From: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Hi all, This series adds a new microcode driver for Xen. The Xen hypervisor can deal with all the low-level details of doing a microcode update (Intel vs AMD, doing all the physical CPUs present on the system, current and future, etc), so all the driver has to do is make a hypercall to upload the microcode into Xen. This only

Hi Ingo, Here''s the chunk of patches to add Xen Dom0 support (it''s probably worth creating a new xen/dom0 topic branch for it). A dom0 Xen domain is basically the same as a normal domU domain, but it has extra privileges to directly access hardware. There are two issues to deal with: - translating to and from the domain''s pseudo-physical addresses and real machine
