[lm-sensors] i2c-i801 Interrupt Support

[lm-sensors] i2c-i801 Interrupt Support

[Ivo Manca]

Hey Mark,

We're three students from the TH-Rijswijk following a embedded software 
college (under supervision of Hans de Goede), trying to add Interrupt 
Handling support to the current i2c i801 bus driver. After looking for 
more information, we've found a message coming from you at Sunday 28 
November 2004 concerning a complete rewrite of the i2c-i801 for 2.6.x 
(http://archives.andrew.net.au/lm-sensors/msg28496.html)
This patch added interrupt handling support the the driver.

However, this code does not seem to be present anymore.

How come this code is no more?
We're unable to find any concrete information.

Thanks in advance,

Ivo Manca
Bert Fraterman
Sander Vermin

The question is why wasn't the above code ever merged into the mainline? If you 
read the thread you will find various comments about it causing problems on 
varioussystems, triggering SMI interrupts and other nastiness there.

Hans

Well, the post above contains the rewritten driver in question, what
else do you need?

I am very interested in having an interrupt-driven i2c-i801 driver. If
you come up with something, I will be very happy to test it on my
various Intel-based systems. I have one ICH3M, two ICH5 and one
ICH7-based systems available for testing.

Thanks,
