Introduced earlier this month as part of landed the initial implementation for RADV in Mesa 19.0. "A simple Vulkan extension that allows apps to query size and usage of all exposed memory heaps."

Other work has included the revised VK_EXT_pci_bus_info, variable pointers, VK_EXT_scalar_block_layout, various GFX9/Vega optimizations, and a lot of low-level code improvements.
