The acpi_perf driver should successfully adjust when things change at runtime. The other drivers have no way of knowing. > 4. One question.

I don't know but things should be getting better. -- Nate _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
