            Bug ID: 97579
           Summary: Advertised VkMemoryType is inaccessible on non-LLC
                    chipsets
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Vulkan/intel
          Assignee: intel-3d-bugs at lists.freedesktop.org

On non-LLC chipsets, vkGetPhysicalDeviceMemoryProperties [1] advertises two
memory types: (0) coherent, uncached and (1) incoherent, cached. But
vkGetImageMemoryRequirements [2] and vkGetBufferMemoryRequirements always
report that memory type 0 is required. You can never use memory type 1.
