From cb71ae5572a16a974e3f60ad66fcae329c85961a Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Sat, 14 Sep 2019 11:23:51 +0200 Subject: [PATCH] panfrost: Stop using panfrost_bo_release() outside of pan_bo.c panfrost_bo_unreference() should be used instead. The only difference caused by this change is that the scratchpad, tiler_heap and tiler_dummy BOs are now returned to the cache instead of being freed when a context is destroyed. This is only a problem if we care about context isolation, which apparently is not the case since transient BOs are already returned to the per-FD cache (and all contexts share the same address space anyway, so enforcing context isolation is almost impossible).
