[Mesa-dev] [PATCH 11/16] vulkan/wsi: Add modifiers support to wsi_create_native_image
Jason Ekstrand

Fri Feb 9 23:43:27 UTC 2018
This involves extending our fake extension a bit to allow for additional
querying and passing of modifier information. The added bits are
intended to look a lot like the draft of VK_EXT_image_drm_format_modifier.
Once the extension gets finalized, we'll simply transition all of the
structs used in wsi_common to the real extension structs.
