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/[email protected]/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/[email protected]/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/

My repro is:

1. Clone and build [0]. If using Manjaro or anything else Arch-based,
you can install llvm-git from AUR.
2. Clone the latest net-next (or mainline or linux-next or whatever).
3. Use some default distro kernel .config -- I'm using Fedora's,
Arch/Manjaro/etc. would also work.
4. make -j$(($(nproc) + 1)) LLVM=/path/to/built/llvm-git/bin/ LLVM_IAS=1
all

I'm facing it again on the latest -rc4 and Clang 19 (the latest master Git):

drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6710:12:
warning: stack frame size (2128) exceeds limit (2048) in

6710 | dml_bool_t dml_core_mode_support(struct display_mode_lib_st
*mode_lib)
| ^
1 warning generated.

Please fix it once and forever somehow, don't abuse the stack =\

Thanks,
Olek
