Hi,
as you may have noticed, we have a relatively new tool called 'superiotool' (http://linuxbios.org/index.php/Superiotool) in the repository:
$ svn co svn://linuxbios.org/repos/trunk/util/superiotool
It is able to detect which Super I/O is located on your mainboard, and (if the respective code support was added), it can also dump the contents of all registers on the Super I/O:
$ superiotool -d
This will hopefully be helpful in debugging Super I/O related problems, e.g. with keyboards, systems sensors and fans, etc.
To make the tool more useful we need
- As many supported Super I/Os as possible.
Supporting new ones is relatively easy, but a bit time-consuming. You have to grab the datasheet, find out the ID/version of the Super I/O and add it in the respective file (ite.c for ITE Super I/Os, for example). For the dump functionality you have to add a (large) table with all registers and their defaults.
- One or two outputs of 'superiotool -d' for each supported Super I/O for reference, so we can compare values for different boards.
If you have one of the supported Super I/Os (see table in http://linuxbios.org/Superiotool) please run 'superiotool -d' as root, reply to this email and submit the output. We'll then link to your email (in the list archive) in the wiki page.
Thanks, Uwe.
