Package: linux-tools-3.2 Version: 3.2.17-1 Severity: normal Dear Maintainer, When issuing "perf record -p <annoying_process_id> -g", I got "Fatal: failed to mmap with 22 (Invalid argument)". This is remedied by setting /proc/sys/kernel/perf_event_paranoid to -1 (I tested it with 0, and it still occurred).
perf record should state what sys.kernel.perf_event_paranoid should be set to in response to failure, instead of giving me such a useless error message. -- System Information: Debian Release: 7.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.2.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages linux-tools-3.2 depends on: ii libc6 2.13-37 ii libdw1 0.152-1+wheezy1 ii libelf1 0.152-1+wheezy1 ii libnewt0.52 0.52.14-10 ii libperl5.14 5.14.2-16 ii libpython2.7 2.7.3~rc2-2.1 ii libslang2 2.2.4-15 ii perl 5.14.2-16 ii python 2.7.3~rc2-1 Versions of packages linux-tools-3.2 recommends: ii linux-base 3.5 Versions of packages linux-tools-3.2 suggests: pn linux-doc-3.2 <none> -- no debconf information -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
