PMU in xen enviroment

[蒋雄伟(蒋. <xio...@al...>]

Hi，everyone


We would like to obtain the distribution of CPU-specific hardware events
such as clock cycles and cache and TLB misses and branch-miss and etc. in
Xen environment . It is said that Xenoprof can be used to do so. We use
Intel's Ivy Bridge Processor which is released in 2012, so I think it is
better to use oprofile 0.9.8 or above. But http://xenoprof.sourceforge.net/
only released oprofile-0.9.5-xen.patch which is released in 2009. Does it
mean no patch is needed since OProfile 0.9.6 ? is there a detailed document
describing how to use oprofile in xen environment ? is there any other tools
to do so ?


Thanks a lot.
