Intel E5-2600 series hardware performance counter support

Solution Unverified - Updated -

Environment

  • Red Hat Enterprise Linux (RHEL) 6

Issue

  • I have just a principle question about support of the E5-2600 Intel processor in the Red Hat Enterprise Linux (RHEL). Intel defines a large set of performance counter in the design of the chip, the question is: "Does the RHEL fully support the whole set of performance counter available within this version of processor ?"
  • Do you have an exhaustive list of available (and correct) counter supported?

Resolution

This is the uncore/PMU feature.

Upstream started working on this here: http://marc.info/?l=linux-kernel&m=129126703923098&w=2.

RHEL supports this in RHEL6.4GA for the Nehalem-EX chipsets. Implementation was tracked in (private) bz696579. The 6.4_Release_Notes contain more details.

Support for uncore/PMU with the E5-2600 Intel processor is available in RHEL6.5GA and later, as mentioned in the 6.5_Release_Notes.
