* in vga_init(), set the screen type to WSCONS_DEFAULT_TYPE, which defaults
to "80x25".
XXX: the code currently makes no attempt to ensure that a font
with the appropriate width & height is available, effectively
limiting this default to either "80x25" or "80x24" at this
time.
* make wsdisplay_screentype_pick() non static, so that vga_init() can use it
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
FIOASYNC ioctrl command had been forwarded from wsmux to each mouse devices
and the devices had set their own event queue async mode. But no one had took
care of the event queue's mode of wsmux itself. Wsmux should make it's own
event queue async mode when it receive FIOASYNC command.
current attribute, but has all non-color flags turned off. Use this when
doing erasure, as this allows us to optimize repainting in curses.
XXX The way the default attribute is handled is totally bogus and needs to
be fixed.
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
- Wsmouse_input() get new argument 'flag', which indicates whether x/y/z are
relative or absolute.
- Wsmouse get new io controls, WSMOUSEIO_SCALIBCOORDS and
WSMOUSEIO_GCALIBCOORDS.
asynchronously, in the same style like the process attach/detach functions
-intercept the "cnpollc" call which originally went directly to the
keyboard driver and keep track whether the console is in "polling" state
(DDB!)
-pass a NULL callback to the screen switcher and the process attach/detach
functions if the console is "polling", to tell them that asynchronous
completion is forbidden
and one which isn't. The latter is now used for ttyEcfg, enabling the
VT-switching ioctls to work on it. (This allows Linux X servers to work when
/emul/linux/dev/tty0 is linked to /dev/ttyEcfg.)
