Showing better error message in case we fail to open counters due to the EBUSY error. If we detect oprofile daemon process running, we now display following message for EBUSY error: $ perf record ls Error: The PMU counters are busy/taken by another profiler. We found oprofile daemon running, please stop it and try again. In case oprofiled was not detected the current error message stays: $ perf record ls Error: The sys_perf_event_open() syscall returned with 16 (Device or resource busy) for event (cycles). /bin/dmesg may provide additional information. No CONFIG_PERF_EVENTS=y kernel support configured? Also changing PERF_FLAG_FD_CLOEXEC detection code not to display error in case of EBUSY error, as it currently does: $ perf record ls Error: perf_event_open(..., PERF_FLAG_FD_CLOEXEC) failed with unexpected error 16 (Device or resource busy) perf_event_open(..., 0) failed unexpectedly with error 16 (Device or resource busy) The PMU counters are busy/taken by another profiler.

Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where the Makefile lives and then we place the headers in subdirs. For example, all the fs-related stuff goes to tools/lib/api/fs/ from which we get libapikfs.a (acme got almost the naming he wanted :-)) and we link it into the tools which need it - in this case perf and tools/vm/page-types. acme: "Looking at the implementation, I think some tools can even link directly to the .o files, avoiding the .a file altogether. But that is just an optimization/finer granularity tools/lib/ cherrypicking that toolers can make use of." Fixup documentation cleaning target while at it.

'next_pow2()' only works for 'unsigned int' but the argument is 'unsigned long'. Checking for values less than (1 << 31) ensures that 'next_pow2()' is not passed a value out of range but lets anything else go through unvalidated. As a result mmap_pages of zero is used e.g. perf record -v -m2147483649 uname mmap size 0B failed to mmap with 22 (Invalid argument) Fixed: perf record -m2147483649 uname rounding mmap pages size to 17592186044416 bytes (4294967296 pages) Invalid argument for --mmap_pages/-m Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1386595120-22978-4-git-send-email-adrian.hunter@intel.comSigned-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Building perf for android fails because it can't find the definition of struct winsize. This definition is in termios.h, so I add this header to util.h to solve the problem. It is missed by commit '2c803e52' which moves get_term_dimensions() from builtin-top.c to util.c, but missed to move termios.h header.

One of the reasons 'perf test' is failing on Power appears to be due to a bug in isupper(). isupper(c) and islower(c) should be checking 'c' against the mask 0x20. Instead they are checking sane_ctype[c] which causes isupper() to be true for lower case letters.

perf is currently including magic.h directly from the kernel. If the glibc magic.h is also included, this leads to warnings that the constants are redefined. This happens on some systems (e.g. Android). Redefinition errors on Android: In file included from util/util.h:79:0, from util/cache.h:5, from util/abspath.c:1: util/../../../include/linux/magic.h:5:0: error: "AFFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:53:0: note: this is the location of the previous definition util/../../../include/linux/magic.h:19:0: error: "EFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:61:0: note: this is the location of the previous definition util/../../../include/linux/magic.h:26:0: error: "HPFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:67:0: note: this is the location of the previous definition Only two constants from magic.h are used by perf (DEBUGFS_MAGIC and SYSFS_MAGIC). This fix provides a wrapper for magic.h that includes only these constants instead of including the kernel header file directly.
