0f3ec4da2f Retire vd_maskbitbltchr. The same functionality can be obtained by testing
for mask != NULL in vd_bitbltchr, which all implementations of vd_bitbltchr()
were doing anyway.

9ed297c83c Retire various intertwined bits of fbd(4) and vt_fb, in particular the
pixel modification indirection. No actual drivers use it and those that
might (e.g. creatorfb) use custom implementations of vd_bitbltchr().

c529ffef57 Add a simple unaccelerated vt(4) framebuffer driver for Sun framebuffers
handled by creator(4) (Sun Creator 3D, Elite 3D, etc.). This provides
vt(4) consoles on all devices currently supported by syscons on sparc64.
The driver should also be easily adaptable to support newer Sun framebuffers
such as the XVR-500 and higher.

Many thanks to dumbbell@ (Jean-Sebastien Pedron) for testing this remotely
during development.

60d7ea3d32 Allow console drivers active from early boot to be used with xf86-video-scfb,
rather than only drivers attached later on. This involves a small amount of
code duplication with dev/fb/fbd.c, which will fixed later on.

Also improve performance of vt_blank() by making it not read from the
framebuffer unnecessarily.

3da1cf1e88 Extend the meaning of the CTLFLAG_TUN flag to automatically check if
there is an environment variable which shall initialize the SYSCTL
during early boot. This works for all SYSCTL types both statically and
dynamically created ones, except for the SYSCTL NODE type and SYSCTLs
which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to
be used in the case a tunable sysctl has a custom initialisation
function allowing the sysctl to still be marked as a tunable. The
kernel SYSCTL API is mostly the same, with a few exceptions for some
special operations like iterating childrens of a static/extern SYSCTL
node. This operation should probably be made into a factored out
common macro, hence some device drivers use this. The reason for
changing the SYSCTL API was the need for a SYSCTL parent OID pointer
and not only the SYSCTL parent OID list pointer in order to quickly
generate the sysctl path. The motivation behind this patch is to avoid
parameter loading cludges inside the OFED driver subsystem. Instead of
adding special code to the OFED driver subsystem to post-load tunables
into dynamically created sysctls, we generalize this in the kernel.

Other changes:
- Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask"
to "hw.pcic.intr_mask".
- Removed redundant TUNABLE statements throughout the kernel.
- Some minor code rewrites in connection to removing not needed
TUNABLE statements.
- Added a missing SYSCTL_DECL().
- Wrapped two very long lines.
- Avoid malloc()/free() inside sysctl string handling, in case it is
called to initialize a sysctl from a tunable, hence malloc()/free() is
not ready when sysctls from the sysctl dataset are registered.
- Bumped FreeBSD version to indicate SYSCTL API change.

8122a592ee Provide basic glue to allow syscons to be used on MIPS, modelled
on PowerPC support.  This was clearly not something syscons was
designed to do (very specific assumptions about the nature of VGA
consoles on PCs), but fortunately others have long since blazed
the way on making it work regardless of that.

fc9174db51 On certain newer Intel Atom based motherboards, for instance the
D2500CC which I have, syscons in text-mode fails to show the expected
contents due to write errors into video-memory.

At least one of the causes is that we copy from syscons internal buffer
to the video memory with optimized bcopy(9) which uses >16bit operations.

Until now, 32bit and wider operations have always worked on the video
memory, but since I cannot find a single source which says that this
SHALL work, and since these chipsets/bugs are now out there, this
commit changes syscons to always use 16bit copies on i386 & amd64.

This may be relevevant for PR's:
	166262
	166639
and various other bug reports floating elsewhere on the net, but
I lack hardware to test those.

4b7ec27007 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.

bda8e754a1 Make sparc64 compatible with NEW_PCIB and enable it:
- Implement bus_adjust_resource() methods as far as necessary and in non-PCI
  bridge drivers as far as feasible without rototilling them.
- As NEW_PCIB does a layering violation by activating resources at layers
  above pci(4) without previously bubbling up their allocation there, move
  the assignment of bus tags and handles from the bus_alloc_resource() to
  the bus_activate_resource() methods like at least the other NEW_PCIB
  enabled architectures do. This is somewhat unfortunate as previously
  sparc64 (ab)used resource activation to indicate whether SYS_RES_MEMORY
  resources should be mapped into KVA, which is only necessary if their
  going to be accessed via the pointer returned from rman_get_virtual() but
  not for bus_space(9) as the later always uses physical access on sparc64.
  Besides wasting KVA if we always map in SYS_RES_MEMORY resources, a driver
  also may deliberately not map them in if the firmware already has done so,
  possibly in a special way. So in order to still allow a driver to decide
  whether a SYS_RES_MEMORY resource should be mapped into KVA we let it
  indicate that by calling bus_space_map(9) with BUS_SPACE_MAP_LINEAR as
  actually documented in the bus_space(9) page. This is implemented by
  allocating a separate bus tag per SYS_RES_MEMORY resource and passing the
  resource via the previously unused bus tag cookie so we later on can call
  rman_set_virtual() in sparc64_bus_mem_map(). As a side effect this now
  also allows to actually indicate that a SYS_RES_MEMORY resource should be
  mapped in as cacheable and/or read-only via BUS_SPACE_MAP_CACHEABLE and
  BUS_SPACE_MAP_READONLY respectively.
- Do some minor cleanup like taking advantage of rman_init_from_resource(),
  factor out the common part of bus tag allocation into a newly added
  sparc64_alloc_bus_tag(), hook up some missing newbus methods and replace
  some homegrown versions with the generic counterparts etc.
- While at it, let apb_attach() (which can't use the generic NEW_PCIB code
  as APB bridges just don't have the base and limit registers implemented)
  regarding the config space registers cached in pcib_softc and the SYSCTL
  reporting nodes set up.

we just fail shadowing altogether if that is the case because the shadowed

a73f383ee9 Add an experimental feature to shadow video BIOS. Long ago, this trick was
supported by many BIOSes to improve performance of VESA BIOS calls for real
mode OSes but it is not our intention here.  However, this may help some
platforms where the video ROMs are inaccessible after suspend, for example.
Note it may consume up to 64K bytes of contiguous memory depending on video
controller model when it is enabled.  This feature can be disabled by
setting zero to 'debug.vesa.shadow_rom' loader tunable via loader(8) or
loader.conf(5).  The default is 1 (enabled), for now.
