2024-05-02drm/amd/display: Avoid -Wenum-float-conversion in ↵Nathan Chancellor1-1/+1
add_margin_and_round_to_dfs_grainularity() When building with clang 19 or newer (which strengthened some of the enum conversion warnings for C), there is a warning (or error with CONFIG_WERROR=y) around doing arithmetic with an enumerated type and a floating point expression. drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_dpmm/dml2_dpmm_dcn4.c:181:58: error: arithmetic between enumeration type 'enum dentist_divider_range' and floating-point type 'double' [-Werror,-Wenum-float-conversion] 181 | divider = (unsigned int)(DFS_DIVIDER_RANGE_SCALE_FACTOR * (vco_freq_khz / clock_khz)); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 error generated. This conversion is expected due to the nature of the enumerated value and definition, so silence the warning by casting the enumeration to an integer explicitly to make it clear to the compiler.

2024-04-27drm/amd/display: Fix CFLAGS for dml2_core_dcn4_calcs.oNathan Chancellor1-2/+2
-Wframe-larger-than=2048 is a part of both CFLAGS and CFLAGS_REMOVE for dml2_core_dcn4_calcs.o, which means that it ultimately gets removed altogether for 64-bit targets, as 2048 is the default FRAME_WARN value for 64-bit platforms, resulting in no -Wframe-larger-than coverage for this file. Remove -Wframe-larger-than from CFLAGS_REMOVE_dml2_core_dcn4_calcs.o and move to $(frame_warn_flag) for CFLAGS_dml2_core_dcn4_calcs.o, as that accounts for the fact that -Wframe-larger-than may need to be larger than 2048 in certain situations, such as when the sanitizers are enabled.

When building with tip of tree Clang, there are some new instances of -Wframe-larger-than from the new display code (which become fatal with CONFIG_WERROR=y): drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_shared.c:754:6: error: stack frame size (2488) exceeds limit (2048) in 'dml2_core_shared_mode_support' [-Werror,-Wframe-larger-than] 754 | bool dml2_core_shared_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params) | ^ drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_shared.c:9834:6: error: stack frame size (2152) exceeds limit (2048) in 'dml2_core_shared_mode_programming' [-Werror,-Wframe-larger-than] 9834 | bool dml2_core_shared_mode_programming(struct dml2_core_calcs_mode_programming_ex *in_out_params) | ^ 2 errors generated. These warnings do not occur when CONFIG_K{A,C,M}SAN are disabled, so add $(frame_warn_flag) to dml2_core_shared.o's CFLAGS, which was added in commit 6740ec97bcdb ("drm/amd/display: Increase frame warning limit with KASAN or KCSAN in dml2") to account for this situation.
