From c33ebdb717e9ffa0e5cae3f75c5f5795102bdc3b Mon Sep 17 00:00:00 2001 From: Vandita Kulkarni Date: Tue, 18 May 2021 17:06:10 -0700 Subject: [PATCH] drm/i915/xelpd: Add rc_qp_table for rcparams calculation Add the qp table for 444 formats, for 8bpc, 10bpc and 12bpc, as given by the VESA C model for DSC 1.1 v2: - Add include guard to header (Jani) - Move the big tables to a .c file (Chris, Jani, Lucas) v3: - Make tables 'static const' and add lookup functions to index into them. (Jani) v3.1: - Include missing .h file.
