[Qemu-devel] ui/egl-helpers.c license and reuse

[Frediano Ziglio]

Hi,
  I work in the SPICE team (www.spice-space.org). I'd like to reuse some code from
this file for some test for our project. The license of the 2 projects are a bit
different (GPL2 against LGPL2) so in theory I couldn't do it.
The code is mainly doing EGL initialization.
Could I obtain a dispensation to reuse to code as LGPL2 ?
Alternatively where can I get similar code with compatible LGPL2 license ?

Regards,
  Frediano

"IANAL,"

Looks like the file was authored by four people with no explicit
license, so it defaulted to GPL2.

Cole Robinson, Gerd Hoffman, Gonglei, and Peter Maydell.

Maybe you can get explicit permission from these four.

Markus Armbruster also has a one-line deletion (although how can a line
no longer present in the file be holding up a copyright question?). It
depends on whether you use 'git blame' to track all contributors to the
current state of the file, or 'git log' to track all authors to any
changes to the file.  'git blame' may also come in handy if you only
need to copy a subset of the file.

The only change I made to it was an automated scripted one to
add the #include "qemu/osdep.h", so if that's not in the code
you want then you probably don't need to involve me/Linaro.

This specific case looks as non-copyrightable to me as they get.

I just fixed a memory leak reported by Coverity.

It's okay to me :)

I'm fine with relicensing the file.

I'd suggest you send a patch explicitly licensing the file to LGPLv2,
Cc'ing anyone who touched the file.  I'll go collect the ACKS and merge
the patch once we got them all.

cheers,
  Gerd
