2025-01-07drm/mst: remove mgr parameter and debug logging from drm_dp_get_vc_payload_bw()Jani Nikula
The struct drm_dp_mst_topology_mgr *mgr parameter is only used for debug logging in case the passed in link rate or lane count are zero. There's no further error checking as such, and the function returns 0. There should be no case where the parameters are zero. The returned value is generally used as a divisor, and if we were hitting this, we'd be seeing division by zero. Just remove the debug logging altogether, along with the mgr parameter, so that the function can be used in non-MST contexts without the topology manager. v2: Also remove drm_dp_mst_helper_tests_init as unnecessary (Imre) Cc: Imre Deak <imre.deak@intel.com> Cc: Lyude Paul <lyude@redhat.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Acked-by: Maxime Ripard <mripard@kernel.org> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/72d77e7a7fe69c784e9df048b7e6f250fd7599e4.1735912293.git.jani.nikula@intel.com

2025-01-07drm/i915/dp: Return early if dsc is required but not supportedAnkit Nautiyal
Currently, when bandwidth is insufficient for a given mode, we attempt to use DSC. This is indicated by a debug print, followed by a check for DSC support. The debug message states that we are trying DSC, but DSC might not be supported, which can give an incorrect picture in the logs if we bail out later. Correct the order for both DP and DP MST to: - Check if DSC is required and supported, and return early if DSC is not supported. - Print a debug message to indicate that DSC will be tried next.

2024-12-24drm/i915/dp: Refactor FEC support check in intel_dp_supports_dscAnkit Nautiyal
Forward Error Correction is required for DP if we are using DSC but is optional for eDP. Currently the helper intel_dp_supports_dsc checks if fec_enable is set for DP or not. The helper is called after fec_enable is set in crtc_state. Instead of this a better approach would be to: first, call intel_dp_supports_dsc to check for DSC support (along with FEC requirement for DP) and then set fec_enable for DP (if not already set) in crtc_state. To achieve this, remove the check for fec_enable in the helper and instead check for FEC support for DP. With this change the helper intel_dp_supports_dsc can be called earlier and return early if DSC is not supported. The structure intel_dp is added to the helper to get the FEC support for DP. v2: Pass intel_dp to adjust_limits_for_dsc_hblank_expansion_quirk instead of deriving it from connector.

2024-12-23drm/i915/gt: Log reason for setting TAINT_WARN at resetSebastian Brzezinka
TAINT_WARN is used to notify CI about non-recoverable failures, which require device to be restarted. In some cases, there is no sufficient information about the reason for the restart. The test runner is just killed, and DUT is rebooted, logging only 'probe with driver i915 failed with error -4' to dmesg. Printing error to dmesg before TAINT_WARN, would explain why the device has been restarted, and what caused the malfunction in the first place.

2024-12-20drm/i915/selftests: Use preemption timeout on cleanupJanusz Krzysztofik
Many selftests call igt_flush_test() on cleanup. With default preemption timeout of compute engines raised to 7.5 seconds, hardcoded flush timeout of 3 seconds is too short. That results in GPU forcibly wedged and kernel taineted, then IGT abort triggered. CI BAT runs loose a part of their expected coverage. Calculate the flush timeout based on the longest preemption timeout currently configured for any engine. That way, selftest can still report detected issues as non-critical, and the GPU gets a chance to recover from preemptible hangs and prepare for fluent execution of next test cases.

2024-12-19drm: make drm-active- stats optionalYunxiang Li
When memory stats is generated fresh everytime by going though all the BOs, their active information is quite easy to get. But if the stats are tracked with BO's state this becomes harder since the job scheduling part doesn't really deal with individual buffers. Make drm-active- optional to enable amdgpu to switch to the second method.

Issue seen again where engine resets fails because the engine resumes from an incorrect RING_HEAD. HEAD is still not 0 even after writing into it.
