Move the pvh_xencons so xen_machdep.c as early_xencons, so it can be
used in the future as early ouput for plain PV guests too.
Support non-VGA framebuffers for Xen dom0. This is mandatory for graphic
console on EFI-only hardware.
Add a xen_genfb_getbtinfo() function which will return a btinfo_framebuffer
structure, filled in with parameters provided by Xen
when runing as a Xen dom0, call xen_genfb_getbtinfo() instead of
lookup_bootinfo(BTINFO_FRAMEBUFFER) when adding properties to the
PCI graphic device (when genfb is attached) and in x86_genfb_init()
when genfb is used as console.
x86/x86/consinit.c: If running as a Xen dom0, use xen_genfb_getbtinfo()
to check if we have a genfb console
xen/x86/consinit.c: support genfb as possible console
xen/x86/consinit.c: use the hypervior IO as console until a better one
is found. If the hypervisor is using a serial port for boot messages,
we'll get NetBSD's boot message on the serial port too until
the real console takes over.
xen/x86/autoconf.c: rework device_register() to be closer to the x86 version.
Especially make sure that device_pci_register() is called.
Make sure to always fall back to xen_early_console, even for dom0
Enable genfb in DOM0 kernels
Add ext_lfb_base to dom0_vga_console_info, from recent Xen. We know if it's
present or not by checking dom0.info_size
Add XENPF_get_dom0_console, which gets a dom0_vga_console_info stucture
from the hypervisor. To be used by PVH dom0 kernels.
XENPVH option is not used. Fix consinit.c to use XENPVHVM as intended
and XENPVH from defflag
for a dom0 PVH, the dom0_vga_console_info structure has to be retrieved
using a platform hypercall; do so in the XENPVHVM case.
Now genfb works in a PVH dom0 running on Xen 4.18 (Xen 4.15 doesn't support
this platoform op, so no way to make it work here).
