bouyer | 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.

bouyer | branches: 1.25.20;
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().

cherry | This change modifies the mainbus(4) entry point for all x86 sub-archs
in the following way:
i) It provides a unified entry point in
x86/x86/mainbus.c:mainbus_attach()
ii) It carves out the preliminary bus attachment sequence that is
common to all sub-archs into
x86/x86/mainbus.c: x86_cpubus_attach()
iii) It consolidates the remaining pathways as internal callee
functions so that these may be called piecemeal if required. A
special usecase of this is XEN PVHVM which may need to call the
native configure path, the xen configure path, or both.
iv) It moves the driver private data structures from
i386/i386_mainbus.c to an x86/ level one. This allows for other
sub-arch's to do similar, if needed. (They do not at the moment).
v) For dom0 kernels, it enables 'acpi0 at mainbus?' and
'acpi0 at hypervisorbus'. This serves two purposes:
a) To demonstrate the possibility of dynamic configuration tree
traversal ordering changes.
b) To allow for the common acpi_check(self, "acpibus") call in
x86/mainbus.c to not barf when it is called from the dom0 attach
path. We allow for the acpi0 device to be a child of mainbus with
the changes to amd64/conf/XEN3_DOM0 and i386/conf/XEN3PAE_DOM0
without actually probing further in the code. This path will later
be pursued in a PVHVM boot codepath.
There should be no operative changes with this change. If there are,
please complain loudly.

Do not call setroot() from MD code and from MI code, which has
unwanted sideeffects in the RB_ASKNAME case. This fixes PR/46732.
No longer wrap MD cpu_rootconf(), as hp300 port stores reboot information
as a side effect. Instead call MI rootconf() from MD code which makes
rootconf() now a wrapper to setroot().
Adjust several MD routines to set the global booted_device,booted_partition
variables instead of passing partial information to setroot().
Make cpu_rootconf(9) describe the calling order.

| 12-Feb-2009 |
cegger | Make Dom0/DomU boot with root-on-nfs when 'bootdev' parameter is missing or wrong.
In this case, we get prompted for the root device.
Make sure that nfs_bootstatic_callback is initialized or we will miss the nfsroot bootparameter,
causing a boot failure even when root device is correct.

cegger | branches: 1.7.2;
change nfs boot behaviour to automatically try next boot method if boot information are incomplete to succeed.
That way, it is possible combine static and dhcp boot:
For example, to boot diskless you can specify the nfs-server and the rootpath statically. All other information will be taken via dhcp.
Patch has been presented on port-xen, tech-kern and tech-net:
http://mail-index.netbsd.org/port-xen/2008/10/24/msg004488.html

bouyer | Prepare for xenamd64:
- kill xen/i386/identcpu.c, use i386/i386/identcpu.c instead (with a few
#ifndef XEN)
- move some files that can be shared between i386 and amd64 from
xen/i386 to xen/x86 (or to xen/xen for non-cpu-specific code)
- split assembly out of xen/include/hypervisor.h to xen/include/hypercalls.h
- use <xen/...> instead of <machine/...> for cpu-independant include files.
more work needed here, i386-specific files should got out of arch/xen to
arch/xeni386, and more code shared with arch/i386.

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).
