[gentoo-user] Core i7 M620 power management problem

[-- Attachment #1: Type: text/plain, Size: 1790 bytes --]

I have a nagging problem that is driving me batty.

I have a Dell Precision M4500:
Linux m4500 2.6.36-gentoo-r6 #1 SMP Wed Dec 29 07:57:47 PST 2010 x86_64
Intel(R) Core(TM) i7 CPU M 620 @ 2.67GHz GenuineIntel GNU/Linux
model name      : Intel(R) Core(TM) i7 CPU       M 620  @ 2.67GHz
and it even has these fancy capabilities:
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca
cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx

xtpr pdcm sse4_1 sse4_2 popcnt aes lahf_lm ida arat dts tpr_shadow vnmi
flexpriority ept vpid

however, I cannot get the thing to change speeds. It is adamantly stuck at
its pokey molasses slow 1.2GHz:

blongman@m4500 /sys/devices/system/cpu/cpu0/cpufreq $ cat scaling_*
2667000 2666000 2533000 2399000 2266000 2133000 1999000 1866000 1733000

conservative ondemand userspace powersave performance
1199000
acpi-cpufreq
performance
1199000
1199000
<unsupported>

A strangeness I have noted is that /proc/cpuinfo has this for its power
capabilities:
power management:
Nothing.

I don't recall what it was on the other i7, but my AMDs have this sort of
thing:
power management: ts ttp tm stc 100mhzsteps hwpstate

Why this is driving me batty is that I just this summer set up a similar
M4500, but with a fancier i7 in it, *specifically* to enable and manage its
power capabilities and I was completely successful. If I swap my disk and
boot Windows 7, it behaves like a champ, so I don't think it's a BIOS issue.
What else could I look at since I've been through all versions of kernels
from 2.6.32 to today's 2.6.36?

FWIW I have Core i7 920, and it also has nothing in the power
management in cpuinfo, but CPU frequency scaling does work and speeds
change (using ondemand governor, in a desktop machine).

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_*
2661000 2660000 2527000 2394000 2261000 2128000 1995000 1862000 1729000 1596000

So it seems similar to yours except that your max_freq and min_freq
are the same! Which matches what you say about it never going faster
than the minimum speed.

In kernel docs Documentation/cpu-freq/cpu-drivers.txt there is some
information about how the min and max speed are set by the policy that
is in use (by whatever driver is controlling the scaling). So I don't
know if there is a userspace program (like KDE laptop stuff) that
might be overriding with its own faulty settings?

Seems like your kernel settings are probably okay since you can see
all of that so far. If you run powertop can it see all of the C-states
and P-states without any problems?

I see it but I don't have a solution.

Maybe some strange limitation within the BIOS of the motherboard?
Ah, you wrote that Win does fine ... so ...

Do you have the correct CPU chosen in your kernel-config?

Maybe someone with a core i7 could help out here better than me ...

Here's an interesting item:

12:41:00# cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit
1199000

which sort of jives with the "asserted by call to hardware" in the
cpufreq-info section:
analyzing CPU 3:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0 1 2 3
  CPUs which need to have their frequency coordinated by software: 3
  maximum transition latency: 10.0 us.
  hardware limits: 1.20 GHz - 2.67 GHz
  available frequency steps: 2.67 GHz, 2.67 GHz, 2.53 GHz, 2.40 GHz, 2.27
GHz, 2.13 GHz, 2.00 GHz, 1.87 GHz, 1.73 GHz, 1.60 GHz, 1.47 GHz, 1.33 GHz,
1.20 GHz
  available cpufreq governors: conservative, ondemand, userspace, powersave,
performance
  current policy: frequency should be within 1.20 GHz and 1.20 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency is 1.20 GHz (asserted by call to hardware).
  cpufreq stats: 2.67 GHz:0.25%, 2.67 GHz:0.01%, 2.53 GHz:0.01%, 2.40
GHz:0.01%, 2.27 GHz:0.01%, 2.13 GHz:0.01%, 2.00 GHz:0.01%, 1.87 GHz:0.01%,
1.73 GHz:0.01%, 1.60 GHz:0.01%, 1.47 GHz:0.01%, 1.33 GHz:0.01%, 1.20
GHz:99.61%  (28)

So, why are there micro-spikes of higher frequencies in the above stats? The
stats section says there are only five transitions.

I ran cpufreq-info on my i7 920, and everything looked normal for mine
compared to yours. And I have tens of thousands of transitions on each
CPU (currently at 8 days uptime)

Can you use cpufreq-set to change the max limit or lock it to a higher
speed? If it works, that's a good sign... if it gets changed back
maybe some userspace powersaving program is messing with it. Like
gnome/KDE or something. If you boot to console and don't start X, does
this problem still happen? I wonder if it happens in X maybe the few
times at greater speeds happened before X loaded. Just a WAG. :)

For example, on my laptop (not an i7, but an old Athlon from 2004),
the KDE laptop powersaving stuff does not work properly, it either
locks me at slowest speed, or highest speed, or... but I think in my
case it's related to the corrupt DSDT, crappy BIOS and complete
inability for it to read the battery state most of the time... It
doesn't know if it's plugged in or on battery, or how much battery
life is left, or it thinks 84% remains and that number never changes
(until laptop suddenly dies without warning). Of course all of that
works perfectly fine in Windows on the same machine...

In my kernel config on my i7, in the cpufreq sections I have this:

#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=y
# CONFIG_CPU_FREQ_DEBUG is not set
CONFIG_CPU_FREQ_STAT=y

I can send you my entire .config if you want to compare.

Yes, mine is quite similar:

# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=y
CONFIG_CPU_FREQ_DEBUG=y
CONFIG_CPU_FREQ_STAT=y
CONFIG_CPU_FREQ_STAT_DETAILS=y
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=y
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=y
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y

#
# CPUFreq processor drivers
#
# CONFIG_X86_PCC_CPUFREQ is not set
CONFIG_X86_ACPI_CPUFREQ=y
# CONFIG_X86_POWERNOW_K8 is not set
# CONFIG_X86_SPEEDSTEP_CENTRINO is not set
# CONFIG_X86_P4_CLOCKMOD is not set

#
# shared options
#
# CONFIG_X86_SPEEDSTEP_LIB is not set
CONFIG_CPU_IDLE=y
CONFIG_CPU_IDLE_GOV_LADDER=y
CONFIG_CPU_IDLE_GOV_MENU=y
CONFIG_INTEL_IDLE=y

I do run KDE but it is independent of KDE. I don't run kdm by default, just
the console, and it is still the same. In fact, the KDE power stuff is not
even around. Could that mean it's just a USE flag issue? It doesn't seem it
because I have acpi and udev.

Did you try changing the default to CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND ?

Yes, Mick, that was my first governor. I thought I'd try to see if it
would behave at top speed if I set it to "performance". No luck, though.
And I can easily change the governor. It swaps out to any of the
installed governors with aplomb, although I have to do this manually. I
can't change governors from gkrellm, for instance. If I change it
manually, the new governor shows up there, but it's read-only so to speak.

I don't know if the idle controller has anything to do with this but
here is what my idle controller looks like:

/sys/devices/system/cpu/cpuidle
08:43:14# ls -l;cat current_*
total 0
-r--r--r-- 1 root root 4096 Dec 30 08:43 current_driver

Is there a plugin for gkrellm that does governors?  Can't find it on mine.

Yes, the CPUfreq plugin is in x11-plugins/gkrellm-cpufreq

Just a wild guess:  are you running some desktop applet that manages the cpu 
frequency and is stuck on manual with a low setting?

I have the i7 Q 720 @ 1.60GHz, which is supposedly go up to 2.8G with turbo 
boost, but can't say that I have ever seen it going that high ... not sure if 
there's a setting somewhere I should tweak.  This is from cpuinfo:

=========================

power management:

As you can see power management is also blank.

These are my frequencies:

PS.  Any ideas what makes that turbo thingy kick in?

The only thing that runs at boot is cpufrequtils and here is the config for
it:

# Options when starting cpufreq (given to the `cpufreq-set` program)
START_OPTS="--governor performance"

# Options when stopping cpufreq (given to the `cpufreq-set` program)
STOP_OPTS="--governor performance"

# Extra settings to write to sysfs cpufreq values.
#SYSFS_EXTRA="ondemand/ignore_nice_load=1 ondemand/up_threshold=70"
SYSFS_EXTRA="ondemand/ignore_nice_load=1"

And since I have power mgmt debug turned on, all my logs are belong to pm:
e1000e 0000:00:19.0: __pm_runtime_resume()!
e1000e 0000:00:19.0: __pm_runtime_resume() returns 1!
scsi host1: __pm_runtime_resume()!
scsi host1: __pm_runtime_resume() returns 1!
scsi host1: __pm_runtime_resume()!
scsi host1: __pm_runtime_resume() returns 1!
scsi host1: __pm_runtime_resume()!
scsi host1: __pm_runtime_resume() returns 1!
scsi host1: __pm_runtime_resume()!
etc, etc, etc, ad nauseum....

And even when I try this kind of thing:
/sys/devices/system/cpu
19:08:23# for a in cpu?/cpufreq/scaling_max_freq; do   echo -n 2667000 > $a;
done
/sys/devices/system/cpu
19:09:05# cat cpu?/cpufreq/scaling_max_freq
1199000
1199000
1199000
1199000
/sys/devices/system/cpu
19:09:20# for a in cpu?/cpufreq/scaling_governor; do   echo -n performance >
$a; done

I can see gkrellm get its governor changed but I cannot override the max
freq. How can I tell what the BIOS is reporting?  Here is what dmidecode
tells me about the CPU:

I do not have cpufreutils installed, but use the ondemand governor as a 
default.

This is what my i7 Q is showing:

My turbo reading leads me to think that the dmidecode is not necessarily

I've always laughed at the shoddy workmanship of DMI. I don't know the
percentage of boards with "To Be Filled By O.E.M." in them, but most of
it is useful information. Here's another snapshot of idle stats, so it
looks like it's handling the idle routines okay:
/sys/devices/system/cpu/cpu0/cpuidle
09:05:05# for a in {0..3}; do   echo === state$a ===;   ls state$a;cat
state$a/*; done
=== state0 ===
desc  latency  name  power  time  usage
CPUIDLE CORE POLL IDLE
0
C0
4294967295
24712609
9234
=== state1 ===
desc  latency  name  power  time  usage
MWAIT 0x00
3
NHM-C1
4294967294
530943161
2079744
=== state2 ===
desc  latency  name  power  time  usage
MWAIT 0x10
20
NHM-C3
4294967293
4419507305
4950330
=== state3 ===
desc  latency  name  power  time  usage
MWAIT 0x20
200
NHM-C6
4294967292
49546556808
7879505

It still points to that "max cpu freq" as the culprit.

I don't recall what kicks in the turbo mode on the i7's. I thought it
was simply bumping the speed of one core if it could keep the other
core(s) in the deep sleep state. So, a single threaded process would get
a speed improvement. If your other cores were running you'd be out of
luck. Could be wrong. Brain's been running about half a century now, so
it's wearing out.

Bill, just for a check, does it scale correctly if you boot from a live-cd?

Well, if I change the BIOS to turn off SpeedStep, it goes to 2.67
GHz.....works great!

LOL! Well, if by "solved" you mean that I am able to use the full power
of my CPU, then, yes, it is solved. However, it is now completely
incapable of having its CPU controlled for power, so once I go on
batteries, I have about an hour and a half....so in that sense, no, it's
not solved. No, it's not solved. I am going to burn an ISO and boot one
of those "other" distros that shall remain nameless and see if there is
something strange with my Gentoo kernel madness or whether it's this
machine.

Hmm ... could it be a buggy BIOS?  Are you running the latest firmware for it?

Have you diff'ed the LiveCD kernel and yours?

Yes, that would also have been my next question.
Maybe you even *find* a bug in that BIOS right now that should be corrected.

I actually am running the latest firmware. I had thought that maybe that was
the problem, but I rev'ed it about a month ago and it did not solve it. Am
waiting for the Ubuntu 10.10 to finish downloading and give that a whirl.

Did you diff the kernel configs to see what's different between the two OS'?

There was no /proc/config.gz. How do you find it without that? I looked
through the proc tree but didn't find anything.

I added some printk's to the kernel and I see some segfaults. I'll try
another kernel tomorrow and see if tuxonice gives me anything different.

I'm sure that Ubuntu includes the current kernel(s) config in /boot/.  Look 
for something like /boot/config-2.6.XX-generic or -server or -386 depending on 
your arch and kernel you have chosen.  I believe a typical desktop 
installation runs *-generic.

Here are some powertop results I see when compiling world:

     PowerTOP version 1.13      (C) 2007 Intel Corporation

Cn                Avg residency       P-states (frequencies)
C0 (cpu running)        (100.0%)      Turbo Mode     0.0%
polling           0.0ms ( 0.0%)         2.67 Ghz     0.0%
C1 mwait          0.0ms ( 0.0%)         2.54 Ghz     0.0%
C2 mwait          0.0ms ( 0.0%)         2.40 Ghz     0.0%
C3 mwait          0.0ms ( 0.0%)         1199 Mhz   100.0%

So it seems like all the CPU Power state is fine internally to the CPU but,
it's just that it cannot go to the higher speeds for some reason.
