jonathan 3ac3cbcfb8 Add options DDB_FROMCONSOLE and sysctl ddb.fromconsole, analagous to
DDB_ONPANIC. Lets user ignore breaks but enter DDB on panic.  Intended
for machines where debug on panic is useful, but DDB entry is not,
(public-access console, or terminal-servers which send spurious breaks)

Add new ddb hook, console_debugger(), which decides whether or not to
ignore console ddb requests. Console drivers should be updated to call
console_debugger(), not Debugger(), in response to serial-console
break or ddb keyboard sequence.

thorpej 73aefe65bc If MULTIPROCESSOR, add a spin lock around the kernel printf (in the
appropriate places).  This makes debugging messages work a LOT better
on my multiprocessor Alpha.

ross 3877611a5c Put it back the way it was. 1997-11-17 00:59:56 +00:00
ross 42046e9698 A new kprintf was imported on 10/24, and it will cause a kernel panic
whenever the %: format is used on NetBSD/Alpha. Disable %: for __alpha__.
Note: the "correct" (but untested on other architectures) fix is to
change the wrong: kprintf(cp, oflags, tp, NULL, va_arg(ap, va_list));
    to the right: kprintf(cp, oflags, tp, NULL, ap);

chuck 94fa91f862 import chris torek's vfprintf() from libc [renamed to kprintf and all
floating point stuff removed].

the new kprintf replaces the 3 different (and buggy) versions of
printf that were in the kernel before (kprintf, sprintf, and db_printf),
thus reducing duplicated code by 2/3's.   this fixes (or adds) several
printf formats.  examples:
 %#x   - previously only supported by db_printf [not printf/sprintf]
 %8.8s - printf would print "000chuck" for "chuck" before
 %5p   - printf would print "0x    1" for value 1 before

XXX: new kprintf still supports several non-standard '%' formats that
are supposed to eventually be removed:
  %: - passes an additional format string and argument list recursively
  %b - used to decode error registers
  %r - int, but print in radix "db_radix" [DDB only]
  %z - 'signed hex' [DDB only]
  %n - unsigned int, but print in radix "db_radix" [DDB only]

note that DDB's "%n" conflicts with standard "%n" which takes the
number of characters written so far and stores it into the integer
indicated by the "int *" pointer arg.  yuck!

while here, add comments for each function explaining what it is
supposed to do.

leo d4713d24c2 Implement the kernel part of pr-1891. This allows for a more flexible sized
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

thorpej 6043eb7d80 Avoid running off the end of the format string if the caller botched
the format modifer.  Reported by and suggested fix from Daniel G. Pouzzner
in PR #2633.  Final fix is slightly different now that we support the %q
modifier.  This fix also includes the equivalent fix for sprintf().

thorpej 156e926117 Implement bitmask_snprintf(), which takes a value and a string
representing the names of those bits, prints them into a buffer
provided by the caller, and returns a pointer to that buffer.
Functionality is identical to that of the (non-standard) `%b' printf()
format, which will be deprecated.

Rename the non-exported function ksprintn() to ksnprintn(), and change
it to use a buffer provided by the caller, rather than at static
buffer.

gwr a0d9bd5bb2 The hack-ish tricks to make the ANSI-style va_start macro work in
non-ANSI mode were not quite complete.  This makes non-ANSI work.
Perhaps it would be better to eliminate this hack altogether...

mrg 5abbf990f3 Change reboot(2) to take two arguments: bootopt like normal and also
a boot string for firmware that can do this, such as the SPARC and
the sun3 models.  It is currently silently ignored on all other
hardware now, however.  The MD function "boot()" has been changed to
also take a char *.
