binding\n\nFirst clarifying that this kind of binding is not a replacement or an\nequivalent to the \u0027perf script\u0027 way of using python with 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 \u003cwilliams@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nCc: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nLKML-Reference: \u003cnew-submission\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "8115d60c323dd9931b95221c0a392aeddc1d6ef3", "tree": "13e75d71c5163c78efc9d8ab33988cc6c7be74a1", "parents": [ "8d50e5b4171a69cf48ca94a1e7c14033d0b4771d" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Sat Jan 29 14:01:45 2011 -0200" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Sat Jan 29 16:25:37 2011 -0200" }, "message": "perf tools: Kill event_t typedef, use \u0027union perf_event\u0027 instead\n\nAnd move the event_t methods to the perf_event__ too.\n\nNo code changes, just namespace consistency.\n\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nCc: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nLKML-Reference: \u003cnew-submission\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "8d50e5b4171a69cf48ca94a1e7c14033d0b4771d", "tree": "6ebf659f92f0770917c7f47c24449ebfe048ce61", "parents": [ "93fc64f14472ae24fd640bf3834a178f59142842" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Sat Jan 29 13:02:00 2011 -0200" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Sat Jan 29 16:25:20 2011 -0200" }, "message": "perf tools: Rename \u0027struct sample_data\u0027 to \u0027struct perf_sample\u0027\n\nMaking the namespace more uniform.\n\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nCc: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nLKML-Reference: \u003cnew-submission\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "93fc64f14472ae24fd640bf3834a178f59142842", "tree": "c527d0860e5151b1be00d873a0331de375d116f3", "parents": [ "7bb41152b9be7e31f10d8919bce5034135525d9d" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Sat Jan 29 12:08:00 2011 -0200" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Sat Jan 29 16:24:57 2011 -0200" }, "message": "perf top: Switch to non overwrite mode\n\nJust like \u0027perf record\u0027.

callchains three times:\n\n- 1st to resolve symbols\n- 2nd to filter out context boundaries\n- 3rd for the insertion into the tree\n\nThis also involves some pairs of memory allocation/deallocation\neverytime we insert a callchain, for the filtered out array of\naddresses and for the array of symbols that comes along.\n\nInstead, feed the callchains through a linked list with persistent\nallocations. It brings several pros like:\n\n- Merge the 1st and 2nd iterations in one. That was possible before\nbut in a way that would involve allocating an array slightly taller\nthan necessary because we don\u0027t know in advance the number of context\nboundaries to filter out.\n\n- Much lesser allocations/deallocations. The linked list keeps\npersistent empty entries for the next usages and is extendable at\nwill.\n\n- Makes it easier for multiple sources of callchains to feed a\nstacktrace together. This is deemed to pave the way for cfi based\ncallchains wherein traditional frame pointer based kernel\nstacktraces will precede cfi based user ones, producing an overall\ncallchain which size is hardly predictable. This requirement\nmakes the static array obsolete and makes a linked list based\niterator a much more flexible fit.\n\nBasic testing on a big perf file containing callchains (~ 176 MB)\nhas shown a

is implemented in all Sandy Bridge processors -- mobile, desktop and server.\nIt is expected to become increasingly important in subsequent generations.\n\nx86_energy_perf_policy is a user-space utility to set the\nhardware energy vs performance policy hint in the processor.\nMost systems would benefit from \"x86_energy_perf_policy normal\"\nat system startup, as the hardware default is maximum performance\nat the expense of energy efficiency.\n\nSee x86_energy_perf_policy.8 man page for more information.\n\nBackground:\n\nLinux-2.6.36 added \"epb\" to /proc/cpuinfo to indicate\nif an x86 processor supports MSR_IA32_ENERGY_PERF_BIAS,\nwithout actually modifying the MSR.\n\nIn March, 2010, Venkatesh Pallipadi proposed a small driver\nthat programmed MSR_IA32_ENERGY_PERF_BIAS,
