      "message": "perf top: Fix counter name fixup when fallbacking to cpu-clock\n\nIn 40491eaa \"perf top: Update event name when falling back to cpu-clock\"\nwe freed counter-\u003ename but didn\u0027t reset it to NULL, then when setting it\nto the result of event_name(), event_name() would use the cached value,\nwhich by now was overwritten and thus we got garbage or a zero lenght\nstring.\n\nFix it by just freeing and setting counter-\u003ename to NULL, this way\nevent_name() when called afterwards, will find the right counter name\nand cache it again.\n\nFound while trying \u0027cycles:pp\u0027 on a machine were :pp couldn\u0027t be\nhonoured. Probably the best fallback here is to tell the user that that\nlevel of precision is not available on the PMU and then go removing \u0027p\u0027,\nlevels of precision till we get to play \u0027cycles\u0027 and if even that fails,\n_then_ get to \u0027cpu-clock\u0027.\n\nBut that is the matter for another patch, this one just needs to fix the\ncaching issue, which in the end will show \u0027cpu-clock\u0027 when tools ask for\nthe event name being used, which clarifies things for the user, that\nwill see that \u0027cycles:pp\u0027 or whatever not support event is not being\nused, some sort of fallback happened.\n\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Namhyung Kim \u003cnamhyung@gmail.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nLink: http://lkml.kernel.org/n/tip-w1neie2dqli89we1bzwkf4id@git.kernel.org\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n"

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"

      "message": "perf inject: Fix broken perf inject -b\n\nperf inject -b was broken. It would not inject any build_id into the\nstream. Furthermore, it would strip samples from the stream.\n\nThe reason was a missing initialization of the event attribute\nstructure. The perf_tool.tool.attr() callback was pointing to a simple\nrepipe. But there was no initialization of the internal data structures\nto keep track of events and event ids. That later caused event id\nlookups to fail, and sample would get removed.\n\nThe patch simply adds back the call to perf_event__process_attr() to\ninitialize the evlist structure and now build_ids are again injected.\n\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/1337081295-10303-2-git-send-email-eranian@google.com\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n"
