PCIe PMU Root Complex Integrated End Point(RCiEP) device is supported
to sample bandwidth, latency, buffer occupation etc.
Each PMU RCiEP device monitors multiple root ports, and each RCiEP is
registered as a pmu in /sys/bus/event_source/devices, so users can
select target PMU, and use filter to do further sets.
Filtering options contains:
event - select the event.
subevent - select the subevent.
port - select target root ports. Information of root ports
are shown under sysfs.
bdf - select requester_id of target EP device.
trig_len - set trigger condition for starting event statistics.
trigger_mode - set trigger mode. 0 means starting to statistic when
bigger than trigger condition, and 1 means smaller.
thr_len - set threshold for statistics.
thr_mode - set threshold mode. 0 means count when bigger than
threshold, and 1 means smaller.

Hi Will,
Are you implying that you would rather that any review for these drivers
is done in public on the lists?
Cheers,
