A few days of wild DRI hacking. Implemented a DRM interface version ioctl and a change that required a version bump of the DRM interface. It's a small part of my evil plans to make this kernel device driver actually (gasp!) attach to a specific device.
It required as its basis a diff from another committer to have the linux DRM probe based on PCI IDs. That one ran into troubles because pci_driver type attachment is exclusive. So, if radeonfb had attached to your radeon, the DRM didn't get a chance to. Using old-style attachment it shouldn't be an issue, though. Given that I just changed the DRM over to old-style attachment on linux, I sure hope so.
DRI/DRM plans for the next week or so include vblank syncing support for 3dfx and/or sis, 64-bit cleanliness in the sis interfaces, lobotomizing some of the ioctls that are related to the DRM not being attached to a specific device, and merging the DRM to FreeBSD-current.
