2022-10-24drm/amd/display: Don't return false if no streamAlvin Lee
pipe_ctx[i] exists even if the pipe is not in use. If the pipe is not in use it will always have a null stream, so don't return false in this case.

2022-10-06drm/amd/display: For SubVP pipe split case use min transition into MPOAlvin Lee
[Description] - For SubVP pipe split case we need to use a minimial transition when opening MPO video since we are transitioning from 4 pipes to 3 pipes where an OPP for a previous MPCC will change - Also save and restore mall config when doing fast_validate in case there was a shallow copy of the dc->current_state Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Hamza Mahfooz <hamza.mahfooz@amd.com> Signed-off-by: Alvin Lee <Alvin.Lee2@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-09-19drm/amd/display: Do second pass through DML for DET calculationAlvin Lee
[Why & How] If we find that DML requires pipe split, run through DML again because the DET allocation per pipe must be re-assigned.

2022-09-19drm/amd/display: Fix pipe split predictionAlvin Lee
[Why & How] - Pipe split prediction previously only took into account MPC split. We must also consider when ODM combine is required, and when we apply ODM combine by policy. - Also re-work DET allocation function as it wasn't properly splitting the DET per stream, per plane.

2022-07-25drm/amd/display: Move SubVP functions to dcn32_fpuRodrigo Siqueira
It looks like many of the code related to SubVP uses FPU operation, and we have many static functions that are part of this feature. This commit is a little bit large, but it only moves SubVP operation from one file to another, and I had to do it in a single change due to dependencies between functions.

2022-07-25drm/amd/display: Update de-tile override to anticipate pipe splittingTaimur Hassan
