drm/amd/display: Do not add '-mhard-float' to dml_ccflags for clang

2023-01-26T03:43:11+00:00

When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, it warns: clang-16: error: argument unused during compilation: '-mhard-float' [-Werror,-Wunused-command-line-argument] Similar to commit 84edc2eff827 ("selftest/fpu: avoid clang warning"), just add this flag to GCC builds. Commit 0f0727d971f6 ("drm/amd/display: readd -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines") added '-msse2' to prevent clang from emitting software floating point routines.

drm/amd/display: add DCN support for ARM64

2022-11-04T20:05:54+00:00

After moving all FPU code to the DML folder, we can enable DCN support for the ARM64 platform. Remove the -mgeneral-regs-only CFLAG from the code in the DML folder that needs to use hardware FPU, and add a control mechanism for ARM Neon.

drm/amd/display: Increase frame size limit for display_mode_vba_util_32.o

2022-10-17T21:41:21+00:00

Building 32-bit images may fail with the following error. drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_util_32.c: In function ‘dml32_UseMinimumDCFCLK’: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_util_32.c:3142:1: error: the frame size of 1096 bytes is larger than 1024 bytes This is seen when building i386:allmodconfig with any of the following compilers. gcc (Debian 12.2.0-3) 12.2.0 gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0 The problem is not seen if the compiler supports GCC_PLUGIN_LATENT_ENTROPY because in that case CONFIG_FRAME_WARN is already set to 2048 even for 32-bit builds. dml32_UseMinimumDCFCLK() was introduced with commit dda4fb85e433 ("drm/amd/display: DML changes for DCN32/321"). It declares a large number of local variables. Increase the frame size for the affected file to 2048, similar to other files in the same directory, to enable 32-bit build tests with affected compilers.

Makefile.compiler: replace cc-ifversion with compiler-specific macros

cc-ifversion is GCC specific. Replace it with compiler specific variants. Update the users of cc-ifversion to use these new macros.

DCN314 has multiple references to FPU operations inside the resource files, and we need to move those codes to the DML folder. This commit creates the dcn314_fpu files and moves the bounding box operation to this file.

drm/amd/display: remove DML Makefile duplicate lines

2022-08-10T18:57:36+00:00

There are two identical CFLAGS entries for "display_mode_vba_20.o", so remove one of them. Also, as there's already an entry for "display_mode_lib.o" CFLAGS, regardless of CONFIG_DRM_AMD_DC_DCN being defined or not, remove the one entry between CONFIG_DRM_AMD_DC_DCN ifdef guards.

We are working to isolate FPU operations inside the DML folder, and the file dcn32_clk_mgr has some of these operations. This commit moves the FPU operations inside the clock manager and creates the dcn32_fpu file to aggregate those operations. Note that there is no functional change ere, just moving code from one part to another.
