Ah yes, bringing the joy of frame-larger-than warnings to RISC-V:
../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_32.c:58:13: warning: stack frame size (2416) exceeds limit (2048) in 'DISPCLKDPPCLKDCFCLKDeepSleepPrefetchParametersWatermarksAndPerformanceCalculation' [-Wframe-larger-than]

Nathan, have you given up on these being sorted out?

Also, what on earth is that function name, it exceeds 80 characters
before even considering anything else? Actually, I don't think I want
to know.
