From: Paul Kocialkowski
Date: Thu Apr 25 2019 - 08:29:47 EST


Changes since v6:
* Removed vc4_v3d_bin_bo_put from error paths;
* Added WARN_ON_ONCE when no bin BO at refcount release.

Changes since v5:
* Fix more locking mistakes;
* Introduce get/put helpers;
* Grabbed a reference when submitting an exec job with a binner slot.
* Addressed misc comments.

Changes since v4:
* Used a kref on the binner bo instead of firstopen/lastclose;
* Added a mutex to prevent race conditions;
* Took care of enabling the OOM interrupt when we have a binner BO allocated.

Changes since v3:
* Split changes into more commits when possible;
* Reworked binner bo alloc condition as discussed.

Changes since v2:
* Removed deprecated sentence about fristopen;
* Added collected Reviewed-By tags.

Changes since v1:
* Squashed the two final patches into one.
