PEBS?

Hi!

Does the PEBS code really work from userspace? I am struggling with whether the DS address can really be programmed: http://stackoverflow.com/questions/32869524/x86-64-linear-address-for-pebs-from-linux-userspace?noredirect=1#comment53571195_32869524

The PEBS code isn't mine; please contact Barry Rountree (rountree4@llnl.gov). He has done some work with PEBS. In regard to your link, the MSR writes in our library are handled through /dev/cpu/*/msr via the msr kernel module.
