Hi all,

Sorry for delay, I'm quite busy with all the stuff and support for lm-sensors is
quite time consumptive. I hope I will have more time for lm-sensors during sunday.

Lets move the thread to this one.

I have seen the "datasheet" it should be enough to write a simple driver but we
need how to detect the superio in first place.

This should be easy to find out yourself:

you may try:
isadump 0x2e 0x2f

If you see all 0xff then the superio must be unlocked

isadump -k 0x87,0x87 0x2e 0x2f

or try -k 0x55

problem is that if none of standard key is working then best way would to ask them:

1) what is the superio unlocking key
2) what is the CR20 ID and what is CR21 revision. (what bits, what values)
3) what logical device is for hardware monitor, (so you can get the 0x290 base
addr from there)
4) is there any ID register in the 0x295/0x296 space?
5) how big is the 0x295 0x296 iospace? just from 0x290 + 8 bytes?
6) The Ultimate Question Of Life, the Universe and Everything

SO please try to "unlock" the superio first. I would bet that the key -k 0x55
will work but check it out yourself ;)

ruik:/tmp# isadump -k 0x87,0x87 0x2e 0x2f 2
WARNING! Running this program can cause system crashes, data loss and worse!

This example shows the unlocked superio and with listed bank 2,
Which is the serial port. At 0x60 you see the base addres: 3f8
you should see there 0x2 0x90 or 0x2 0x95, so cycle the banks from 0 to 15 This
would answer question 3)

question 2) answer is in 0x20 I have there 88 63  part 88 6 is chip ID rest is
revision

question 5) answer: isadump -f 0x290

0290: ff ff ff ff ff 47 90 ff ff ff ff ff ff ff ff ff

I have there just two bytes. Addtionaly you may check if the region is not
reserved by bios in the cat /proc/ioports

Or you can disassemble the bytecode of DSDT table, which will for sure contain
answer to question number 1)

Check the specs here:
http://perso.orange.fr/pierrelib/pnp/PnP_ISA_Spec_v1.0a.pdf

Or any Winbond superio datasheet.

Hi,

I got the mobo up and running with FC5.

Tried the following command:
isadump 0x295 0x296

Results:

The results seem to be correct systemp is around the 30C as shown in the
results from isadump and checked with the bios. 
I do have my doubts about the cpu temp reported in the isadump it says it's
around 45C but when checking in the bios it shows almost 60C. Could it be
the rebooting that is causing the temp to rise so much?

Is it still necessary to unlock the superio and if so could to explain why?

Regards,
Hans

Thats normal with amd cool 'n quiet processors, Linux puts the
processors in its low powerstate unless you do something which requires
all the horsepower, whereas the BIOS always has the processor in its
highest powerstate, try building a kernel with "make -j 4 bzimage" and
then do the isadump again when the kernel is building, then it should be
around 60 degrees under Linux too.

It looks like its not nescesarry as it works without it.

Hi,

Best would be to ask the for additional docs but lets check what we can find out
on our own:

Perhaps the chip can control the fans too. and set some limits... this would be
the undocumented a2-af fields

Yes it would be good to know for detection.

Proceed

Try this

isadump -k 0x55 0x2e 0x2f

Or this ;)

The unlocked suoperIO looks like this. If you manage to see something like this
then proceed down to check what logical device the chip resides. Just switch do
dumps with

> ruik:/tmp# isadump -k 0x87,0x87 0x2e 0x2f 2

and change the last number from 0 1? to 15

and check the bytes at 60: you should see the 02 90 or 02 95

> question 5) answer: isadump -f 0x290

Please provide this dump too

Thanks, Rudolf

Or you could simply try the version of sensors-detect which comes with
lm_sensors 2.10.1, which would detect automatically which key is needed
to unlock the Super-I/O, and which logical device corresponds to
hardware monitoring.

I wrote this code for a reason...

This is the Fintek vendor ID! So this mysterious Epox chip was
certainly subcontracted to Fintek.

Ran on Jean's advice sensors-detect again and it reported when probing for
superior the following:

Found unknown chip with ID 0x0541

Then did an isadump on 0x4e 0x4f and was shown a lot more 0xff :(
I looked at the driver code for the Fintek F71805F Super-I/O chip which uses
0x87 to as key to unlock.

Well, if we write a driver for this chip, it's always better to get the
address from the Super-I/O configuration address space, rather than
hardcoding an arbitrary address. This lets us detect much more reliably
whether the device is there or not, and also lets us deal with
different addresses without user intervention.

Ok,

I'm kinda new to this superio stuff, so I'm glad you and Rudolf are 
helping out.

Maybe I should make my relation to Hans Edgington clear. As you may know 
I'm a university Computer Science teacher and Hans E. is a student of 
mine. As part of his / her last year every student must work on a 
project for 1 day / week during 5 months. Normally the project 
assignments come from real companies, but when we don't have enough 
assignments the teacher(s) create assignments for these projects. After 
seeing the mail from Age Huisman on this I thought it would be a fun 
project for a student to write a driver for this sensors chip.

At first I thought this driver would be much like the uguru driver, but 
I see now with the superio stuff that it will be somewhat different, 
what would be a good driver to start with as a skeleton to base this 
driver on?

Also are there datasheets of similar (fintek) superio chips available 
somewhere, those could be of great help.

Regards,

Hans

Great, it partly worked. It properly detected the address (0x4e/0x4f)
and the family. Contrary to my expectations, it failed to find the
logical device number though, I wonder why.

Actually the key for this family is double 0x87. You are lucky that it
worked with only one (below), in most cases it won't.

               ^^^^^
This confirms my earlier guess that this chip was designed by Fintek,
despite the Epox top marking.

Now I'd like to understand why sensors-detect didn't find the logical
device number. Please run the following command and provide the output
(assuming you use bash as your shell, and as root):

for ldn in `seq 0 15` ; do echo "=/ LDN=$ldn /=" ; isadump -y -k 0x87,0x87 0x4e 0x4f $ldn ; done

This will dump the first 16 logical devices (there are rarely more.) We
are looking for a logical device with 0x295 at 0x60. sensors-detect
would have detected that so I expect some trick though.

Yes, I think this is a good idea, both interesting for the student and
useful for the user waiting for this chip to be supported.

There's nothing like the uGuru :p

I'd suggest working off the f71805f driver, as it supports a Fintek
chip so the Super-I/O code should be very similar.

> Also are there datasheets of similar (fintek) superio chips available 
> somewhere, those could be of great help.

The Fintek datasheets are unfortunately not publicly available as far
as I know. But Winbond has good datasheets and the Super-I/O mechanism
is pretty standard, so you can start from there (see
Documentation/hwmon/w83627hf for URLs). Or you can simply look at the
f71805f driver code, I would hope it is clear enough.

BTW the Super-I/O mechanism is essentially based on Intel's LPC
specification, which is publicly available here:
  http://www.intel.com/design/chipsets/industry/lpc.htm
But it's highly technical and you don't really need to know the details
to write a driver.

Hope that helps,

Forgot to copy paste the last line:
(logical device 4 has address 0x295, could be sensors)

Ahhhh, so it DID work perfectly! Good news.

Now the next step is to add proper detection to sensors-detect. Can you
please provide a patch? It should be as easy as adding an entry into
@superio_ids. devid is the value at 0x20 in the dump above, so 0x0541
for this Epox chip. Set the driver to "to-be-written" until the driver
has been written.

Thanks,

Hi all,

I have been trying to find what some of the other fields mean this is what I
have found out so far.

The f8 and f9 seem to contain the temperature at which the system shuts
down.
5d-5e are the fintek ID, discovered by Jean.

Tried to find the fields for fan control and found the following:
When setting the fan control, was disabled the field 96 a3-a5 a7-a9 and
ab-ae changed. A3 and ab contain the same value, which I set in the bios,
and is the percentage of max rpm at which the cpu fan can operate. Seems
that the fields a4 and a5 are the max rpm of the fan a4 is the MSB and a5
LSB. The fields get updated when a higher rpm is detected.
Ab is  fast fan speed percnatge of max, ac field is the half fan speed, ad
and ae are the lowest fanspeed setting which I can't change but are 30% of
max.
A6, a7 and a8 are the temperatures at which the fanspeed will increase.

Haven't found out why field 96 changed maybe to say that fan temps and
speeds have been set?

Below are two isadumps which I used two discover the changes, first one
before setting fan control second is after.

That kind of reverse-engineering work is interesting (even though in a
perfect world we shouldn't have to do it), however I think it is more
important to first implement a driver with the basic monitoring
functions for which Epox provided the specifications to Age. It will
also be easier for you to start with something which is documented,
even lightly.

Note that I am unlikely to accept undocumented fan control functions in
the mainline kernel anyway. I don't want to put the user's system at
risk, and I don't want to encourage manufacturers to keep their
documentation secret.

Thanks,

Define undocumented, if undocumented means the chip can do it, but the 
motherboard manufacturer didn't implement this in its drivers for other 
OS and BIOS, then I agree with you. However here the settings can be 
controlled through the bios, thus I believe we should allow modifying 
them from lm-sensors too (to the limits the bios allows and no more). 
This ofcourse assumes we manage to find out exactly how these work, to 
the point where we can say this setting in the BIOs matches that and 
that byte in X increment units. If it stays as vague as this setting 
influences those bytes, then I fully agree with you.

Regards,

Hans

Hehe, I agree expected some reaction from you ;)

If we can use the BIOS to find out additional chip features, and these
are straightforward enough for me to feel safe, why not. However Hans
Edgington's investigation didn't really sound as "things are easy to
understand" to me. Furthermore, I'm ready to take some (limited) risk
with extra monitoring functions, but fan speed control is something
different. If you get it wrong you can kill the hardware, so we can't
just implement it and wait for users to report. We've seen enough odd
things happen even with documented chips to imagine how bad it can get
without documentation.

Put in short, I have two objectives:
* Make it safe for the users.
* No increase to my maintenance workload.
If I feel both objectives are fulfilled, I won't object.
