Plan to support Resctrl Control Monitors, which is a feature introduced
by kernel 'resctrl' sub-model. Submit some cleanup and refactoring patches
for upcoming memory bandwidth resource monitoring (MBM) monitors.
Related MBM RFC is
https://www.redhat.com/archives/libvir-list/2019-April/msg01409.html.
This RFC is not actively discussed since libvirt already implemented similar
resctrl cache monitoring (CMT), and lots details have been discussed
and implemented during the work of CMT.
The cleanups and refactoring includes:
1. Removing some reluctant lines and white spaces that is existing
in current code and not meet the libvirt coding style.
2. Replace 'virResctrlAllocIsEmpty' with @n==0 for indicating no
resctrl allocation in configuration file.
3. Private API changes, removed 'virResctrlMonitorGetCacheOccupancy'
and exported a new API named 'virResctrlMonitorGetStats' with similar
functionality, but with capability to be used for retrieving MBM
statistical information.
4. Refactoring 'virResctrlMonitorFreeStats' for more reusing in code.
5. Extend data structure 'virResctrlMonitorStats' with the capability
to carry multiple statistical information from monitor.
Wang Huaqiang (9):
conf: code cleanup, remove empty line and one space
conf: code cleanup for return error code directly
conf: check if vcpus matches with any 'existing' allocaiton
conf: Replace 'virResctrlAllocIsEmpty' with @n==0 for indicating no
resctrl allocation in configuration file
conf: refactor 'virDomainResctrlVcpuMatch'
util: Refactor 'virResctrlMonitorFreeStats'
util: Refactor 'virResctrlMonitorStats'
util: Extend virresctl API to retrieve multiple monitor statistics
util: Remove unused virResctrlMonitorGetCacheOccupancy
