Subject: perfctr-2.4.0-pre1 released

perfctr-2.4.0-pre1 is now available at the usual place:
http://www.csd.uu.se/~mikpe/linux/perfctr/

This release contains the initial implementation of the new
remote-control API for per-process perfctrs. This API is
intended to be much simpler for the kernel code than the old
remote-control API that existed before perfctr-1.5.

While I think the new code is safe, this release is really only
meant for those wanting to experiment with the new API.

Once this API extension stabilises, the 2.4.x perfctr series will
essentially be in feature-freeze, with updates only for bug fixes
and newer 2.2/2.4 Linux kernels.

Version 2.4.0-pre1, 2002-08-12
- The kernel driver has an initial implementation of a new
  remote-control API for virtual per-process perfctrs.
  A monitor process may access a target process' perfctrs via
  open(), mmap(), and ioctl() on the target's /proc/pid/perfctr.
  For open() and ioctl(), the monitor must hold the target under
  ptrace ATTACH control. The user-space library and examples have
  not been updated for the new API.
