Subject: [v8 0/2] Enable Plane Input CSC for ICL
Date: Fri, 2 Nov 2018 00:03:10 +0530 [thread overview]
Message-ID: <1541097192-12300-1-git-send-email-uma.shankar@intel.com> (raw)
This patch series enables plane input csc feature for
ICL. This is needed for YUV to RGB conversion on bottom
3 planes on ICL, other planes are handled in the legacy
way using fixed function hardware.
This series enables color conversion for Full Range YUV data,
limited range handling will be done as a separate patch.
v2: Separated the patch into 2 parts as per Maarten's comments.
Addressed Ville and Maarten's review comment.
v3: Redesigned the register macro definition as per Matt's comment.
Addressed Maarten's review comment.
v4: Added support for Limited Range Color Handling.
v5: Fixed Matt and Maarten's review comments.
v6: Added human readable matrix values for YUV to RGB Conversion along
with just the bspec register values, as per Matt's suggestion.
v7: Refactored the code, move csc coefficient programming function to
intel_sprite.c and made it static as per Ville's review comment.
v8: Addressed Ville's review comment. Called the coefficient programming
from within the skl_program_plane and used I915_WRITE_FW instead of
I915_WRITE.
This has been verified and tested by Maarten and the change is working
as expected.
