Bug#421879: cpufreq_ondemand: cpufreq_ondemand responds too slowly
Greg Kochanski
Version: 2.6.20-3
Severity: minor
File: cpufreq_ondemand
Cpufreq_ondemand takes too long to respond to a load increase.
Currently, one cannot set /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate_min
to anything smaller than 500000 (0.5 second). Currently, the default is 1.0 second.
That's not good for the default case on my P4 with the 2.6.20 kernel, where
/sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq is 300MHz or so.
In the default case, the CPU is oozing along at 300MHz, and response
is awful if you type a command at a console or drag a window or something.
The ondemand governor responds 1 second later, but by then you've
already been annoyed by the sluggish response.
(Just for comparison, if someone can type at the modest rate of 40 words per minute,
each word takes just 1.5 seconds. For typical linux commands like "ls",
the typing is over in something like 0.3 second.
As another comparison, humans can easily notice 0.1 to 0.2 second long pauses in
speech.) Essentially, if the ondemand governor introduces delays much longer than
0.1 seconds, people will notice hesitations and find the computer to be sluggish.
Suggestions:
1) allow sampling_rate_min to be set to smaller values, like 0.1 second.
The default sampling_rate_min should probably be 0.25 seconds.
If that were the case, the CPU would power up before
a window drag (or similar motion) was finished, and the response would
probably seem acceptably snappy.
2) Make the default scaling_min_freq be somewhat larger, perhaps 670 MHz or
20% of the max clock speed. This will (of course) reduce laptop life,
but I suspect that it won't make a noticeable change.

actually the sampling rate is dependent on the transition latency for

you can already do that by setting /etc/default/cpufrequtils from the
cpufrequtils package.

Yes, you can. However, I was arguing for a change in the defaults,
so that the average user would get a better performance with the
default settings.

assume your processor takes 100ms to switch from one frequency to
another. Ondemand takes this value as a base to calculate the polling
frequency (min, max et al.) and to avoid the possibility to clog the
system with to many transitions it sets a lower value that is a multiple
of the transition latency.

this bug then belongs to the package that sets ondemand as default
governor, which isn't the kernel.

OK. So, if I can find an actual specification for the transition
latency, you could replace the assumed value with the real one.
Right?
I'd also suggest changing (in cpufreq_ondemand.c )
#define MIN_SAMPLING_RATE (def_sampling_rate / 2)
to
#define MIN_SAMPLING_RATE (def_sampling_rate / 10)
The current MIN_SAMPLING_RATE enforces a fairly conservative,
slow sampling rate. By lowering the limit, you could allow people to
experiment and tune their systems, and see if a more rapid sampling
rate would actually improve things or not.
(Note that this would not change the default behavior at all!)
Even with this more agressive limit, the CPU would still (at worst)
only be spending 1% of its time in the middle of a transition between
one speed and another. It's easy to imagine that some people would
trade off a 1% overhead for more rapid response to a mouse motion.
Anyhow, there are good human interface reasons to try to get the
sampling rate down to 100ms, if it can be done without affecting
overall performance significantly. Reducing the MIN_SAMPLING_RATE
allows people to experiment easily, so it ought to be a good idea.
Greg Kochanski
perhaps. Or, maybe if you have ACPI turned on properly, perhaps
the kernel can read the latency from the processor itself.
Anyhow, he says that the latency is 10 - 100 microseconds for Intel
processors. Since the values of policy->cpuinfo.transition_latency
in the kernel seem to be much longer than that
(based on http://lists.debian.org/debian-devel/2006/12/msg00184.html ,
e.g. the Pentium 4 is used as if it has a 1000 microsecond latency),
it looks like they ought to be reduced to the correct values.

So, if you have a CPU with latency 100uS, ondemand is already polling at 100 mS (10 times per sec). You may see freq changing lesser number of times than that. But, that will be because thats when CPU load actually changed and not because ondemand is polling once per second. On all Intel systems I have seen ondemand samples atleast 9 times per second.

Yes, it's a bit confusing/confused.
They are talking about P-states, the p4_clockmod deals with throttling
(T-states), not frequency scaling[1].
So I guess they didn't get your question right or you didn't include the
necessary information.
Also, you may want to redirect most of this discussion to the
cpu...@lists.linux.org.uk mailing list (where probably the same
engineer that answered to you is usually hanging out). Sorry for not
mentioning that before.
[1]: Basically throttling the processor just add idle cycles without
saving any power, frequency scaling actually scales voltage and
frequency.
