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.

Hello,

So I just bought a 7900 XTX and put it in my Libreboot 9020 MT motherboard (I have a custom build that I made for myself), it says during bootup of Debian:

"amdgpu 0000:03:00.0: firmware: failed to load amdgpu/gc_11_00_0_mes_2.bin (-2)"

I took out the GPU, booted into the OS without errors, and checked if the firmware-amd-graphics package was installed, which it was. I'm new to AMD, wondering if anyone else has had the same issue before.

I recently upgraded to a 7900 XTX on Debian stable, as well. I'm running the newest kernel from Debian's backports repo (6.6, I think), and I didn't have that same problem.

I did have other problems with OpenCL, though. I made a thread about this and solved it with some trouble. Check my post history if you're interested. I hope it helps. I can take a closer look at my now-working system for comparison if you have further issues.

Shouldn't that be "gc_11_0_0_mes_2.bin" — without the double 0? That you could download from git.kernel.org among other places.

That video card came out around the same time as the current version of Debian stable, so it's probably too new to be included in your version of firmware-amd-graphics. It would go in /usr/lib/firmware/amdgpu/ with a bunch of similar-looking files. The other thing you might need to go with that firmware is a newer linux kernel, which you could get from backports.

Yeah, Debian has older firmware found in the firmware-amd-graphics package which doesn't include the firmware. You'll need to download it from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ I believe anything from linux-firmware-20231030 and newer should work.

20231030 tag: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu?h=20231030 or newest(20240410) tag: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu?h=20240410

These files need to be placed in /lib/firmware/amdgpu/
