Author: Kenneth Graunke <[email protected]> Date: Thu Sep 29 11:53:17 2016 -0700 anv: Clamp depth buffer dimensions to be at least 1. When there are no framebuffer attachments, fb->width and fb->height will be 0. Subtracting 1 results in 4294967295 which is too large for the field, causing genxml assertions when trying to create the packet. In this case, we can just program it to 1.
