This is almost *exactly* the same as on my very cheap'n stupid HP/Compaq
desktop P4 HT which doesn't support ACPI C2/C3 at all despite proper support
by other P4 HT desktop machines (missing _CST ACPI object in the DSDT,
as confirmed after messing with Intel's DSDT decompiler):
# cat /proc/acpi/processor/CPU?/*
processor id: 0
acpi id: 1
bus mastering control: no
power management: no
throttling control: yes
limit interface: yes
active limit: P0:T0
user limit: P0:T0
thermal limit: P0:T0
active state: C1
max_cstate: C8
bus master activity: 00000000
states:
*C1: type[C1] promotion[--] demotion[--] latency[000] usage[00000000] duration[00000000000000000000]
state count: 8
active state: T0
states:
*T0: 00%
T1: 12%
T2: 25%
T3: 37%
T4: 50%
T5: 62%
T6: 75%
T7: 87%
Note that
max_cstate: C8
can be considered a bug (this is a C state init value from an ACPI define
mistakenly left unchanged in case of missing _CST) since I thus only have C1
and it should thus be set to C1.
What would be interesting is this output *before* any suspend, not after ;)
Oh, and your temperature after boot goes backwards since booting is a very
active period, obviously.
