Well I remember multiple drivers in the past for the tulip network chip, and for a while there where two firewire drivers too. Also those that run xen with pci passthrough have the same issue of preventing linux from grabbing a given device. It would seem that just using bind/unbind and loading all the drivers, user space could resolve the issue, but the cards parameter may be more convinient, at the expense of having to add that to the driver of course. -- Len Sorensen _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
