Subject: perfctr-3.1 released

perfctr-3.1 is now available at the usual place:
http://www.csd.uu.se/~mikpe/linux/perfctr/3.x/

This is a snapshot of the new driver that is being
submitted for inclusion in the Linux 2.5 kernel.

This version won't compile in 2.4 kernels. I hope to add
that capability back later, in a way that isn't visible
in the base code.

Changes since 3.0-pre1, the previously announced version:

Version 3.1, 2002-10-31
- Removed hooks for 2.4 compatibility code in the driver.
  The driver will currently only compile in 2.5 kernels.

Version 3.0.2, 2002-10-31
- Removed the notion that all high-level drivers are accessible
  via <linux/perfctr.h> and a single system call. Since there is
  only one high-level driver currently, vperfctr, there is one
  vperfctr-specific #include in <linux/vperfctr.h>, and one
  vperfctr-specific system call sys_vperfctr(). Lots of code
  cleanups. Patch kits updated due to interface name changes.

Version 3.0.1, 2002-10-31
- Made the driver safe for preemptible kernels.

Version 3.0, 2002-10-29
- Updated etc/mk-patchkit.sh. The "kernel changes" part is now
  2/4 instead of 4/4. Moved include/asm-i386/perfctr.h from the
  "x86" part to the "core" part, to ensure that the kernel can
  be compiled with only "core" + "kernel changes" applied.
  Changed part naming from ".NR-name" to "-NR.name" to avoid
  confusing the part number with perfctr's version number.

Version 3.0-pre3, 2002-10-26
- Migrated x86.c's per_cpu_cache to the 2.5 per_cpu() framework.
- Moved the perfctr config option to just before 'Kernel hacking'
  in the 2.4 kernel patch, for consistency with the 2.5 patch.
- Added notes in README and INSTALL that the kernel must be
  configured with CONFIG_PREEMPT disabled.

Version 3.0-pre2, 2002-10-24
- Fixed the configuration entry to not be hidden in the Bus options menu.
