This series adds support for the QEMU iothread poll-weight property, which controls the weight of the most recent event interval in the adaptive polling duration calculation. The valid range is [0, 63]; a value of 0 lets QEMU use its default weight. Changes in v2: - Move the formatdomain docs patch right after the XML parser/formatter patch - Fix the docs description: "If omitted, the value is not changed" rather than "If omitted or set to 0, the hypervisor selects a default" - Split the getter/stats path (patch 4) from the setter/cmdline path (patch 5), and drop the qemuBuildIOThreadCommandLine qemuCaps parameter since CAPS validation is handled by qemuValidateDomainDefIOThreads - Separate the test driver changes into its own patch (patch 6) with the corresponding iothreads.out updates split accordingly - Move the domstats documentation hunk into the stats patch (patch 4) - Add a qemuxmlconf parse-error test for out-of-range weight values - Fix Since version: 12.6.0 -> 12.7.0 (Peter Krempa) - Drop the docs: fix typos patch (already applied upstream) The series was validated with: meson test -C build virschematest meson test -C build qemucapabilitiestest meson test -C build qemuxmlconftest meson test -C build virshtest meson test -C build genericxml2xmltest QEMU commits: 9fea80ddf0 qapi/iothread: introduce poll-weight parameter for aio-poll 9563d0b5e2 aio-poll: refine iothread polling using weighted handler intervals ed21d9d65c aio-poll: avoid unnecessary polling time computation Jaehoon Kim (7): conf: add iothread poll-weight XML support docs: formatdomain: document iothread poll-weight qemu: capabilities: add capability for iothread poll-weight qemu: add poll-weight getter and stats support qemu: support iothread poll-weight test: add poll-weight support to the test driver virsh: add iothreadset --poll-weight support docs/formatdomain.rst | 8 ++- docs/manpages/virsh.rst | 18 ++++-- include/libvirt/libvirt-domain.h | 25 ++++++++ src/conf/domain_conf.c | 14 ++++- src/conf/domain_conf.h | 2 + src/conf/domain_validate.c | 7 +++ src/conf/schemas/domaincommon.rng | 5 ++ src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 6 ++ src/qemu/qemu_driver.c | 38 ++++++++++++ src/qemu/qemu_monitor.h | 2 + src/qemu/qemu_monitor_json.c | 18 ++++++ src/qemu/qemu_validate.c | 10 +++- src/test/test_driver.c | 12 ++++ tests/genericxml2xmlindata/iothreadids.xml | 2 +- .../caps_11.1.0_aarch64.xml | 1 + .../caps_11.1.0_x86_64.xml | 1 + ...s-poll-weight-outofrange.x86_64-latest.err | 1 + .../iothreads-ids-poll-weight-outofrange.xml | 58 +++++++++++++++++++ ...threads-ids-poll-weight.x86_64-latest.args | 40 +++++++++++++ ...othreads-ids-poll-weight.x86_64-latest.xml | 58 +++++++++++++++++++ .../iothreads-ids-poll-weight.xml | 58 +++++++++++++++++++ tests/qemuxmlconftest.c | 2 + tests/virshtestdata/iothreads.in | 2 + tests/virshtestdata/iothreads.out | 18 ++++++ tools/virsh-domain.c | 17 ++++++ 27 files changed, 415 insertions(+), 11 deletions(-) create mode 100644 tests/qemuxmlconfdata/iothreads-ids-poll-weight-outofrange.x86_64-latest.err create mode 100644 tests/qemuxmlconfdata/iothreads-ids-poll-weight-outofrange.xml create mode 100644 tests/qemuxmlconfdata/iothreads-ids-poll-weight.x86_64-latest.args create mode 100644 tests/qemuxmlconfdata/iothreads-ids-poll-weight.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/iothreads-ids-poll-weight.xml -- 2.54.0
