[Bug 432706] Re: cannot change governor from command line

2012-04-17 Thread Dert Hunter
Doki (lkishalmi) solution works great for me. I`m impressed that i had
to correct it on ubuntu 10.10 maybe on next release it comes fixed. I
had to install cpufrequtils for the cpufreq indicator to work. Is not
very fast but for an old celeron M notebook working as a router ondemand
governator works very well.

FactTech, I don't think there will be any SRU updates for karmic.  I
tried with the lucid kernel and FWIW, the change from the command line
works fine even though it takes quite a while to do so.

2010-11-03 Thread yossarian holmberg
throwing my two cents in; i agree 100% with #23 (dan k.) -- the CPU
frequency scaling control capability and applet is one of my favorite
things about linux and the ubuntu/GNOME desktop environment, and i
attempt to enable it on every single machine i put ubuntu onto.   i have
personally witnessed the big difference it can make on some desktop
systems i've deployed, in terms of how hot they run, and how much power
they use, especially when online 24/7..

have the applet default to 'performance' mode if 'ondemand' is too slow,
sure, but don't break 'ondemand' on purpose!  do you really think the
majority of your userbase is too ignorant to do two mouse clicks to
change the setting themselves? and if so, why do you even still list
'ondemand' as a choice, if you're just going to leave it broken?  the
ubuntu desktop installation doesn't even put the CPU frequency scaling
applet onto the panel by default, you have to put it there yourself.
doesn't it stand to reason that if you put it there yourself, you could
probably also figure out which of the automatic governor settings you're
OK with using?

i would definitely appreciate having that choice back, and i can see
there are still more people on forums asking about this.  to the people
who complain ondemand is too slow: put it in performance mode, leave it
there, and be happy you have a choice about the matter, because right
now some of us have lost our ability to choose to do otherwise, which
isn't right.

final point: are we trying to be more environmentally friendly, or not?
anything that reduces excess heat and power usage is good, in my
opinion.  ;-)

2010-10-27 Thread Dan Kortschak
A binary hack is a silly way to have to fix something that should not
have been broken.

If ondemand is too slow - make the default performance so the user can
choose, rather than making ondemand work exactly the same way as
performance. Honestly, what is the point of having two policies that do
exactly the same thing and remove functionality that is obviously missed
by users?

When will this regression be fixed?

[Bug 432706] Re: cannot change governor from command line

2010-08-06 Thread Doki
Well you don't really need to recompile the module a simple binary hack
could solve the problem. The basic idea is that 1001 is 00989681 in
hex and stored in p4-clockmod.ko as 81969800 a "simple" search for it
and replace it with 80969800. So I did the following hack (far from
being optimal):

1. cp 
/lib/modules/2.6.32-24-generic/kernel/arch/x86/kernel/cpu/cpufreq/p4-clockmod.ko
 p4-clockmod.ko.orig
2. xxd p4-clockmod.ko.orig p4-clockmod.ko.hex
3. vim p4-clockmod.ko.hex (search for 81 and check that it is followed by 96 98 
00 in hexdump)
4. Replace the right 81 to 80
5. xdd -r p4-clockmod.ko.hex p4-clockmod.ko
6. sudo cp p4-clockmod.ko 
/lib/modules/2.6.32-24-generic/kernel/arch/x86/kernel/cpu/cpufreq/p4-clockmod.ko
7. sudo reboot

2010-06-22 Thread FactTech
I'm seeing the same issue with the same apparent cause as Anno Loki
explains in comment #9. Like her, I disagree with this change; I'm
running Lucid on a Sony Vaio PCG-GRZ610 which is a tremendous power hog
when the "ondemand" setting is not available. I had it running for years
using ondemand under Hardy, and I don't understand why this
functionality would be deliberately broken; this seems like a regression
in Lucid, from my viewpoint.

Anno Loki, are you still out there? Any chance you can provide step-by-
steps to modify and recompile the p4_clockmod module? I've never
compiled a module before and would appreciate the guidance (as I'm sure
many other users would).

[Bug 432706] Re: cannot change governor from command line

2010-06-04 Thread Bassjunkie
I believe I am also experiencing the same bug.
I started trying to get CPU scaling enabled on my HP DL380 G3 (2x Xeon 2.4Ghz 
HT) a couple of days back and wasn't having much luck using powernowd or the 
command line to manually set governer.

I ended up using cpufreqd as this at least seemed to allow scaling on
one of the 2 CPU in the machine. I went back in and checked my dmesg and
I'm getting the ondemand governor failed, too long transition latency of
HW, fallback to performance governor error messages (mentioning both
ondemand and conservative).

I'm using the p4-clockmod module for this and the output of cat
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency is also
1001 as mentioned by Anno previously.

[Bug 432706] Re: cannot change governor from command line

2010-02-16 Thread Anno Loki
FYI (I'm not sure how relevant this still is) but 4294967295 is as
recognisable a number as 1001 is: it's -1 on a 32bit processor, or
0x.

The 1001 number in the kernel mod I use is assigned by
   policy->cpuinfo.transition_latency = 1001;

A grep for other modules setting this:
   grep  'policy->cpuinfo.transition_latency' 
/usr/src/linux/arch/x86/kernel/cpu/cpufreq/*.c
reveals a bunch of modules, for the different CPUs, that set:
   policy->cpuinfo.transition_latency = CPUFREQ_ETERNAL;

CPUFREQ_ETERNAL can be found by:
   grep CPUFREQ_ETERNAL /usr/src/linux/include/* -R
   /usr/src/linux/include/linux/cpufreq.h:#define CPUFREQ_ETERNAL  (-1)

So that is indeed the figure. To reenable kernel ondemand/conservative
support for your proc, simply edit the module source for your cpu,
search for transition_latency = CPUFREQ_ETERNAL and replace it with
1000. Note of course that I have a different cpu, so you should
consider such an action as 'experiemental'; if the ondemand/conservative
gov switches too quickly and your proc can't handle it, your system
might run v.slow or stand still, so boot up with the
performance/userspace gov and switch over to test, rather than set
ondemand/conservative as the default on-boot governor.

This is of course just an FYI if you have the problem resolved another
way; I just found the replies as I just updated my kernel and couldn't
remember which file I edited first time round, so came back here to find
my own post :-)

This does indeed work in the Lucid kernel which as I was told runs
straight in karmic without recompilation.  Setting to fix released.  If
somebody figures out what it was exactly that fixed this and provides a
minimal patch I guess that could be backported to the 2.6.31 kernel for
inclusion in karmic.

next steps:
1) bisect to the upstream kernel that broke as well as the one that fixed this
2) recompile Lucid kernel to see if it's fixed there

[Bug 432706] Re: cannot change governor from command line

2009-11-21 Thread Anno Loki
This has been deliverately broken in recent kernel as it's been deemed
"too slow" for us to carry on using. If like me you disagree, you can
reverse the change quite easily if you're building your own
kernel/modules, I'll try and post these details to where I can find
people who've hit the same problem and want to undo the change.

If you run:
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency 
you will notice the latency is 1001, which I thought looked highly 
suspicously like someone had hardcoded that number somewhere to be 1 more than 
a max number set somewhere where the ondemand/etc would work. You can find it 
in the file (assuming kernel sources are in /usr/src/linux) :

/usr/src/linux/arch/x86/kernel/cpu/cpufreq/p4-clockmod.c

If you search in that file for the number 1001 in that file,
decrease it by one to 1000, and recompile the module (if you have
p4-clockmod compiled as a module; if it's linked into the kernel you'll
need to recompile the kernel and reboot).

I have found that changing the up_threshold of the ondemand governor from its 
default to 40 makes it ramp its speed up when I need it to, and stay there 
until it drops back down again. With my usage pattern it's not making these 
switches very often, so any delays in changing the speed are perfectly 
acceptable -to me-. To do this, simply:
echo 40 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold

Hope there's someone out there this helps. Oh, and of course, yay for
open source! We don't have to someone telling us we can't do something
with our own computer cuz they don't think it's fast enough! :-)

** Package changed: gnome-applets (Ubuntu) => linux (Ubuntu)
