[libvirt] [PATCH v2 00/12] Allow modification of IOThread polling values (redux)
Posted by John Ferlan 3 years, 7 months ago
v1: https://www.redhat.com/archives/libvir-list/2018-October/msg00456.html

Changes since v1 (from code review)

Patch 2: Move the job back into qemuDomainGetIOThreadsLive

Patch 3: Add check for ActiveJob before allowing, use true for
         *StatsWorker, and print 'iothread' in output not 'block'

Patch 5: Use virCheckPositiveArgGoto(nparams, error) instead of using
         virCheckNonNegativeArgGoto(nparams, error).  And then remove
         the if (nparams) before the virCheckNonNullArgGoto(params, error);

Patch 6: Add ability to determine which parameter was set via bool
         set_poll_{max_ns|grow|shrink} values.  Then use those in
         the macro that sets the value to determine whether or not
         the value will be set based on whether it was changed.

Patch 10: Use bool's to set_ when the value is found in the incoming
          params list.  Remove the check that says poll_max_ns needs
          to be set. Testing proves that if it's set to 0, then the
          grow and shrink values can be changed (although they do
          nothing)

Patch 12: (NEW) - News article

John Ferlan (12):
  qemu: Check for and return IOThread polling values if available
  qemu: Split qemuDomainGetIOThreadsLive
  qemu: Implement the ability to return IOThread stats
  virsh: Add ability to display IOThread stats
  lib: Introduce virDomainSetIOThreadParams
  qemu: Add monitor functions to set IOThread params
  qemu: Alter qemuDomainChgIOThread to take enum instead of bool
  qemu: Alter qemuDomainChgIOThread to take qemuMonitorIOThreadInfo
  qemu: Detect whether iothread polling is supported
  qemu: Introduce qemuDomainSetIOThreadParams
  tools: Add virsh iothreadset command
  docs: Add news article for IOThread polling
