I notice on the T61 that this disables MWAIT for C2 and C3, but not for C1. While I know that the issue at hand is C2 and C3, it seems misleading to boot with idle=nomwait and see that MWAIT is used for C1. I think we should extend this param to also apply to the MWAIT use for C1. I don't think the difference between MWAIT and HALT in C1 will be signficant, given that this is a debugging-tool/bug workaround. thanks, -Len [lenb@t61 ~]$ grep . /sys/devices/system/cpu/cpu*/cpuidle/*/* /sys/devices/system/cpu/cpu0/cpuidle/state0/desc:<null> /sys/devices/system/cpu/cpu0/cpuidle/state0/latency:0 /sys/devices/system/cpu/cpu0/cpuidle/state0/name:<null> /sys/devices/system/cpu/cpu0/cpuidle/state0/power:4294967295 /sys/devices/system/cpu/cpu0/cpuidle/state0/time:24103 /sys/devices/system/cpu/cpu0/cpuidle/state0/usage:27 /sys/devices/system/cpu/cpu0/cpuidle/state1/desc:ACPI FFH INTEL MWAIT 0x0 /sys/devices/system/cpu/cpu0/cpuidle/state1/latency:1 /sys/devices/system/cpu/cpu0/cpuidle/state1/name:C1 /sys/devices/system/cpu/cpu0/cpuidle/state1/power:1000 /sys/devices/system/cpu/cpu0/cpuidle/state1/time:0 /sys/devices/system/cpu/cpu0/cpuidle/state1/usage:0 /sys/devices/system/cpu/cpu0/cpuidle/state2/desc:ACPI IOPORT 0x1014 /sys/devices/system/cpu/cpu0/cpuidle/state2/latency:1 /sys/devices/system/cpu/cpu0/cpuidle/state2/name:C2 /sys/devices/system/cpu/cpu0/cpuidle/state2/power:500 /sys/devices/system/cpu/cpu0/cpuidle/state2/time:21905 /sys/devices/system/cpu/cpu0/cpuidle/state2/usage:569 /sys/devices/system/cpu/cpu0/cpuidle/state3/desc:ACPI IOPORT 0x1015 /sys/devices/system/cpu/cpu0/cpuidle/state3/latency:17 /sys/devices/system/cpu/cpu0/cpuidle/state3/name:C3 /sys/devices/system/cpu/cpu0/cpuidle/state3/power:250 /sys/devices/system/cpu/cpu0/cpuidle/state3/time:284208055 /sys/devices/system/cpu/cpu0/cpuidle/state3/usage:53661 /sys/devices/system/cpu/cpu1/cpuidle/state0/desc:<null> /sys/devices/system/cpu/cpu1/cpuidle/state0/latency:0 /sys/devices/system/cpu/cpu1/cpuidle/state0/name:<null> /sys/devices/system/cpu/cpu1/cpuidle/state0/power:4294967295 /sys/devices/system/cpu/cpu1/cpuidle/state0/time:237647 /sys/devices/system/cpu/cpu1/cpuidle/state0/usage:25 /sys/devices/system/cpu/cpu1/cpuidle/state1/desc:ACPI FFH INTEL MWAIT 0x0 /sys/devices/system/cpu/cpu1/cpuidle/state1/latency:1 /sys/devices/system/cpu/cpu1/cpuidle/state1/name:C1 /sys/devices/system/cpu/cpu1/cpuidle/state1/power:1000 /sys/devices/system/cpu/cpu1/cpuidle/state1/time:0 /sys/devices/system/cpu/cpu1/cpuidle/state1/usage:0 /sys/devices/system/cpu/cpu1/cpuidle/state2/desc:ACPI IOPORT 0x1014 /sys/devices/system/cpu/cpu1/cpuidle/state2/latency:1 /sys/devices/system/cpu/cpu1/cpuidle/state2/name:C2 /sys/devices/system/cpu/cpu1/cpuidle/state2/power:500 /sys/devices/system/cpu/cpu1/cpuidle/state2/time:32354 /sys/devices/system/cpu/cpu1/cpuidle/state2/usage:1042 /sys/devices/system/cpu/cpu1/cpuidle/state3/desc:ACPI IOPORT 0x1015 /sys/devices/system/cpu/cpu1/cpuidle/state3/latency:17 /sys/devices/system/cpu/cpu1/cpuidle/state3/name:C3 /sys/devices/system/cpu/cpu1/cpuidle/state3/power:250 /sys/devices/system/cpu/cpu1/cpuidle/state3/time:294127944 /sys/devices/system/cpu/cpu1/cpuidle/state3/usage:65794 -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
