[libvirt] [PATCH v2.1] qemu_capabilities: introduce QEMU_CAPS_SD_CARD to probe sd-card drivers

From: Chen Hanxiao <chenhanxiao(a)gmail.com&gt; This patch introduces QEMU_CAPS_SD_CARD for probing whether qemu support SD card by: {"execute": "device-list-properties", "arguments":{"typename":"sd-card"}} It will be helpful for apps which used cmd 'virsh domcaps` etc. Also helpful for: https://bugzilla.redhat.com/show_bug.cgi?id=1387218 Signed-off-by: Chen Hanxiao <chenhanxiao(a)gmail.com&gt; --- v2: rebased on upstream v2.1: add doc/news.xml description rebased on upstream docs/news.xml | 9 +++++++++ src/qemu/qemu_capabilities.c | 9 +++++++-- src/qemu/qemu_capabilities.h | 1 + 3 files changed, 17 insertions(+), 2 deletions(-) diff --git a/docs/news.xml b/docs/news.xml index 584c9af..b218463 100644 --- a/docs/news.xml +++ b/docs/news.xml @@ -26,6 +26,15 @@ don't start it with unsupported features. </description> </change> + <change> + <summary> + qemu_capabilities: introduce QEMU_CAPS_SD_CARD to probe sd-card drivers + </summary> + <description> + The new QEMU capability flag will allow libvirt to probe sd-card + drivers. + </description> + </change> </section> <section title="Bug fixes"> <change/> diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 5694d0b..1828b30 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -359,6 +359,7 @@ VIR_ENUM_IMPL(virQEMUCaps, QEMU_CAPS_LAST, "query-cpu-model-expansion", /* 245 */ "virtio-net.host_mtu", "spice-rendernode", + "sd-card", ); @@ -1626,6 +1627,7 @@ struct virQEMUCapsStringFlags virQEMUCapsObjectTypes[] = { { "ivshmem-plain", QEMU_CAPS_DEVICE_IVSHMEM_PLAIN }, { "ivshmem-doorbell", QEMU_CAPS_DEVICE_IVSHMEM_DOORBELL }, { "vhost-scsi", QEMU_CAPS_DEVICE_VHOST_SCSI }, + { "sd-card", QEMU_CAPS_SD_CARD }, }; static struct virQEMUCapsStringFlags virQEMUCapsObjectPropsVirtioBalloon[] = { @@ -5425,8 +5427,7 @@ virQEMUCapsFillDomainDeviceDiskCaps(virQEMUCapsPtr qemuCaps, VIR_DOMAIN_CAPS_ENUM_SET(disk->bus, VIR_DOMAIN_DISK_BUS_IDE, VIR_DOMAIN_DISK_BUS_SCSI, - VIR_DOMAIN_DISK_BUS_VIRTIO, - /* VIR_DOMAIN_DISK_BUS_SD */); + VIR_DOMAIN_DISK_BUS_VIRTIO); /* PowerPC pseries based VMs do not support floppy device */ if (!ARCH_IS_PPC64(qemuCaps->arch) || @@ -5435,6 +5436,10 @@ virQEMUCapsFillDomainDeviceDiskCaps(virQEMUCapsPtr qemuCaps, if (virQEMUCapsGet(qemuCaps, QEMU_CAPS_DEVICE_USB_STORAGE)) VIR_DOMAIN_CAPS_ENUM_SET(disk->bus, VIR_DOMAIN_DISK_BUS_USB); + + if (virQEMUCapsGet(qemuCaps, QEMU_CAPS_SD_CARD)) + VIR_DOMAIN_CAPS_ENUM_SET(disk->bus, VIR_DOMAIN_DISK_BUS_SD); + return 0; } diff --git a/src/qemu/qemu_capabilities.h b/src/qemu/qemu_capabilities.h index cc9f46e..decca12 100644 --- a/src/qemu/qemu_capabilities.h +++ b/src/qemu/qemu_capabilities.h @@ -394,6 +394,7 @@ typedef enum { QEMU_CAPS_QUERY_CPU_MODEL_EXPANSION, /* qmp query-cpu-model-expansion */ QEMU_CAPS_VIRTIO_NET_HOST_MTU, /* virtio-net-*.host_mtu */ QEMU_CAPS_SPICE_RENDERNODE, /* -spice rendernode */ + QEMU_CAPS_SD_CARD, /* -sd SD-card.img */ QEMU_CAPS_LAST /* this must always be the last item */ } virQEMUCapsFlags; -- 2.7.4
