but if the set is empty, you don't get any data, and the "emulation" side of powertop
is likely a better choice... since there are C states, just not counters.

Hi,

not sure if this is an important information or not, but I am getting 
the "138% idle" behaviour for all of the systems where reading out the 
current CPU frequencies via PowerTop is not possible.

Best regards
Valentin

looks like powertop checks C6 state `get_msr(number, MSR_PKG_C6_RESIDENCY)' in start
and end measurement for any intel cpu, along with `get_msr(first_cpu, MSR_TSC)'. anyway,
need to investigate. the output that Valentin sees is rather strange, saying that cpu0
is 138% Idle.

	          CPU 0
	Idle      138%

	          CPU 2
	Idle      111,7%

	          CPU 1
	Idle      111,7%

	          CPU 3
	Idle      111,7%

not sure that powertop performs any specific MSRs at all, since most of MSRs are
called correspondingly to c-state flags (has_cXXX), e.g.

__init:
	if (model == 0x45 || model ==0x3D)
		has_c8c9c10_res = 1;



and later:

	if (has_c8c9c10_res) {
		c8_before    = get_msr(number, MSR_PKG_C8_RESIDENCY);
		c9_before    = get_msr(number, MSR_PKG_C9_RESIDENCY);
		c10_before    = get_msr(number, MSR_PKG_C10_RESIDENCY);
	}

	and so on.

so turns out the L5410 is one generation prior to NHM, and does not support some of the internal MSRs we're using.
I'll talk to Alexandra (pending vacations, it's that season) to see what we can do

thanks! ok, so cpu model 0x17 is not listed as a supported one in
src/cpu/intel_cpus.cpp:intel_cpu_models[] to begin with, and no
C-states are initialized as a result. Let's wait for Intel devs
to add cpu/core/package models and corresponding C-states.

Alexandra, will you take care of this?

hm... a *wild* guess. can you check what cpu model is getting passed to
nhm_core::nhm_core(int model)? the problem might be (or might be not) that we
don't set any of C-state flags. if none of C-states set, then no MSR work is
getting done, and hence nothing is reported back. (yeah... we could check
documentation, search the web, etc. but let's do it the lazy way).

Re: [Powertop] Does PowerTop support MHz numbers for Intel Xeon L5410 CPUs ?

Hi,

as you already guessed Debian still uses a 2.0 version.
However, I git cloned 2.6.1 and the "head" versions from GitHub, built 
them both and tried them - still the same result.

Is it known if this particular CPU model does not support reading out 
the CPU frequency values or could this be another problem?

Best regards
Valentin

Hello,
am not really familiar with debian versioning, but if "2.0" means
upstream release v2.0, then you use a really-really outdated powertop
(several years). in that case I'd recommend to switch to recent version
(2.6 IIRC).

[Powertop] Does PowerTop support MHz numbers for Intel Xeon L5410 CPUs ?

[Valentin Hoebel]

[-- Attachment #1: Type: text/plain, Size: 1040 bytes --]

Hello,

I have been using PowerTop for some time now and would like to thank all 
contributors for their work, especially Intel!

However, when using PowerTop on Debian 7 (Kernel 3.2, PowerTop package 
2.0-0.3) and navigating to "Frequency stats", it does not show the MHz 
numbers. Instead, it shows me the following:

           CPU 0
Idle      138%

           CPU 2
Idle      111,7%

           CPU 1
Idle      111,7%

           CPU 3
Idle      111,7%

Is the CPU model Intel Xeon L5410 simply not supported or is there no 
way to read out the frequencies?

Browsing the source code, I did not stumple accross this CPU model.

Thanks in advance.

Best regards
Valentin
