[why] dcn301_calculate_wm_and_dl() causes flickering when external monitor is connected. This issue has been fixed before by commit 0e4c0ae5 ("drm/amdgpu/display: drop dcn301_calculate_wm_and_dl for now"), however part of the fix was gone after commit 2cbcb78c ("Merge tag 'amd-drm-next-5.13-2021-03-23' of https://gitlab.freedesktop.org/agd5f/linux into drm-next"). [how] Use dcn30_calculate_wm_and_dlg() instead as in the original fix.

The TA has a limit to the amount of data that can be retrieved from GET_TOPOLOGY. For setups that exceed this limit, the xGMI topology needs to be re-initialized and data needs to be re-fetched from the extended link records by setting a flag in the shared command buffer. The number of hops and the number of links must be accumulated by the driver. Other data points are all fetched from the first request. Because the TA has already exceeded its link record limit, it cannot hold bidirectional information. Otherwise the driver would have to do more than two fetches so the driver has to reflect the topology information in the opposite direction. v2: squashed with internal reviewed fix Signed-off-by:

[Why] PSR can disable the HUBP along with the OTG when PSR is active. We'll hit a pageflip timeout when the OTG is disable because we're no longer updating the CRTC vblank counter and the pflip high IRQ will not fire on the flip. In order to flip the page flip timeout occur we should modify the enter/exit conditions to match DRM requirements. [How] Use our deferred handlers for DRM vblank control to notify DMCU(B) when it can enable or disable PSR based on whether vblank is disabled or enabled respectively. We'll need to pass along the stream with the notification now because we want to access the CRTC state while the CRTC is locked to get the stream state prior to the commit. Retain a reference to the stream so it remains safe to continue to access and release that reference once we're done with it. Enable/disable logic follows what we were previously doing in update_planes. The workqueue has to be flushed before programming streams or planes to ensure that we exit out of idle optimizations and PSR before these events occur if necessary. To keep the skip count logic the same to avoid FBCON PSR enablement requires copying the allow condition onto the DM IRQ parameters - a field that we can actually access from the worker. Reviewed-by:

[Why] The current implementation for idle optimization support only has a single work item that gets reshuffled into the system workqueue whenever we receive an enable or disable event. We can have mismatched events if the work hasn't been processed or if we're getting control events from multiple displays at once. This fixes this issue and also makes the implementation usable for PSR control - which will be addressed in another patch. [How] We need to be able to flush remaining work out on demand for driver stop and psr disable so create a driver specific workqueue instead of using the system one. The workqueue will be single threaded to guarantee the ordering of enable/disable events. Refactor the queue to allocate the control work and deallocate it after processing it. Pass the acrtc directly to make it easier to handle psr enable/disable in a later patch. Rename things to indicate that it's not just MALL specific. Reviewed-by:

[Why] While reading remote EDID via Startech 1-to-4 hub, occasionally we won't get response in time and won't light up corresponding monitor. Ideally, we can still add generic modes for userspace to choose to try to light up the monitor and which is done in drm_helper_probe_single_connector_modes(). So the main problem here is that we fail .mode_valid since we don't create remote dc_sink for this case. [How] Also add default dc_sink if we can't get the EDID. Reviewed-by:

Why: Previously hw fence is alloced separately with job. It caused historical lifetime issues and corner cases. The ideal situation is to take fence to manage both job and fence's lifetime, and simplify the design of gpu-scheduler. How: We propose to embed hw_fence into amdgpu_job. 1. We cover the normal job submission by this method. 2. For ib_test, and submit without a parent job keep the legacy way to create a hw fence separately. v2: use AMDGPU_FENCE_FLAG_EMBED_IN_JOB_BIT to show that the fence is embedded in a job. v3: remove redundant variable ring in amdgpu_job v4: add tdr sequence support for this feature. Add a job_run_counter to indicate whether this job is a resubmit job. v5 add missing handling in amdgpu_fence_enable_signaling Signed-off-by:
