fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
2003-06-29 22:28:00 +00:00
darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

tsutsui ef47e3f676 Changes to allow machines which don't use text mode at the boot time
to use generic VGA driver(s):
- Allow VGA drivers to use wsfont instead of builtin font.
- Add vga_reset() function, which will be called from MD consinit(),
  to put VGA into text mode. This function is enabled by options VGA_RESET.

tsutsui 89b4d6221e - Replace some magic numbers with proper macro.
- Use vga_6845_{read,write}() defined in pcdisplayvar.h and
  remove vga_crtc_{read,write}() macros in vgareg.h.

junyoung 0f061c7c7a Move vga_common_probe() to vga_common.c. vga_common.c contains common
stuff between existing char-cell VGA driver and raster VGA driver to
come shortly.

junyoung f73c9efaab No need to include opt_vga.h here, since it is included in vgavar.h. 2002-07-07 07:37:50 +00:00

junyoung 472e54071a Rename vc_ccol and vc_crow in struct pcdisplayscreen to cursorcol
and cursorrow, respectively, to be consistent with other members
in the structure.

drochner 3680345a91 simplify console initialization a bit, avoid wasting
memory in attach(), and add some commemts

christos 63a19c881d more cleanups from Julio Merino. 2002-07-01 13:17:48 +00:00
drochner 9b3975fd12 clean up font handling:
-treat the builtin font like any other font at runtime
-for that, copy it to malloc()'d memory during attach()
-in early console initialization, if we have to consider a broken card
 (VGA_CONSOLE_ATI_BROKEN_FONTSEL), copy the builtin font to another
 location in font ram; the attach() code will do the rest
put the "quirk" code into effect again
2002-06-28 22:24:11 +00:00
junyoung a52db40372 Do the necessaries when the builtin font gets saved in slot 1. 2002-06-28 03:38:13 +00:00
junyoung 754342aeb8 - Work around a hardware bug that loaded fonts don't work, which is
found on many (all?) of PCI-based ATI graphics cards. It is fully optional
  and can be enabled by adding `options VGA_CONSOLE_ATI_BROKEN_FONTSEL'
  to config file.
- Temporarily remove `quirk' mechanism. Similar code already exists
  in pci_quirks.c.

christos 71dcc987cd PR/17402: Add wsmoused support by providing get/set char and events. 2002-06-26 23:05:33 +00:00
drochner 6aa49848cf 2 fixes:
-Don't assume fonts to start with character 0, load at the
 right offset. Now we can use eg wsfont/bold8x16.h which
 starts with chr(1).
-Don't touch the hardware if a font is set for a screen which is
 not active.

drochner f9d6718ab9 allow to overwrite the builtin VGA font if necessary,
make the number of available font slots variable,
set up a "quirk" mechanism to tell the generic vga code about crippled
VGA adapters which ignore the "fontsel" TS register,
initiate the quirk table with an ATI chip which happened to be on a board
I tested with.
Afaik quite a number of ATI chips suffers from the "loaded fonts don't
work" problem - these should be added.
Bad side effect of my change: The builtin font will be kicked out
always if a VGA_CONSOLE_SCREENTYPE is specified which needs a loaded
font. In early console initialization, we don't know much about the
graphics card, so we have to assume the worst (ie ATI:-).

hannken 747c45e3e4 Avoid dereferencing null pointer. `data->name == NULL' means default font. 2002-04-04 13:08:35 +00:00
atatat 31144d9976 Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command".  ERESTART is -1, which can lead to
confusion.  ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4.  No ioctl code should now return -1 anywhere.  The
ioctl() system call is now properly restartable.

2001-09-04 15:32:22 +00:00
drochner 09accd52c0 manage fonts through the wsfont framework, which allows to use both
compiled-in or runtime loaded fonts,
keep font pointers in a LRU queue and load into the adapter on demand,
 so we can have more fonts in use than physical font slots

CAUTION: font loading through the wsdisplay device directly into the
adapter doesn't work anymore!

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
2000-09-10 11:44:13 +00:00
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.

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.

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
