I have done some reasearch on ACPI spec, tables etc. Now my query is, I have to interface and chip on I2c. I have to provide its entry in DSDT , but some basic stuff is not clear to be in DSDT.
GNVS system memory shows some memory mapped registers ( like GP0A, GP0L, OSYS) . What are these , where do I get information on these. As far as I understand these are information passed by BIOS to OS . But if I need to use any of these , then how do I do that. Where is the documentation for these available ? Iam using intel E3900 processor for my design.
