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.

How can I get OpenCL to work on Debian Bookworm with an AMD 7900 XTX? (self.linux)

I looked this up before buying the GPU, and I read that it should "just work" on Debian stable (Bookworm, 12). Well, it doesn't "just work" for me. :(

clinfo returns two fatal errors:

fatal error: cannot open file '/usr/lib/clc/gfx1100-amdgcn-mesa-mesa3d.bc': No such file or directory

fatal error: cannot open file '/usr/lib/clc/gfx1030-amdgcn-mesa-mesa3d.bc': No such file or directory

I get similar errors when trying to run OpenCL-based programs.

I'm running a backported kernel, 6.6.13, and the latest Bookworm-supported mesa-opencl-icd, 22.3.6. From what I've found online, this should work, though Mesa 23.x is recommended. Is it safe/sane to install Mesa from Debian Trixie (testing)?

I've also seen references to AMD's official proprietary drivers. They do not officially support Debian, but can/should I run the Ubuntu installer anyway?

I'm hoping to get this up and running without any drastic measures like distro hopping. That said, if "upgrade to Testing or Unstable" is the simplest approach, I am willing to entertain the idea.

Thanks in advance for any help you can offer.

IT WORKS NOW! I will need time to run additional tests, but the gist of my solution was:

Backport llvm-18 from sid following the guide you linked at https://wiki.debian.org/SimpleBackportCreation
After compiling and installing all those deb files, I then installed the "jammy" version of amdgpu-install_6.0.60002-1.deb from https://www.amd.com/en/support/linux-drivers
Downloaded the latest kernel sources from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git, and simply copied all the files from its lib/firmware/amdgpu folder into my system's /lib/firmware/amdgpu. Got that idea from https://discussion.fedoraproject.org/t/amdgpu-doesnt-seem-to-function-with-navi-31-rx-7900-xtx/72647
sudo update-initramfs -u && sudo reboot

I'm not totally sure it step 3 was sane or necessary. Perhaps the missing piece before that was that I needed to manually update my initramfs? I've tried like a million things at this point and my system is dirty, so I will probably roll back to my snapshot from before all of this and attempt to re-do it with the minimal steps, when I have time.

Anyway, I was able to run a real-world OpenCL benchmark, and it's crazy-fast compared to my old GTX 1080. Actually a bigger difference than I expected. Like 6x.

THANKS FOR THE HELP!

Hell yeah.

Congratulations!
