[PATCH] qemu: Support vhost-vdpa-device.
by Yunfeng Qi 20 Mar '24

20 Mar '24

Since 8.0 version, qemu introduced a new device of 'vhost-vdpa-device-pci' that does not differentiate specific virtio devices, which called generic vDPA device. The generic vDPA solution avoids the need for maintaining a large amount of device emulation code, reducing maintenance costs.. the device configured as follows: <gvdpa> <source dev='/dev/vhost-vdpa-0'/> </gvdpa> Signed-off-by: Yunfeng Qi <yunfeng.qi(a)jaguarmicro.com> --- docs/formatdomain.rst | 17 +++ src/ch/ch_domain.c | 1 + src/conf/domain_conf.c | 106 ++++++++++++++++++ src/conf/domain_conf.h | 12 ++ src/conf/domain_postparse.c | 1 + src/conf/domain_validate.c | 11 ++ src/conf/schemas/domaincommon.rng | 23 ++++ src/conf/virconftypes.h | 2 + src/hyperv/hyperv_driver.c | 1 + src/libxl/libxl_driver.c | 6 + src/lxc/lxc_driver.c | 6 + src/qemu/qemu_alias.c | 21 ++++ src/qemu/qemu_cgroup.c | 6 + src/qemu/qemu_command.c | 55 +++++++++ src/qemu/qemu_domain.c | 3 + src/qemu/qemu_domain_address.c | 13 +++ src/qemu/qemu_driver.c | 3 + src/qemu/qemu_hotplug.c | 5 + src/qemu/qemu_validate.c | 12 ++ src/vz/vz_sdk.c | 3 + .../generic-vdpa.x86_64-latest.args | 34 ++++++ .../generic-vdpa.x86_64-latest.xml | 1 + tests/qemuxmlconfdata/generic-vdpa.xml | 43 +++++++ tests/qemuxmlconftest.c | 1 + 24 files changed, 386 insertions(+) create mode 100644 tests/qemuxmlconfdata/generic-vdpa.x86_64-latest.args create mode 120000 tests/qemuxmlconfdata/generic-vdpa.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/generic-vdpa.xml diff --git a/docs/formatdomain.rst b/docs/formatdomain.rst index 2adc2ff..182987b 100644 --- a/docs/formatdomain.rst +++ b/docs/formatdomain.rst @@ -8622,6 +8622,23 @@ The optional attribute ``backend`` is required if the ``type`` is ``qemu``, the ... +GVdpa +~~~~~~ + +A generic vdpa device. +The attribute ``dev`` is required and specifies the path of the generic vdpa device. + +:: + + ... + <devices> + <gvdpa> + <source dev='/dev/vhost-vdpa-0'/> + </gvdpa> + </devices> + ... + + Security label -------------- diff --git a/src/ch/ch_domain.c b/src/ch/ch_domain.c index 8e3e205..f9fbad6 100644 --- a/src/ch/ch_domain.c +++ b/src/ch/ch_domain.c @@ -180,6 +180,7 @@ chValidateDomainDeviceDef(const virDomainDeviceDef *dev, case VIR_DOMAIN_DEVICE_IOMMU: case VIR_DOMAIN_DEVICE_AUDIO: case VIR_DOMAIN_DEVICE_CRYPTO: + case VIR_DOMAIN_DEVICE_GVDPA: virReportError(VIR_ERR_CONFIG_UNSUPPORTED, _("Cloud-Hypervisor doesn't support '%1$s' device"), virDomainDeviceTypeToString(dev->type));

[PATCH 0/7] qemu XML testing improvements, part 3 - xmlout->xmlout testing and fixes
by Peter Krempa 19 Mar '24

19 Mar '24

This series depends on the 'part 2' with cover letter's subject: [PATCH 00/23] qemu XML testing improvements, part 2 - enforcement of xml->xml testing both this along with the rebased prerequisite series can be fetched from: git fetch https://gitlab.com/pipo.sk/libvirt.git test-improvements-3 The main goal of part 3 is to add testing based on parsing of the libvirt-formatted files from tests/qemuxml2xmloutdata and formatting them back, and checking that they are identical. By adding this testing multiple problems in code auto-adding information was discovered.

[RFC] virsysinfo: Try reading DMI table
by brett.holman＠canonical.com 19 Mar '24

19 Mar '24

This patch intends to add DMI support to libvirt for RISC-V and mips. This change is based on commit ec6ce6363, which added ARM support. This is not tested on the target arches, as I've been unable to find hardware to test this on. src/util/virsysinfo.c | 2 ++ 1 file changed, 2 insertions(+) Cheers, Brett Holman PS: This is my first post on this mailing list. I believe that I've followed the documented steps, but if I've missed anything please let me know.
