Temperature Widget

stephenw10

dev.cpu0.temperature is created by coretemp(4).
My box has a Core CPU but the ACPI is broken so I have no thermal zones.

According to intel docs, the Atom D510 has an on-die thermal sensor that can be read.
Looks like BSD or some BIOS issue prevents that from happening, because the

sysctl hw.acpi.thermal

returns zilch. :(
Hence, of course, no reported temperature. No wonder I can't see it ;)

i'm using a atom d510 also, search the forum; there was a write up on how to install coretemp.ko on the system.

Hi,
afaik acpi was invented after those processor specific extensions were developed.
by now its available on most platforms and supports more sensors.
pfSense currently relies on dev.cpu.temperature and uses ACPI.tz0 as a fallback.
but only one sensorvalue of them is shown and this might be wrong.

For this reason i expanded the code in my tree to ask acpi for all the temp sensors.
This will give us more options in the GUI, including to select coretemp when we want.
Ill post a patch when its ready, so everyone can test it.

For 2.0.1 (FreeBSD 8.1 base).
Copy coretemp.ko (32bit or 64bit) into /boot/modules
Add```
coretemp_load="YES"


I thought these were already in 2.1?  :-\ Hence referencing them in the widget.

If motherboard manufacturers bothered to code their ACPI tables correctly there wouldn't be a problem! >:(

…repost...
Hehe, im running on virtualized hardware, so i need to ask my bank to buy a new system which supports the processor specific module ;))
Anyway, both will be supported bythe widget

Steve, are you referring to the FireBox X500?

Recently my FB X500 fan/blower died and I had to open my X500, put a cpu fan in place of the blower and leave the cover off while I wait for new replacements I ordered off of eBay (from HK of course…) and was wondering if there was a way of enabling such widget for a Celeron 1200Mhz

Nope I was talking about the XTM5.
You can use the output of mbmon to drive the dashboard widget. We had a long thread up on this for 2.0.X, I'm sure a lot of it would be relevent here.

ah, informative - ill read that in a minute.

decided to just post what i got till now:
The code defaults to dev.cpu0 [as is] but is able to handle multiple acpi temperatures too if that module is used instead.


function get_temp() {
//  queries thermal sensors via sysctl. 
// returns array of sensors and their corresponding values

        $arr_parsed ="";
        $arr_temp = array();

        $filter_acpi = "tz[0-1].temperature";

     // escaping for possible inclusion in config.xml

        $oid_cpu = escapeshellcmd("dev.cpu0.temperature");
        $oid_acpi = escapeshellcmd("hw.acpi.thermal");

     // First, query for a processor specific sensor on the die
         exec("/sbin/sysctl '". $oid_cpu ."' | grep -E 'cpu.*temperature'" , $arr_cpu);
        // exec ("cat /root/temp_cpu | grep -E 'cpu.0.temperature'" , $arr_cpu);

         if (arr_cpu != "") {
              $arr_temp = array_merge($arr_temp,$arr_cpu);
          }

     // Alternative: query all acpi thermal zones.

           exec ("sysctl ". $oid_temp ." | grep -E '". $filter_acpi ."'" , $arr_acpi);
          // exec ("cat /root/temp_acpi | grep -E '".$filter_acpi."'" , $arr_acpi);

          if (arr_acpi != "") {
              $arr_temp = array_merge($arr_temp,$arr_acpi);
             }

           foreach (($arr_temp) as $value) {
             preg_match("/tz[0-9]|cpu/i", $value, $sens_id); // get sensor id 
             preg_match("/[0-9]{1,2}.[0-9]/", $value, $sens_val);   // get temperature value
             $arr_parsed[] =  array ($sens_id, $sens_val);
           }

           return($arr_parsed);
        }

is nearly finished now but well see. Anyway, its main purpose is to train me some pfSense gui customisation skills, so no problem for me.
Heres what its look like by now:

So where do we get the coretemp.ko that's compatible with pfSense 2.1 short of building a BSD 8.3 kernel?
Is this going to end up in the regular distribution at some point or will this remain in the everyone interested hacks it in on their own territory?

Guest

Oh, its written Source independent (see discussion above) to let the users choose what they want to use.
Edit:
Im currently banned from the highspeed World and have to use gprs till eoM. (:grm:)
ill sync wt current git and do the commit as soon as my highpriced provider is able to…

till then here are the other changed functions:


function updateTemp(obj_json) {
/*  modify the red / grey bar gifs according to the temperature
    ratio is one pixel per degree.
*/

        jQuery.map(obj_json,function(value,index){
        tempmeter = "#tempmeter" + value
        tempwidtha = "#tempwidtha" + value
        tempwidthb = "#tempwidthb" + value
        console.log(tempmeter);

        jQuery(tempwidthb).css('width',(100 - value[1]) + 'px');

        if(jQuery(tempmeter))
                jQuery(tempmeter).html(value[1] + '\u00B0' + 'C');
        if(jQuery(tempwidtha))
                jQuery(tempwidtha).css('width',value[1] + 'px');
        if(jQuery(tempwidthb))
        jQuery(tempwidthb).css('width',(100 - value[1]) + 'px');

});

and in system_information.widget.php


                        Temperature 

                                ![left bar](./themes/<?= $g['theme']; ?>/images/misc/bar_left.gif)![red bar](./themes/<?= $g['theme']; ?>/images/misc/bar_blue.gif)![gray bar](./themes/<?= $g['theme']; ?>/images/misc/bar_gray.gif)![right bar](./themes/<?= $g['theme']; ?>/images/misc/bar_right.gif)

I don't have 2.1 running on anything right now so I can't check but is it not included in the image? If not it just needs copying from a FreeBSD 8.3 install.

Any chance of an option for Deg F ? Large numbers of people just never grokked the metric system sadly. :-\

Guest

Hi, when the code gets accepted in main, then it will be in the image.
sorry, for the first run it will stay with degree ;(

But this patch is just the first of two. A further one, which i plan to be more dynamic and more configurable in the gui will follow.
By now we have migration phase, where the view is generated by a mix of php and js output)
In that second patch i plan to seperate them and use php only for the backend and js for the ~~complete system_information.widget~~
Edit - no lets keep it easy, just for the temps :)

But for now - Ill note down a todo for an Option to switch output between Fahrenheit / Degrees ;)

If you need it faster, you can add code to check for the timezone after the patch has been accepted.

hanD !

Is there any chance to convert this into a package that also installs the coretemp.ko and loads it, because without this won't work on my system, and it being a fanless design, I'd love to know if things go badly in terms of temperature for some reason…

Thanks! :) I "pkg_add -r mbmon" and at least I can run it in command line. So I have 3 different "temps" when I run mbmon…

Temp.= 47.0, 127.0, 79,0; Rot.= 0, 0, 0
Vcore = 1.49, 3.38; Volt. = 3.31, 4.95, 11.67, -3.06, -6.12

If -T3 is the CPU and that's in celcius I think I'm frying my CPU ATM!! But it's been running forever like this...?

EDIT 1:
Ok, T1 is my CPU temp, it went down to 46.0 when I put another fan to help the one I have temporarily. BTW I modified my functions.inc.php and I now have Temp in my GUI :D Thanks again Steve!

EDIT 2:
I changed the -I to -i to show integer (no .0 at the end)

rcfa

mbmon doesn't seem to work here
So I guess I'd need coretemp. Where can we get the required files for that (amd64/BSD 8.3)?

Even if it was 79, that's fine for most modern CPU's. My MacBook Pro runs about 50-60 in normal use and keeps the fan running about 2000 RPM, but doesn't start ramping up the fan speed until just under 80. Under load, it throttles the fan speed up and down to keep the CPU in the 80-90 range.

Guest

Depends on if its fahrenheit or celsius too, hehe.

I see that mbmon is getting much attention and currently we support coretemp and acpi.
The code generates a source indepent temperature array, so its possible to add mbmon to.
I will add it as a source. Its not much effort and then everyone is able to to query with his favorite toy in the BE ;)

–-

Maybe ill decide do a package too in the future, when i build up enough knowledge to do so, but lets keep the balls down for the moment :)
After all atm its just a neat patch which adds some sensors.

Steven posted a link to the coretemp modules here: http://files.pfsense.org/jimp/ko-8.1/amd64/coretemp.ko
