There's an argument that we should automatically apply these patches and build AGP and DRM support as modules for our xen0 kernels. It would be good to know which drivers have actually been tested and work. Rik: did you have any luck feeding the agpgart and drm patches up stream? > I would > appreciate it if someone who knows the xen agp subsystem (in > particular > the agp_acquire_backend) better would look over the intelfb.patch and > post any improvements (I don't like taking out the checks made on > agp_acquire_backend(), but with them left in, I get "intelfb: cannot > acquire agp"). Which of the error codes is it returning? There's nothing special about AGP support on arch xen, its just that Xen is rather stricter about what drivers are allowed to get away with, requring some fixes. int agp_backend_acquire(void) { if (agp_bridge->type == NOT_SUPPORTED) return -EINVAL; if (atomic_read(&agp_bridge->agp_in_use)) return -EBUSY; atomic_inc(&agp_bridge->agp_in_use); return 0; } Ian ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
