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

2019-10-01T06:24:45Z

commit 0f0727d971f6fdf8f1077180d495ddb9928f0c8b upstream. 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 incorrect DML output_bpp value

2019-06-22T14:34:13Z

[Why] The output_bpp pipe parameter was assigned an incorrect value (color depth enum), and subsequently used to overwrite the OutputBpp parameter calculated by DML. Seems like this had no effect except with DSC enabled, which would make DML produce bad outputs. [How] Removed assignment to OutputBpp, fixed output_bpp assignment, and properly set ForcedOutputLinkBPP instead of OutputBpp. Also removed condition in DML that prevented forcing of Output BPP with DSC enabled.

drm/amd/display: Properly guard display_mode_vba with DCN2

2019-06-22T14:34:09Z

[Why] display_mode_vba is for DCN2 and up. When building for upstream (DCN1 enabled only), there will be a build error, since display_mode_vba.c/h is stripped out. Note that building DCN1 only with internal dal-dev is still fine, since display_mode_vba.h is not stripped out internally - only in upstream. The make directives therefore stll work, and so will any #include's. [How] Since subsequent generations require DCN2 enabled anyways, guard the makefile directive for display_mode_vba.o with DCN2. Guard any includes with DCN2. In addition, guard the entire contents of display_mode_vba.h with DCN2, to simulate the file being stripped out in upstream. A forward declaration for 'struct display_mode_lib' also needs to be added in display_mode_lib.h. Previously, display_mode_vba.h contained the forward declaration, and display_mode_lib.h in turn included it. This won't work if mode_vba.h is stripped out, requring mode_lib.h to do so itself.
