Thread-topic: [Xen-devel] [PATCH] Xenperf Bug Fix
User-agent: Microsoft-Entourage/11.3.6.070618
If the VMEXIT reasons aren’t densely encoded (which they actually are, except for NPT), then rather than making the array an order of magnitude bigger it’s probably better either to define your own dense encoding (e.g., remap NPT==1024 to a lower number) or give NPT exits their own singleton counter which you increment in the existing ‘case VMEXIT_NPF’ in svm_vmexit_handler()).

This patch fixes/enables the following:
 
* Fix typo bug in xenperf tool.
* Increase the size of percpu data area from 4K to 8K to accommodate larger PERFCOUNTER_ARRAY.
* Increase the size of svmexits PERFCOUNTER_ARRAY to include nested paging perf counter.
