git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip\n\nPull perf events changes for v3.4 from Ingo Molnar:\n\n - New \"hardware based branch profiling\" feature both on the kernel and\n the tooling side, on CPUs that support it. (modern x86 Intel CPUs\n with the \u0027LBR\u0027 hardware feature currently.)\n\n This new feature is basically a sophisticated \u0027magnifying glass\u0027 for\n branch execution - something that is pretty difficult to extract from\n regular, function histogram centric profiles.\n\n The simplest mode is activated via \u0027perf record -b\u0027, and the result\n looks like this in perf report:\n\n\t$ perf record -b any_call,u -e cycles:u branchy\n\n\t$ perf report -b --sort\u003dsymbol\n\t 52.34% [.] main [.] f1\n\t 24.04% [.] f1 [.] f3\n\t 23.60% [.] f1 [.] f2\n\t 0.01% [k] _IO_new_file_xsputn [k] _IO_file_overflow\n\t 0.01% [k] _IO_vfprintf_internal [k] _IO_new_file_xsputn\n\t 0.01% [k] _IO_vfprintf_internal [k] strchrnul\n\t 0.01% [k] __printf [k] _IO_vfprintf_internal\n\t 0.01% [k] main [k] __printf\n\n This output shows from/to branch columns and shows the highest\n percentage (from,to) jump combinations - i.e. the most likely taken\n branches in the system. \"branches\" can also include function calls\n and any other synchronous and asynchronous transitions of the\n instruction pointer that are not \u0027next instruction\u0027 - such as system\n calls, traps, interrupts, etc.\n\n This feature comes with (hopefully intuitive) flat ascii and TUI\n support in perf report.\n\n - Various \u0027perf annotate\u0027 visual improvements for us assembly junkies.\n It will now recognize function calls in the TUI and by hitting enter\n you can follow the call (recursively) and back, amongst other\n improvements.\n\n - Multiple threads/processes recording support in perf record, perf\n stat, perf top - which is activated via a comma-list of PIDs:\n\n\tperf top -p 21483,21485\n\tperf stat -p 21483,21485 -ddd\n\tperf record -p 21483,21485\n\n - Support for per UID views, via the --uid paramter to perf top, perf\n report, etc. For example \u0027perf top --uid mingo\u0027 will only show the\n tasks that I am running, excluding other users, root, etc.\n\n - Jump label restructurings and improvements - this includes the\n factoring out of the (hopefully much clearer) include/linux/static_key.h\n generic facility:\n\n\tstruct static_key key \u003d STATIC_KEY_INIT_FALSE;\n\n\t...\n\n\tif (static_key_false(\u0026key))\n\t do unlikely code\n\telse\n\t do likely code\n\n\t...\n\tstatic_key_slow_inc();\n\t...\n\tstatic_key_slow_inc();\n\t...\n\n The static_key_false() branch will be generated into the code with as\n little impact to the likely code path as possible. the\n static_key_slow_*() APIs flip the branch via live kernel code patching.\n\n This facility can now be used more widely within the kernel to\n micro-optimize hot branches whose likelihood matches the static-key\n usage and fast/slow cost patterns.\n\n - SW function tracer improvements: perf support and filtering support.\n\n - Various hardenings of the perf.data ABI, to make older perf.data\u0027s\n smoother on newer tool versions, to make new features integrate more\n smoothly, to support cross-endian recording/analyzing workflows\n better, etc.\n\n - Restructuring of the kprobes code, the splitting out of \u0027optprobes\u0027,\n and a corner case bugfix.\n\n - Allow the tracing of kernel console output (printk).\n\n - Improvements/fixes to user-space RDPMC support, allowing user-space\n self-profiling code to extract PMU counts without performing any\n system calls, while playing nice with the kernel side.\n\n - \u0027perf bench\u0027 improvements\n\n - ... and lots of internal restructurings, cleanups and fixes that made\n these features possible.

So what\nwent wrong?\n\nThe problem is we assume snprintf returns the number of characters\nwritten:\n\n ret +\u003d repsep_snprintf(bf + ret, size - ret, \"[%c] \", self-\u003elevel);\n...\n ret +\u003d repsep_snprintf(bf + ret, size - ret, \"%s\", self-\u003ems.sym-\u003ename);\n\nUnfortunately this is not how snprintf works. snprintf returns the\nnumber of characters that would have been written if there was enough\nspace. In the above case, if the first snprintf returns a value larger\nthan size, we pass a negative size into the second snprintf and happily\nscribble over the stack. If you have 3000 character c++ methods thats a\nlot of stack to trample.\n\nThis patch fixes repsep_snprintf by clamping the value at size - 1 which\nis the maximum snprintf can write before adding the NULL terminator.\n\nI get the sinking feeling that there are a lot of other uses of snprintf\nthat have this same bug, we should audit them all.\n\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Eric B Munson \u003cemunson@mgebm.net\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Yanmin Zhang \u003cyanmin_zhang@linux.intel.com\u003e\nCc: stable@kernel.org\nLink: http://lkml.kernel.org/r/20120307114249.44275ca3@kryten\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "e485ceac9ebd43901ef0ce13622385d509e072e7", "tree": "74ba59bdaea967ab3dcc53fabd5dc163b2f2411c", "parents": [ "04bf30115f4ba2beda1efb6cfbae49cdc757f3a9" ], "author": { "name": "K.

The percentages reported in the first\ncolumn refer to the total number of branches captured and\nnot the usual number of samples.\n\nHere is a quick example.\nHere branchy is simple test program which looks as follows:\n\nvoid f2(void)\n{}\nvoid f3(void)\n{}\nvoid f1(unsigned long n)\n{\n if (n \u0026 1UL)\n f2();\n else\n f3();\n}\nint main(void)\n{\n unsigned long i;\n\n for (i\u003d0; i \u003c N; i++)\n f1(i);\n return 0;\n}\n\nHere is the output captured on Nehalem, if we are\nonly interested in user level function calls.\n\n$ perf record -b any_call,u -e cycles:u branchy\n\n$ perf report -b --sort\u003dsymbol\n 52.34% [.] main [.] f1\n 24.04% [.] f1 [.] f3\n 23.60% [.] f1 [.] f2\n 0.01% [k] _IO_new_file_xsputn [k] _IO_file_overflow\n 0.01% [k] _IO_vfprintf_internal [k] _IO_new_file_xsputn\n 0.01% [k] _IO_vfprintf_internal [k] strchrnul\n 0.01% [k] __printf [k] _IO_vfprintf_internal\n 0.01% [k] main [k] __printf\n\nAbout half (52%) of the call branches captured are from main()\n-\u003e f1(). The second half (24%+23%) is split in two equal shares\nbetween f1() -\u003e f2(), f1() -\u003ef3(). The output is as expected\ngiven the code.\n\nIt should be noted, that using -b in perf record does not\neliminate information in the perf.data file. Consequently, a\ntypical profile can also be obtained by perf report by simply\nnot using its -b option.\n\nIt is possible to sort on branch related columns:\n\n - dso_from, symbol_from\n - dso_to, symbol_to\n - mispredict\n\nSigned-off-by: Roberto Agostino Vitillo \u003cravitillo@lbl.gov\u003e\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\nCc: peterz@infradead.org\nCc: acme@redhat.com\nCc: robert.richter@amd.com\nCc: ming.m.lin@intel.com\nCc: andi@firstfloor.org\nCc: asharma@fb.com\nCc: vweaver1@eecs.utk.edu\nCc: khandual@linux.vnet.ibm.com\nCc: dsahern@gmail.com\nLink: http://lkml.kernel.org/r/1328826068-11713-14-git-send-email-eranian@google.com\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "bdfebd848f2a14e639031a0b0e61d7c7ee5e5fd2", "tree": "8ebcc7afda6b506dcd22d44bccdbd925c02b6768", "parents": [ "b5387528f31d98acedf06e930554b563d87e2383" ], "author": { "name": "Roberto Agostino Vitillo", "email": "ravitillo@lbl.gov", "time": "Thu Feb 09 23:21:02 2012 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Mar 09 08:26:05 2012 +0100" }, "message": "perf record: Add support for sampling taken branch\n\nThis patch adds a new option to enable taken branch stack\nsampling, i.e., leverage the PERF_SAMPLE_BRANCH_STACK feature\nof perf_events.\n\nThere is a new option to active this mode: -b.\nIt is possible to pass a set of filters to select the type of\nbranches to sample.\n\nThe following filters are available:\n\n -

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next\n\nUSB: Gadget: changes for 3.4\n\nThis merge is rather big. Here\u0027s what it contains:\n\nFor am5536udc we have just simple coding style fixes. Nothing that has any\npotential to cause any issues going forward.\n\nWith mv_udc, there\u0027s only one single change removing an unneeded NULL check.\n\nat91_udc also only saw a single change this merge window, and that\u0027s only\nremoving a duplicated header.\n\nThe Renesas controller has a few more involved changes. Support for SUDMAC was\nadded, there\u0027s now a special handling of IRQ resources for when the IRQ line is\nshared between Renesas controller and SUDMAC, we also had a bug fix where\nRenesas controller would sleep in atomic context while doing DMA transfers from\na tasklet. There were also a set of minor cleanups.\n\nThe FSL UDC also had a scheduling in atomic context bug fix, but that\u0027s all.\n\nThanks to Sebastian, the dummy_hcd now works better than ever with support for\nscatterlists and streams. Sebastian also added SuperSpeed descriptors to the\nserial gadgets.\n\nThe highlight on this merge is the addition of a generic API for mapping and\nunmapping usb_requests. This will avoid code duplication on all UDC controllers\nand also kills all the defines for DMA_ADDR_INVALID which UDC controllers\nsprinkled around. A few of the UDC controllers were already converted to use\nthis new API.\n\nConflicts:\n\tdrivers/usb/dwc3/gadget.c\n" }, { "commit": "1c1bc9223387dacc48eb2b61b0baabe7e9cf47f6", "tree": "873357b11c3423f2b8798b0c9e8e5ac18735db66", "parents": [ "cfbd70c17c4535e64be92ea442a2a45078a18184" ], "author": { "name": "Prashanth Nageshappa", "email": "prashanth@linux.vnet.ibm.com", "time": "Tue Feb 28 09:43:01 2012 +0530" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Wed Feb 29 18:29:46 2012 -0300" }, "message": "perf probe: Ensure offset provided is not greater than function length without DWARF info too\n\nThe \u0027perf probe\u0027 command allows kprobe to be inserted at any offset from\na function start, which results in adding kprobes to unintended\nlocation.
