[libvirt] [PATCH v2 0/3] Add support for bochs video device
Patch series v2, mostly containing changes suggested by Peter Krempa: - renamed libvirt device name from 'bochs-display' to 'bochs' - split capabilities change from schema/conf change - refactored logic in qemuBuildDeviceVideoStr() in a separate patch - returned pcieFlags instead of pciFlags in qemuDomainDeviceCalculatePCIConnectFlags Jonathon Jongsma (3): qemu: Add bochs-display capability qemu: minor refactor of video device string handling conf: add 'bochs' video display type docs/formatdomain.html.in | 5 +-- docs/schemas/domaincommon.rng | 1 + src/conf/domain_conf.c | 2 ++ src/conf/domain_conf.h | 1 + src/qemu/qemu_capabilities.c | 4 +++ src/qemu/qemu_capabilities.h | 3 ++ src/qemu/qemu_command.c | 19 +++++++---- src/qemu/qemu_domain.c | 1 + src/qemu/qemu_domain_address.c | 3 ++ .../qemucapabilitiesdata/caps_3.0.0.ppc64.xml | 1 + .../caps_3.0.0.x86_64.xml | 1 + .../qemucapabilitiesdata/caps_3.1.0.ppc64.xml | 1 + .../caps_3.1.0.x86_64.xml | 1 + .../caps_4.0.0.aarch64.xml | 1 + .../qemucapabilitiesdata/caps_4.0.0.ppc64.xml | 1 + .../caps_4.0.0.riscv32.xml | 1 + .../caps_4.0.0.riscv64.xml | 1 + .../caps_4.0.0.x86_64.xml | 1 + .../caps_4.1.0.x86_64.xml | 1 + .../video-bochs-display-device.args | 32 +++++++++++++++++++ .../video-bochs-display-device.xml | 29 +++++++++++++++++ tests/qemuxml2argvtest.c | 3 ++ 22 files changed, 104 insertions(+), 9 deletions(-) create mode 100644 tests/qemuxml2argvdata/video-bochs-display-device.args create mode 100644 tests/qemuxml2argvdata/video-bochs-display-device.xml -- 2.20.1

In preparation for adding the bochs display device, refactor the logic so that each branch handles a single device type and checks its parameters within that branch. In this case VGA and VMVGA are still grouped into the same branch since they share device-specific parameter names.

Update schema and configuration to allow specifying new video type of 'bochs'. Add implementation and tests for qemu.
Usually we split the XML addition from the driver impl, that is: * conf: schema, documentation, XML parsing and formating and XML test case * qemu: qemu_command.c changes, xml2argvtest Given that the enum checks would require the conf: patch to touch qemu anyway and the changes are minimal, I will not ask you to split them, but at least s/conf/qemu/ in the commit summary.

5.6.0 now
depending on the hypervisor features available. The purpose of the type <code>none</code> is to instruct libvirt not to add a default video device in the guest (see the paragraph above). diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index 31db599ab9..763480440c 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -3584,6 +3584,7 @@ <value>virtio</value> <value>gop</value> <value>none</value> + <value>bochs</value> </choice> </attribute> <group> diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 3323c9a5b1..6e89569d3b 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -738,6 +738,7 @@ VIR_ENUM_IMPL(virDomainVideo, "virtio", "gop", "none", + "bochs", );

Even though it's only implemented for the QEMU driver, please give it a separate case. Future readers might be confused why are we assigning a different default for virt types that don't even support the device.

Manually listing the capabilities makes it easy to forget one and it will not catch the case when a newly introduced capability breaks the old code. Please use DO_TEST_CAPS_LATEST Jano
