2024-06-14drm/amd/display: Wake DMCUB before sending a command for replay featureNicholas Kazlauskas1-3/+3
[Why] We can hang in place trying to send commands when the DMCUB isn't powered on. [How] For functions that execute within a DC context or DC lock we can wrap the direct calls to dm_execute_dmub_cmd/list with code that exits idle power optimizations and reallows once we're done with the command submission on success. For DM direct submissions the DM will need to manage the enter/exit sequencing manually. We cannot invoke a DMCUB command directly within the DM execution helper or we can deadlock.

2024-06-05drm/amd/display: Add null checks for 'stream' and 'plane' before dereferencingSrinivasan Shanmugam1-0/+3
This commit adds null checks for the 'stream' and 'plane' variables in the dcn30_apply_idle_power_optimizations function. These variables were previously assumed to be null at line 922, but they were used later in the code without checking if they were null. This could potentially lead to a null pointer dereference, which would cause a crash. The null checks ensure that 'stream' and 'plane' are not null before they are used, preventing potential crashes.

Since stream pointers are shared between current and new dc_states, updating parameters of one stream will update the other as well which causes unexpected behaviors (i.e., checking that fpo_in_use isn't set in previous state and set in the new state is invalid).

2024-06-05drm/amd/display: Only program P-State force if pipe config changedAlvin Lee1-1/+17
[Description] Today for MED update type we do not call update clocks. However, for FPO the assumption is that update clocks should be called to disable P-State switch before any HW programming since FPO in FW and driver are not synchronized. This causes an issue where on a MED update, an FPO P-State switch could be taking place, then driver forces P-State disallow in the below code and prevents FPO from completing the sequence. In this case we add a check to avoid re-programming (and thus re-setting) the P-State force register by only reprogramming if the pipe was not previously Subvp or FPO. The assumption is that the P-State force register should be programmed correctly the first time SubVP / FPO was enabled, so there's no need to update / reset it if the pipe config has never exited SubVP / FPO.

[Why] The values calculated in optc1_get_otg_active_size are assigned to the wrong output parameters, vertical blank is being used for horizontal size and vice versa. This results in DPG test pattern looking wrong during hardware init, as the DPG dimensions get assigned from this output, and potentially other issues.
