perf.\n\nThe \u0027perf script\u0027 way is to process events and look at a given script\nfor some python function that matches the events to pass each event for\nprocessing.\n\nThis is a python module, i.e. everything is driven from the python\nscript, that merely uses \"import perf\" or \"from perf import\".\n\nperf script is focused on tracepoints, this binding is focused on profiling as\nan initial target. More work is needed to make available tracepoint specific\nvariables as event variables accessible via this binding.\n\nThere is one example of such usage model, in\ntools/perf/python/twatch.py, a tool to watch \"cycles\" events together\nwith task (fork, exit) and comm perf events.\n\nFor now, due to me not being able to grok how python distutils cope with\nbuilding C extensions outside the sources dir the install target just\nbuilds it, I\u0027m using it as:\n\n[root@emilia linux]# export PYTHONPATH\u003d~acme/git/build/perf/lib.linux-x86_64-2.6/\n[root@emilia linux]# tools/perf/python/twatch.py\ncpu: 4, pid: 30126, tid: 30126 { type: mmap, pid: 30126, tid: 30126, start: 0x4, length: 0x82e9ca03, offset: 0, filename: }\ncpu: 6, pid: 47, tid: 47 { type: mmap, pid: 47, tid: 47, start: 0x6, length: 0xbef87c36, offset: 0, filename: }\ncpu: 1, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0x1, length: 0x775d1904, offset: 0, filename: }\ncpu: 7, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0x7, length: 0xc750aeb6, offset: 0, filename: }\ncpu: 5, pid: 2255, tid: 2255 { type: mmap, pid: 2255, tid: 2255, start: 0x5, length: 0x76669635, offset: 0, filename: }\ncpu: 0, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0, length: 0x6422ef6b, offset: 0, filename: }\ncpu: 2, pid: 2255, tid: 2255 { type: mmap, pid: 2255, tid: 2255, start: 0x2, length: 0xe078757a, offset: 0, filename: }\ncpu: 1, pid: 5769, tid: 5769 { type: fork, pid: 30127, ppid: 5769, tid: 30127, ptid: 5769, time: 103893991270534}\ncpu: 6, pid: 30127, tid: 30127 { type: comm, pid: 30127, tid: 30127, comm: ls }\ncpu: 6, pid: 30127, tid: 30127 { type: exit, pid: 30127, ppid: 30127, tid: 30127, ptid: 30127, time: 103893993273024}\n\nThe first 8 mmap events in this 8 way machine are a mistery that is still being\ninvestigated.\n\nMore of the tools/perf/util/ APIs will be exposed via this python binding as\nthe need arises. For now the focus is on creating events and processing them,\nsymbol resolution is an obvious next step, with tracepoint variables as a close\nsecond step.\n\nCc: Clark Williams
