Not working on amdgpu with stock linux-firmware on Pitcairn

[DanPartelly]

I could not make amdvlk work on Pitcairn chipsets with the firmware from linux-firmware package, the images contained within are too old. It works amdgpu and firmware bundled into AMDs closed source stack. The solution is brittle, since the firmware will be overwritten on subsequent updates of the said package.

R7 370 and brothers, while old, are still perfectly adequate in a lot of circumstances, and it should be possible to run amdvlk on the open source stack out of the box on by modern Linux system.

What is the procedure/proper place to ask AMD to upstream latest firmware for those chipsets to linux-firmware , and what prevented AMD to update the ancient firmware for those chipsets to the latest versions shipping with closed source driver ? Are there technical issue with latest firmware and current incarnation of amdgpu/radeon ?

This problem also affects Verde chipsets

I've sent an email to the linux kernel maintainers for AMD graphics and CC'ed the amd-gfx mailing list.
