Subject: [PATCH] KVM test: Add perfmon into the guest tests
Date: Tue, 25 May 2010 11:05:21 +0800	[thread overview]
Message-ID: <20100525030521.24717.39758.stgit@localhost.localdomain> (raw)

perfmon2 API provides access to the hardware performance counters of
modern processors.

Dependency,
To compile the source code of the test, the following packages should
be installed,
        glibc-static-2.11.1-6.x86_64
        glibc-headers-2.11.1-6.x86_64
        glibc-common-2.11.1-6.x86_64
        glibc-devel-2.11.1-6.x86_64
        glibc-2.11.1-6.x86_64

Note,
1. libpfm uses the Performance Monitor Unit (PMU) on the processors,
but this unit is not provided by kvm currently, i.e. the test should
fail in kvm guests.
2. According to the README file of perfmon-tests-0.3, 2.6.24 or higer
Linux kernel (with perfmon v2.8 or higher) is needed to run the tests.
