Last week's Vulkan 1.0.46 update added a new extension and it's now supported by Mesa's Intel ANV and Radeon RADV drivers.

The extension introduced last week was VK_KHR_incremental_present and is basically about getting only modified regions of an image to present, basically tracking damage and only needing to deal with the updated portions rather than the entire image each time. Thanks to work led by Intel's Jason Ekstrand, the ANV driver picked it up and followed immediately by RADV with the changes being to the common driver-independent code within the Vulkan WSI area.

After a few patches yesterday, if pulling the latest Git, this is another extension supported by these open-source Mesa Vulkan drivers. Great to see the open-source Vulkan drivers keeping up and will be interesting to see what more lands before the Mesa 17.1 branching later this month.
