Subject[RFC PATCH v5 0/3] Make eBPF programs output data to perf
Date
Hi,

Previous patch v4 url:
http://thread.gmane.org/gmane.linux.kernel/1993353

This version we output bpf trace events in a hex array, the results
for three u64 integers in previous sample changed to this:

dd 1042 [000] 1296.122951: bpf:bpf_output_data: 7a ca aa c6 2d 01 00
00 95 87 ec ca 2d 01 00 00 1b bd 41 04 00 00 00 00

Users can interpret their own formats and get the result:

last=0x12dc6aaca7a, cur=0x12dcaec8795, del=0x441bd1b

v3-v4:
- Change u64 array in trace event to u8.
- Remove misleading 'perf event' in subject.

Thank you.

He Kuang (3):
tracing/events: Fix wrong sample output by storing array length
instead of size
tools lib traceevent: Add function to get dynamic arrays length
bpf: Introduce function for outputing trace event data
