.SH DESCRIPTION

This family of probe points is used to probe "perf events"
on suitably configured kernels (2.6.33+).  It contains a
number of aliases for the ABI-specified event type/config
tuples.

.TP
.B perf.hw.*
A variety of hardware events, as generalized by the kernel.  These
generally require running on bare hardware with selected processors.
.SAMPLE
probe perf.hw.cpu_cycles
probe perf.hw.instructions
probe perf.hw.cache_references
probe perf.hw.cache_misses
probe perf.hw.branch_instructions
probe perf.hw.branch_misses
probe perf.hw.bus_cycles
.ESAMPLE

.TP
.B perf.sw.*
Special "software" events provided by the kernel.  These sometimes work
in virtualized environments and with more processor architectures.
.SAMPLE
probe perf.sw.cpu_clock
probe perf.sw.task_clock
probe perf.sw.page_faults
probe perf.sw.context_switches
probe perf.sw.cpu_migrations
probe perf.sw.page_faults_min
probe perf.sw.page_faults_maj
probe perf.sw.alignment_faults
probe perf.sw.emulation_faults
