Phoronix: Linux 6.3 Will Better Handle Missing AMD Radeon Firmware / Unsupported Hardware

Another batch of AMDGPU/AMDKFD feature code was submitted this week to DRM-Next as additional AMD Radeon kernel graphics driver changes slated for Linux 6.3...

Is this firmware really needed? I just have in my amdgpu folder the firmware with the codename of my gpu and everything seems to be fine.

It would be nice if the kernel also printed the names of the missing firmware files it requires.
Quite a game currently when trying to find the smallest set of them that includes all the necessary ones for a specific GPU. Will only get harded with IP-based versioning. 😔

It will with this patch series.

depends on the circumstances.
If a GPU in your system has those IP blocks yes.

The driver has always printed the name of the firmware that was missing even prior to these changes.

Yeah it was just a lot harder to get to unless you had SSH setup since the screen froze.

But wasn't it like it only printed the first failed firmware and it was possible that other ones were missed until you provided that first failed?
At least I do recall having to do 2-3 cycles in the past.
Nowadays, it's of course a little bit easier because of the naming scheme.

They've moving from having a monolithic firmware for each GPU to having a file for each of the hardware blocks. I think those will be needed for the latest (7000 series) GPUs while earlier models still use the single-firmware-per-GPU files.

Thanks for the answer, that's a better approach.

That's a pretty good idea. I've just submitted a change for review to do just that.
