Subject: [PATCH] drm/vc4: Free hang state before destroying BO cache.
|
||
|
|
|
||
|
|
The BO cache will complain if BOs are still allocated when we try to
|
||
|
|
destroy it (since freeing those BOs would try to hit the cache). You
|
||
|
|
could hit this if you were to unload the module after a GPU hang.
|
||
|
|
|
