perf symbols: Check the right return variable

2010-03-15T16:06:12+00:00

commit 37fe5fcb7a5b5235c8b71bf5469ce4c7246e3fab upstream.

In function dso__split_kallsyms(), curr_map saves the return value
of map__new2. So check it instead of var map after the call returns.

perf probe: Init struct probe_point and set counter correctly

2010-02-22T10:42:27+00:00

Clear struct probe_point before using it in
show_perf_probe_events(), and set pp->found counter correctly in
synthesize_perf_probe_point(). Without this initialization,
clear_probe_point() will free random addresses.

perf: Fix hypervisor sample reporting

2010-02-09T09:52:40+00:00

cpumode bits are defined as such:

 #define PERF_RECORD_MISC_KERNEL                 (1 << 0)
 #define PERF_RECORD_MISC_USER                   (2 << 0)
 #define PERF_RECORD_MISC_HYPERVISOR             (3 << 0)

We need to compare against the complete value of cpumode,
otherwise hypervisor samples get incorrectly attributed as
userspace.

perf kmem: Increase "Hit" column length

2010-01-20T06:20:07+00:00

It's fairly easy to overflow the "Hit" column with just few
seconds of tracing so increase the column length to avoid broken
formatting.

perf timechart: Use tid not pid for COMM change

2010-01-17T06:16:36+00:00

A process that changes its comm field, does this on a per kernel
task struct basis. The timechart tool used, incorrectly, the pid
to track this, and should have used the tid instead...

perf tools: Check if /dev/null can be used as the -o gcc argument

2010-01-13T09:08:12+00:00

At least on Debian PARISC64, using:

acme@parisc:~/git/linux-2.6-tip$ gcc -v
Using built-in specs.
Target: hppa-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Debian
4.3.4-6' --with-bugurl=file:///usr/share/doc/gcc-4.3/README.Bugs
--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr
--enable-shared --enable-multiarch --enable-linker-build-id --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.3 --program-suffix=-4.3 --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr --disable-libssp --enable-checking=release --build=hppa-linux-gnu --host=hppa-linux-gnu --target=hppa-linux-gnu Thread model: posix gcc version 4.3.4 (Debian 4.3.4-6)

there are issues about using 'gcc -o /dev/null':

/usr/bin/ld: final link failed: File truncated
collect2: ld returned 1 exit status

So we test that and use /dev/null in environments where it
works, while using an .INTERMEDIATE file on those where it can't
be used, so that the .perf.dev.null file can be used instead and
then deleted when make exits.
