Hi!
I've updated to vanilla 2.6.19 on my Pentium-D (dual-core x86_64) box.
Now I can't see even C1 in the /proc/acpi/processor/*/power output:
[EMAIL PROTECTED]:~$ cat /proc/acpi/processor/CPU1/power
active state: C0
max_cstate: C8
bus master activity: 00000000
maximum allowed latency: 2000 usec
states:
[EMAIL PROTECTED]:~$ cat /proc/acpi/processor/CPU2/power
active state: C0
max_cstate: C8
bus master activity: 00000000
maximum allowed latency: 2000 usec
states:
Another interesting thing is shown here:
[EMAIL PROTECTED]:~$ cat /proc/acpi/processor/CPU1/info
processor id: 0
acpi id: 1
bus mastering control: no
power management: no
throttling control: yes
limit interface: yes
[EMAIL PROTECTED]:~$ cat /proc/acpi/processor/CPU2/info
processor id: 1
acpi id: 2
bus mastering control: no
power management: no
throttling control: no
limit interface: no
As I remember, both cores were showing the same things formerly.
The only line referring to CPUs during boot is
ACPI: Processor [CPU1] (supports 8 throttling states)
and CPU2 is not mentioned at all.
The last (but maybe not acpi-related) strange thing is that in /proc/cpuinfo,
CPU1 reports 6403.56 bogomips (as always, approximately twice the clock) and
CPU2
8314.32 ones (too much). It's also very suspicious. Formerly the difference was
very small.
Should I provide more info to debug these things, or is it OK ?
With regards, Pavel Troller
