[lm-sensors] dme1737: Base address not set / How to do the BIOS' job

[lm-sensors] dme1737: Base address not set / How to do the BIOS' job

[Stefan Steuerwald]

[-- Attachment #1.1: Type: text/plain, Size: 566 bytes --]

Hi lm-sensor,

I have an embedded system with a SCH3114 Super-I/O sitting at 0x2E on the
LPC bus.
My BIOS does not support this chip, hence it goes uninitialized on boot.
Consequently, when I load the dme1737 kernel module, it says "Base address
not set".

For lack of a better BIOS, I think I have to manually poke around the
SCH3114's registers to set base address, IRQ numbers, whatever else.
Correct?
Maybe anybody can point me to some code that may be doing something similar?
I'd like to enable the Super-I/O's USARTs and LPT, above all.

Thank you,
  Stefan.

Yes,

But why the BIOS does not support that? Maybe its not used for monitoring at
all. Maybe you have added to system somehow? (on some strange addon card?)

What southbridge you have? Vendor/model?

Thanks,
Rudolf

Thank you Rudolf,

I have a credit-card sized cpu module with an Intel Atom Z530 and a SMSC3114
Super-IO on a baseboard. The BIOS on the CPU module is a minimal one and
apparently has support only for some Winbond Super-IO and little else.

Now that you have confirmed my suspicion...
I browsed through what sensors-detect does and have been able to use some
outb/inb sequence to set the base address of the chip and activate it. When
I use dme1737 with the force_start=yes module parameter, I am getting
voltage and temp readings. Nice!
Let's see if I can get the rest working without crashing the system.

Thanks again,
  Stefan.

Hi,

If you tell me cat /proc/cpuinfo and what type of SB you have I might tell some 
IO addresses which are safe to use ;)

I think you can setup there usually something around 0x300 like 0x290. Assuming 
that the rest of superio lives at 0x2e/0x2f or so...

Btw what BIOS is that?

Rudolf

Have attached cpuinfo and ioports.
I chose 0x0600 as the base address for the SCH3114 SuperIO, seems to work so
far. Better suggestions welcome ;-)

Thank you!
  Stefan.

Hi,

Yes 600 looks good to me also.
