Patches submitted for purpose of refactoring existing 'resctrl' related
source code, including some code cleanups as well as some fixes. This is
also a preparation for memory bandwidth monitor codes.
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:
v2 changes:
1. Addressed comments of v1.
2. Introduce a new algorithm for verifying new monitor vcpus and existing
monitors and allocations.
3. Fixes for creating default-allocation-monitor in 'resctrl' file
system.(patch 0001).
v1 changes:
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 (11):
util,conf: Handle default monitor group of an allocation properly
conf: code cleanup, remove empty line and one space
conf: code cleanup for return error code directly
conf: some code cleanup
conf: refactor 'virDomainResctrlVcpuMatch' and some code cleanup
conf: Append 'resctrl' object according to number of monitor group
directly
util: Refactor and rename 'virResctrlMonitorFreeStats'
util: Refactor 'virResctrlMonitorStats'
util: Extend virresctl API to retrieve multiple monitor statistics
util: Remove unused virResctrlMonitorGetCacheOccupancy
conf: Refactor and rename the function to validate a new resctrl
monitor

Hi Michal, I think I make a mistake by not adding you into the mail receiver list since you are the reviewer of V1, and these patches have been submitted for more than two weeks. The v2 patches locates in this link: https://www.redhat.com/archives/libvir-list/2019-June/thread.html#00288 I wonder if you have time to have a review. Actually I aimed to submit the MBM patches, Which is ready based on these patches, and this series of patches for cleanups and fixes to existing codes to make the upcoming MBM patches to be more reasonable. If you think it is necessary to review the MBM patches as a whole , I can send them out shortly.
