drm/amd/display: Add NULL check for 'afb' before dereferencing in amdgpu_dm_plane_handle_cursor_update This commit adds a null check for the 'afb' variable in the amdgpu_dm_plane_handle_cursor_update function. Previously, 'afb' was assumed to be null, but was used later in the code without a null check. This could potentially lead to a null pointer dereference.

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.

[Description] Refactor code and move fpo_in_use into stream_status to avoid unexpected changes to previous dc_state (i.e., current_state). 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). To avoid incorrect updates to current_state, move the fpo_in_use flag into dc_stream_status since stream_status is owned by dc and are not shared between different dc_states. Reviewed-by:

[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.
