From 55ad7e40ee7038b9aaf039a0aee55ac62fcfe170 Mon Sep 17 00:00:00 2001 From: Manasi Navare Date: Fri, 30 Nov 2018 17:04:12 -0800 Subject: [PATCH] drm/i915/dp: Fix link compute m_n calc for DSC MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Fix the intel_link_compute_m_n in case of display stream compression. This patch passes the compressed_bpp to intel_link_compute_m_n if compression is enabled.
