[v9 0/5] Add support for Gen 11 pipe color features

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch series adds support for Gen11 pipe degamma, CSC
and gamma hardware blocks.

CRC checks are not working for 10bit gamma but works for 8bit
pallete modes which seems to be due to some rounding errors in
pipe. Also there is a corner case where Lut precision is increased
to 3.16, hence its not possible to accurately represent 1.0 which
will require 17 bits. Support for extending the ABI is already in
discussion in below series:

ToDo: Support for Multi Segmented Gamma will be added later.

v2: Addressed Maarten's review comments and re-ordered the patch
series.

v3: Addressed Matt's review comments. Removed rmw patterns
as suggested by Matt.

v4: Addressed Matt's review comments.

v5: Addressed Matt's, Ville and Jani Nikula's review comments.

v6: Addressed Matt and Ville's review comments. Extended GLK 
degamma function and merged ICL degamma support to that. Handled
pipe output csc separately along with regular pipe csc. Dropped
gamma_mode removal patch as Ville is using that to refactor the
gamma handling. This series may need a rebase on top of Ville's
below series:
https://patchwork.freedesktop.org/series/55081/. 

v7: Rebased the series on top of Ville's color management
cleanup and state refactoring series. Addressed Matt's review
comments and aligned state handling as per atomic design.

v8: Fixed macro alignment and some checkpatch warnings.

v9: Fix Maarten's review comments and added his RB tag.
