[PATCH v2 0/7] qemu: add poll-weight support for iothreads
Posted by Jaehoon Kim 3 hours ago
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
