Hi all,

I admit to = using beta software, and to the possibility that the issue is not in lm-sen= sors, but since I'm very interested in getting my issue fixed, I think this= list is the right place to start at least.

I upgraded = to Ubuntu 10.10 beta today, and the almost immediate result is that the fan= has become noisy as hell.

I have a De= ll XPS Studio 17 laptop, bought earlier this year. It has (among other thin= gs) an i7 Q820 processor.

I never ran= sensors before the upgrade (didn't have any fan issues there), so I don't = know if there's any actual differences in the output, but here goes.

Just runnin= g sensors give me:

acpitz-virt= ual-0

Adapter: Vi= rtual device

temp1: = +26.8=C2=B0C (crit =3D +127.0=C2=B0C)

temp2: = +61.0=C2=B0C (crit =3D +85.0=C2=B0C)

Since I've = little or no load on the CPU, I find the latter value unlikely high (but it= seems to be dropping now so I'll guess I will see how it evolves). Anyway,= I ran sensors-detect, and it found next to nothing apparently. I then down= loaded the svn version, ran it, and it came to a different conclusion (does= n't Ubuntu beta 10.10 have a recent lm-sensors?):

I could/sho= uld install the coretemp module, and so I did. Now sensors gives me:

acpitz-virt= ual-0

Adapter: Vi= rtual device

temp1: = +26.8=C2=B0C (crit =3D +127.0=C2=B0C)

temp2: = +57.0=C2=B0C (crit =3D +85.0=C2=B0C)

coretemp-is= a-0000

Adapter: IS= A adapter

Core 0: = +57.0=C2=B0C (high =3D +84.0=C2=B0C, crit =3D +100.0=C2=B0C)

coretemp-is= a-0001

Adapter: IS= A adapter

Core 1: = +57.0=C2=B0C (high =3D +84.0=C2=B0C, crit =3D +100.0=C2=B0C)

coretemp-is= a-0002

Adapter: IS= A adapter

Core 2: = +58.0=C2=B0C (high =3D +84.0=C2=B0C, crit =3D +100.0=C2=B0C)

coretemp-is= a-0003

Adapter: IS= A adapter

Core 3: = +57.0=C2=B0C (high =3D +84.0=C2=B0C, crit =3D +100.0=C2=B0C)

No fan spee= ds though, and I'd expected such info from a laptop this expensive. Looking= at sensors-detect again, I have this:

Probing for= Super-I/O at 0x4e/0x4f

Trying fami= ly `National Semiconductor'... Yes

Found unkno= wn chip with ID 0x8512

Is this som= ething of interest?

As a side n= ote, the fan turned itself down a notch now, but it is still more noisy tha= n I'd expect it (I think).

Anyway, if = anyone would like to help me with suggestions or similar as to what to look= for/what to test, it would be much appreciated. If there is something I ca= n do to help the lm-sensors project in this regard, I'll do my best.

Best regard= s,

Lars Ivar I= gesund

Different vendors use different "access keys" to the LPC configuration space. These are sequences of bytes to be written to the register port. National Semiconductor is (was) the only vendor without an access key, that is, you can access the configuration space at any time. For this reason, we try to detect National Semiconductor devices first. Nuvoton indeed has one chip in this family (WPCD377I) because this device is an older National Semiconductor device they inherited when buying part of National Semiconductor's business a few years ago. So the mysterious chip could indeed be a Nuvoton-labelled chip, but be a National Semiconductor design. Either way, most LPC chips on laptops are minimalist and don't include hardware monitoring features, so there's probably little interest in investigating this. The only way to move forward would be to find a detailed listing of this laptop's parts (very hard to get usually) or to open the laptop's case and have a visual look (usually not easy either.) As in most laptop cases, the problem and solution are more likely related to laptop-specific code or ACPI. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jean Delvare Date: Sat, 11 Sep 2010 09:03:31 +0000 Subject: Re: [lm-sensors] Lack of fan sensor output after Ubuntu upgrade Message-Id: <20100911110331.695f3fa4@hyperion.delvare> List-Id: References: <201009101529.26294.larsivar@igesund.net> In-Reply-To: <201009101529.26294.larsivar@igesund.net> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lm-sensors@vger.kernel.org On Sat, 11 Sep 2010 10:53:39 +0200, Jean Delvare wrote: > On Fri, 10 Sep 2010 09:15:27 -0700, Guenter Roeck wrote: > > On Fri, Sep 10, 2010 at 09:29:25AM -0400, Lars Ivar Igesund wrote: > > > Probing for Super-I/O at 0x4e/0x4f > > > > > > Trying family `National Semiconductor'...

Once we're sure we can identify the chip reliably, support should be added to sensors-detect. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors From mboxrd@z Thu Jan 1 00:00:00 1970 From: Guenter Roeck Date: Mon, 13 Sep 2010 14:17:16 +0000 Subject: Re: [lm-sensors] Lack of fan sensor output after Ubuntu upgrade Message-Id: <20100913141716.GD359@ericsson.com> List-Id: References: <201009101529.26294.larsivar@igesund.net> In-Reply-To: <201009101529.26294.larsivar@igesund.net> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lm-sensors@vger.kernel.org On Mon, Sep 13, 2010 at 04:05:45AM -0400, Jean Delvare wrote: > On Sun, 12 Sep 2010 12:32:13 -0700, Guenter Roeck wrote: > > On Sat, Sep 11, 2010 at 05:03:31AM -0400, Jean Delvare wrote: > > > BTW...

The datasheet is at http://www.docin.com/p-4432074.html. The site is in Chinese (?), and the datasheet is not in pdf but displayed with flash, so it is a bit cumbersome to read. Chip ID is 0x8512 (registers 0x20 and 0x21), and chip version is 0x22 (register 0x22). Not sure if the version is correct, as it matches the register address, but that is what it says. I agree, it would make sense to add it to sensors-detect. I looked through the code, but wasn't entirely sure how to do that, since the NS chip IDs are all 8 bit. Can I just add an entry for chip ID 0x8512 ? Also, I don't know what to specify as logdev, since the sensors are all accessed through an embedded 8032 controller.

That's more of an issue. The point of listing a logical device is that logical devices can be disabled, so it's a convenient way to figure out whether the monitoring feature is used on a given system. If the "embedded 8032 controller" corresponds to one logical device then that's the one to test. If not, we may have to write custom code for this device. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors From mboxrd@z Thu Jan 1 00:00:00 1970 From: Guenter Roeck Date: Mon, 13 Sep 2010 16:13:49 +0000 Subject: Re: [lm-sensors] Lack of fan sensor output after Ubuntu upgrade Message-Id: <20100913161349.GB593@ericsson.com> List-Id: References: <201009101529.26294.larsivar@igesund.net> In-Reply-To: <201009101529.26294.larsivar@igesund.net> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lm-sensors@vger.kernel.org On Mon, Sep 13, 2010 at 10:43:57AM -0400, Jean Delvare wrote: > Hi Guenter, > > On Mon, 13 Sep 2010 07:17:16 -0700, Guenter Roeck wrote: > > On Mon, Sep 13, 2010 at 04:05:45AM -0400, Jean Delvare wrote: > > > On Sun, 12 Sep 2010 12:32:13 -0700, Guenter Roeck wrote: > > > > On Sat, Sep 11, 2010 at 05:03:31AM -0400, Jean Delvare wrote: > > > > > BTW...

However, if those LDAs are active, it does not mean that ADCs or fan control is active. The datasheet does not specify details of ADC and fan control communication between host and 8031; that seems to be microcode specific. Also, it looks like the 8031 code is system specific and not provided by the chip vendor. So it might not even be possible to obtain ADC and fan control status. Or, of course, I might simply be missing something. For sensors-detect, we could possibly tag ADC and fan control support to LDA 11h and/or 12h. Would that make sense ?

Would that make sense ? If there's hope to ever write a driver for this, yes it makes sense. If not, we're probably better off just claiming that the device has no monitoring features. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors From mboxrd@z Thu Jan 1 00:00:00 1970 From: Guenter Roeck Date: Mon, 13 Sep 2010 17:24:32 +0000 Subject: Re: [lm-sensors] Lack of fan sensor output after Ubuntu upgrade Message-Id: <20100913172432.GC1092@ericsson.com> List-Id: References: <201009101529.26294.larsivar@igesund.net> In-Reply-To: <201009101529.26294.larsivar@igesund.net> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lm-sensors@vger.kernel.org On Mon, Sep 13, 2010 at 01:02:06PM -0400, Jean Delvare wrote: > On Mon, 13 Sep 2010 09:13:49 -0700, Guenter Roeck wrote: > > It looks like data is passed between 8031 and host using LDA 11h and/or 12h > > (power management).

I'll update sensors-detect to reflect this.

There are a couple of proposed patches, but I don't know if anything has been integrated into the kernel. The discussion is still ongoing.
