A pretty good milestone has been achieved with the open source Vulkan driver for AMD that Dave Airlie has been working on with Bas Nieuwenhuizen. It can now run Dota 2.
Over a month ago I let people know about a new Vulkan driver being worked on for AMD graphics cards, and it's pleasing to see such amazing progress.
Dave notes it is only currently working on VI AMD GPUs, as there is an issue with Polaris they need to track down.
He also notes that The Talos Principle is mostly working, but still has some black areas so they have work to do there.
See the blog post here for the full info.
Will be great to see this continue to progress, great work!
You can find the current code here on github if interested to check it out.

QuoteWell this morning I finally found the last bug that was causing missing rendering on Dota 2. We were missing support for a compressed texture format that dota2 used. So currently dota 2 renders, I've no great performance comparison to post yet because my CPU is 5 years old, and can barely get close to 30fps with GL or Vulkan. I think we know of a couple of places that could be bottlenecking us on the CPU side. The radv driver is currently missing hyper-z (90% done), fast color clears and DCC, which are all GPU side speedups in theory. Also running the phoronix-test-suite dota2 tests works sometimes, hangs in a thread lock sometimes, or crashes sometimes. I think we have some memory corruption somewhere that it collides with.

It is amazing how fast radv is coming along but also not surprising, both Dave and Bas are very experienced with Mesa and AMD hardware as both of them have done lots of work on RadeonSI.
It will be interesting to see what AMD do going forward. If radv is feature complete in the next few months, will AMD still open source their proprietary Vulkan driver or just pile in and work on radv and drop the proprietary driver? Will be interesting to see.

Honestly, if they keep going and get it complete enough, I think AMD will just use this instead as it's quicker and easier for them. I mean, what else is AMD to do? Their code can't be much more than this when it's complete, since Vulkan takes a lot out of the driver and this is already open source.

Yep, been very impressed with how fast they've put together the radv driver. With the uncertainty of how long it would be for AMD to open source their Vulkan driver (and the possibility they couldn't fully because of IP).. This is awesome news for those of us with AMD graphics.
Unfortunately I don't think *my* GPU is supported in the AMDGPU kernel though, so I haven't tried it out yet. Hopefully that won't be much longer.
We just need the Freesync stuff to land and I'm hoping they open source WattMan.

Good news, The freesync stiff is in the DAL code which is likely kernel 4.9 lejimster.
Their work on the AMDGPU driver has been quite rapid given their work load. Been using it now on my 290x for a month or so without issue. Hell, mesa 12 + AMDGPU driver runs ARMA3 rather well.

Good news. But last Dota major update killed my Vulkan, but I am on nvidia prop. Now I have much higher load on my poor laptop again. :><:
