Wei Huang fc116efad0 kvm_stat: Add RESET support for perf event ioctl ... While running kvm_stat using tracepoint on ARM64 hardware (e.g. "kvm_stat -1 -t"), the initial values of some kvm_userspace_exit counters were found to be very suspecious. For instance the tracing tool showed that S390_TSCH was called many times on ARM64 machine, which apparently was wrong. This patch adds RESET ioctl support for perf monitoring. Before calling ioctl to enable a perf event, this patch resets the counter first. With this patch, the init counter values become correct on ARM64 hardware. Example: ==== before patch ==== kvm_userspace_exit(S390_SIEIC) 1426 0 kvm_userspace_exit(S390_TSCH) 339 0 ==== after patch ==== kvm_userspace_exit(S390_SIEIC) 0 0 kvm_userspace_exit(S390_TSCH) 0 0 Signed-off-by: Wei Huang <wei@redhat.com>		2015-01-26 12:27:05 +01:00
