69c9583604 Make the prompt look like on OpenBoot. 1999-11-27 21:44:47 +00:00

3206c41a3c Changes the default prompt to "ok".
Mike says the whole idea of a current device was a bad idea in first place,
and will be doing away with currdev.

Anyway, people are not supposed to even notice this. :-)

346f1ca8fc Don't clobber the "prompt" variable if it has already been set (e. g.
from within loader.conf).

08c9325cb2 Fix a number of memory leaks and other memory-related disorders.
Also, unbreak the breakage introduced at the last revision of module.c.
This changes the semantics of mod_searchfile() (and mod_searchmodule())
to make the caller's responsibility freeing the buffer returned. This
is different from other functions in loader's code, and was done as a
fix for kern/9631. If someone wants to revert this to the original
behavior, don't forget to fix kern/9631 in another way.

This should also fix bin/10462, which was introduced as a result of the
first try at kern/9631 (module.c last revision).

47749087ac Make use of prototypes to silence warnings.
Change include() so it will be able to load files with forth code,
instead of just builtins. Remove #@- from the include section of the
help file, since they don't work in the new version of include, unless
BOOT_FORTH is not defined.

Change bf_run() so it will return the result returned by ficlExec(). Also,
make bf_run() push "interpret" to be executed by ficlExec(), since ficlExec()
doesn't do it by itself. (Things worked previously because nothing
recursed through ficlExec() by the way of bf_run()).

Change/extend comments on builtin behavior.

Search for "interpret" at the end of bf_init(), so /boot/boot.4th can
provide it's own version.

Remove dead code.

interp.c
	Rename the 'source' command to 'include' in order to avoid conflict
	with the ANS Forth command of the same name. (kern/9473)

interp_forth.c:
	Changes from kern/9412 (EXCEPTION word), kern/9442 (TIB buffer
	sizing) and an improved version of kern/9460 (set
	version numbers).

load_aout.c:
	Trim some obsolete #if 0'ed cruft.

pnp.c:
	Tidy the pnpscan output, turn off the module scanning until we
	sort out how to do it right.

c7db92c026 Add BootForth hooks; if BOOT_FORTH is defined, pass every line read
to the Forth interpreter.  Instantiate all of our inbuilt commands
as Forth words, and handle them being called from there.

Add my copyright to the bcache module (oops).

eddbe21def Make ISA PnP work. This successfully enumerates as many ISA devices as I
can fit into my test machine.

 - Move to using STAILQs rather than ad-hoc singly-linked lists.
 - Use a mostly procedural interface to the PnP information.  This
   improves data-hiding.

Implement a new linker-set technique (currently on i386 only but should work
on Alpha as well).  This is a good candidate for replacing the current
gensetdefs cruft completely.

Remove debugging in command_read().
Correctly strip leading controls on script commands.
Make 'ls' more DWIM in regard to pathnames.  We can still do better.

b820c8e626 - VERBOSE_LS is obsolete, as the heap is much better behaved now.
- Don't whine about nodes we can't stat(); these are usually
   symlinks that lead out of the filesystem.
 - Autoboot is now controlled by $autoboot_delay, which is a value
   in seconds or NO to disable autoboot.
 - Don't autoboot at the end of boot.conf if we have already tried.
 - Add a 'read' command to complement 'echo'.  Both are still hidden.
 - Improve the 'source' command/function so that it is possible to
   source scripts off removable media.  The entire script is read and
   saved before beginning execution.  Script lines beginning with
   '@' will not be echoed when being executed.  Script execution will
   normally terminate at the first error, however if the script line
   begins with '-' this behaviour is overriden for that command.

0d5d0b20dc Resynch with working sources before BTX integration.
- Use format-independant module allocator.
 - Conditionalise ISA PnP support.
 - Simplify PnP enumerator interface.
 - Improve module/object searching.
 - Add missing depend/install targets in BTX makefiles.
 - Pass the kernel environment and module data in extended bootinfo fields.
 - Add a pointer to the end of the kernel + modules in bootinfo.
 - Fix parsing of old-style kernel arguments.

06b57b0e09 Bootstrap updates.
- Move some startup code from MD to MI sections
 - Add a 'copyout' and some copyout-related functions.  These will be
   obsoleted when BTX is available for the 386 and the kernel load
   area becomes directly addressable.
 - Add the ability load an arbitrary file as a module, associating
   and arbitrary type string with it.  This can be used eg. for loading
   splash-screen images etc.
 - Add KLD module dependancy infrastructure.  We know how to look for
   dependancies inside KLD modules, how to resolve these dependancies
   and what to do if things go wrong.  Only works for a.out at the
   moment, due to lack of an MI ELF loader.  Attach KLD module information
   to loaded modules as metadata, but don't pass it to the kernel (it
   can find it itself).
 - Load a.out KLD modules on a page boundary.  Only pad the a.out BSS
   for the kernel, as it may want to throw symbols away.  (We might want
   to do this for KLD modules too.)
 - Allow commands to be hidden from the '?' display, to avoid cluttering
   it with things like 'echo'.  Add 'echo'.
 - Bring the 'prompt' command into line with the parser syntax.
 - Fix the verbose 'ls'; it was using an uninitialised stack variable.
 - Add a '-v' flag to 'lsmod' to have it display module metadata as well
   (not terribly useful for the average user)
 - Support a 'module searchpath' for required modules.
 - The bootstrap file on i386 is now called 'loader' to permit the
   /boot directory to use that name.
 - Discard the old i386 pread() function, as it's replaced by
   arch_readin()

c2f9d95de5 This is the new unified bootstrap, sometimes known previously as the
'three-stage' bootstrap.
There are a number of caveats with the code in its current state:
 - The i386 bootstrap only supports booting from a floppy.
 - The kernel and kld do not yet know how to deal with the extended
   information and module summary passed in.
 - PnP-based autodetection and demand loading of modules is not implemented.
 - i386 ELF kernel loading is not ready yet.
 - The i386 bootstrap is loaded via an ugly blockmap.

On the alpha, both net- and disk-booting (SRM console machines only) is
supported.  No blockmaps are used by this code.
