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.

[    2.423859] amdgpu 0000:26:00.0: Direct firmware load for
amdgpu/fiji_pfp.bin failed with erro
r -2
[    2.423860] amdgpu 0000:26:00.0: gfx8: Failed to load firmware
"amdgpu/fiji_pfp.bin"

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

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

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
