I'm trying to run the latest PCM 2.5 on a machine with Intel(R) Xeon(R) CPU E5-2670 (Sandy Bridge), but PCM gives the below message and do not show any memory read/write access in the report.
Can not access SNB-EP (Jaketown) PCI configuration space. Access to uncore counters (memory and QPI bandwidth) is disabled.
You must be root to access these SNB-EP counters in PCM
Can you please guide me what am I missing here.
1. I'm running PCM as root and also looked at the DELL BIOS options for performance counters related to PCI but could not find any to enable or disable
