At this stage, we must have all the FPU code for DCN30 isolated in the DML folder. Drop FPU flags from Makefile. Reviewed-by: Harry Wentland Acked-by: Alex Hung Signed-off-by: Rodrigo Siqueira Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amdgpu/display: make FP handling in Makefiles consistent

Use the same pattern as the DML Makefile and while we are here add a missing x86 guard around the msse flags for DCN3.2.x. Reviewed-by: Harry Wentland Signed-off-by: Alex Deucher

amdgpu: fix clang build warning

2021-01-28T18:40:48Z

clang warns about the -mhard-float command line arguments on architectures that do not support this: clang: error: argument unused during compilation: '-mhard-float' [-Werror,-Wunused-command-line-argument] Move this into the gcc-specific arguments.

drm/amdgpu/display: drop DCN support for aarch64

2021-01-06T21:24:10Z

From Ard: "Simply disabling -mgeneral-regs-only left and right is risky, given that the standard AArch64 ABI permits the use of FP/SIMD registers anywhere, and GCC is known to use SIMD registers for spilling, and may invent other uses of the FP/SIMD register file that have nothing to do with the floating point code in question. Note that putting kernel_neon_begin() and kernel_neon_end() around the code that does use FP is not sufficient here, the problem is in all the other code that may be emitted with references to SIMD registers in it. So the only way to do this properly is to put all floating point code in a separate compilation unit, and only compile that unit with -mgeneral-regs-only." Disable support until the code can be properly refactored to support this properly on aarch64. Acked-by: Will Deacon Reported-by: Ard Biesheuvel Signed-off-by: Alex Deucher
