Hi John,
well, this warning is intentional.
The key point is that your random config results in a very suboptimal situation where the graphics driver only barely work.
And radeon is pointing that out with this warning. That is totally expected behavior.

Hi guys,
This warning in the radeon driver breaks my randconfig build on v5.19-rc2:
drivers/gpu/drm/radeon/radeon_object.c:186:2: error: #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to write-combining [;;https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgcc.gnu.or... inedocs/gcc/Warning-Options.html#index-Wcpp-Werror=cpp;;]
Is anything being done to fix it? I don't see anything in -next or on dridevel list recently which it could be.
thanks, John
