From 9628631a380ff24630bf97b982df07b4e7e2a79f Mon Sep 17 00:00:00 2001 From: Lionel Landwerlin Date: Sat, 27 Apr 2019 11:35:32 +0800 Subject: [PATCH] Revert "anv: limit URB reconfigurations when using blorp" In commit 0d46e404 ("anv: limit URB reconfigurations when using blorp") we tried to limit the number of URB reconfiguration by checking if the last allocation is large enough to fit the blorp dispatch. We used the last bound pipeline to compare the allocation. The problem with this is that the pipeline is bound but its commands might not have been emitted into the command buffer yet. Let's just revert commit 0d46e404677264bfb12ada15290e39c10a5eb455 since it didn't seem to yield any performance improvement.
