Re: [libvirt] [PATCH v2 4/5] qemu: add virtio-gpu virgl support

Check if virtio-gpu provides virgl option, and add qemu command line formatter. It is enabled with the existing accel3d attribute: <model type='virtio' heads='1'> <acceleration accel3d='yes'/> </model> Signed-off-by: Marc-André Lureau <marcandre.lureau(a)gmail.com&gt; --- src/qemu/qemu_capabilities.c | 7 ++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 17 +++- tests/qemucapabilitiesdata/caps_1.2.2-1.replies | 22 +++-- tests/qemucapabilitiesdata/caps_1.3.1-1.replies | 22 +++-- tests/qemucapabilitiesdata/caps_1.4.2-1.replies | 22 +++-- tests/qemucapabilitiesdata/caps_1.5.3-1.replies | 22 +++-- tests/qemucapabilitiesdata/caps_1.6.0-1.replies | 22 +++-- tests/qemucapabilitiesdata/caps_1.6.50-1.replies | 22 +++-- tests/qemucapabilitiesdata/caps_2.1.1-1.replies | 22 +++-- tests/qemucapabilitiesdata/caps_2.4.0-1.replies | 95 ++++++++++++++++++-- tests/qemucapabilitiesdata/caps_2.5.0-1.caps | 1 + tests/qemucapabilitiesdata/caps_2.5.0-1.replies | 100 +++++++++++++++++++-- .../qemuxml2argv-video-virtio-gpu-virgl.args | 23 +++++ .../qemuxml2argv-video-virtio-gpu-virgl.xml | 33 +++++++ tests/qemuxml2argvtest.c | 4 + tests/qemuxml2xmltest.c | 1 + 17 files changed, 372 insertions(+), 64 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-video-virtio-gpu-virgl.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-video-virtio-gpu-virgl.xml
