[WHY & HOW] Since the backup and restore for plane and stream states has a significant amount of data to copy, we will change the backup and restore sequence to only take place during full updates. We will also move the scratch memory to struct dc instead of dc_state to avoid needing to allocate large amounts of memory every time we create a new DC state. Reviewed-by:

Wenjing Liu authored
[WHY & HOW] Update planes and stream version 3 separates FULL and FAST updates to their own sequences. It aims to clean up frequent checks for update type resulting unnecessary branching in logic flow. It also adds a new commit minimal transition sequence, which detects the need for minimal transition based on the actual comparison of current and new states instead of "predicting" it based on per feature software policy, i.e. could_mpcc_tree_change_for_active_pipes. The new commit minimal transition sequence is made universal to any power saving features that would use extra free pipes such as Dynamic ODM/MPC Combine, MPO or SubVp. Therefore there is no longer a need to specially handle compatibility problems with transitions among those features as they are now transparent to the new sequence. Reviewed-by:

[WHY] If DCN is in idle then we should not be accessing DCN registers or it can lead to hangs. [HOW] Log the error and return 0 or drop the write if it's in idle. This is skipped in the exit sequence itself since the boolean flips before it starts. It also does not cover accesses from external clients outside of DM/DC like firmware or the kernel mode driver.

Fixes index out of bounds issue in the color transformation function. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds, an error message is logged and the function returns false to indicate an error.

[WHY] Currently 3-tap chroma subsampling is used for YCbCr422/420. When ODM pipesplit is used, pixels on the left edge of ODM slices need one extra pixel from the right edge of the previous slice to calculate the correct chroma value. Without this change, the chroma value is slightly different than expected. This is usually imperceptible visually, but it impacts test pattern CRCs for compliance test automation. [HOW] Update logic to use the register for adding extra left edge pixel for YCbCr422/420 ODM cases.
