I've been implementing the ACPI for the ep80579 and so far it is not
going very well. Linux refuses to boot unless I use acpi=off or
acpi=ht as boot parameters. acpi=ht seems to display my ACPI ioports
in proc/ioports as expected ( the ioports addresses are all mapped to
the ACPI BAR ). Without to disable acpi the kernel complains that the
0xE0000000 range is not a reserved range and the MMCONF is not
supported and then hangs.
It should not hang. The complain is only about e820 map is not reserved. I made
recently a small patch for this for K8M890. Simply the problem seems elsewhere
to me.
The DSDT been dumped from the legacy BIOS using acpidump and this is
what I am including in the build process to test. Actually I've based
my code on the mainboard\intel\eagleheigths.
Please try to develop minimalistic DSDT based on M2V-MX SE and read the ACPI
guide on the wiki.
You need to have linux working first and then go for windows.
Please try to read the wiki pages and then ask so we can improve the pages.
