Subject: mainline build failure for x86_64 allmodconfig with clang
Date: Thu, 4 Aug 2022 19:36:57 +0100	[thread overview]
Message-ID: <YuwRyQYPCb1FD+mr@debian> (raw)

Hi All,

The latest mainline kernel branch fails to build for x86_64 allmodconfig
with clang. The errors are:

drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3596:6: error: stack frame size (2216) exceeds limit (2048) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than]
void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)

drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c:3908:6: error: stack frame size (2184) exceeds limit (2048) in 'dml31_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than]
void dml31_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)

drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_32.c:1726:6: error: stack frame size (2176) exceeds limit (2048) in 'dml32_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than]
void dml32_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)

git bisect points to 3876a8b5e241 ("drm/amd/display: Enable building new display engine with KCOV enabled").

My last good build for clang was with e2b542100719 ("Merge tag 'flexible-array-transformations-UAPI-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux").

I will be happy to test any patch or provide any extra log if needed.
