-g -a ./hackbench 10\n perf report -g fractal,10.0\n\nAnd you got:\n\n2.33% hackbench [kernel] [k] _spin_lock_irqsave\n |\n |--78.57%-- remove_wait_queue\n | poll_freewait\n | do_sys_poll\n |

a 7.14% branch whereas we passed a 10%\nfilter.\n\nThe problem is that we round down the minimum threshold. This\nhappens mostly when we have very low number of events. If the\ntotal amount of your branch is 4 and you have a subranch of 3\nevents, filtering to 90% will be computed like follows:\n\n limit \u003d 4 * 0.9;\n\nThe result is about 3.6, but the cast to integer will round\ndown to 3. It means that our filter is actually of 75%\n\nWe must then explicitly round up the minimum threshold.\n\nReported-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: acme@redhat.com\nCc: peterz@infradead.org\nCc: efault@gmx.de\nLKML-Reference: \u003c20090809024235.GA10146@nowhere\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "183f3b0887083d36c8a25cd5e3518906415d1889", "tree": "ede429e89d4e0553246454a5ee6b36c276872003", "parents": [ "c24b513337f06712b8c81eb4f1413d44591dfee7" ], "author": { "name": "Mike Galbraith", "email": "efault@gmx.de", "time": "Sat Aug 08 14:14:15 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Aug 09 12:54:47 2009 +0200" }, "message": "perf_counter tools: Fix libbfd detection for systems with libz dependency\n\nDue to a libz dependency in some distro\u0027s binutils package,\nC++ demangle support isn\u0027t compiled in despite the necessary\nlibraries being available.\n\nFix this by adding a -lz link test to the dependency detection\nrules.\n\nSigned-off-by: Mike Galbraith \u003cefault@gmx.de\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c1249733655.6929.5.camel@marge.simson.net\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "c24b513337f06712b8c81eb4f1413d44591dfee7", "tree": "803dc18c10e93c02cbd0f6b26a072fdc2194935d", "parents": [ "3a80b4a3539696f4b0574876326860323035a302" ], "author": { "name": "Carlos R.
