PC87431 is not - need full datasheet.

[Chan Min Wai (System Administrator)]

Hello all,

I'm on Ticket #1853

Is there anyway I can help to obtain a full data sheet?
What kind of full data sheet do you need?

What should be included?

I would like to help in this, I've contact Intel Support and I think
they will help in somewhere. So please tell me what do you really want
and I'll try my best to get that. However I'll have no promise about
what I can get, but I'll try my very best on this issue.

Following by recently requests about National's PC87431 mBMC device, 
please find the following information:
1. The PC87431 is fully IPMI 1.5 compliant device with remote 
   LAN manageability support
2. The Host interface of PC87431 is IPMI 1.5/2.0 SSIF (SMBus)
3. The PC87431 supports all mandatory commands of IPMI 1.5
4. System configuration and sensor list can be read using regular IPMI 
   SDR commands
5. Specific sensor data can be obtained using IPMI "Get Sensor Reading" 
   command

More information about PC87431 can be found on:
http://www.national.com/pf/PC/PC87431M.html

The full PC87431 datasheet can be obtained under NDA.

For more information about IPMI specification, please see IPMI developers 
web-site:
http://developer.intel.com/design/servers/ipmi/index.htm

Attached are sample sources of SSIF interface implementation for PC87431.
Sources provided under BSD license agreement.

thanks for the info about the datasheet requiring an NDA.
Unfortunately this means things will be difficult.
But it may be sufficient just to get KCS over I2C working to it.

The chip uses KCS over I2C.
Corey, can we do that with the IPMI KCS driver? Do we need to
write code to register with the KCS module to route KCS messages
to a particlar address on a particular i2c bus?
How would we do that - or does IPMI already have that capability?

Once that is done, then the standard modules
bmcsensors -> i2c-ipmi -> ipmi-msghdlr -> ipmi_kcs_sm
should work.

right Corey?

Well, I don't think so.  There is no such thing as KCS over I2C.  There 
is something called the SMB interface, which is part of the newer IPMI 
driver version from openipmi.sf.net.  I really don't know that much 
about it, someone else did that work and I don't have any hardware that 
supports it.  But if you are running IPMI over I2C, that's probably what 
it is.

Oh wait, the line:
  The Host interface of PC87431 is IPMI 1.5/2.0 SSIF (SMBus)
means that it should support the standard interface that the IPMI SMB 
driver uses.  IIRC, configuring it is kind of a pain, but it is supposed 
to work.

PC87431 is not - need full datasheet.

[Ilia Stolov]

The Host interface of PC87431 is IPMI 1.5/2.0 SSIF - the new host
interface introduced in IPMI 2.0 spec. And as specified in the spec
the SSIF interface can be used for IPMI 1.5 and 2.0 BMCs.

Any SMBus driver should work. The SSIF is implemented on top of SMBus.

The SSIF message format:

Request:  <Slave address+W> <SMBus command = 02> <Length> <NetFn+LUN>
          <IPMI command> <IPMI command data ...>
Response: <Slave address+W> <SMBus command = 03> <Slave address+R>
          <Length> <NetFn+LUN> <IPMI command> <Complt Code> <Data ....>

However There is still one things is missing...

Driver for the "IPMI" Device in kernel...
Without that there is no way for us to even touch the ipmi chip in the

PC87431 is not - need full datasheet.

[Mark Studebaker]

so the ipmi_smb driver Corey just posted to LKML, together with his previous i2c patches,
together with http://bmcsensors-26.sourceforge.net ,
and you should be able to get sensor data from the 87431!
let us know how it works!

p.s. Corey I looked through ipmi_smb and it looks good.
this should give smbus block transfers and PEC quite a good testing.

Note that this was against 2.6.11-rc2 and you need the completion patch 
posted by Mike Waychison  at 
http://marc.theaimsgroup.com/?l=linux-kernel&m\x110669761400454&w=2 or 
the completion_timeout routine is broken.

Yes, it should.  After playing with it a while, I discovered that the 
i801 SMB interface is very sensitive to doing things just right.  But I 
think I have everything working correctly with the posted patches, it 
ran for a whole day without a single error.

I'm losing here,

I've try to compile 2.6.7

however I can't load the IPMI_SI module.
Error is as below.


IPMI System Interface driver version v31, KCS version v31, SMIC version
v31, BT version v31

with the patch + lm_sensors 2.8.7 & also 2.9.0
I've try to do a sensor-detect only the old config is being detected.
(the one that giving 127 C)... WOO (Which is the wrong value)

this is the lsmod that I'm loading

So I dont know where I'm now...

http://marc.theaimsgroup.com/?l=linux-kernel&m\x110669761400454&w=2
I'm not too sure where it fit.

I'm on an SE7210TP1-E Mobo where the sensor chip is
AD1207 & PC87431, if you need more information.

Please help

P.s is ipmi_smb really exists?

PC87431 is not - need full datasheet.

[Corey Minyard]

ipmi_smb doesn't exist in the mainstream kernel yet.  I'm working on 
getting it in; the driver and some rather large related changes to the 
I2C layer were posted on lkml (and the sensors list, too) a few days 
ago.  Those were against linux-2.6.11-rc2, not against 2.6.7, and those 
patches will almost certainly not apply against 2.6.7.

If you want to use the older smb driver, it does work, but certain 
functionality won't work, primarily things that occur at panic time like 
storing panic information in the SEL and extending the watchdog.  It's 
available at http://openipmi.sf.net.  There is a 2.6.7 version that will 
probably work, though it doesn't do automatic DMI detection so you will 
have to hand-specify the parameters.
