313ef9368f vt(4): Change the terminal and buffer sizes, even without a font
This fixes a bug where scroll lock would not work for tty #0 when using
vt_vga's textmode. The reason was that this window is created with a
static 256x100 buffer, larger than the real size of 80x25.

Now, in vt_change_font() and vt_compute_drawable_area(), we still
perform operations even of the window has no font loaded (this is the
case in textmode here vw->vw_font == NULL). One of these operation
resizes the buffer accordingly.

In vt_compute_drawable_area(), we take the terminal size as is (ie.
80x25) for the drawable area.

The font argument to vt_set_border() is removed (it was never used) and
the code now uses the computed drawable area instead of re-doing its own
calculation.

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.

cb81897a72 vt(4): When creating a window buffer, fill it entirely
... not just the visible part.

This fixes a bug where, when switching from eg. vt_vga to vt_fb (ie. the
resolution goes up), the originally hidden, uninitialized area of the
buffer is displayed on the screen. This leads to a missing text cursor
when it's over an unitialized area.

This was also visible when selecting text: the uninitialized area was
not highlighted.

Internally, this area was zeroed: characters were all 0x00000000,
meaning the foreground and background color was black. Now, everything
is filled with a space with a gray foreground color, like the visible
area.

While here, remove the check for the mute flag and always use
TERMINAL_NORM_ATTR as the character attribute (ie. gray foreground,
black background).

946d0288f2 vt(4): Fix cursor handling in vt_flush()
There were situations where the cursor was not erased/redrawn or its

At the same, add a function to determine if the cursor covers a given

This new function should be paired with a new state in struct vt_device,
called vd_mshown, which indicates if the cursor should be displayed.
This again simplifies vd_bitblt_text_t callback's API.

bdcaf97c3e vt(4): Add new vd_bitblt_text_t callback, and implement it for vt_vga
Compared to the deprecated vd_bitbltchr_t callback, vd_bitblt_text_t
receives:
    o  the whole text buffer
    o  the dirty area
    o  the mouse cursor (map, position, colors)

This allows the backend to perform optimization on how to draw things.
The goal is to remove vd_bitbltchr_t and vd_putchar_t, once all driver
are converted (only vt_vga is included in this commit).

In vt_vga, this allows to draw the text and the cursor in one pass,
without ever reading from video memory (because it has all the context).
The main benefit is the speed improvement: no more slideshow during
boot!

Other bugs fixed in vt_vga are:
    o  left-most characters are drawn properly (the left-most pixels were
       missing with bold characters and some wide letters such as 'm')
    o  no more black square around the cursor
    o  no cursor flickering when the text is scrolling

There are still many problems to fix: the known issues are marked with
"FIXME" inside the code.

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).

232490c660 Make mmap() of the console device when using ofwfb work like other supported
framebuffer drivers. This lets ofwfb work with xf86-video-scfb and makes
the driver much more generic and less PCI-centric. This changes some
user-visible behavior and will require updates to the xorg-server port
on PowerPC when using ATI graphics cards.

351e92cc2d Allow efifb to be used with xf86-video-scfb. This is important for EFI
systems without either a CSM or real graphics drivers, such as my Lenovo

dealt with later.

b85beee188 On my Lenovo laptop, the firmware maps the EFI framebuffer with MTRRs set

up, remap the framebuffer as write-combining. This reduces boot time on my
laptop by 60% when booting with EFI.

7344ee184b In order to get vt(4) a bit closer to the feature set provided by sc(4),
implement options TERMINAL_{KERN,NORM}_ATTR. These are aliased to
SC_{KERNEL_CONS,NORM}_ATTR and like these latter, allow to change the
default colors of normal and kernel text respectively.
Note on the naming: Although affecting the output of vt(4), technically
kern/subr_terminal.c is primarily concerned with changing default colors
so it would be inconsistent to term these options VT_{KERN,NORM}_ATTR.
Actually, if the architecture and abstraction of terminal+teken+vt would
be perfect, dev/vt/* wouldn't be touched by this commit at all.

With this change and previous work from ray@ it will be possible to put
both in GENERIC, and have one enabled by default, but allow the other to
be selected via the loader.

(The previous implementation had separate kern.vt.disable and
hw.syscons.disable tunables, and would panic if both drivers were
compiled in and neither was explicitly disabled.)

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.

c6317b8376 Correct vt(4) border calculations on font switch
If a vt(4) font does not exactly fit the screen dimensions, the console
window is offset so that it is centered.  A rectangle is drawn at the
top, left, right, and bottom of the screen, to erase any leftovers that
are outside of the new usable console area.

If the x offset or y offset is 0 then the left border or top border
respectively is not drawn.  The right and bottom borders may be one
pixel larger than necessary due to rounding, and are always drawn.

Prior to this change a 0 offset would result in a panic when calling
vt_drawrect with an x or y coordinate of -1.
