xen: add missing definitions in include/xen/interface/vcpu.h which ia64/xen needs

2008-04-24T21:57:32Z

Add xen handles realted definitions for xen vcpu which ia64/xen needs. Pointer argumsnts for ia64/xen hypercall are passed in pseudo physical address (guest physical address) so that it is required to convert guest kernel virtual address into pseudo physical address. The xen guest handle represents such arguments. Signed-off-by: Isaku Yamahata Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

xen: fix incorrect vcpu_register_vcpu_info hypercall argument

2007-10-16T18:51:31Z

The kernel's copy of struct vcpu_register_vcpu_info was out of date, at best causing the hypercall to fail and the guest kernel to fall back to the old mechanism, or worse, causing random memory corruption.

xen: Place vcpu_info structure into per-cpu memory

2007-07-18T15:47:45Z

An experimental patch for Xen allows guests to place their vcpu_info structs anywhere. We try to use this to place the vcpu_info into the PDA, which allows direct access. If this works, then switch to using direct access operations for irq_enable, disable, save_fl and restore_fl. Signed-off-by: Jeremy Fitzhardinge Cc: Chris Wright Cc: Keir Fraser

xen: Add Xen interface header files

2007-07-18T15:47:42Z

Add Xen interface header files. These are taken fairly directly from the Xen tree, but somewhat rearranged to suit the kernel's conventions. Define macros and inline functions for doing hypercalls into the hypervisor. Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Ian Pratt Signed-off-by: Christian Limpach Signed-off-by: Chris Wright
