f4c1888c8b84b upstream. The original commit adding that check tried to protect the kenrel against a potential invalid NULL pointer access. However we call nouveau_connector_detect_depth once without a native_mode set on purpose for non LVDS connectors and this broke DP support in a few cases.

drm/amd/pm: avoid unintentional shutdown due to temperature momentary fluctuation

2023-08-16T16:32:20+00:00

commit b75efe88b20c2be28b67e2821a794cc183e32374 upstream. An intentional delay is added on soft ctf triggered. Then there will be a double check for the GPU temperature before taking further action. This can avoid unintended shutdown due to temperature momentary fluctuation.

drm/amd: Disable S/G for APUs when 64GB or more host memory

2023-08-16T16:32:19+00:00

commit 08fffa74d9772d9538338be3f304006c94dde6f0 upstream. Users report a white flickering screen on multiple systems that is tied to having 64GB or more memory. When S/G is enabled pages will get pinned to both VRAM carve out and system RAM leading to this. Until it can be fixed properly, disable S/G when 64GB of memory or more is detected. This will force pages to be pinned into VRAM. This should fix white screen flickers but if VRAM pressure is encountered may lead to black screens. It's a trade-off for now.

drm/amd/display: check attr flag before set cursor degamma on DCN3+

2023-08-16T16:32:19+00:00

commit 96b020e2163fb2197266b2f71b1007495206e6bb upstream. Don't set predefined degamma curve to cursor plane if the cursor attribute flag is not set. Applying a degamma curve to the cursor by default breaks userspace expectation. Checking the flag before performing any color transformation prevents too dark cursor gamma in DCN3+ on many Linux desktop environment (KDE Plasma, GNOME, wlroots-based, etc.) as reported at: - https://gitlab.freedesktop.org/drm/amd/-/issues/1513 This is the same approach followed by DCN2 drivers where the issue is not present.
