From d2b4a9da038a200db3c5c61a11d5ea451cc6cc98 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Wed, 19 Oct 2016 11:33:55 -0700 Subject: [PATCH] anv: Rework the way render target surfaces are allocated This commit moves the allocation and filling out of surface state from CreateImageView time to BeginRenderPass time. Instead of allocating the render target surface state as part of the image view, we allocate it in the command buffer state at the same time that we set up clears. For secondary command buffers, we allocate memory for the surface states in BeginCommandBuffer but don't fill them out; instead, we use our new SOL-based memcpy function to copy the surface states from the primary command buffer. This allows us to handle secondary command buffers without the user specifying the framebuffer ahead-of-time.
