It might help if someone (Arnd?) wanted to propose a statement of what drivers/virt was really for. If it's for any Linux driver that upcalls to a hypervisor for any reason, then the Tilera paravirtualized drivers fit in well. If it's intended more for drivers that guests running under a hypervisor can use to talk to the hypervisor itself (e.g. managing notifications that a hypervisor delivers to a guest to cause it to shut down or take other actions), then it doesn't seem like the Tilera paravirtualized device drivers belong there, since they're just using the Tilera hypervisor synchronously to do I/O or get/set device and driver state. -- Chris Metcalf, Tilera Corp. http://www.tilera.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
