[libvirt PATCH v4 0/6] Add support for 'blob' to virtio video device

Add support to libvirt for the 'blob' option for virtio video devices in qemu. Also do a little preparatory refactoring of the video device xml parsing code. I sent this series out a couple times but didn't get much review. Sending out again after fixing a few minor test- and doc-related things discussed in the last version and rebasing to current master branch. changes in v4: - rebased to latest master - updated tests changes in v3: - rebased to latest master Changes in v2: - Added some basic documentation - add a qemu capability - Make sure that the /dev/udmabuf device is accessible to qemu (cgroups, etc) Jonathon Jongsma (6): conf: Refactor video model parsing conf: switch to virXMLProp* functions conf: use enum variable for video type conf: add support for 'blob' in virtio video device qemu: Add capability for virtio-gpu.blob qemu: Implement 'blob' support for virtio gpu docs/formatdomain.rst | 7 + src/conf/domain_conf.c | 133 +++++++++--------- src/conf/domain_conf.h | 3 +- src/conf/domain_validate.c | 13 +- src/conf/schemas/domaincommon.rng | 5 + src/libxl/libxl_conf.c | 10 ++ src/libxl/libxl_domain.c | 11 ++ src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_cgroup.c | 22 ++- src/qemu/qemu_command.c | 3 + src/qemu/qemu_domain.h | 1 + src/qemu/qemu_monitor_json.c | 16 ++- src/qemu/qemu_namespace.c | 22 +++ src/qemu/qemu_process.c | 7 + src/qemu/qemu_validate.c | 9 ++ .../caps_6.1.0.x86_64.xml | 1 + .../caps_6.2.0.aarch64.xml | 1 + .../qemucapabilitiesdata/caps_6.2.0.ppc64.xml | 1 + .../caps_6.2.0.x86_64.xml | 1 + .../caps_7.0.0.aarch64.xml | 1 + .../qemucapabilitiesdata/caps_7.0.0.ppc64.xml | 1 + .../caps_7.0.0.x86_64.xml | 1 + .../caps_7.1.0.x86_64.xml | 1 + ...ideo-virtio-blob-absent.x86_64-latest.args | 39 +++++ .../video-virtio-blob-absent.xml | 36 +++++ .../video-virtio-blob-off.x86_64-latest.args | 39 +++++ .../video-virtio-blob-off.xml | 36 +++++ .../video-virtio-blob-on.x86_64-latest.args | 39 +++++ .../qemuxml2argvdata/video-virtio-blob-on.xml | 36 +++++ tests/qemuxml2argvtest.c | 3 + ...video-virtio-blob-absent.x86_64-latest.xml | 48 +++++++ .../video-virtio-blob-off.x86_64-latest.xml | 48 +++++++ .../video-virtio-blob-on.x86_64-latest.xml | 48 +++++++ tests/qemuxml2xmltest.c | 3 + 35 files changed, 567 insertions(+), 81 deletions(-) create mode 100644 tests/qemuxml2argvdata/video-virtio-blob-absent.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/video-virtio-blob-absent.xml create mode 100644 tests/qemuxml2argvdata/video-virtio-blob-off.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/video-virtio-blob-off.xml create mode 100644 tests/qemuxml2argvdata/video-virtio-blob-on.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/video-virtio-blob-on.xml create mode 100644 tests/qemuxml2xmloutdata/video-virtio-blob-absent.x86_64-latest.xml create mode 100644 tests/qemuxml2xmloutdata/video-virtio-blob-off.x86_64-latest.xml create mode 100644 tests/qemuxml2xmloutdata/video-virtio-blob-on.x86_64-latest.xml -- 2.37.1
