-Subject: [PATCH] drm/vc4: Fix overflow mem unreferencing when the binner runs
- dry.
-
-Overflow memory handling is tricky: While it's still referenced by the
-BPO registers, we want to keep it from being freed.  When we are
-putting a new set of overflow memory in the registers, we need to
-assign the old one to the last rendering job using it.
-
-We were looking at "what's currently running in the binner", but since
-the bin/render submission split, we may end up with the binner
-completing and having no new job while the renderer is still
-processing.  So, if we don't find a bin job at all, look at the
-highest-seqno (last) render job to attach our overflow to.
