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 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

Patrick, there following patches fix xenpaging for me. Granttable handling is incomplete. If a page is gone, a GNTST_eagain should be returned to the caller to inidcate the hypercall has to be retried after a while, until the page is available again. Please review.

This patch series implements the Linux Xen guest in terms of the paravirt-ops interface. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual block
