Adding support to return error information from parse_events function. Following struct will be populated by parse_events function on return: struct parse_events_error { int idx; char *str; char *help; }; where 'idx' is the position in the string where the parsing failed, 'str' contains dynamically allocated error string describing the error and 'help' is optional help string. The change contains reporting function, which currently does not display anything. The code changes to supply error data for specific event types are coming in next patches. However this is what the expected output is: $ sudo perf record -e 'sched:krava' ls event syntax error: 'sched:krava' \___ unknown tracepoint ... $ perf record -e 'cpu/even=0x1/' ls event syntax error: 'cpu/even=0x1/' \___ unknown term valid terms: pc,any,inv,edge,cmask,event,in_tx,ldlat,umask,in_tx_cp,offcore_rsp,config,config1,config2,name,period,branch_type ... $ perf record -e cycles,cache-mises ls event syntax error: '..es,cache-mises' \___ parser error ... The output functions cut the beginning of the event string so the error starts up to 10th character and cut the end of the string of it crosses the terminal width.

Instruction tracing will typically have access to information about the instruction being executed for a particular ip sample. Some of that information will be available in the 'flags' member of struct perf_sample. With the addition of transactions events synthesis to Instruction Tracing options, there is a need to be able easily to see the flags because they show whether the ip is at the start, commit or abort of a tranasaction. Consequently add an option to display the flags. The flags are "bcrosyiABEx" which stand for branch, call, return, conditional, system, asynchronous, interrupt, transaction abort, trace begin, trace end, and in transaction, respectively. Example using Intel PT: perf script -fip,time,event,sym,addr,flags ... 1288.721584105: branches:u: bo 401146 main => 401152 main 1288.721584105: transactions: x 0 401164 main 1288.721584105: branches:u: bx 40117c main => 40119b main 1288.721584105: branches:u: box 4011a4 main => 40117e main 1288.721584105: branches:u: bcx 401187 main => 401094 g ... 1288.721591645: branches:u: bx 4010c4 g => 4010cb g 1288.721591645: branches:u: brx 4010cc g => 401189 main 1288.721591645: transactions: 0 4011a6 main 1288.721593199: branches:u: b 4011a9 main => 4011af main 1288.721593199: branches:u: bo 4011bc main => 40113e main 1288.721593199: branches:u: b 401150 main => 40115a main 1288.721593199: transactions: x 0 401164 main 1288.721593199: branches:u: bx 40117c main => 40119b main 1288.721593199: branches:u: box 4011a4 main => 40117e main 1288.721593199: branches:u: bcx 401187 main => 40105e f ... 1288.722284747: branches:u: brx 401093 f => 401189 main 1288.722284747: branches:u: box 4011a4 main => 40117e main 1288.722284747: branches:u: bcx 401187 main => 40105e f 1288.722285883: transactions: bA 0 401071 f 1288.722285883: branches:u: bA 401071 f => 40116a main 1288.722285883: branches:u: bE 40116a main => 0 [unknown] 1288.722297174: branches:u: bB 0 [unknown] => 40116a main ...

It is assumed that AUX area decoding will synthesize events for consumption by other tools. At this time, the main use of AUX area tracing will be to capture instruction trace (aka processor trace) data. The nature of instruction tracing suggests the initial inclusion of options for "instructions" and "branches" events, but more could be added as needed.

Hook into session processing so that AUX area decoding can synthesize events transparently to the tools. The advantages of transparent decoding are that tools can be used directly with perf.data files containing AUX area tracing data, which is easier for the user and more efficient than having a separate decoding tool. This will work as follows: 1. Tools will feed auxtrace events to the decoder using perf_tool->auxtrace() (support for that still to come). 2. The decoder can process side-band events as needed due to the auxtrace->process_event() hook. 3. The decoder can deliver synthesized events into the event stream using perf_session__deliver_synth_event(). Note the expectation is that decoding will work on data that is time-ordered with respect to the per-cpu or per-thread contexts that were recorded.

Add support for reading from the AUX area tracing mmap and synthesizing AUX area tracing events. This patch introduces an abstraction for recording AUX area data. Recording is initialized by auxtrace_record__init() which is a weak function to be implemented by the architecture to provide recording callbacks. Recording is mainly handled by auxtrace_mmap__read() and perf_event__synthesize_auxtrace() but there are callbacks for miscellaneous needs including validating and processing user options, populating private data in auxtrace_info_event, and freeing the structure when finished.

When converting int values, perf first extractes it to a ulonglong, then feeds it to babeltrace as a signed value. For negative 32 bit values (for example, return values of failed syscalls), the extracted data should be something like 0xfffffffe (-2). It becomes a large int64 value. Babeltrace denies to insert it with bt_ctf_field_signed_integer_set_value() because it is larger than 0x7fffffff, the largest positive value a 32 bit int can be. This patch introduces adjust_signedness(), which fills high bits of ulonglong with 1 if the value is negative.

For big data files the size of data allocated for stream instance could get really high. It's needed to flush the data out of the stream once in a while. Unfortunately there's no size indication in the stream object, so we govern the flush based on the number of stored events. Current flush limit is set ot 100000 events.

Currently we store the data into single data strea/file. The cpu if data is stored within the event sample. The lttng puts the CPU number that belongs to the event into the packet context instead into the event. This patch makes sure that the trace produce by perf does look the same way. We now use one stream per-CPU. Having it all in one stream increased the total size of the resulting file. The test went from 416KiB (with perf_cpu event member) to 24MiB due to the required (and pointless) flush. With the per-cpu streams the total size went up to 588KiB.

Several fixes were needed to allow following builds: $ make tools/tmon $ make -C <kernelsrc> tools/perf $ make -C <kernelsrc>/tools perf - some of the tools (perf) use same make variables as in kernel build, unsetting srctree and objtree - using original $(O) for O variable - perf build does not follow the descend function setup invoking it via it's own make rule I tried the rest of the tools/Makefile targets and they seem to work now.

Introduce an 'alias' field to 'struct format_field' to be able to use alternative name for the field. It is initialized with same string pointer as 'name' field. The free logic checks the 'alias' pointer being reset by user and frees it. This will be handy when converting data into CTF, where each field within event needs to have a unique name (while this is not required for tracepoint). Converter can easily assign unique name into the format_field struct.

The first argument passed to find_probe_point_lazy() should be CU die, which will be passed to die_walk_lines() when lazy_line matches. Currently, when we probe with lazy_line pattern to file without function name, NULL pointer is passed and causes a segment fault. Can be reproduced as following: $ perf probe -k vmlinux --add='fs/super.c;s->s_count=1;' [ 1958.984658] perf[1020]: segfault at 10 ip 00007fc6e10d8c71 sp 00007ffcbfaaf900 error 4 in libdw-0.161.so[7fc6e10ce000+34000] Segmentation fault After this patch: $ perf probe -k vmlinux --add='fs/super.c;s->s_count=1;' Added new event: probe:_stext (on @fs/super.c) You can now use it in all perf tools, such as: perf record -e probe:_stext -aR sleep 1 Signed-off-by: NHe Kuang <hekuang@huawei.com> Tested-by: NArnaldo Carvalho de Melo <acme@redhat.com> Acked-by: NMasami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1428925290-5623-3-git-send-email-hekuang@huawei.comSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

If we use lazy matching, it failed to open a souce file if perf command is invoked outside of compilation directory: $ perf probe -a '__schedule;clear_*' Failed to open kernel/sched/core.c: No such file or directory Error: Failed to add events. (-2) OTOH, other commands like "probe -L" can solve the souce directory by themselves. Let's make it possible for lazy matching too!
