Hi all,
After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:
drivers/gpu/drm/amd/amdgpu/amdgpu_preempt_mgr.c: In function 'amdgpu_preempt_mgr_new':
drivers/gpu/drm/amd/amdgpu/amdgpu_preempt_mgr.c:75:5: error: 'struct ttm_resource' has no member named 'mm_node'
75 | mem->mm_node = NULL;

drivers/gpu/drm/amd/amdgpu/amdgpu_preempt_mgr.c:129:11: note: (near initialization for 'amdgpu_preempt_mgr_func.alloc')
Caused by commit
cb1c81467af3 ("drm/ttm: flip the switch for driver allocated resources v2")
from the drm-misc tree interacting with commit
b453e42a6e8b ("drm/amdgpu: Add new placement for preemptible SG BOs")
from the drm tree.
I don't know how to fix this, so I added the following hack (a better
fix would be nice):
