| From | Wang Nan <> | Subject | [RFC PATCH v3 35/37] perf tools: Add a bpf_wrapper global flag | Date | Sun, 17 May 2015 10:57:00 +0000 |
| |
The newly introduced flag is a indicator for 'perf bpf'. When commands like 'cmd_record' is started using 'perf bpf', they should consider the binding of bpf programs.
