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.

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.

perf does not have networking related functionality, and the inclusion of these headers is one of the causes of compile failures for Android: https://lkml.org/lkml/2012/8/23/316 https://lkml.org/lkml/2012/8/28/293 So, remove them.

The perf_target__validate function is used to check given PID/TID/UID/CPU target options and warn if some combination is impossible. Also this can make some arguments of parse_target_uid() function useless as it is checked before the call via our new helper.
