I wanted to understand how xenoprof handles (if at all) saving of PMC/PMDs (data related to PMU) during a context switch.
I am looking at xenoprof.c and other files in oprofile code in xen-unstable/xen/...
I would like to know how it interacts with hypervisor..
Please let me know which files I should look at to understand hypervisor interactions.
