[PATCH v2 00/13] perf tools: BPF related update

From: Wang Nan
Date: Fri Nov 27 2015 - 03:52:01 EST


This patch set is based on perf/core.

Compare with v1:
- Patch 1/13 and 9/13: make code compat based on Arnaldo's suggestion;
- Patch 4/13: fix a bug which incorrectly use list_is_singular() test
whether a list entry is deleted from a list;
- Patch 13/13: change another test case.

This patch set improves perf's BPF support:

- Support filling BPF array with values

Users are allowed to pass something to BPF program through command
line without changing the program itself.

- Support filling BPF event array with events

BPF program can read PMU counters through BPF's perf_event_read()
helper.

- Support bpf_output_event() helper

BPF program can issue perf event to perf.data.

In most of the patches I list commands for testing them, both normal
case and error case.

He Kuang (1):
perf tools: Support perf event alias name

Wang Nan (12):
bpf tools: Collect map definition in bpf_object
bpf tools: Extract and collect map names from BPF object file
perf tools: Rename bpf config to program config
perf tools: Add API to config maps in bpf object
perf tools: Enable BPF object configure syntax
perf record: Apply config to BPF objects before recording
perf tools: Enable passing event to BPF object
perf tools: Support setting different slots in a BPF map separately
perf tools: Enable indices setting syntax for BPF maps
perf tools: Introduce bpf-output event
perf data: Add u32_hex data type
perf data: Support converting data from bpf_perf_event_output()
