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>
