Since 2.10 QEMU supports a new display type egl-headless which uses the drm nodes for OpenGL rendering copying back the rendered bits back to QEMU into a dma-buf which can be accessed by standard "display" apps like VNC or SPICE. Although this display type can be used on its own, for any practical use case it makes sense to pair it with either VNC or SPICE display. The clear benefit of this display is that VNC gains OpenGL support, which it natively doesn't have, and SPICE gains remote OpenGL support (native OpenGL support only works locally through a UNIX socket, i.e. listen type=socket/none)Signed-off-by: Erik Skultety <[email protected]> --- docs/formatdomain.html.in | 33 +++++++++++- docs/schemas/domaincommon.rng | 3 ++ src/conf/domain_conf.c | 6 ++- src/conf/domain_conf.h | 1 + src/libxl/libxl_conf.c | 1 + src/qemu/qemu_command.c | 14 ++++- src/qemu/qemu_domain.c | 60 +++++++++++++++++++++- src/qemu/qemu_driver.c | 2 + src/qemu/qemu_hotplug.c | 1 + src/qemu/qemu_process.c | 4 ++ src/vmx/vmx.c | 1 + tests/domaincapsschemadata/full.xml | 1 + tests/qemuxml2argvdata/graphics-egl-headless.args | 26 ++++++++++ tests/qemuxml2argvdata/graphics-egl-headless.xml | 31 +++++++++++ .../qemuxml2argvdata/graphics-sdl-egl-headless.xml | 35 +++++++++++++ .../graphics-spice-egl-headless.args | 31 +++++++++++ .../graphics-spice-egl-headless.xml | 36 +++++++++++++ .../graphics-spice-invalid-egl-headless.xml | 37 +++++++++++++ .../graphics-vnc-egl-headless.args | 28 ++++++++++ .../qemuxml2argvdata/graphics-vnc-egl-headless.xml | 37 +++++++++++++ tests/qemuxml2argvtest.c | 17 ++++++ .../graphics-spice-egl-headless.xml | 44 ++++++++++++++++ .../graphics-vnc-egl-headless.xml | 42 +++++++++++++++ tests/qemuxml2xmltest.c | 2 + 24 files changed, 488 insertions(+), 5 deletions(-) create mode 100644 tests/qemuxml2argvdata/graphics-egl-headless.args create mode 100644 tests/qemuxml2argvdata/graphics-egl-headless.xml create mode 100644 tests/qemuxml2argvdata/graphics-sdl-egl-headless.xml create mode 100644 tests/qemuxml2argvdata/graphics-spice-egl-headless.args create mode 100644 tests/qemuxml2argvdata/graphics-spice-egl-headless.xml create mode 100644 tests/qemuxml2argvdata/graphics-spice-invalid-egl-headless.xml create mode 100644 tests/qemuxml2argvdata/graphics-vnc-egl-headless.args create mode 100644 tests/qemuxml2argvdata/graphics-vnc-egl-headless.xml create mode 100644 tests/qemuxml2xmloutdata/graphics-spice-egl-headless.xml create mode 100644 tests/qemuxml2xmloutdata/graphics-vnc-egl-headless.xml
