2024-06-14drm/amd/display: Explicitly cast v_total to signed in a subtractionAlex Hung1-2/+2
[WHY & HOW] v_total is an uint32_t and subtracting an unsigned to a signed will result in an unsigned which is always >= 0. As a result, the ternary conditions are always true and thus has no effect. This is fixed by casting v_total to signed explicitly. This also avoids v_total subtraction to overflow. This fixes 1 NO_EFFECT, 2 DEADCODE and 2 INTEGER_OVERFLOW issues reported by Coverity.

2024-06-14drm/amd/display: Disable DMCUB timeout for DCN35Nicholas Kazlauskas1-0/+1
[Why] DMCUB can intermittently take longer than expected to process commands. Old ASIC policy was to continue while logging a diagnostic error - which works fine for ASIC without IPS, but with IPS this could lead to a race condition where we attempt to access DCN state while it's inaccessible, leading to a system hang when the NIU port is not disabled or register accesses that timeout and the display configuration in an undefined state. [How] We need to investigate why these accesses take longer than expected, but for now we should disable the timeout on DCN35 to avoid this race condition. Since the waits happen only at lower interrupt levels the risk of taking too long at higher IRQ and causing a system watchdog timeout are minimal.

2024-06-14drm/amd/display: reduce ODM slice count to initial new dc state only when neededWenjing Liu2-41/+71
[why] We need to decrease ODM slice when adding or removing planes because MPO support takes precedence over dynamic ODM combine. However there is a case where we remove ODM combine even for ODM combine required timing in the initial new dc state. This is normally okay because ODM will be added back after we pass DML bandwidth validation. However since we remove ODM combine in the initial new state, the previous ODM pipe allocation is lost. This may cause the new plane to take away the original secondary OPP head pipe that is still required in the new state. For a timing that requires ODM 2:1 but optimized with ODM 4:1, if we add an MPO plane, we will not have enough pipe to preserve ODM 4:1. In this case we should reduce ODM slice count then try to add the MPO plane again. By reducing, we are gradually remove 1 ODM slice from right most side one at a time until we have enough free pipes for the new plane. If we remove ODM combine entirely, we could use the pipe at ODM slice index 1 as a DPP pipe for the new plane. But ODM slice 1 is still needed as the timing requires ODM 2:1. This transition is not seamless and user will see corruption on the screen. [how] Remove single ODM slice one at time until we have enough pipes for a new plane.
