Re: [PATCH] qemu: Add virtio related options to vsock

Add virtio related options iommu, ats and packed as driver element attributes to vsock devices. Ex: <vsock model='virtio'> <cid auto='no' address='3'/> <driver iommu='on'/> </vsock> Signed-off-by: Boris Fiuczynski <fiuczy(a)linux.ibm.com&gt; --- docs/formatdomain.rst | 2 + docs/schemas/domaincommon.rng | 5 +++ src/conf/domain_conf.c | 34 +++++++++++++-- src/conf/domain_conf.h | 1 + src/qemu/qemu_command.c | 3 ++ src/qemu/qemu_validate.c | 3 ++ .../vhost-vsock-ccw-iommu.s390x-latest.args | 42 +++++++++++++++++++ .../vhost-vsock-ccw-iommu.xml | 33 +++++++++++++++ tests/qemuxml2argvtest.c | 1 + .../vhost-vsock-ccw-iommu.s390x-latest.xml | 37 ++++++++++++++++ tests/qemuxml2xmltest.c | 2 + 11 files changed, 160 insertions(+), 3 deletions(-) create mode 100644 tests/qemuxml2argvdata/vhost-vsock-ccw-iommu.s390x-latest.args create mode 100644 tests/qemuxml2argvdata/vhost-vsock-ccw-iommu.xml create mode 100644 tests/qemuxml2xmloutdata/vhost-vsock-ccw-iommu.s390x-latest.xml diff --git a/docs/formatdomain.rst b/docs/formatdomain.rst index c738078b90..a09868bed5 100644 --- a/docs/formatdomain.rst +++ b/docs/formatdomain.rst @@ -7433,6 +7433,8 @@ devices <#elementsVirtioTransitional>`__ for more details.
