Phoronix: AMDVLK Open-Source Radeon Driver Arrives With Vulkan 1.1 Support

When writing about the big Vulkan 1.1 release a few days ago I was wondering myself whether the official AMDVLK Vulkan driver or RADV Mesa-based Vulkan driver would be first to the table with Vulkan 1.1 patches... It turns out AMDVLK won this round, at least by a small measure of time...

Could someone please briefly describe again how to switch between radv and amdvlk per application?

[shmerl]

Is there some effort to package amdvlk in Debian and other distros?

You can run any application with:

VK_ICD_FILENAMES=/path-to-your-icd/<some_icd>.json application

That will load needed driver defined in ICD JSON config.

I suppose there must be some system wide override like that that sets the default driver if you have multiple installed.

They haven't made a release yet have they? So is it good enough to be available outside of dev packages (which is at least the case in Arch)?

You mean it's still development quality? I thought it has been considered released for a while already.

Thanks!
On my system (Arch), it's
/usr/share/vulkan/icd.d/radeon_icd.x86_64.json (radv)
/usr/share/vulkan/icd.d/amd_icd64.json (amdvlk)

Sorry for being late, I was waiting for Intel to publish their patches as we depend on them, but RADV is very much conformant for 1.1 with the published patches:

Mini-benchmark in SS Fusion: RadV is still ~10% faster than amdvlk/Linux, and amdvlk/Windows is still ~15% faster than radv (GPU limit).
However, radv is slightly faster than amdvlk/Windows in CPU-limit, roughly 5%.

Good to see compliance submission for recent cards with radv. Do you plan to cover more than just a few?
