Allow a PVH dom0 to use VGA as console: make xen_pvh_consinit() return 1 if
it handles the console and 0 otherwise (especially when console=tty0 or
console=pc is present on the command line).

In consinit() fallback to native console selection if xen_pvh_consinit()
returns 0.

Hanble dom0 console. This one doesn't need a ring to be mapped, and
can be used earlier.

Revision 1.1 / (download) - annotate - [select for diffs], Sat May 2 16:44:36 2020 UTC (3 years, 1 month ago) by bouyer
Branch: MAIN

Introduce Xen PVH support in GENERIC.
This is compiled in with
options XENPVHVM
x86 changes:
- add Xen section and xen pvh entry points to locore.S. Set vm_guest
  to VM_GUEST_XENPVH in this entry point.
  Most of the boot procedure (especially page table setup and switch to
  paged mode) is shared with native.
- change some x86_delay() to delay_func(), which points to x86_delay() for
  native/HVM, and xen_delay() for PVH

Xen changes:
- remove Xen bits from init_x86_64_ksyms() and init386_ksyms()
  and move to xen_init_ksyms(), used for both PV and PVH
- set ISA no-legacy-devices property for PVH
- factor out code from Xen's cpu_bootconf() to xen_bootconf()
  in xen_machdep.c
- set up a specific pvh_consinit() which starts with printk()
  (which uses a simple hypercall that is available early) and switch to
  xencons when we can use pmap_kenter_pa().
