Later, we just see if the "struct mouse_cursor" pointer is set. This
avoids the need to mess with all the conditions several times; this
has been error prone.
While here, rename the variable "m" to a more meaningful "cursor",
like it's done elsewhere in the code.
r270293: Rename the "mouse_cursor" structure to "vt_mouse_cursor"
At the same time, "w" and "h" members are now called "width" and
"height". The goal is to have a more "public" structure, because it
will soon be passed as argument to a new callback, replacing
vd_bitbltchr_t.
r269471 (ray):
Fix vt_vga driver to draw not-8-bit-aligned fonts correctly.
Still one bug here: mouse left some gaps on track when moving left.
r270322:
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.

r270324: vt_vga: Clip the draw area to never draw offscreen
This fixes a bug when two windows use different fonts, but a longer-
term solution is required. The dirty area should be stored as pixels,
not character cells, because such coordinates don't have the same
meaning in all windows, when using different fonts.
r270329: Mark new mouse position as dirty only when it's actually displayed
r270331: Store cursor bitmap & colors in struct vt_device

r270336: Give the window to vd_bitblt_text_t callback
... instead of both the buffer and the font. Again, this simplifies
the API.
r270338: The offset to center the text area is per-window now
The previous global offset, based on the last loaded font, had no
meaning for other windows. This caused a shifted text area, often
partly out-of-screen.

r270342: Use the actual size of the mouse when marking its position as dirty
This fixes a bug where part of the cursor was not erased.
r270343: Remove "FIXME" about multiple locking of vt_buf in vt_flush()
After some testing, it appears that acquiring the lock once and keeping

While here, fix a typo in another comment.
r270388: vt_vga: Give only the character part of term_char_t to vga_get_cp437()
This fixes a bug where vga_get_cp437() was called with an invalid

character.
r270390: Fix a crash in vt_mark_mouse_position_as_dirty() when in textmode
In textmode, no font is loaded, thus the page fault in
vt_mark_mouse_position_as_dirty() when it wants the font width/height.
For now, create a fake area for the textmode. This needs to be
modified if vt_vga gains mouse support in textmode.
While here, fix a build failure when SC_NO_CUTPASTE is defined:
vt_mark_mouse_position_as_dirty() must not be included in this case.
r270404: Fix cursor handling in vt_flush()
There were situations where the cursor was not erased/redrawn or its
position was marked as dirty even though it's not displayed. The code
is now more straightforward.
At the same, add a function to determine if the cursor covers a given
area. This is used by backends to know if they need to draw the
cursor.
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.
r270431: vt(4): Add vd_bitblt_bmp_t callback
The code was already there in all backends, we just expose it. This is
used to display the splash screen.
r270446: Remove vd_bitbltchr_t
It's replaced by vd_bitblt_text_t, which gives more context to the
backend and allows it to perform more efficiently when redrawing a
given area.
r270448: Fix order of arguments (x <-> y) when showing the splash screen
r270485: vt_vga: Fix the display of the splash screen
r270587: Take font offset into account in vt_is_cursor_in_area()
This fixes a "General protection fault" in vt_vga, where
vt_is_cursor_in_area() erroneously reported that the cursor was over
the text. This led to negative integers stored in "unsigned int" and
chaos.
r270589: The cursor coordinates are relative to the drawn area
... not the whole screen. Don't use font offsets in
vt_mark_mouse_position_as_dirty().
This fixes a bug where the mouse position wasn't marked as dirty when
approaching the borders of the drawn area.
r270613: Store a rectangle for the drawable area, not just the top-left corner
This allows backends to verify they do not draw outside of this area.
This fixes a bug in vt_vga where the text was happily drawn over the
right and bottom margins, when using the Gallant font.
r270618: Intialize drawable area rectangle each time a font is loaded
This also fixes a problem where early in boot, the area was zero,
leading to nothing displayed for a few seconds.
r270620: vt_vga: Use Write Mode 0 to draw group of 8 pixels using 3 or more colors
This replaces the method based on Write Mode 3, which required reads
from the video memory to load the latches.
r270667: 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).
r270702: Implement basic support for KDSETMODE ioctl
With the current implementation, this allows an X11 server to tell
the console it switches a particular window in "graphics mode". This
information is used by the mouse handling code to ignore sysmouse events
in the window taken by the X server: only him should receive those
events.
r270707: Pause the vt_flush() timer when the screen is up-to-date
The timer is restarted whenever a window buffer is marked as dirty or
the mouse cursor moves.
There's still room for improvement. For instance, we should not mark a
window buffer as dirty when this window isn't displayed.
r270708: vt(4): Recompute the drawable area when the resolution changes
This was only done when the font changed.
r270720: 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.

MFC r270299 (dumbbell): vt_vga: When clearing video memory, don't read from it
The goal is to clear the video memory, in case an application drew to
it. So the content shouldn't be loaded in the latches, it can't be
trusted anyway.
Set fb_pbase properly on PowerPC in the case where we have to guess at
the right register bank for the framebuffer. Disable the assigned-
addresses path on SPARC since it is just a hack for IBM PPC systems
and was neither relevant for nor worked on SPARC anyway.
Should check fb_read method presence instead of double check for fb_write.
r269620 (nwhitehorn):
Retire various intertwined bits of fbd(4) and vt_fb, in particular the
pixel modification indirection. No actual drivers use it and those

vd_bitbltchr().
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.

MFC r270280 by dumbbell: vt(4): Pause the flush timer while swithing window
This fixes bad looking refresh when switching window: squares instead
of text, flashing screen, and so on. In the worst case, vt_flush() came
at a very inappropriate timing and the screen was not refreshed at all
(leaving squares all over the place).
This doesn't fix the flickering of the screen with vt_vga, because the
sync signal is temporarily stopped and the video memory is cleared.
MFC vt(4) mouse cursor improvements from dumbbell:
r270269:
vt(4): Handle global and per-window mouse cursor toggle in one place
Before the global flag was set/unset using the CONS_MOUSECTL ioctl,
and the per-window flag through the MOUSE_SETLEVEL or MOUSE_SETMODE
ioctls.
Also, if the cursor is already enabled/disabled, return immediatly.
This avoids to reset the cursor's position to the center of the
screen.
This matches syscons' behavior.
While here, remove a trailing space and a redundant variable
declaration.
r270271:
vt(4): Mark cursor old position as dirty before reading the dirty area
Otherwise, the redraw is done during the next vt_flush run.
r270272:
vt(4): If the cursor is globally disabled, don't mark its position as dirty
This avoids unnecessary redraw. In particular, during boot, where the
cursor is disabled and its fake position is [0;0], this triggered a
refresh of the whole screen each time vt_flush() is called.
r270273:
vt(4): If the cursor didn't move, don't mark its position as dirty
Currently, this has no effect, because the cursor is always redrawn
anyway. But this will be useful after improvements to the
vd_bitbltchr_t callback API.
The vt_device structure members used to store the position of the
cursor as of the last redraw are renamed from vd_mdirty{x,y} to
vd_mold{x,y}. The associated comment is fixed too. Also, their value
is now expressed in pixels, not in character columns/row.
r270275:
vt(4): Mark the current cursor position as dirty
Like r270273, this has no effect for now, because the cursor is always
drawn. This is in preparation of future changes to vd_bitbltchr_t API.
r270278:
vt(4): Mark cursor position as dirty when we enable/disable it
MFC r270661:

MFC r270666
Back in the days when the kernel was single threaded, testing
"vm_paging_target() > 0" was a reasonable way of determining if the
inactive queue scan met its target. However, now that other threads
can be allocating pages while the inactive queue scan is running, it's
an unreliable method. The effect of it being unreliable is that we
can start swapping out processes when we didn't intend to.
This issue has existed since the kernel was multithreaded, but the
changes to the inactive queue target in 10.0-RELEASE have made its
effects visible.
This change introduces a more direct method for determining if the
inactive queue scan met its target that is not affected by the actions
of other threads.
The UEFI framebuffer driver vt_efifb requires vt(4), so add a
mechanism for the startup routine to set the preferred console.
This change is ugly because console init happens very early in the
boot, making a cleaner interface difficult. This change is intended
only to facilitate the sc(4) / vt(4) transition, and can be reverted
once vt(4) is the default.
r268160: Fix typos in VTY constant names from r268158
r268982: Don't pass null kmdp to preload_search_info
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 Haswell laptop.
This provides working X with the small complication of a console
cursor permanently overlaid on the upper-left corner of the screen
that will be dealt with later.
r268771:
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.
On my Lenovo laptop, the firmware maps the EFI framebuffer with MTRRs
set to uncacheable. This leads to execrable console performance. Once
PMAP is up, remap the framebuffer as write-combining. This reduces
boot time on my laptop by 60% when booting with EFI.
