drm/amd/display: Enable building new display engine with KCOV enabled

2022-07-18T20:42:38Z

The new display engine uses floating point math, which is not supported by KCOV. Commit 9d1d02ff3678 ("drm/amd/display: Don't build DCN1 when kcov is enabled") tried to work around the problem by disabling CONFIG_DRM_AMD_DC_DCN if KCOV_INSTRUMENT_ALL and KCOV_ENABLE_COMPARISONS are enabled. The result is that KCOV can not be enabled on systems which require this display engine. A much simpler and less invasive solution is to disable KCOV selectively when compiling the display enagine while keeping it enabled for the rest of the kernel.

drm/amd/display: fix 32 bit compilation errors in dc_dmub_srv.c

2022-07-08T16:02:08Z

There are several things wrong here. First, none of these numbers are FP, so there is no need to cast to double. Next make sure to use proper 64 bit division helpers. Fixes: 85f4bc0c333c ("drm/amd/display: Add SubVP required code") Reviewed-by: Harry Wentland Signed-off-by: Alex Deucher

drm/amd/display: Add SubVP required code

2022-07-05T20:10:38Z

This commit enables the SubVP feature. To achieve that, we need to: - Don't force p-state disallow on SubVP (can't block dummy p-state) - Send calculated watermark to DMCUB for SubVP - Adjust CAB mode message to PMFW - Add a proper locking sequence for SubVP - Various fixes to SubVP static analysis and determining SubVP config - Currently SubVP not supported with pipe split so merge all pipes before setting up SubVp Reviewed-by: Jun Lei Acked-by: Rodrigo Siqueira Acked-by: Alan Liu Signed-off-by: Alvin Lee Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

[Why & How] CONFIG_DRM_AMD_DC_DCN is used by pass the compilation failures, but DC code should be OS-agnostic. This patch fixes it by removing unnecessasry CONFIG_DRM_AMD_DC_DCN in dc and dc/core directories.

drm/amd/display: move calcs folder into DML

2022-01-18T22:43:36Z

The calcs folder has FPU code on it, which should be isolated inside the DML folder as per https://patchwork.freedesktop.org/series/93042/. This commit aims single-handedly to correct the location of such FPU code and does not refactor any functions. Changes since v2: - Corrected problems to compile when DCN was disabled.
