From 35ca2ad22e20ad3bc3301ee1e9157b8c351d959e Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Thu, 13 Feb 2020 14:46:25 -0600 Subject: [PATCH] anv: Parse VkPhysicalDeviceFeatures2 in CreateDevice The client may enable robustBufferAccess2 via either pCreateInfo->pEnabledFeatures or via a chained-in VkPhysicalDeviceFeatures2 struct. We need to parse both.
