This commit is the last part of the fix that reduces the stack size in
the DML2 code.
That does not really help when trying to build allmodconfig or allyesconfig
with gcc 11.4 or 12.3.
drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c: In function 'dml_prefetch_check':
drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6707:1: error: the frame size of 2056 bytes is larger than 2048 bytes
This is with v6.6-14500-g1c41041124bd.
I am overwriting it by forcing CONFIG_FRAME_WARN=0 in my test builds for
x86_64, but of course that affects all code. Maybe consider increasing
frame-larger-than in drivers/gpu/drm/amd/display/dc/dml2/Makefile ?
That has been done as of the following patch:
https://patchwork.freedesktop.org/patch/565675/
Currently it is
ifneq ($(CONFIG_FRAME_WARN),0)
frame_warn_flag := -Wframe-larger-than=2048
endif
