Intel Vulkan Linux Driver Now Has Patches For Fast Clears

Building off the input attachments work earlier this week for the Intel open-source Vulkan driver (covered in More Intel ANV Vulkan Code Hits Mesa Git, Other Patches Pending), there are now patches up for review to implement support for fast clears.

Jason Ekstrand at the Intel Open-Source Technology Center who has been leading the "ANV" Vulkan driver effort wrote this Saturday, "This little series builds on top of the input attachment series I sent out earlier this week and adds support for fast clears in Vulkan. I've tested it on both Sky Lake and Haswell and it has no regressions over the input attachments series."

So fast clears are there, great to see it's supported back to Haswell compared to some ANV Vulkan driver features being enabled (at least initially) just for Skylake and newer.

The patches don't comment on any performance changes as a result of the fast clears support, but at Phoronix there will be some fresh Intel Vulkan Linux benchmarks coming up shortly. Those wanting to test the patches that apply against the outstanding input-attachments work can find them on Mesa-dev.
