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: https://patchwork.freedesktop.org/patch/249771/ 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/.
