From d296dea54e243c41c2b3fbe631f7bcb87db6ae8c Mon Sep 17 00:00:00 2001 From: Lionel Landwerlin Date: Wed, 27 Sep 2017 14:16:04 +0100 Subject: [PATCH] anv/cmd_buffer: fix push descriptors with set > 0 When writing to set > 0, we were just wrongly writing to set 0. This commit fixes this by lazily allocating each set as we write to them. We didn't go for having them directly into the command buffer as this would require an additional ~45Kb per command buffer. v2: Allocate push descriptors from system memory rather than in BO streams.
