2022-06-21drm/amd/display: Fix divide-by-zero in DPPCLK and DISPCLK calculationGeorge Shen1-8/+10
[Why] Certain use cases will pass in zero in the new_clocks parameter for all clocks. This results in a divide-by-zero error when attempting to round up the new clock. When new_clocks are zero, no rounding is required, so we can skip it. [How] Guard the division calculation with a check to make sure clocks are not zero.

2022-06-21drm/amd/display: Update DPPCLK programming sequenceAlvin Lee1-1/+24
[Description] - When lowering DPPCLK, we want to program the DPP DTO before updating the DPP refclk. - Also update DPPCLK to the exact frequency that will be set after clock divider has been programmed. This will prevent rounding errors when making the request to PMFW (we need DPP DTO to match exactly with the exact DPP refclk).

2022-06-21drm/amd/display: Release remote dc_sink under mst scenarioWayne Lin3-22/+35
[Why] Observe that we have several problems while releasing remote dc_sink under mst cases. - When unplug mst branch device from the source, we now try to free all remote dc_sinks in dm_helpers_dp_mst_stop_top_mgr(). However, there are bugs while we're releasing dc_sinks here. First of all, link->remote_sinks[] array get shuffled within dc_link_remove_remote_sink(). As the result, increasing the array index within the releasing loop is wrong. Secondly, it tries to call dc_sink_release() to release the dc_sink of the same aconnector every time in the loop. Which can't release dc_sink of all aconnector in the mst topology. - There is no code path for us to release remote dc_sink for disconnected sst monitor which unplug event is notified by CSN sideband message. Which means we'll use stale dc_sink data to represent later on connected monitor. Also, has chance to break the maximum remote dc_sink number constraint. [How] Distinguish unplug event of mst scenario into 2 cases. * Unplug sst/legacy stream sink off the mst topology - Release related remote dc_sink in detec_ctx(). * Unplug mst branch device off the mst topology - Release related remote dc_sink in early_unregister() Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Reviewed-by: Aurabindo Jayamohanan Pillai <Aurabindo.Pillai@amd.com> Acked-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Acked-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

For stream sinks whithin the same mst topology, they share the same dc_link. dm_set_dpms_off() tries to update one mst stream only which is incomplete. - Setting dpms off should be triggered by usermode.

This reverts commit 035f54969bb2c1a5ced52f43e4ef393e0c0f6bfa. The reverted commit was trying to fix side effect brought by commit 3c4d55c9b9be ("drm/amd/display: turn DPMS off on connector unplug") However, * This reverted commit will have mst case never call dm_set_dpms_off() which conflicts the idea of original commit 3c4d55c9b9be ("drm/amd/display: turn DPMS off on connector unplug") That's due to dm_crtc_state is always null since the input parameter aconnector is the root device (source) of mst topology. It's not an end stream sink within the mst topology. * Setting dpms off should be triggered by usermode. Besdies, it seems usermode does release relevant resource for mst & non-mst case when unplug connecotr now.

2022-06-14drm/amd/display: Blank for uclk OC in dm instead of dcJoshua Aberback2-30/+14
[Why] All displays need to be blanked during the uclk OC interface so that we can guarantee pstate switching support. If the display config doesn't support pstate switching, only using core_link_disable_stream will not enable it as the front-end is untouched. We need to go through the full plane removal sequence to properly program the pipe to allow pstate switching.

2022-06-14drm/amd/display: Firmware assisted MCLK switch and FSFelipe Clark14-22/+51
[WHY] Memory clock switching has great potential for power savings. [HOW] The driver code was modified to notify the DMCUB firmware that it should stretch the vertical blank of frames when a memory clock switch is about to start so that no blackouts happen on the screen due to unavailability of the frame buffer. The driver logic to determine when such firmware assisted strategy can be initiated is also implemented and consists on checking prerequisites of the feature.
