ACPI 2.19 Documentation inconsistency

Postby Alan Beagley » Wed Mar 28, 2007 17:52

I've downloaded the new 2.19 files and read the docs. but haven't yet tried the drivers.

Problem: Although Q&A 40 hasn't been updated and thus still says not to use ACPI snooper on NVidia chipset, the Whatsnew file includes the line:

"* snooper: fix for nvidia high irq"

So do we or don't we use the snooper for systems using the nVidia chipset (mine is an Asus A8N-E motherboard)? What is the advantage of using it, and *how* do we use it we choose to do so?

try boot with snooper and post results.

by default you don't need snooper with NVidia X2.

We can change IRQ for APIC. Via directive LINK in acpi.cfg. Warning, this link must has IRQ >15 in possible IRQ
