Summary: Version 1.8, 2001-01-23 - Added preliminary interrupt-mode support to virtual perfctrs. Currently for P6 only, and the local APIC must have been enabled. Tested on 2.4.0-ac10 with CONFIG_X86_UP_APIC=y. When an i-mode vperfctr interrupts on overflow, the counters are suspended and a user-specified signal is sent to the process. The user's signal handler can read the trap pc from the mmap:ed vperfctr, and should then issue an IRESUME ioctl to restart the counters. The next version will support buffering and automatic restart. / Mikael Pettersson - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
