drm/amd/display: fixup DML dependencies

2020-02-24T07:34:48+00:00

[ Upstream commit 34ad0230062c39cdcba564d16d122c0fb467a7d6 ]

[why]
Need to fix DML portability issues to enable SW unit testing around DML

[how]
Move calcs into dc include folder since multiple components reference it
Remove relative paths to external dependencies

drm/amd/display: readd -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines

2019-10-01T06:26:00+00:00

[ Upstream commit 0f0727d971f6fdf8f1077180d495ddb9928f0c8b ]

arch/x86/Makefile disables SSE and SSE2 for the whole kernel.  The
AMDGPU drivers modified in this patch re-enable SSE but not SSE2.  Turn
on SSE2 to support emitting double precision floating point instructions
rather than calls to non-existent (usually available from gcc_s or
compiler_rt) floating point helper routines for Clang.

This was originally landed in:
commit 10117450735c ("drm/amd/display: add -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines")
but reverted in:
commit 193392ed9f69 ("Revert "drm/amd/display: add -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines"")
due to bugreports from GCC builds. Add guards to only do so for Clang.

drm/amd/display: fix use of uninitialized memory

2018-07-05T21:38:37+00:00

DML does not calculate chroma values for RQ when surface is not YUV, but DC
will unconditionally use the uninitialized values for HW programming.
This does not cause visual corruption since HW will ignore garbage chroma
values when surface is not YUV, but causes presubmission tests to fail
golden value comparison.
