So it's far from what I would call OS- or Except that there isn't an ioctl() symbol referenced in that binary module (via 'nm'). It doesn't use external DRM as far as I know (from asking a person about it), nor AGP. The only AGP function that I see referenced in that module is the OS independent function to get the address of the card itself. The intuition here and from the supporting evidence from the 'nm' output is that you pass it the address of the card and the binary module does all of that stuff automatically. The driver was written when DRM and DRI, was kind of screwy in the open source community so they included a lot proprietary code containing their own DRM and DRI that can't be publically released. (info also from the same person) I understand somebody has got the 2d side of this working in FreeBSD, but the 3d stuff crashes still. > architecture-independent stuff.

Last time I heard, XFree had their own linker system. It could mean they're a bit immune to ELF differences in FreeBSD and Linux. This is just speculation. bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
