Phoronix: RADV Is Now Effectively Conformant For Vega GPUs With Vulkan 1.0

Since October RADV has officially become a Vulkan 1.0 conformant driver for Volcanic Islands GPUs while Sea Islands and Polaris hardware has also been on this same support level. RADV support for the newer Vega GPUs had been lagging behind, but these latest-generation AMD GPUs are now also effectively conformant...

The end of the year is definitely exciting!

Good work and thanks to airlied and BNieuwenhuizen !

Can radv run Asynchronous Compute (graphics + compute queues in parallel in the same shader unit)?

If it's conformant for Polaris, why do I see this in vulkaninfo (current Mesa master, RX 480):

WARNING: radv is not a conformant vulkan implementation, testing use only.

Note the warning in the end.

Note the warning in the end.

Note the sentence before the image in the article:

But Vega on RADV isn't yet officially in compliance as David Airlie has yet to fill out the paperwork and get the results approved by The Khronos Group. Airlie should be tackling those Vega compliance steps in 2018.

The news is that the driver is effectively in compliance, so it passes the tests or something, but it has not been officialized.

My question and snippet above was about Polaris, not Vega, so it still stands.

I didn't see any official statement about Polaris being officially conformant though.

Well, the article above says:

What exactly does it mean? That radv for Polaris isn't official, but essentially the same feature wise?

from the linked blog post it seems they submitted the conformance test only for the R9 285

https://airlied.blogspot.it/2017/10/radv-conformant-vulkan-driver-with.html

There are no other cards which were submitted in that list by them.

So I'm guessing this is still "card passing the test but it's not officialized yet".

Posting this issue in the Mesa mailing list will get more answers. Maybe they just forgot to change a flag somehwere to show RADV is conformant for vulkaninfo.
