[PATCH-for-9.0 00/10] hw/xen: Have most of Xen files become target-agnostic

Posted by Philippe Mathieu-Daudé 1 year ago

Hi,

After discussing with Alex Bennée I realized most Xen code
should be target-agnostic. David Woodhouse confirmed that
last week, so I had a quick look and here is the result.

More work is required to be able to instanciate Xen HW in
an heterogeneous machine, but this doesn't make sense yet
until we can run multiple accelerators concurrently.

Only build-tested.

Regards,

Phil.

Philippe Mathieu-Daudé (10):
  sysemu/xen: Forbid using Xen headers in user emulation
  hw/xen/xen_arch_hvm: Rename prototypes using 'xen_arch_' prefix
  hw/xen: Merge 'hw/xen/arch_hvm.h' in 'hw/xen/xen-hvm-common.h'
  hw/xen: Factor xen_arch_align_ioreq_data() out of handle_ioreq()
  hw/xen: Use target-agnostic qemu_target_page_bits()
  hw/xen: Reduce inclusion of 'cpu.h' to target-specific sources
  sysemu/xen-mapcache: Check Xen availability with
    CONFIG_XEN_IS_POSSIBLE
  system/physmem: Only include 'hw/xen/xen.h' when Xen is available
  hw/xen: Extract 'xen_igd.h' from 'xen_pt.h'
  hw/xen: Have most of Xen files become target-agnostic
