Overview

In order to share code with binutils, QEMU needs to relicense to GPLv2 or later since binutils is GPLv3. Since only a handful of files are licensed under GPLv2, it should be practical to relicense.

How to Help

To relicense a file, use the following git command to get a list of authors:

git log --format:"%an <%ae>" -- file.c

Check this wiki page to see if the author has already committed to relicensing. If so, add their Signed-off-by to the patch. For any author that hasn't already committed to relicensing, contact that individual and ask them if they are willing to relicense and collect their Signed-off-by.

Commitments to Relicense

If you or your company is willing to relicense your past contributions from GPLv2 to GPLv2+, please send an email to qemu-devel stating that explicitly and then link to that message on this wiki.

Files under LGPLv2/LGPLv2.1

These do not need relicensing even if the "or later" clause were missing (see section 3):

block/qed.c
block/qed-check.c
block/qed-cluster.c
block/qed-gencb.c
block/qed.h
block/qed-l2-cache.c

qbool.c
qdict.c
qemu-coroutine.c
qerror.c
qfloat.c
qint.c
qjson.c
qlist.c
qstring.c
test-coroutine.c

Files under GPLv2+

These would need relicensing in order to do a blanket relicensing of QEMU (it is debatable whether this requires authorization of the copyright holders). However, the license is GPLv3-compatible, so they can be left as is: overall, QEMU would still be distributed as GPLv3, but the code from this files could be reused in GPLv2 projects:

block/vdi.c
hw/alpha_typhoon.c
hw/ccid-card-passthru.c
hw/empty_slot.c
hw/ppc440_bamboo.c
hw/ppc440.c
hw/usb-ccid.c
blockdev.c
device_tree.c
dma-helpers.c
kvm-all.c
kvm-stub.c
linux-aio.c
qemu-error.c
qemu-ga.c
qemu-io.c
qemu-thread-posix.c
qemu-thread-win32.c

The situation of this file is unclear:

net/tap-win32.c

Files under "GPL"

These files can be probably interpreted as being "GPLv1+". Relicensing is thus not needed.

hw/a9mpcore.c
hw/an5206.c
hw/arm11mpcore.c
hw/arm_boot.c
hw/arm_gic.c
