3d34bf047b Yet another round of fixes for the VESA support code.
- Express various sizes in bytes, rather than Kbytes, in the video
  mode and adapter information structures.
- Fill 0 in the linear buffer size field if the linear frame buffer
  is not available.
- Remove SW_VESA_USER ioctl. It is still experimetal and was not meant
  to be released.
- Fix missing cast operator.
- Correctly handle pointers returned by the VESA BIOS. The pointers
  may point to the area either in the BIOS ROM or in the buffer supplied
  by the caller.
- Set the destructive cursor at the right moment.

a2aeaf4564 Goodbye BOUNCE_BUFFERS, for a hack it has served us well.
The last consumer of this code (the old SCSI system) has left us and
the CAM code does it's own bouncing.  The isa dma system has been

b326a281a9 Fix and update for VESA BIOS support in syscons.
- Handle pixel (raster text) mode properly.
   - Clear screen and paint border right.
   - Paint text attribute (colors).
   - Fix off-by-one errors.
   - Add some sanity checks.
- Fix some function prototypes.
- Add some comment lines.
- Define generic text mode numbers so that the user can just give
  "80x25", "80x60", "132x25"..., rather than "VGA_xxx", to `vidcontrol'
  to change the current video mode.  `vidoio.c' and `vesa.c' will map
  these numbers to real video mode numbers appropriate and available
  with the given video hardware.  I believe this will be useful to make
  syscons more portable across archtectures.

653c2af6ae Add VESA support to syscons.
Kazu writes:

The VESA support code requires vm86 support. Make sure your kernel
configuration file has the following line.
        options "VM86"
If you want to statically link the VESA support code to the kernel,
add the following option to the kernel configuration file.
        options "VESA"

The vidcontrol command now accepts the following video mode names:
VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600

The VESA_800x600 mode is a raster display mode. The 80x25 text will
be displayed on the 800x600 screen. Useful for some laptop computers.

vidcontrol accepts the new `-i <info>' option, where <info> must be
either `adapter' or `mode'.  When the `-i adapter' option is given,
vidcontrol will print basic information (not much) on the video
adapter. When the `-i mode' option is specified, vidcontrol will
list video modes which are actually supported by the video adapter.

7aadfa5c68 Add a new library function getobjformat(). It checks all the
standard places ("/etc/objformat", ${OBJFORMAT}, argv) for an
indication of the user's preferred object file format.  This
consolidates some code that was starting to be duplicated in more
and more places.

Use the new function in ldconfig.

Note: I don't think that gcc should use getobjformat(), even though
it could.  The compiler should limit itself to functions that are
widespread, to ease porting and cross-compilation.

5b11e2a2f4 Make profiling work for ELF. gprof now autodetects the format of
the executable file, so it will work for both a.out and ELF format
files.  I have split the object format specific code into separate
source files.  It's cleaner than it was before, but it's still
pretty crufty.

Don't cheat on your make world for this update.  A lot of things
have to be rebuilt for it to work, including the compiler and all
of the profiled libraries.

95c3baa7ee Presently there is only one `currentldt' variable for all cpus
in a SMP system. Unexpected things could happen if each cpu
        has a different ldt setting and one cpu tries to use value
        of currentldt set by another cpu.

        The fix is to move currentldt to the per-cpu area. It includes

d1ce81d497 Revamp the ELF include files to better support architecture-independent
applications.  Here's how it works.

The kernel should include <machine/elf.h> to get the definitions
for the native architecture.  It can reference the various ELF
structures with generic names like Elf_Sym, Elf_Shdr, etc.  A define
__ELF_WORD_SIZE is also available with the value 32 or 64 as
appropriate for the native architecture.

Generic applications should include <elf.h>, which is just a wrapper
for <machine/elf.h>.

Applications such as object file dumpers that need to deal with
foreign ELF files can include <sys/elf32.h> and/or <sys/elf64.h>.
Both can be included from the same source file if desired.  The
structure names must be referenced using wordsize-specific names
like Elf32_Sym, Elf64_Shdr, etc.

I haven't change the alpha stuff, but I haven't broken it either.

9fa8a2d794 pmap.c:
Cast pointers to (vm_offset_t) instead of to (u_long) (as before) or to
(uintptr_t)(void *) (as would be more correct).  Don't cast vm_offset_t's
to (u_long) just to do arithmetic on them.

mp_machdep.c:
Cast pointers to (uintptr_t) instead of to (u_long).  Don't forget
to cast pointers to (void *) first or to recover from integral
possible integral promotions, although this is too much work for
machine-dependent code.

vm code generally avoids warnings for pointer vs long size mismatches
by using vm_offset_t to represent pointers; pmap.c often uses plain
`unsigned int' instead of vm_offset_t and didn't use u_long elsewhere,
but this style was messed up by code apparently imported from mp_machdep.c.

506dee0328 1. Reorganized screen saver related code so that both the LKM screen
saver and splash screen can all work properly with syscons.  Note that
the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it
requires additional code from msmith.

- Reorganized the splash screen code to match the latest development
  in this area.
- Delay screen switch in `switch_scr()' until the screen saver is
  stopped, if one is running,
- Start the screen saver immediately, if any, when the `saver' key is
  pressed. (There will be another commit for `kbdcontrol' to support
  this keyword in the keymap file.)
- Do not always stop the screen saver when mouse-related ioctls
  are called.  Stop it only if the mouse is moved or buttons are
  clicked; don't stop it if any other mouse ioctls are called.

2. Added provision to write userland screen savers.  (Contact me if you
are interested in writing one.)

- Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to
  support userland screen savers.

3. Some code clean-ups.

d307f5bacf Don't pretend to support ix86's with 16-bit ints by using longs
just to ensure 32-bit variables.  Doing so broke and/or pessimized
i386's with 64-bit longs (unnecessary use of 64-bit variables
caused remarkably few problems in C code, but the inline asm here
tended to fail because there are no 64-bit registers).  Since the
interfaces here are very machine-dependent and shouldn't be used
outside of the kernel, use a standard types of "known" width instead
of fixed-width types.

Changed all quad_t's to u_int64_t's.  quad_t isn't standard, and
using signed types for 64-bit registers was bogus (but made no
difference).

    The patch supports using the X10 Mouse Remote in both stand-alone and

same serial port, use the mouse for X, and use the remote for other apps
like Fxtv. For instance, we can now control fxtv via the remote control

freeze frame 8)
