From: "Leo (Sunpeng) Li" <sunpeng.li@xxxxxxx> DCN1 contains code that utilizes fp math. When CONFIG_KCOV_INSTRUMENT_ALL and CONFIG_KCOV_ENABLE_COMPARISONS are enabled, build errors are found. See this earlier patch for details: https://lists.freedesktop.org/archives/dri-devel/2018-August/186131.html As a short term solution, disable CONFIG_DRM_AMD_DC_DCN1_0 when KCOV_INSTRUMENT_ALL and KCOV_ENABLE_COMPARISONS are enabled. In addition, make it a fully derived config, taking into account CONFIG_X86.
