Subject: [PATCH 20/24] drm/amd/display: Relax frame size limit for dcn5/6 DML core funcs files
Date: Tue, 11 Aug 2026 05:28:54 +0800 [thread overview]
Message-ID: <20260810213010.1703162-21-PingLei.Lin@amd.com> (raw)
In-Reply-To: <20260810213010.1703162-1-PingLei.Lin@amd.com>
From: Ivan Lipski <ivan.lipski@amd.com>
[Why]
During compilation with allmodconfig with KASAN, there appears a Werror:
dml2_core_dcn5_funcs_mode_programming.c:11:13: error: stack frame size
(2400) exceeds limit (2048) in 'dcn5_mode_programming'
[-Werror,-Wframe-larger-than]
The dcn5/dcn6 dml2_core_*_funcs_mode_{programming,support} files were
split out of dml2_core_dcn4_calcs.o, which carries a relaxed
-Wframe-larger-than limit via $(frame_warn_flag) (2056 normally, or
4096 for clang + KASAN/KCSAN + COMPILE_TEST). The split-out files were
never added to the per-file CFLAGS override list, so they inherited the
strict global default of 2048. This is why these files trip the frame
size warning under KASAN while the larger dml2_core_dcn4_calcs.o does
not.
[How]
Apply the same $(frame_warn_flag) and CFLAGS_REMOVE handling used for
dml2_core_dcn4_calcs.o to the split-out files:
- dml2_core_dcn5_funcs_mode_programming.o
- dml2_core_dcn5_funcs_mode_support.o
- dml2_core_dcn6_funcs_mode_programming.o
- dml2_core_dcn6_funcs_mode_support.o
