and has been used for years\n in Fedora and RHEL kernels. This version is much rewritten, reviews\n from PeterZ, Oleg and myself shaped the end result.\n\n This tree includes uprobes support in \u0027perf probe\u0027 - but SystemTap\n (and other tools) can take advantage of user probe points as well.\n\n Sample usage of uprobes via perf, for example to profile malloc()\n calls without modifying user-space binaries.\n\n First boot a new kernel with CONFIG_UPROBE_EVENT\u003dy enabled.\n\n If you don\u0027t know which function you want to probe you can pick one\n from \u0027perf top\u0027 or can get a list all functions that can be probed\n within libc (binaries can be specified as well):\n\n\t$ perf probe -F -x /lib/libc.so.6\n\n To probe libc\u0027s malloc():\n\n\t$ perf probe -x /lib64/libc.so.6 malloc\n\tAdded new event:\n\tprobe_libc:malloc (on 0x7eac0)\n\n You can now use it in all perf tools, such as:\n\n\tperf record -e probe_libc:malloc -aR sleep 1\n\n Make use of it to create a call graph (as the flat profile is going to\n look very boring):\n\n\t$ perf record -e probe_libc:malloc -gR make\n\t[ perf record: Woken up 173 times to write data ]\n\t[ perf record: Captured and wrote 44.190 MB perf.data (~1930712\n\n\t$ perf report | less\n\n\t 32.03% git libc-2.15.so [.] malloc\n\t |\n\t --- malloc\n\n\t 29.49% cc1 libc-2.15.so [.] malloc\n\t |\n\t --- malloc\n\t |\n\t |--0.95%-- 0x208eb1000000000\n\t |\n\t |--0.63%-- htab_traverse_noresize\n\n\t 11.04% as libc-2.15.so [.] malloc\n\t |\n\t --- malloc\n\t |\n\n\t 7.15% ld libc-2.15.so [.] malloc\n\t |\n\t --- malloc\n\t |\n\n\t 5.07% sh libc-2.15.so [.] malloc\n\t |\n\t --- malloc\n\t |\n\t 4.99% python-config libc-2.15.so [.] malloc\n\t |\n\t --- malloc\n\t |\n\t 4.54% make libc-2.15.so [.] malloc\n\t |\n\t --- malloc\n\t |\n\t |--7.34%-- glob\n\t | |\n\t | |--93.18%-- 0x41588f\n\t | |\n\t | --6.82%-- glob\n\t | 0x41588f\n\n\t ...\n\n Or:\n\n\t$ perf report -g flat | less\n\n\t# Overhead Command Shared Object Symbol\n\t# ........ ............. ............. ..........\n\t#\n\t 32.03% git libc-2.15.so [.] malloc\n\t 27.19%\n\t malloc\n\n\t 29.49% cc1 libc-2.15.so [.] malloc\n\t 24.77%\n\t malloc\n\n\t 11.04% as libc-2.15.so [.] malloc\n\t 11.02%\n\t malloc\n\n\t 7.15% ld libc-2.15.so [.] malloc\n\t 6.57%\n\t malloc\n\n\t ...\n\n The core uprobes design is fairly straightforward: uprobes probe\n points register themselves at (inode:offset) addresses of\n libraries/binaries, after which all existing (or new) vmas that map\n that address will have a software breakpoint injected at that address.\n vmas are COW-ed to preserve original content. The probe points are\n kept in an rbtree.\n\n If user-space executes the probed inode:offset instruction address\n then an event is generated which can be recovered from the regular\n perf event channels and mmap-ed ring-buffer.\n\n Multiple probes at the same address are supported, they create a\n dynamic callback list of event consumers.\n\n The basic model is further complicated by the XOL speedup: the\n original instruction that is probed is copied (in an architecture\n specific fashion) and executed out of line when the probe triggers.\n The XOL area is a single vma per process, with a fixed number of\n entries (which limits probe execution parallelism).\n\n The API: uprobes are installed/removed via\n /sys/kernel/debug/tracing/uprobe_events, the API is integrated to\n align with the kprobes interface as much as possible, but is separate\n to it.\n\n Injecting a probe point is privileged operation, which can be relaxed\n by setting perf_paranoid to -1.\n\n You can use multiple probes as well and mix them with kprobes and\n regular PMU events or tracepoints, when instrumenting a task.\"\n\nFix up trivial conflicts in mm/memory.c due to previous cleanup of\nunmap_single_vma().\n\n* \u0027perf-uprobes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (21 commits)\n perf probe: Detect probe target when m/x options are absent\n perf probe: Provide perf interface for uprobes\n tracing: Fix kconfig warning due to a typo\n tracing: Provide trace events interface for uprobes\n tracing: Extract out common code for kprobes/uprobes trace events\n tracing: Modify is_delete, is_return from int to bool\n uprobes/core: Decrement uprobe count before the pages are unmapped\n uprobes/core: Make background page replacement logic account for rss_stat counters\n uprobes/core: Optimize probe hits with the help of a counter\n uprobes/core: Allocate XOL slots for uprobes use\n uprobes/core: Handle breakpoint and singlestep exceptions\n uprobes/core: Rename bkpt to swbp\n uprobes/core: Make order of function parameters consistent across functions\n uprobes/core: Make macro names consistent\n uprobes: Update copyright notices\n uprobes/core: Move insn to arch specific structure\n uprobes/core: Remove uprobe_opcode_sz\n uprobes/core: Make instruction tables volatile\n uprobes: Move to kernel/events/\n uprobes/core: Clean up, refactor and improve the code\n ...\n" }, { "commit": "299c345208ae15fbc1e1c96dc1b6ac61e4e5da10", "tree": "daa53fb34d1ee230a6f73546702cb1f22bcfe21d", "parents": [ "444d28663936e286c752f05feca44d6041b1fce4" ], "author": { "name": "Stephane Eranian", "email": "eranian@google.com", "time": "Tue May 15 13:28:15 2012 +0200" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Tue May 22 13:03:54 2012 -0300" }, "message": "perf buildid-list: Work better with pipe mode\n\nIn order for perf buildid-list to work with pipe-mode files, it needs to\nprocess buildids and event attr structs.\n\n$ perf record -o - noploop 2 | ./perf inject -b | perf buildid-list -i - -H\nnoploop for 2 seconds\n[ perf record: Woken up 1 times to write data ]\n[ perf record: Captured and wrote 0.084 MB - (~3678 samples) ]\n0000000000000000000000000000000000000000 [kernel.kallsyms]\n3a0d0629efe74a8da3eeba372cdbd74ad9b8f5d5 /usr/local/bin/noploop\n\nThe reason [kernel.kallsyms] shows a 0 build-id comes from the\nway buildids are injected in the stream.\n\nThe buildid for the kernel is provided by a BUILD_ID record.
