From 342c811646c0d12256b2a0b0d8ddf70f7fbdfcf7 Mon Sep 17 00:00:00 2001 From: Chad Versace Date: Thu, 2 Nov 2017 16:55:55 -0700 Subject: [PATCH] anv: Refactor get_buffer_format_properties() Make it a stand-alone function. Pre-patch, for some formats the function returned incorrect VkFormatFeatureFlags which were cleaned up by the caller. This prepares for a cleaner implementation of VK_EXT_image_drm_format_modifier.
