[PATCH 0/6] qemu: add poll-weight support for iothreads
Posted by Jaehoon Kim 2 days, 12 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.

The series is split by layer:
  1) conf/schema support
  2) qemu capability detection
  3) qemu backend support + public API constants + xmlconf tests
  4) virsh support + test driver + virshtest
  5) docs: fix pre-existing typos in iothread poll element description
  6) docs: formatdomain documentation for poll-weight

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 (6):
  conf: add iothread poll-weight XML support
  qemu: capabilities: add capability for iothread poll-weight
  qemu: support iothread poll-weight
  virsh: add support for iothread poll-weight
  docs: fix typos in iothread poll element description
  docs: formatdomain: document iothread poll-weight
