In the old days, firmware used to be for things which are covered
For radeon, R300 and later require it, but I'm unclear if you need
it to get a working KMS framebuffer. On older R600 chips, the
firmware was only needed to get Xorg running. On my most recent AMD
box, I'm not sure - my notes are ambiguous (or perhaps I'm grepping
for the wrong phrase), and I now always build the required firmware.
The firmware in the kernel source is only old things, nothing more
will be added there (I believe people complained that it wasn't
redistributable under the GPL v2). I suppose it is possible to copy
the files from kernel.org, but ISTR I had problems when I tried
doing that in firefox. For many people, copying a recent tarball
from a distro is probably the way to go, and then they can
periodically clone linux-firmware once they have built git.
At least one of my nics wants the firmware (I've seen error
messages when booting without it), but it seemed to work fine
without it! I suspect it maybe had an old version.
