a985ae9b4a Add support for USB display link adapters to the FB and VT drivers.
The vtophys() function is used to get the physical page address for
the virtually allocated frame buffers when a physically continuous
memory area is not available. This change also allows removing the
masking of the FB_FLAG_NOMMAP flag in the PS3 syscons driver.

The FB and VT drivers were tested using X.org/xf86-video-scfb and
syscons.

76e2f97656 vt(4): Add support to "downgrade" from eg. vt_fb to vt_vga
The main purpose of this feature is to be able to unload a KMS driver.

When going back from the current vt(4) backend to the previous backend,
the previous backend is reinitialized with the special VDF_DOWNGRADE
flag set. Then the current driver is terminated with the new "vd_fini"
callback.

In the case of vt_fb and vt_vga, this allows the former to pass the
vgapci device vt_fb used to vt_vga so the device can be rePOSTed.

6dfa4578d6 vt(4): Use power_{suspend,resume} event handlers to implement
suspend/resume

The goal is to avoid that the vt(4) resume happens before the video
display is resumed. The original patch was provided by Andriy Gapon.

This new patch registers the handlers in vt_upgrade(). This is done
once, thanks to the VDF_ASYNC flag. I abused this flag because it was
already abused by the keyboard allocation. The event handlers then call
the backend if it provides callbacks for suspend/resume.

84d623c61e vt(4): Fix mouse cursor handling in vt_fb/creator_vt/ofwfb
There were two issues:
    1. The area given to vt_is_cursor_in_area() was adding the drawable
       area offset, something already handled by this function.
    2. The cursor was shifted on the screen by the offset of this area
       and thus was misplaced or not erased. Furthermore, when reaching
       the bottom or right borders, the cursor was either totally
       removed or not erased correctly.

19e2ce2d83 vt(4): Colors are indexed against a console palette, not a VGA palette
Rename vt_generate_vga_palette() to vt_generate_cons_palette() and
change it to build a palette where the color index is the same than in
terminal escape codes, not the VGA index. That's what TCHAR_CREATE()
uses and passes to vt(4).

The main differences between both orders are:
    o  Blue and red are swapped (1 <-> 4)
    o  Yellow and cyan are swapped (3 <-> 6)

The problem remained unnoticed, because the RGB bit indexes passed to
vt_generate_vga_palette() were reversed. This inversion was cancelled
by the colors inversions in the generated palette. For instance, red
(0xff0000) and blue (0x0000ff) have bytes in opposite order, but were
swapped in the palette. But after changing the value of blue (see last
paragraph), the modified color was in fact the red one.

This commit includes a fix to creator_vt.c, submitted by Nathan
Whitehorn: fb_cmsize is set to 16. Before this, the generated palette
would be overwritte. This fixes colors on sparc64 with a Creator3D
adapter.

While here, tune the palette to better match console colors and improve
the readability (especially the dark blue).

2cf9e30b6e fbd: Fix a bug where vt_fb_attach() success would be considered a failure
vt_fb_attach() currently always returns 0, but it could return a code
defined in errno.h. However, it doesn't return a CN_* code. So checking
its return value against CN_DEAD (which is 0) is incorrect, and in this
case, a success becomes a failure.

The consequence was unimportant, because the caller (drm_fb_helper.c)
would only log an error message in this case. The console would still
work.

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.
