perf stat: Pass through 'struct outstate'

2022-11-24T12:40:37Z

Now most of the print functions take a pointer to the struct outstate. We have one in the evlist__print_counters() and pass it through the child functions.

perf stat: Basic support for iostat in perf

2021-04-20T11:40:20Z

Add basic flow for a new iostat mode in perf. Mode is intended to provide four I/O performance metrics per each PCIe root port: Inbound Read, Inbound Write, Outbound Read, Outbound Write. The actual code to compute the metrics and attribute it to root port is in follow-on patches.
