Re: [libvirt] [PATCH 00/11] qemu: Add support for ARM CPU features

Starting with QEMU 4.2.0, ARM guests support CPU features similarly to what's been the case on x86 since forever; notably, it's now possible to enable SVE (Scalable Vector Extension). Some of the patches in the series (notably 1/11) are snipped; the unabridged version can be obtained with $ git fetch https://gitlab.com/abologna/libvirt.git sve Andrea Bolognani (11): tests: Update capabilities for QEMU 4.2.0 on aarch64 qemu: Rename virQEMUCapsObjectPropsMaxX86CPU qemu: Introduce QEMU_CAPS_ARM_MAX_CPU qemu: Query max-arm-cpu properties qemu: Update query-cpu-model-expansion check qemu: Perform full expansion on ARM cpu_map: Introduce ARM CPU features cpu: Validate ARM CPU features qemu: Validate ARM CPU features tests: Introduce tests for ARM CPU features news: Update for ARM CPU features docs/news.xml | 9 + src/cpu/cpu_arm.c | 157 + src/cpu_map/arm_features.xml | 22 + src/cpu_map/index.xml | 4 + src/qemu/qemu_capabilities.c | 20 +- src/qemu/qemu_capabilities.h | 3 + src/qemu/qemu_command.c | 3 +- src/qemu/qemu_domain.c | 37 + .../qemu_4.2.0-virt.aarch64.xml | 2 +- tests/domaincapsdata/qemu_4.2.0.aarch64.xml | 2 +- .../caps_2.12.0.aarch64.replies | 159 +- .../caps_2.12.0.aarch64.xml | 1 + .../caps_4.0.0.aarch64.replies | 159 +- .../caps_4.0.0.aarch64.xml | 1 + .../caps_4.2.0.aarch64.replies | 3755 ++++++++++------- .../caps_4.2.0.aarch64.xml | 52 +- .../aarch64-features-sve-disabled.xml | 18 + .../aarch64-features-sve.aarch64-latest.args | 32 + .../qemuxml2argvdata/aarch64-features-sve.xml | 20 + .../aarch64-features-wrong.xml | 17 + tests/qemuxml2argvtest.c | 9 + .../aarch64-features-sve.aarch64-latest.xml | 31 + tests/qemuxml2xmltest.c | 3 + 23 files changed, 3029 insertions(+), 1487 deletions(-) create mode 100644 src/cpu_map/arm_features.xml create mode 100644 tests/qemuxml2argvdata/aarch64-features-sve-disabled.xml create mode 100644 tests/qemuxml2argvdata/aarch64-features-sve.aarch64-latest.args create mode 100644 tests/qemuxml2argvdata/aarch64-features-sve.xml create mode 100644 tests/qemuxml2argvdata/aarch64-features-wrong.xml create mode 100644 tests/qemuxml2xmloutdata/aarch64-features-sve.aarch64-latest.xml
