Ok, below is a patch which updates the ppc64 stuff. This fixes a
problem which meant it didn't even build before, but also does a bunch
of stuff: it mangles the ppc64 files to be closer in layout to the
i386 version, it fixes up the syscall entry points, and adds a
callback to pfm_handle_work() (I *think* it's in the right place). I
think it's still quite a long way from actually working, but it's
closer.
A couple of other questions:
- do you have an up-to-date version of the little
self_standalone test program you send me a while ago - the one I have
is still expecting perfmonctl() instead of individual syscalls
- where can I get the current version of the perfmon
specification? I've poked around on the perfmon site, but can't find
it.
