ecb56aaf60 Attempt to determine the modes in which 8-bit wide characters are actually
9 wide.

I only need this to improve the mouse cursor, but it has always been
needed to select and/or adjust fonts.

This is complicated because there are no standard parameter tables
giving this bit of information directly, and the device register bit
giving the information can't be trusted even if it is read from the
hardware.  Use a heuristic to guess if the device register can be
trusted.  (The device register is normally read from the BIOS mode
table, but on my system where the device register is wrong, the mode
table doesn't match the hardware and is not used; the device registers
are used in this case.)

7b8306bcd2 When we don't use the parameter table in the BIOS, also don't use most
of our tweaked modes based on it.  In practice, this means limiting the
tweaked modes to at most 80x50 based on 80x25, so there are no 90-column,
80x30 or 80x60 modes.

This happens when the the initial mode is is not in the parameter
table.  We always detected this case, but assumed that the (necessarily
nonstandard) parameters of the initial mode could be tweaked just as
blindly as the probably-standard parameters of initial modes in the
table.

On 1 laptop system with near-VGA where the initial mode is nonstandard,
this is because the hardware apparently doesn't support 9-bit mode,
but otherwise has standard timing.  The initial mode has 8-bit mode
CRTC horizontal parameters similar to those in syscons' 90-column modes
and in EGA modes.  Tweaking these values for the 90-column modes has
little effect except to print the extra 10 columns off the screen.
Tweaking from 80x25 to 80x30 requires changing from 400 scan lines to
480.  This can probably be made to work, but syscons blindly applies
values based on standard timing.  This gives blank output.  Tweaking
from 80x25 to 80x50 doesn't change the CRTC timing and works.

89a1e6c3eb Fix 3 entries in mode tables related to mono and 90-column text modes.
Newer VGAs don't support any mono modes, but bugs in the tables created
2 virtual mono modes (#45 90x43 and #112 80x43) that behaved more
strangely than crashing.  90-column modes are tweaked 80-column ones
and also fail to work on newer VGAs.  #45 did crash (hang) on some
hardware.

cfd7bacef2 Update d_mmap() to accept vm_ooffset_t and vm_memattr_t.
This replaces d_mmap() with the d_mmap2() implementation and also
changes the type of offset to vm_ooffset_t.

Purge d_mmap2().

All driver modules will need to be rebuilt since D_VERSION is also
bumped.

9336e0699b Replace explicit calls to video methods with their respective variants
implemented with macros. This patch improves code readability. Reasoning
behind vidd_* is a sort of "video discipline".

List of macros is supposed to be complete--all methods of video_switch
ought to have their respective macros from now on.

Functionally, this code should be no-op. My intention is to leave current
behaviour of touched code as is.

b7c96c0d0b Add a font width argument to vi_load_font_t, vi_save_font_t and vi_putm_t
and do some preparations for handling 12x22 fonts (currently lots of code
implies and/or hardcodes a font width of 8 pixels). This will be required
on sparc64 which uses a default font size of 12x22 in order to add font
loading and saving support as well as to use a syscons(4)-supplied mouse
pointer image.
This API breakage is committed now so it can be MFC'ed in time for 6.0
and later on upcoming framebuffer drivers destined for use on sparc64
and which are expected to rely on using font loading internally and on
a syscons(4)-supplied mouse pointer image can be easily MFC'ed to
RELENG_6 rather than requiring a backport.

2169193596 Converge towards i386. I originally resisted creating <machine/pc/bios.h>
because it was mostly irrelevant - except for the silly BIOS_PADDRTOVADDR
etc macros.  Along the way of working around this, I missed a few things.

* Make syscons properly inherit the bios capslock/shiftlock/etc state like
  i386 does.  Note that we cannot inherit the bios key repeat rate because
  that requires a bios call (which is impossible for us).
* Give syscons the ability to beep on amd64.  Oops.

While here, make bios.c compile and add it to files.amd64.

ae3c9aff52 Unbreak alpha and ia64 builds. The previous change made the inclusion
of <machine/pc/bios.h> specific to i386 and added a conditional define
for BIOS_PADDRTOVADDR that depends on ISA_HOLE_START. The latter is
undefined on alpha and ia64. Since the former is defined the same on
both alpha and ia64, assume the ISA_HOLE_START dependent definition
is specific to amd64 and use the identity-mapping in all other cases.

This of course is getting uglier every day...

227f9a1c58 - Add vm_paddr_t, a physical address type. This is required for systems
where physical addresses larger than virtual addresses, such as i386s
  with PAE.
- Use this to represent physical addresses in the MI vm system and in the
  i386 pmap code.  This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
  detection code, and due to kvtop returning vm_paddr_t instead of u_long.

Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

07159f9c56 Cleanup of the d_mmap_t interface.
- Get rid of the useless atop() / pmap_phys_address() detour.  The
  device mmap handlers must now give back the physical address
  without atop()'ing it.
- Don't borrow the physical address of the mapping in the returned
  int.  Now we properly pass a vm_offset_t * and expect it to be
  filled by the mmap handler when the mapping was successful.  The
  mmap handler must now return 0 when successful, any other value
  is considered as an error.  Previously, returning -1 was the only
  way to fail.  This change thus accidentally fixes some devices
  which were bogusly returning errno constants which would have been
  considered as addresses by the device pager.
- Garbage collect the poorly named pmap_phys_address() now that it's
  no longer used.
- Convert all the d_mmap_t consumers to the new API.

I'm still not sure wheter we need a __FreeBSD_version bump for this,
since and we didn't guarantee API/ABI stability until 5.1-RELEASE.
