[PATCH] Please test SMP changes
[ Bcc'd to various arch mailing lists ] Please test the patch at http://www.FreeBSD.org/~jhb/patches/smp.patch You can apply it to a sys/ check out by using patch -p6. It moves the setting of mp_maxid into a separate function (cpu_mp_setmaxid()) that is called before loader tunables so that UMA and others can use it. cpu_mp_probe() is now called at SI_SUB_CPU / SI_ORDER_SECOND like it used to be. This is necessay to re-enable the ACPI module on i386. I have tested it on i386 but not on other archs. Please be sure to test that a normal SMP kernel works as well as booting an SMP kernel with 'kern.smp.disabled'. cpu_mp_probe() is no longer called if SMP is disabled in the loader using the tunable. Thanks. -- John Baldwin [EMAIL PROTECTED]http://www.FreeBSD.org/~jhb/ Power Users Use the Power to Serve! - http://www.FreeBSD.org/ ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to [EMAIL PROTECTED]

Thanks. What all do I need to adjust on my end, other patches? I took 'device acpi' out of my kernel, but if I try to boot with the acpi module loaded, the kernel still uses MPTable for interrupts: Copyright (c) 1992-2003 The FreeBSD Project.

I took 'device acpi' out of my kernel, but if I try to boot with the acpi module loaded, the kernel still uses MPTable for interrupts: No, please. Don't disable ACPI. This is not all the patches to do that. Mostly I just want to mkae sure that I don't break SMP probing on all the different architectures. i386 seems to be working fine, I'm primarily after testing on the other archs: alpha, amd64, ia64, and sparc64 in particular to make sure I didn't break SMP probing on those archs. To be clear: ACPI needs _more_ patches in addition to smp.patch before it will work as a module again. -- John Baldwin [EMAIL PROTECTED]http://www.FreeBSD.org/~jhb/ Power Users Use the Power to Serve! - http://www.FreeBSD.org/ ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to [EMAIL PROTECTED]
