Are there any plans to support ITE IT8720 Super IO chip? I recently bought a Gigabyte EP45 board that uses this IO chip.

I also bought such a Gigabyte board recently. I am very interested in support for this IO chip. I am also willing to help in testing.

I have added an entry for the IT8720 on the Devices page, and detection for that chip to sensors-detect. Without a datasheet there's not much more we can do.

We have a datasheet now.

I'm working on adding support for the IT8720 to the it87 driver. Hope to post some code for testing "soon".

Hi "fmyhr",

Did you get a chance to work on this? I just buy a brand new ASUS M3A78 motherboard, and I have the same issue. Is there a way for me to help you?

  • version set to kernel

A patch contributed by Jean-Marc Spaggiari is now available for testing. I'll attach it to this ticket. This patch will go into Linux kernel version 2.6.29.

Cool. Thank you! Need to go figure out sensors.conf.

The patch has gone upstream now. Frank, I think we can close this ticket now?
