Okay, cool, this comes better than my patches and have some differences.
I am open with this as long as that it can meet cache allocation requires and
everyone will be happy.
I am ++ for this.
But I am not sure expose all of cache information in the capabilities XML.
</topology>+ <cache>+ <bank id='0' level='3' type='unified' size='8192' unit='KiB' cpus='0-7'/>
eg: if enabled CDP feature on the host, what the type of level=3 cache should be like?
+ <bank id='0' level='2' type='unified' size='256' unit='KiB' cpus='0-1'/>
for the bank id, it’s per cache level unique right (data/instruction shares same id)?
+ <bank id='0' level='1' type='instruction' size='32' unit='KiB' cpus='0-1'/>+ <bank id='0' level='1' type='data' size='32' unit='KiB' cpus='0-1'/>+ <bank id='1' level='2' type='unified' size='256' unit='KiB' cpus='2-3'/>+ <bank id='1' level='1' type='instruction' size='32' unit='KiB' cpus='2-3'/>+ <bank id='1' level='1' type='data' size='32' unit='KiB' cpus='2-3'/>+ <bank id='2' level='2' type='unified' size='256' unit='KiB' cpus='4-5'/>+ <bank id='2' level='1' type='instruction' size='32' unit='KiB' cpus='4-5'/>+ <bank id='2' level='1' type='data' size='32' unit='KiB' cpus='4-5'/>+ <bank id='3' level='2' type='unified' size='256' unit='KiB' cpus='6-7'/>+ <bank id='3' level='1' type='instruction' size='32' unit='KiB' cpus='6-7'/>+ <bank id='3' level='1' type='data' size='32' unit='KiB' cpus='6-7'/>+ </cache>
This’s really good that you have work this out by expose all these out to capabilities,
and it will be much easy to let resctrl keep focus on cache allocation.
So if util/virresctrl.c would like to access some cache abilities, it will first get virCapsPtr.host.caches,
right?
but I am not sure if that’s be okay to expose all cache information which we can not
do the allocation yet.
How can a user/admin to know from capabilities?
