windfarm for PM72/PM73/RM31

windfarm for PM72/PM73/RM31

Hi,

I'm working on writing a windfarm driver for the PM72/PM73/RM31 boxes,
amongst some other windfarm work I'm doing, and I have a few quick
notes/questions:

Process so far/TODO list:
- I've got the ds1775 and max6690 chips returning all of their data on
  PowerMac11,2 and PowerMac7,3. I need to change the detection code for the
  max6690 sub-nodes (it has both internal and external temps) as they
  don't exist on PM72.
- Need to write windfarm sensor drivers for: ds1631, ad7417, lm87
- Flesh out my windfarm_pm72 more - it's based on the therm_pm72
  constants and the pm112 module for now, completely untested until I
  have the sensors and controllers hooked up.

Questions:
1. Message naming consistancy - there are a number of printk/DBG
statements that seem to flip randomly between using a prefix of
'windfarm:' or 'wf:', and then some that omit it entirely.
Any consensus on which one is preferred?

2. Could somebody please send me a tarball of /proc/device-tree/ from a
RackMac3,1 unit? I've got the data for PM72/73 already.

Hello,

I own an iMac G5 rev C (iSight) with a PowerMac 12,1 included. Do you =20=

intend to make support for it ? I will be happy to help you :)

Thank you.

I'd like to start on the PM72 stuff first, but please tar up your
/proc/device-tree/ directory and email it to me, and I can see about it.

If Apple stuck to the same sensors (max6690, lm75. lm87, ds1775, ds1631,
ad7417), it should be reasonable simple to add your machine afterwards.

Is there actually a reasonable archive of the OF node trees somewhere?
It think it might be handy in developing drivers in future. I've
presently got: PowerBook4,3 PowerMac7,2 PowerMac7,3 PowerMac11,2

I'm not sure we can publically post them, there might be some apple
copyright lurking around. I have a fairly big archive here too.

Thanks for sending it to me.

The sensor portion of yours is done, it fit right into my existing code
(three lm75 and two max6690, with the dual temps on max6690 being very
important).

The PID params portion will come together a bit later, please bug me by
Wednesday next week if I haven't posted anything.

Now we are Friday, what can we test ? ;) Sadly, my iMac G5 is under
repair for quite some times (it crashes during compilation of mesa
packages and never woke up).

So what'sup ? :)

Unfortunately I got a nasty cold, so I've been sick and need to catch up
on work stuff first.

In terms of progress, I'm still working on the windfarm_ad7417_sensor
portion, and the windfarm_pm* portions come after that.

I'll try to get a git repo up this evening, for other folk to test stuff
from.

I'll get back my iMac G5 rev C in the next hours. So i'll be able to
test code. Have done some work about windfarm ?

Regards.

Étienne.

Not really... I tended to use "wf" for debug and "windfarm" for normally
visible messages but I may not have been totally consistent.

I'll do so tomorrow, ping me if you don't hear from me.
