If not, then we consider it a numeric array, and print the hex numbers of the characters instead. But it seems that '\n' fails the isprint() check! Add isspace() to the check as well, such that if all characters pass isprint() or isspace() it will assume the character array is a string.

This way we can associate a timeframe to any thread COMM, as long as PERF_SAMPLE_TIME samples are joined to COMM and fork events. As a result we should have more precise COMM sorted hists with seperated entries for pre and post exec time after a fork. 2) It also makes sure that a given COMM string is not duplicated but rather shared among the threads that refer to it. This way the threads COMM can be compared against pointer values from the sort infrastructure.

We recently restored the callchain requesting command line argument, -g, to not require a parameter ("dwarf" or "fp"), instead using a default ("fp" for now) and making the long option variant, --call-chain, be the one to be used when a different callchain collection method is preferred. The "struct perf_event_attr setup" test failed because we forgot to update the tests involving callchains, not switching from, '-g dwarf' to '--call-chain dwarf', making 'perf test' detect it: [root@sandy ~]# perf test -v 13 13: struct perf_event_attr setup : --- start --- running '/home/acme/libexec/perf-core/tests/attr/test-record-basic' running '/home/acme/libexec/perf-core/tests/attr/test-record-branch-any' <SNIP> running '/home/acme/libexec/perf-core/tests/attr/test-record-graph-default' running '/home/acme/libexec/perf-core/tests/attr/test-record-graph-dwarf' expected sample_type=12583, got 295 expected exclude_callchain_user=1, got 0 expected sample_stack_user=8192, got 0 FAILED '/home/acme/libexec/perf-core/tests/attr/test-record-graph-dwarf' - match failure ---- end ---- struct perf_event_attr setup: FAILED! [root@sandy ~]# Fix all of them now to use --call-chain when explicitely specifying a method. There is still work to do, as '-g fp', for instance, passed without problems. In that case 'perf test' saw no problems as the intercepted syscall got the bits as expected, i.e. the default is 'fp', but the fact that 'fp' may be an existing program and the specified workload would then be passed as a parameter to it is an usability problem that needs fixing.

Unfortunately 'perf top' does not show the reconfigured name, possibly because it caches ->comm[] values and does not recognize changes to them? Also clean up a few bits in builtin-bench.c while at it and reorganize the code and the output strings to be consistent. Use iterators to access the various arrays. Rename 'suites' concept to 'benchmark collection' and the 'bench_suite' to 'benchmark/bench'. The many repetitions of 'suite' made the code harder to read and understand.

This makes variable searching fail at the entry of functions which are mcount'ed. e.g.) Available variables at vfs_read @<vfs_read+0> (No matched variables) This patch adds additional location search at the function entry point to solve this issue, which tries to find the earliest address for the variable location. Note that this only works with function parameters (formal parameters) because any local variables should not exist on the function entry address (those are not initialized yet). With this patch, perf probe shows correct parameters if possible; # perf probe --vars vfs_read Available variables at vfs_read @<vfs_read+0> char* buf loff_t* pos size_t count struct file* file Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/20131011071025.15557.13275.stgit@udc4-manage.rcp.hitachi.co.jp Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
