From caf0f98dc280b5426b1858d4e70130aa3dd9679c Mon Sep 17 00:00:00 2001 From: Hamza Mahfooz Date: Mon, 5 Jun 2023 13:59:08 -0400 Subject: [PATCH] drm/amd/display: mark dml31's UseMinimumDCFCLK() as noinline_for_stack clang reports: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c:3797:6: error: stack frame size (2632) exceeds limit (2048) in 'dml31_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than] 3797 | void dml31_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib) | ^ 1 error generated. So, since UseMinimumDCFCLK() consumes a lot of stack space, mark it as noinline_for_stack to prevent it from blowing up dml31_ModeSupportAndSystemConfigurationFull()'s stack size.
