int perf_evlist__mmap ( struct perf_evlist *  evlist,
unsigned int  pages,
bool  overwrite 
)

perf_evlist__mmap - Create per cpu maps to receive events

- list of events - map length in pages - overwrite older events?

If overwrite is false the user needs to signal event consuption using:

struct perf_mmap *m = &evlist->mmap[cpu]; unsigned int head = perf_mmap__read_head(m);

perf_mmap__write_tail(m, head)

Using perf_evlist__read_on_cpu does this automatically.
