From: Andi Kleen <ak@linux.intel.com>
Add a PERF_CPUID variable to override the CPUID of the current CPU. This is useful for testing, so that all event lists can be tested on a single system.
v2: Fix double free in earlier version. Signed-off-by: Andi Kleen <ak@linux.intel.com> --- tools/perf/util/pmu.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-)
