From 527652629dc6e7dc593e16505e4b6b648b1f09cc Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Wed, 17 Feb 2016 21:43:40 +0100 Subject: [PATCH] nvc0: add a new validation state for 3D driver constbuf This will be used to invalidate 3D driver constbuf when using COMPUTE and vice-versa. This is needed because this CB contains a bunch of useful information like the addrs of shader buffers.
