      Remove ignore_value or void from unlink calls · e3a42028
      由 John Ferlan 提交于 
      There seems to be no need to add the ignore_value wrapper or
caste with (void) to the unlink() calls, so let's just remove
them. I assume at one point in time Coverity complained. So,
let's just be consistent - those that care to check the return
status can and those that don't can just have the naked unlink.

      conf: Introduce RDT monitor host capability · 6af84174
      由 Wang Huaqiang 提交于 
      This patch is introducing cache monitor(CMT) to cache and
memory bandwidth monitor(MBM) for monitoring CPU memory
bandwidth.

The host capability of the two monitors is also introduced
in this patch.

For CMT, the host capability is shown like:
  <host>
  ...
    <cache>
      <bank id='0' level='3' type='both' size='15' unit='MiB' cpus='0-5'>
        <control granularity='768' min='1536' unit='KiB' type='both' maxAllocs='4'/>
      </bank>
      <monitor level='3' 'reuseThreshold'='270336' maxMonitors='176'>
        <feature name='llc_occupancy'/>
      </monitor>
    </cache>
    ...
  </host>

For MBM, the capability is shown like this:
  <host>
    ...
    <memory_bandwidth>
      <node id='1' cpus='6-11'>
        <control granularity='10' min ='10' maxAllocs='4'/>
      </node>
      <monitor maxMonitors='176'>
        <feature name='mbm_total_bytes'/>
        <feature name='mbm_local_bytes'/>
      </monitor>
    </memory_bandwidth>
    ...
  </host>

      util: Introduce monitor capability interface · 12093f1f
      由 Wang Huaqiang 提交于 
      This patch introduces the resource monitor and creates the interface
for getting host capability of resource monitor from the system resource
control file system.

The resource monitor takes the role of RDT monitoring group and could be
used to monitor the resource consumption information, such as the last
level cache occupancy and the utilization of memory bandwidth.
