Your "equery f" is wrong: # equery files sys-kernel/linux-firmware | grep -i kabini_pfp /lib/firmware/amdgpu/kabini_pfp.bin /lib/firmware/radeon/KABINI_pfp.bin /lib/firmware/radeon/kabini_pfp.bin # find /lib/firmware/ -iname '*kabini_pfp*' /lib/firmware/radeon/kabini_pfp.bin /lib/firmware/radeon/KABINI_pfp.bin /lib/firmware/amdgpu/kabini_pfp.bin # sha1sum /lib/firmware/radeon/kabini_pfp.bin 1bb75ecf7d1b6ee198bb6d8eb454d6b9e4ed7f8d /lib/firmware/radeon/kabini_pfp.bin # sha1sum /lib/firmware/radeon/KABINI_pfp.bin e1ea258af22770c90b858568c1eaf7031540ca64 /lib/firmware/radeon/KABINI_pfp.bin # sha1sum /lib/firmware/amdgpu/kabini_pfp.bin ee710c8e17cbc3ac4be02292d84afe93afae249e /lib/firmware/amdgpu/kabini_pfp.bin Also *we* do not move files. We just merge untouched upstream file layout. Also keep in mind that > Direct firmware load for amdgpu/kabini_pfp.bin failed with error -2 says nothing about the reason. For example for Intel wifi you often see > Direct firmware load for iwlwifi-7265D-26.ucode failed with error -2 > Direct firmware load for iwlwifi-7265D-25.ucode failed with error -2 > Direct firmware load for iwlwifi-7265D-24.ucode failed with error -2 > Direct firmware load for iwlwifi-7265D-23.ucode failed with error -2 > loaded firmware version 22.391740.0 op_mode iwlmvm I.e. driver ties to load a firmware file and somehow detects that this firmware isn't suitable for that device and tries another file. But error msg is the same: "-2". And if I am not wrong this file was never changed: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/log/amdgpu/kabini_pfp.bin So it looks like you have a different problem.
I'm using saveconfig for linux-firmware to get radeon/kabini* (that are needed acording to https://wiki.gentoo.org/wiki/AMDGPU) and firmware is builded into kernel, this machine was working with that for about 2 years. I just changed every radeon/kabini* to amdgpu/kabini* in saveconfig and kernel config, and looks like everythin is working now. Looks like there was some changes in kernel (and big yellow important box over firmware table at gentoo wiki) about which I didn't know.
Thank you for the feedback. Closing as invalid because no bug in ebuild/package.
