Nathan Chancellor b0f4b23fc3 drm/amd/display: Mark dml30's UseMinimumDCFCLK() as noinline for stack usage ... This function consumes a lot of stack space and it blows up the size of dml30_ModeSupportAndSystemConfigurationFull() with clang: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3542:6: error: stack frame size (2200) exceeds limit (2048) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than] void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib) ^ 1 error generated. Commit a0f7e7f759 ("drm/amd/display: fix i386 frame size warning") aimed to address this for i386 but it did not help x86_64. To reduce the amount of stack space that dml30_ModeSupportAndSystemConfigurationFull() uses, mark UseMinimumDCFCLK() as noinline, using the _for_stack variant for documentation. While this will increase the total amount of stack usage between the two functions (1632 and 1304 bytes respectively), it will make sure both stay below the limit of 2048 bytes for these files. The aforementioned change does help reduce UseMinimumDCFCLK()'s stack usage so it should not be reverted in favor of this change.
