From ac0ca066de654fd80a6f18c9c32555d7d91c0335 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Mon, 17 Oct 2016 09:14:48 -0700 Subject: anv/cmd_buffer: Move state base address re-emit into ExecuteCommands This has two primary advantages. First, it means that the batch_chain code knows less about the actual command buffer contents which is good because improves separation. Second, it means that it only gets re-emitted once after all of the secondaries instead of once after each secondary which is just wasteful. It also has the advantage of cleaning the code up a bit.
