Subject: [RFC 11/17] drm/amdgpu: DC also loves to allocate stuff where it shouldn't
Date: Tue, 12 May 2020 10:59:38 +0200 [thread overview]
Message-ID: <20200512085944.222637-12-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20200512085944.222637-1-daniel.vetter@ffwll.ch>
Not going to bother with a complete&pretty commit message, just
offending backtrace:
kvmalloc_node+0x47/0x80
dc_create_state+0x1f/0x60 [amdgpu]
dc_commit_state+0xcb/0x9b0 [amdgpu]
amdgpu_dm_atomic_commit_tail+0xd31/0x2010 [amdgpu]
commit_tail+0xa4/0x140 [drm_kms_helper]
drm_atomic_helper_commit+0x152/0x180 [drm_kms_helper]
drm_client_modeset_commit_atomic+0x1ea/0x250 [drm]
drm_client_modeset_commit_locked+0x55/0x190 [drm]
drm_client_modeset_commit+0x24/0x40 [drm]
v2: Found more in DC code, I'm just going to pile them all up.
