OProfile 0.9.1 has been released. OProfile is still in alpha,
but has been proven stable for many users.

New features
------------

Support for MIPS 24K performance counters.

Bug fixes
---------

Compilation with older GNU libc versions and GCC 2.95.x has been fixed.

An assertion caused by ARM kernel binary layout has been avoided, and
ARM kernel results are fixed.

Attempting to use "opannotate -a -o" gives an error.

The 2.4 kernel module now compiles with GCC 3.4.

Known problems
--------------

On IA-64, some firmware revisions cause problems with OProfile (bug #931883).

Power management on laptops can be incompatible with OProfile in 2.4 (bug #554927).

Many Alpha ev67 events do not work (bug #931875).

A few Pentium IV events are not supported (bug #841099).

The pre-emptable kernel option is not supported in 2.4 (bug #478516).

nosmp is not supported in kernels before 2.4.10 (bug #463087).

For 2.2 kernels, the module must be compiled as the same user
that owns the kernel source tree.

With an AMD64 kernel, OProfile must be built in 64 bit mode due to lack
of kernel support.

opreport -c gives strange output for binaries without symbols.
