Subject: [PATCH v2 perf,bpf 0/3] reveal invisible bpf programs
Date: Tue, 4 Dec 2018 11:53:52 -0800 [thread overview]
Message-ID: <20181204195355.4079788-1-songliubraving@fb.com> (raw)
Changes v2 -> PATCH v1:
1. Only 3 of the 5 patches in v1, to focus on ABI first;
2. Generate PERF_RECORD_BPF_EVENT per bpf sub program instead of per prog;
3. Modify PERF_RECORD_BPF_EVENT with more details (addr, len, name),
so that it can be used for basic profiling without calling sys_bpf.
Changes RFC -> PATCH v1:
1. In perf-record, poll vip events in a separate thread;
2. Add tag to bpf prog name;
3. Small refactorings.
This is to follow up Alexei's early effort to show bpf programs
https://www.spinics.net/lists/netdev/msg524232.html
In this version, PERF_RECORD_BPF_EVENT is introduced to send real time BPF
load/unload events to user space.
Thanks,
Song
