Subject: [PATCH 0740/1085] drm: vc4: Free the dlist alloc immediately if it
|
|
never hit the hw
|
|
|
|
atomic_check creates a state, and allocates the dlist memory for
|
|
it such that atomic_flush can not fail.
|
|
|
|
On destroy that dlist allocation was being put in the stale list,
|
|
even though it had never been programmed into the hardware,
|
|
therefore doing lots of atomic_checks could consume all the dlist
|
|
memory and fail.
|
|
|
|
If the dlist has never been programmed into the hardware, then
|
|
free it immediately.
