It has been around since 4.0 as "device agp" in the |config file. You can also add "agp_load=YES" to the /boot/loader.conf |file if you do not wish to recompile. Oh, I didn't realize that "device agp" and "agpgart" were the same. I have both "device agp" compiled into my kernel, and "agp_load=YES" in my loader.conf. |It has lagged behind some when it comes to support. I believe all VIA, |Intel, SiS, and ALi bridges are supported, as well as the AMD 751 |bridge. I have a 761, and I am not sure whether it works or not (I have |to modify the source to get it to detect). | |Anyway, it puts a /dev/agpgart entry into the filesystem. This is |basically the door that the app uses to set up apertures in system memory |for AGP transfers. I also have an AMD 761 (ASUS A7M266 MB). Could you mail me your patches? Sounds like that northbridge detection support is what I'm missing (or at least one piece of it). I did notice before that "grep 'AMD.*761' /usr/src/sys/pci/*" turned up no hits in my -stable kernel tree, and "cat < /dev/agpgart" gives me "Device not configured." So this was on my list of suspects to investigate.
