Hello All,
Just a quick question: Why does this function (ipi_nmi_handler) execute a atomic_load_acq_int(&ipi_nmi_pending). Following this it calls atomic_clear_int to clear itself out of this mask. I can't think of why the CPU would reorder these instructions knowing there is a dependency here. Also, since FreeBSD has masks (like ipi_nmi_pending), has there been any work on extending this beyond 64 CPUs? Thanks Ravi _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
