This is a repost to LKML of the patches I sent to the linux-perf-users mailing
list.
I am reposting it to lkml per Arnaldo Carvalho's request.
The following is the jit library for the callbacks to capture the jit
code information. This version is just for test purposes. It causes
a remapping
. The following patches are dependent on this patch.

This patch adds a PR_TASK_PERF_UEVENT prctl call which can be used by
any process to inject custom data into perf data stream as a new
PERF_RECORD_UEVENT record
development. The goal is the jit library will only call for a remap when
it is really needed.

As far as I understand, you are providing access to a completely new

collects a program counter. It doesn't use the PMU counters nor the

In the current patch, the user specifies
d only one of the entries in the table will ever be used.
I think if we found the LFSR that was with in 2^10 of the desired value
that would be good enough. It would be within 1% of the minimum N the
user can specify. That would require a table with 2^14 entries. That
seems unreasonably large.
Anyway, the user controls how often sampling is done by setting N.

This is the update to the patch previously posted by Maynard Johnson as
PATCH 1/4. Add support to OProfile for profiling CELL. The patch was

Well most of the patch is simply cleaning up the

"pm_rtas_activat_signals routine cleanup" would be good.

In our earlier work on the PPU profiling patch, Benjamin Herrenschmidt
said that we should remove macros that are only used once and just put
the actual code in. That is why the macros were removed.
