Hi,
There is a "reproduce" link in the original report. Hope it would be helpful:
reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20231120/202311200955.pmjdQEM1-lkp@intel.com/reproduce)
For a quick check, please kindly try the following steps to reproduce the issue:
$ git checkout v6.8-rc3 $ wget https://download.01.org/0day-ci/archive/20231120/202311200955.pmjdQEM1-lkp@intel.com/config -O .config $ make W=1 LLVM=1 ARCH=x86_64 olddefconfig $ make -j$(nproc) W=1 LLVM=1 ARCH=x86_64 drivers/gpu/drm/amd/amdgpu/ .. drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6710:12: warning: stack frame size (3368) exceeds limit (3072) in 'dml_core_mode_support' [-Wframe-larger-than] dml_bool_t dml_core_mode_support(struct display_mode_lib_st *mode_lib) ^
