drochner a960881851 -make the default screentype override less invasive, call it
VGA_CONSOLE_SCREENTYPE because the screen types are hardware specific
 and make it affect the console only (no need to change runtime
 behaviour), don't call vga_setscreentype() unless necessary (to avoid
 trouble with strange hardware - PR kern/11025)
-some beginnings of ISO-7 (greek) font support

lukem 6439b28202 * rename vga_stdscreen* -> vga_25lscreen*
* 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

thorpej f80d70f19a Just add the mmap argument to vga_common_attach(), don't bother
with vga_extended_attach().

simonb 889c658b5b Change the kernel mmap interface so that the offset to map is an
"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.

soda 849b74a926 add vga_extended_attach function on arc port, to make mmap() available.
XXX - is it better to remove "#ifdef arc"?

cgd d8dcb11d4f don't include ISA headers. these have been properly abstracted so that
the ISA headers are unnecessary, and they're used by PCI VGA.  There may
not be any ISA at all.

thorpej fc96443d15 New callout mechanism with two major improvements over the old
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.

ad ea0751f1aa Finish with fixing the SOFTCURSOR stuff. 2000-01-25 02:44:03 +00:00
ad e75404417a Add and use pcdisplay_cursor_init(). Still a couple of nits with this, I
will resolve when I can test properly.

drochner 106e6868db fix off-by-one error in font table initialisation
(mostly harmless because it is zero initialized in most cases anyway)

drochner 162086b1cd do the screen switch asynchronously (via timeout(0)) if possible,
this hopefully helps for the (very rare) display corruption reported
in PR kern/8628

ad f96e055d70 - mc6845's cursor is disabled by punching bit 6 of cursor start register.
- Add new option (PCDISPLAY_SOFTCURSOR) that provides a large, non-blinking
  cursor in software.

drochner 00a4d0521a use defopted WSCONS_SUPPORT_PCVTFONTS, refuse to load pcvt fonts if this
option is not given, suppress complaints in non-debug case

drochner b2c812d776 set "fontset" variables to 0 if no appropriate font was found for a
freshly allocated screen, should fix panic if "vga_mapchar()" it
attempted later

as intended

drochner dbdaf91650 change the "mapchar" interface to return a "quality" or "match level"
arguments which allows to find approximations for characters which are
not present in a font

drochner 23cfea8327 -implement new wscons font handling with separate download and selection
calls
-support use of 2 fonts simultanously; this costs the ability to
"highlight", ie to use the upper 8 colours
-define screen types "80x25bf" and "80x50bf" which use this ability
-add conditional code to deal with the weird mapping of pcvt's
supplemental fonts
1999-01-13 16:48:58 +00:00
drochner 98e630dbe0 Allow to deallocate also the currently visible virtual screen (unless
it is the console).
This requires vva_show_screen() to catch the case where it has no screen
to switch from, ie no need to save the current state.

augustss 44df4dcc85 Add a wscons display type `unknown' that the generic VGA driver can
return until someone fixes it for real.

drochner 3d545acb51 Overload the generic "copyrows" function by a private one which implents
a "fast scroll" by setting the display start in memory.
(Only implemented for "scroll up" because this is more used. "scroll down"
is easy to add.)
This moves the semantics of "copyrows" to something like "moverows";
the contents of the new visible lines at the bottom is undefined.
The emulations can live without the original "copy" semantics.

drochner b84dbbb37c Put definitions and subroutines needed for all PC display adapters
(MGA/GCA and compatibles) into global headers / source files.
Let the VGA driver use them.

drochner 95bdb660ed Simple screen attribute handling for wscons.
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.
