The oprofile build was broken on powerpc since version 0.9.8. This was detected in several autobuilds, like http://autobuild.buildroot.net/results/6f6c02d18495907d50fcdfc6003ac20d493c55fe/ Thomas Petazzoni had some fixes pending in his own tree, and this patch is partially based on this work (credits to him). Here is an overview: - I took over (and fixed) the oprofile.mk changes, except for the powerpc- specific part. For powerpc, there is a new dependency to libpfm4. - I reimported those Yocto patches that were specific to the ppc build issues, but left out the other ones. Those can be added in separate commits.

OProfile is a system-wide profiler for Linux systems,
|
|
capable of profiling all running code at low overhead.
|
|
OProfile is released under the GNU GPL.
|
|
|
|
It consists of a kernel driver and a daemon for collecting
|
|
sample data, and several post-profiling tools for turning
|
|
data into information.
|
|
|
|
OProfile leverages the hardware performance counters of the
|
|
CPU to enable profiling of a wide variety of interesting
|
|
statistics, which can also be used for basic time-spent
|
|
profiling. All code is profiled: hardware and software
|
|
interrupt handlers, kernel modules, the kernel, shared
|
|
libraries, and applications.
