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

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

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/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.

drm/amd/display: Fix a regression on Polaris cards

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

commit 3bb575572bf498a9d39e9d1ca5c06cc3152928a1 upstream. DCE products don't define a `remove_stream_from_ctx` like DCN ones do. This means that when compute_mst_dsc_configs_for_state() is called it always returns -EINVAL which causes MST to fail to setup.
