From b99493c6288e060e2caded5124e7d347149704db Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Fri, 20 Jul 2018 14:24:17 -0700 Subject: anv: Properly handle GetImageSubresourceLayout on complex images We support mipmapped and arrayed linear images so we need to support vkGetImageSubresourceLayout on them. Fortunately, it's just a trivial call into ISL.
