Maybe just add a DRM command to do it, so that old X versions (who don't
know about it) will just do it by hand, and then new X versions can do
if (drm_ioctl(fd, DRM_SETUP_THE_DAMN_RESOURCES) < 0) {
/*
* I don't know what errno the drm-ioctl actually
* returns for unrecognized commands, so this is
* just an example
*/
if (errno == ENOTTY) {
old kernel: do it by hand
}
}
which allows us to go forward in a sane way, and finally leave the broken
X PCI-configuration-by-hand crap behind.
It doesn't help of course, the fb drivers also pci_enable the devices,
really X needs a kicking square, I'm trying to figure out some sort of fix
here, but X does't some really stupid things with PCI resources...
We really need a userspace way to pci_enable_device that X can call (via
sysfs) so for cards that don't have a DRM or fb loaded we still get
something..
