| 1 | The QEMU distribution includes both the QEMU emulator and |
| 2 | various firmware files. These are separate programs that are |
| 3 | distributed together for our users' convenience, and they have |
| 4 | separate licenses. |
| 5 | |
| 6 | The following points clarify the license of the QEMU emulator: |
| 7 | |
| 8 | 1) The QEMU emulator as a whole is released under the GNU General |
| 9 | Public License, version 2. |
| 10 | |
| 11 | 2) Parts of the QEMU emulator have specific licenses which are compatible |
| 12 | with the GNU General Public License, version 2. Hence each source file |
| 13 | contains its own licensing information. Source files with no licensing |
| 14 | information are released under the GNU General Public License, version |
| 15 | 2 or (at your option) any later version. |
| 16 | |
| 17 | As of July 2013, contributions under version 2 of the GNU General Public |
| 18 | License (and no later version) are only accepted for the following files |
| 19 | or directories: bsd-user/, linux-user/, hw/vfio/, hw/xen/xen_pt*. |
| 20 | |
| 21 | 3) The Tiny Code Generator (TCG) is mostly under the BSD or MIT licenses; |
| 22 | but some parts may be GPLv2 or other licenses. Again, see the |
| 23 | specific licensing information in each source file. |
| 24 | |
| 25 | 4) QEMU is a trademark of Fabrice Bellard. |
