[gem5-users] Re: syscall perf_event_open (#241) unimplemented
Hi It can be implemented in SE mode, but that would require us to implement/emulate perf_events in gem5 Is there a specific reason why you need to use perf_events in SE mode? Have you considered gathering statistics Through the gem5 ops?

[gem5-users] Re: syscall perf_event_open (#241) unimplemented
Hi Giacomo, Thanks for your reply. Is there any reason for implementing it in full system simulation only? Can we implement it in SE mode? Best regards.

Hi It has been fixed for full-system simulation (the patch you are referring to is providing visibility of the PMU to the linux kernel), But the syscall in SE mode is still un-implemented.
