That's easy enough. We can automatically generate a tree _from_ Linus' 
tree, with a scripted transform so that it includes only the firmware 
files (much like the kernel-headers tree automatically follows each 
commit in Linus' tree, but includes only the exported headers).

And there are some hardware manufacturers who are willing to have their 
firmware included in such a firmware tarball, but who will _not_ give 
their permission to have it included in the Linux kernel because of the 
legal concerns you're so dismissive of. But that's OK -- we can pull 
from the automatically generated tree into a 'real' linux-firmware.git 
tree, which includes those extra firmware files.

But there's no need to do it _now_. It can wait until the basic stuff is 
in Linus' tree and it can automatically derive from that. There's no 
particular rush, is there?

That makes a certain amount of sense.


Please don't be gratuitously offensive, Ted. It's not polite, and it's 
not a particularly good debating technique either. I expect better from you.

The distros are certainly willing (and keen) to do it. The Fedora 
Engineering Steering Committee has already stated that it wants to do 
so, and the specfile changes to spit out a 'kernel-firmware' sub-package 
with the kernel build are ready to go right now.

Fedora already modifies tarballs, for example 'openssh-5.0p1-noacss'. I 
think it's quite likely they'd end up using a 'linux-2.6.27-nofirmware' 
tarball too, and build the firmware package from the separate tree.

Some other distributions have been doing that kind of thing _already_, 
even when it meant just ripping out certain drivers completely. That 
seems excessive to me; I prefer not to actually _break_ anything.

I disagree that the _default_ is such an issue -- largely because the 
normal case for modern drivers is not to include the firmware _anyway_, 
and the tools like 'mkinitrd' already cope with it just fine.

But I've changed the default to 'y' now, as I already said.
