--- NEW FILE: oprofile-0.5.3 ---

OProfile 0.5.3 has been released. OProfile is still in alpha,
but has been proven stable for many users.

Release notes
-------------

For 2.2 kernels, the module must be compiled as the same user
that owns the kernel source tree.
 
nosmp is not supported in kernels before 2.4.10 (bug #463087).

The pre-emptable kernel option is not supported in 2.4 (bug #478516).
 
Power management on laptops can be incompatible with OProfile in 2.4 (bug #554927).

The utilities op_start, op_stop, op_dump, and op_session have been removed,
as threatened in the last three releases. opcontrol is the replacement.

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

The annotated source output has changed so that each line is prefixed by the
counts, and the header is now a footer. This maintains the line numbering
in the annotated output. The same change has been done for annotated assembly
output.

The daemon now handles --no-vmlinux with 2.4 kernels.

Bug fixes
---------

Some sanity checking on the minimum event count has been re-introduced, to
help guard against typos locking up the machine (bug #715923)

Some serious problems with hyper-threaded Pentium 4s have been fixed.

Some Hammer and i386 event descriptions have been fixed.

An IA-64 compile problem has been fixed.

Make opcontrol --ctrX-event=none work properly.

sparc and sparc64 in 2.5 are theoretically supported.

In 2.4, the watermark size is now proportional to the buffer size.

We were doing a sanity check on matching CPU speeds. This makes
no sense and has been removed.

A rare race that could cause a sample file to be corrupted when
running oprofpp has been fixed.

More STL patterns are matched by --smart-demangle.
