            Bug ID: 102024
           Summary: FORMAT_FEATURE_SAMPLED_IMAGE_BIT not supported for
                    D16_UNORM and D32_SFLOAT
           Product: Mesa
           Version: git
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Vulkan/intel
          Assignee: intel-3d-bugs at lists.freedesktop.org

According to section `32.3.3. Required Format Support` of the Vulkan specs, the
`VK_FORMAT_D32_SFLOAT` and `VK_FORMAT_D16_UNORM` formats must support the
`VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT` usage.

However the driver doesn't report this usage on my Ivy Bridge (Intel Core
i5-3210M).

More generally the driver doesn't report any depth/stencil format that supports
`SAMPLED_IMAGE_BIT`, which makes it a bit limiting for shadowmaps for example.
