Hi again all, It turns out that networking really wants ordered requests, which the previous patches didn't allow. This patch changes it to a callback mechanism; kudos to Avi. The downside is that locking is more complicated, and after a few dead ends I implemented the simplest solution: the struct virtio_device contains the spinlock to use, and it's held when your callbacks get

In response to Avi's excellent analysis, I've updated virtio as promised (apologies for the delay, travel got in the way). === This attempts to implement a "virtual I/O" layer which should allow common drivers to be efficiently used across most virtual I/O mechanisms. It will no-doubt need further enhancement. The details of probing the device are left to hypervisor-specific

Hi all, These are the patches I'm planning to submit for 2.6.24. Comments gratefully accepted. Along with the usual cleanups and improvements are Jes' de-i386-ification patches, and a new "virtio" mechanism designed to be shared with KVM (and hopefully other hypervisors). Cheers, Rusty.
