[PATCH 0/8] Testcase improvements and Power8E/NVL removal
by Aditya Gupta 01 Jul '26

01 Jul '26

Overview ======== This patch series merges two patch series sent earlier: "Testcase improvements for PowerNV" "Remove deprecated Power8E and 8NVL CPUs" since the Power8E removal series depended on the former due to pnv-spi test Broadly contains 3 changes: 1. Testcase improvements: Add a testcase to detect regression in remote interrupts when XIVE changes, since such regression had occurred during Power11 XIVE changes: https://lore.kernel.org/qemu-devel/baf6c854-832b-4a2e-922f-d34e6dadf821@red… Also add Power11 chip and testcase in qtests, and fadump functional test 2. Power8E/Power8NVL removal Power8E and Power8NVL were deprecated since QEMU 10.1, with commit 264a604e7163 ("target/ppc: Deprecate Power8E and Power8NVL") Hence, remove usage (chip and core types) of Power8E and 8NVL from PowerNV, PSeries as well as testcases. 3.

[PATCH v8 0/2] qemu: Support HW-accelerated vSMMUs

This Libvirt series leverages the auto support: users can omit SMMUv3 properties ATS, RIL, OAS, and SSIDSIZE on the domain XML, and they will also be omitted on the QEMU command line as a result. With these new QEMU series applied, the feature property values will default to 'auto' to be resolved based on what the host SMMU supports.

Omitting these properties in the XML omits them on the QEMU command line as well, which results in default auto values being chosen for ATS, RIL, SSIDSIZE, and OAS - Add validation check that only allows enabling accel SMMUv3 features when accel is enabled - Add tests for accel=on but omitting accel SMMUv3 feature properties Changes from v6: - Remove smmuv3 'pasid' attribute - Add smmuv3 'ssidsize' attribute - Add support for 'vpasidCapOffset' element - Modify logic for building accel smmuv3 qemu command line to omit ATS, RIL, accel flags when not needed (enabled/disabled by default in QEMU SMMUv3) Nathan Chen (2): qemu: Add support for HW-accelerated nested SMMUv3 tests: qemuxmlconfdata: provide HW-accel smmuv3 sample XML and CLI args docs/formatdomain.rst | 29 +++++++ src/conf/domain_conf.c | 80 +++++++++++++++++++ src/conf/domain_conf.h | 5 ++ src/conf/domain_validate.c | 27 ++++++- src/conf/schemas/domaincommon.rng | 25 ++++++ src/qemu/qemu_command.c | 5 ++ ...uv3-pci-bus-accel-auto.aarch64-latest.args | 38 +++++++++ ...muv3-pci-bus-accel-auto.aarch64-latest.xml | 63 +++++++++++++++ .../iommu-smmuv3-pci-bus-accel-auto.xml | 53 ++++++++++++ ...u-smmuv3-pci-bus-accel.aarch64-latest.args | 38 +++++++++ ...mu-smmuv3-pci-bus-accel.aarch64-latest.xml | 63 +++++++++++++++ .../iommu-smmuv3-pci-bus-accel.xml | 53 ++++++++++++ tests/qemuxmlconftest.c | 2 + 13 files changed, 480 insertions(+), 1 deletion(-) create mode 100644 tests/qemuxmlconfdata/iommu-smmuv3-pci-bus-accel-auto.aarch64-latest.args create mode 100644 tests/qemuxmlconfdata/iommu-smmuv3-pci-bus-accel-auto.aarch64-latest.xml create mode 100644 tests/qemuxmlconfdata/iommu-smmuv3-pci-bus-accel-auto.xml create mode 100644 tests/qemuxmlconfdata/iommu-smmuv3-pci-bus-accel.aarch64-latest.args create mode 100644 tests/qemuxmlconfdata/iommu-smmuv3-pci-bus-accel.aarch64-latest.xml create mode 100644 tests/qemuxmlconfdata/iommu-smmuv3-pci-bus-accel.xml -- 2.43.0

[PATCH 0/2] Properly handle tri-state for KVM options
by Chris Riches 30 Jun '26

30 Jun '26

Two of the qemu kvm_features (kvm-poll-control and kvm-pv-ipi) were only emitted when on or when off respectively, rather than handling the full tri-state for each (on, off, absent). This meant that config like <poll-control state='off'/> was a no-op, equivalent to not specifying poll-control at all, which fails to prevent QEMU from enabling it based on its own internal defaults. In particular, this meant that having both <cpu mode='host-passthrough'> and <poll-control state='off'/> would cause the latter to be ignored, since libvirt would emit no explicit kvm-poll-control arg, and QEMU defaults to enabling most KVM features when CPU passthrough is enabled. Fix these two cases such that explicit on/off are both respected. The `hidden` and `hint-dedicated` options are left as-is, since these really do only make sense in the `on` direction; QEMU will never automatically enable them.
