qemu discuss - Feb 2007 - Re: cannot load kqemu modul on solaris 5.10 3/05

When the accelerator module was ported it was released under CDDL because at the
time kqemu was proprietary. The interfaces it supports (headers) are BSD
licensed.

Since Sun owns the code, it can be relicensed under GPL now that kqemu itself is
GPL. The work is not derived from any GPL code, and was 100% written by myself
and Juergen Zimmermann as Sun employees, so it is not encumbered in any way.

kqemu won''t ship as part of Solaris distribution so license is not an
issue, just as ext2fs etc will never ship as part of Solaris but they exist and
are in use.

It''s not something that Sun could ever release.
As far as I know GPL''d code can not be linked into the kernel.
The license is not compatible with the CDDL.

That said, since the interface is now documented,
someone could write an entirely new implementation
of the kqemu interface from scratch for solaris and
that would be usable. It must not have any code from
any GPL''d file.

Why does Sun own the code, rather than you?
Are you sure?
Or did you get money for it?
