On GPUs with RAS enabled, below call trace is observed when suspending or shutting down device. The cause is we have enabled memory wipe flag for BOs on such GPUs by default, and such BOs will go to memory wipe by amdgpu_fill_buffer, however, because ring is off already, it fails to clean up the memory and throw this error message. So add a suspend/shutdown check before wipping memory. [drm:amdgpu_fill_buffer [amdgpu]] *ERROR* Trying to clear memory with ring turned off. v2: fix coding style issue Fixes: fc6ea4be ("drm/amdgpu: Wipe all VRAM on free when RAS is enabled") Signed-off-by:

If a error happens and sink_not_reliable is set, PSR should be disabled for good but that is not happening. It would be disabled by the function handling the PSR error but then on the next fastset it would be enabled again in _intel_psr_post_plane_update(). It would only be disabled for good in the next modeset where has_psr will be set false. v2: - release psr lock before continue Fixes: 9ce5884e ("drm/i915/display: Only keep PSR enabled if there is active planes") Reported-by:

Commit 13ea6db2 ("drm/i915/edp: Ignore short pulse when panel powered off") completely broke short pulse handling for eDP as it is usually generated by sink when it is displaying image and there is some error or status that source needs to handle. When power panel is enabled, this state is enough to power aux transactions and VDD override is disabled, so intel_pps_have_power() is always returning false causing short pulses to be ignored. So here better naming this function that intends to check if aux lines are powered to avoid the endless cycle mentioned in the commit being fixed and fixing the check for what it is intended. v2: - renamed to intel_pps_have_panel_power_or_vdd() - fixed indentation Fixes: 13ea6db2 ("drm/i915/edp: Ignore short pulse when panel powered off") Cc: Anshuman Gupta <anshuman.gupta@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Cc: Uma Shankar <uma.shankar@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

struct drm_display_mode embeds a list head, so overwriting the full struct with another one will corrupt the list (if the destination mode is on a list). Use drm_mode_copy() instead which explicitly preserves the list head of the destination mode. Even if we know the destination mode is not on any list using drm_mode_copy() seems decent as it sets a good example. Bad examples of not using it might eventually get copied into code where preserving the list head actually matters. Obviously one case not covered here is when the mode itself is embedded in a larger structure and the whole structure is copied. But if we are careful when copying into modes embedded in structures I think we can be a little more reassured that bogus list heads haven't been propagated in. @is_mode_copy@ @@ drm_mode_copy(...) { ... } @depends on !is_mode_copy@ struct drm_display_mode *mode; expression E, S; @@ ( - *mode = E + drm_mode_copy(mode, &E) | - memcpy(mode, E, S) + drm_mode_copy(mode, E) ) @depends on !is_mode_copy@ struct drm_display_mode mode; expression E; @@ ( - mode = E + drm_mode_copy(&mode, &E) | - memcpy(&mode, E, S) + drm_mode_copy(&mode, E) ) @@ struct drm_display_mode *mode; @@ - &*mode + mode Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Harry Wentland <harry.wentland@amd.com> Cc: Leo Li <sunpeng.li@amd.com> Cc: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Cc: amd-gfx@lists.freedesktop.org Reviewed-by:Harry Wentland <harry.wentland@amd.com> Signed-off-by:

[Why] In dp_get_lane_status_and_lane_adjust(), we call core_link_read_dpcd() to get lane status but we ignore the return value of the function. If there is problem with AUX and we eventually can only get partial data from monitor, we might misuse the data to jude the link training result. Which could have us trapped in the dc_link_dp_perform_link_training() since we thought that we can still give a try on another link setting.
