An updated version of the UP-APIC patch for Intel P6 processors is now available at: http://www.csd.uu.se/~mikpe/linux/upapic/ The current version is intended for 2.4.0-test12 final. This version is based on Ingo Molnar's upapic-2.4.0-test9-F8 patch, with add-on patches from Maciej W. Rozycki and myself. I'm intending to maintain it until it gets into 2.4 or 2.5. I've used it since test10-pre and believe it to be safe for general use, but more testers are welcome. For those unfamiliar with the patch: - It enables the local APIC found in most P6 family processors, even on UP systems which often keep it disabled. - The NMI watchdog now works on UP systems too. This is interesting primarily for kernel hackers wishing to debug lockups. - A properly enabled local APIC is a prerequisite for interrupt- driven use of the performance-monitoring counters. /Mikael - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
