From 6de01faac5a20208422fb75d22f2bd88c53f53d8 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Fri, 24 Apr 2020 15:15:09 -0700 Subject: [PATCH] freedreno/a6xx: invalidate tex state cache entries on rebind When a resource's backing bo changes, its seqno will be incremented. Which would result in a new tex state cache key, and nothing to clean up the old tex state until the sampler view/state is destroyed. But in some games, that may never happen, or at least not happen before we run out of memory.
