From e8ea42d245cb6adc7f16ee4e96fd89d905d2163a Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 17 May 2017 13:22:39 -0700 Subject: [PATCH] vc4: Don't allocate new BOs to avoid synchronization when they're shared. If X11 did a software fallback to the entire screen, we would throw out the BO the screen is scanning out from and allocate a new one.
