From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Cool, you're going to have to enable Sea Islands (CIK) support for amdgpu. You should just have to add
radeon.cik_support=0 amdgpu.cik_support=1to your kernel parameters. You're probably using GRUB so to do that you'll need to runsudo nano /etc/default/grubto edit it's config file, then add the above to the end ofGRUB_CMDLINE_LINUX_DEFAULT(keep it in the quotes, but space seperated from the previous parameter). Then reboot and hopefully Vulkan works!Alternatively, there's a section on the Arch Wiki for this, it should work fine for Mint too: https://wiki.archlinux.org/title/AMDGPU
Did I do it correctly?
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.cik_support=0 amdgpu.cik_support=1"After saving, is there anything else I have to do it get it to work?Oh whoops yeah there is, run
sudo update-grub.But otherwise that config looks correct.
Ok, do I need to restart my computer now?
Yep!
Ok, it seems to have worked as the game I was using for testing seems to be working fine.
Although, I keep getting the error message
(WARNING: radv is not a conformant Vulkan implementation, testing use only.), is that to be expected?Epic!
I've never seen that on modern AMD stuff that uses radv, but I'm sure it's probably fine.
I had that warning too with a r9 270x and if I remember correctly it was because radv didn't have official/full support for GCN =<2, so what they're saying is something in the line of... it may break. In my case, it worked beautifully gaming with proton, etc.
Did you manage?
Yeah it seems like it's working now.
