Description Matt 2018-01-19 03:41:12 UTC 
on Fedora kernel 4.15rc7git4.1 and above with R9 NANO (Fiji) GPU dmesg shows a failure to load the firmware. cloned the latest firmware from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ still fails to load.

dropping back to 4.15rc7git0.1 and all loads correctly, no longer drops back to llvmpipe as a fallback.

Forgot to mention I have amdgpu.dc=1 kernel parameter set, however the same behaviour is exposed without the parameter
Comment 2 Alex Deucher 2018-01-19 07:16:46 UTC 
The firmware is not available for some reason.  Depending on how you've configured your kernel, make sure the firmware is either:
1. included in the initrd if you are using one
or
2. built into the kernel if the driver is built into the kernel
Comment 3 Matt 2018-01-19 11:20:57 UTC 
purged all my 4.15 kernels and reverted to the latest Fedora 4.14, then reinstalled 4.15 - that seems to have regenerated the initrd

all good now, resolving
