From 1d5ac0a462ac8c7f41e1e1adb1fc5a7db6038d17 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Tue, 15 Nov 2016 15:25:55 -0800 Subject: [PATCH] anv: Set up binding tables and surface states for input attachments This commit adds the last remaining bits to support input attachments in the Intel Vulkan driver. For color and depth attachments, we allocate an input attachment surface state during vkCmdBeginRenderPass like we do for the render target surface states. This is so that we can incorporate the clear color and aux information as used in rendering. For stencil, we just treat it like a regular texture because we don't there is no aux. Also, only having to worry about at most one input attachment surface for each attachment makes some of the vkCmdBeginRenderPass code simpler.
