Subject: drm/nv50: initialize ramht_refs list for faked 0 channel
|
|
|
|
From: Marcin Slusarz <marcin.slusarz@gmail.com>
|
|
|
|
commit 615661f3948a066fd22a36fe8ea0c528b75ee373 upstream.
|
|
|
|
We need it for PFIFO_INTR_CACHE_ERROR interrupt handling,
|
|
because nouveau_fifo_swmthd looks for matching gpuobj in
|
|
ramht_refs list.
|
|
It fixes kernel panic in nouveau_gpuobj_ref_find.
