--- Comment #14 from Stéphane Lesimple <stephane_free...@lesimple.fr> --- Some new data points: The oldest version I could try, 8.0-RELEASE, behaves the same with C2 as in any more recent version (up to HEAD). This problem was hidden before due to the cx_lowest default always being C1 up to 11.0R. I also noticed that when C2 is set as cx_lowest, C1 is not used at all. Another interesting behavior is that the cx_usage_counters increases 10 times faster with C2 than with C1. It might also be interesting to note that C3 is ignored even if advertised as supported (which is probably irrelevant to this bug). # sysctl dev.cpu.0.cx_lowest=C1 ; sleep 10 ; sysctl dev.cpu.0.cx_usage_counters dev.cpu.0.cx_lowest: C1 -> C1 dev.cpu.0.cx_usage_counters: 1192 0 0 # sysctl dev.cpu.0.cx_lowest=C2 ; sleep 10 ; sysctl dev.cpu.0.cx_usage_counters dev.cpu.0.cx_lowest: C1 -> C2 dev.cpu.0.cx_usage_counters: 0 11122 0 # sysctl dev.cpu.0.cx_lowest=C3 ; sleep 10 ; sysctl dev.cpu.0.cx_usage_counters dev.cpu.0.cx_lowest: C2 -> C3 dev.cpu.0.cx_usage_counters: 0 11048 0 -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-acpi@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to "freebsd-acpi-unsubscr...@freebsd.org"
