2023-09-20drm/amd/display: Update driver and IPS interopDuncan Ma2-0/+6
[Why] Two issues fixed: 1. Currently, driver does not allow idle prior to PSR entry. Once PSR1+IPS is enabled, there is intermittent hang due to DCN access from IrqMgr during IPS2. 2. Driver is sending multiple commands to PMFW and dmcub to exit IPS even during IPS0. [How] 1. Set driver allow optimization prior to entering PSR mode with the condition for eDP display only. Unregister all interrupts before allowing driver idle and re-register interrupts when exiting from idle. This will prevent IrqMgr to access DCN during IPS2. 2. Block sending PMFW and dmcub exit low power state commands when driver is not in idle state.

[HOW & Why] There seems to be an issue with 2nd DPIA acquiring link encoder for tiled displays. Solution is to remove check for eng_id before we get first dynamic encoder for it Reviewed-by: Cruise Hung <cruise.hung@amd.com> Reviewed-by: Meenakshikumar Somasundaram <meenakshikumar.somasundaram@amd.com> Cc: Mario Limonciello <mario.limonciello@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org Acked-by: Stylon Wang <stylon.wang@amd.com> Signed-off-by: Mustapha Ghaddar <mghaddar@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2023-09-12drm/amd/display: do not block ODM + OPM on one side of the screenWenjing Liu1-7/+0
[why] build scaling param is overriding validation policy regarding small viewport support. Even if ODM + windowed MPO is not supported. The decision has to be made at the time of validation. When building scaling params, we might be building an initial dc state as an input to DML validation. The initial state is not supposed to be always valid and we rely on DML to modify the initial dc state and determine the final validation result. This check is pre judging validation result when building the initial dc state. This causes an issue where we are transitioning from desktop only ODM combine 2:1 to ODM bypass with 2 planes. In this case we are building an initial state with with ODM 2:1 combine + 2 planes. This is indeed not supported but DML is about to modify the state so it no longer uses ODM combine. Before it reaches DML, dc resource already fails validation because it checks that the initial state is not supported by our policy. This overrides the ODM decision to validate this state with ODM combine disabled. Therefore causes an unexpected validation failure when the secondary plane is added on one side of the screen.

2023-09-12drm/amd/display: Don't check registers, if using AUX BL controlSwapnil Patel1-1/+3
[Why] Currently the driver looks DCN registers to access if BL is on or not. This check is not valid if we are using AUX based brightness control. This causes driver to not send out "backlight off" command during power off sequence as it already thinks it is off. [How] Only check DCN registers if we aren't using AUX based brightness control.
