| |
Something I noticed on my new AMD64 laptop with 4 gigs of RAM and a 256meg video card.
I am running 2.6.25 from Fedora 9 beta.
When i boot, I get the following messages:
Checking aperture... Node 0: aperture @ 9816000000 size 32 MB Aperture beyond 4GB. Ignoring. No AGP bridge found Your BIOS doesn't leave a aperture memory hole Please enable the IOMMU option in the bios setup Mapping aperture over 65536 KB of RAM @ c000000
Is this a bug or is the x86_64 supposed to map the video aperture into something that is 32bit addressable?
Also, there is no video settings at all on this particular laptop in bios. (It is an HP dv6700 with almost everything maxed out.)
Just curious if this is correct behavior or not. (Since I am using the xorg nv driver, it may not make any difference.)
