c6d139318e For the xenix_ftime() routine, don't use the native version of the struct --
the XENIX version is packed, and two bytes smaller than ours.  So, define
the structure, and have it packed.  I used the __attribte__((packed))
modifier for this; I could also have surrounded the struct definition with
#pragma pack(2) -- but that would have meant making ibcs2_timeb's definition
outside the function.  This may need to be revisited if we ever want to
compile with a compiler other than gcc.  (I also used 'unsigned long'
instead of 'time_t' because I am writing to match an external specification
-- and the definition of time_t could change.)

b3196e4b9f Preliminary support for per-cpu data pages.
This eliminates a lot of #ifdef SMP type code.  Things like _curproc reside
in a data page that is unique on each cpu, eliminating the expensive macros
like:    #define curproc (SMPcurproc[cpunumber()])

There are some unresolved bootstrap and address space sharing issues at
present, but Steve is waiting on this for other work.  There is still some
strictly temporary code present that isn't exactly pretty.

This is part of a larger change that has run into some bumps, this part is
standalone so it should be safe.  The temporary code goes away when the
full idle cpu support is finished.

0231d9ebb6 From the submitted patch :
The kernel with USERCONFIG_BOOT and VISUAL_USERCONFIG option presents
the user the kernel configuration menu upon boot.

The user can navigate the menu with cursor keys. I think it would be
nice if the user can navigate and select a menu item with regular keys
as well, so that the user who is using a serial console which is not
so capable of esc sequences still can choose a menu item.

With the following patch we can select an item by typing an item
number, 1, 2, or 3, or mnemonic `s' to skip UserConfig, 'v' to enter
the visual mode, and `c' to start the CLI mode. `p', `u', `n', and `d'
will move cursor up and down.

124ff4169d The syscons driver doesn't really check the presence of the display
adapter during the system boot. It always assumes there is at least a
monochrome adapter.

This is rather strange assumption. If there is no dispaly adapter, the
console driver cannot be any good...

In this patch, scinit() is split into two parts; the first part is
now called scvidprobe() which will detect the presence of video card
at the CGA or MONO buffer address and returns TRUE if found. It is
called during sccnprobe() and scprobe(). Both will fail if no video
card is found.

The second part, whose name stays the same as before, scinit(), is
called from sccninit() and scattach() to complete initialization of
the found video card.

The keyboard probe code is moved from scprobe() to sckbdprobe();
scprobe() now calls scvidprobe() and sckbdprobe() to carry out device
probe. (This is rather a cosmetic change, but it sure makes the code
look better organized.)

The problem pointed out by Joerg.

ce93f47a1e Don't attempt to generate errors for unpromoted types in va_arg(),
since it is impossible to distinguish unpromoted types from small

related to sizes of args on the stack and not to promotion.

3cbceb8234 correct the wrong ATM option name for native atm access

reported by Bruce Evans.

Bruce also pointed out that NATM is confusing since config(8) defines
NATM as the number of atm pseudo device in "BUILD_DIR/atm.h".
We might change the name in the future but leave it as it is for now.

fec712543d Load the kernel config file where userconfig (with option USERCONFIG_BOOT)
will see it.  The name of the file is obtained by appending ".config"
to the name of the kernel file.  If the file doesn't exist, then an
annoying message is printed.

Reduced the command line buffer size yet again from 4096 to 1024.  It is
oversized to defend against overrun in gets(), but data space is starting
to run out so the buffer size can't be as grossly oversized as before.

e49dd0c779 This should have been committed with the changes to boot.c yesterday.
- Added support for "dual" internal/serial consoles (-D flag).  If -D is set,
  then all i/o from the boot blocks is to and from both the internal console
  and the serial console.  -D has no effect on the kernel (-h decides the
  kernel serial console as usual).  -D should normally be set in /boot.config.
- Get help messages from /boot.help.  You should copy boot.help from the
  biosboot directory to the root directory on the boot drive when you
  install new boot blocks.
- New, less invasive keyboard probe.  Enable keyboard probe dynamically (-P
  flag).  Should probably never be used (use -h instead).
- Fixed/improved initialization from boot.config.  It didn't interact correctly
  with the NAMEBLOCK option, and the initialization of the drive/unit/partition
  didn't stick when a non-default kernel name was entered.
- Don't reset or forget the default drive/unit/... or kernel name so often.
- Set the default kernel name to something unbootable after `?'.
- Display the defaults better.
- Removed PROBE_KEYBOARD_LOCK option (use -h instead).,
- Removed BOOT_FORCE_COMCONSOLE option (use device flag 0x20 instead).
- Removed -a (RB_HALT) flag.  This flag is only used for reboots.

7b3c84247b Preserve %fs and %gs across context switches. This has a relatively low
cost since it is only done in cpu_switch(), not for every exception.
The extra state is kept in the pcb, and handled much like the npx state,
with similar deficiencies (the state is not preserved across signal
handlers, and error handling loses state).

562d05dfae Document a non-standard gdbremote protocol extension (kludge, really)
that I snuck in to our GDB last year.  This allows you to debug headless
machines by sharing the console port between the debugger and the system
console.  It's not 100% reliabile, but it works well.  It's optional
and disabled by default.

2334749d02 If the boot blocks were using the serial port, read the system console
speed using the boot blocks, instead of a hardcoded value stuck in the
kernel.  This way, you can have systems using the same kernel but different
console speeds.

Add a sysctl entry for changing the system console speed.
Lock the user tty speed to match the system console speed.

Nuke CONSPEED.
