rmind 67d703cf25 Import of POSIX Asynchronous I/O. 
Seems to be quite stable. Some work still left to do.

Please note, that syscalls are not yet MP-safe, because
of the file and vnode subsystems.

itojun f9121aada7 switch to use strlcpy() from libkern. 2003-05-16 16:28:30 +00:00
atatat b5329c1d85 (1) Don't print the message buffer (via ddb's dmesg command) if the 
message buffer has not yet been set up, mimicking code from the top of
the sysctl routine for retrieving the message buffer.

(2) Add a /l modifier to the trace command.  This makes it print the
backtrace using printf() instead of db_printf(), which has the nice
side-effect of also putting it into the message buffer.  A kernel with
ddb in it but disabled (ie, ddb.onpanic set to zero) will print a
backtrace (which ends up in the message buffer) before dumping (or
not, depending on the value of kern.dump_on_panic) and rebooting, but
if ddb is not disabled, the backtrace is not printed, and there's no
way to get it to display a backtrace such that you can retrieve it
after the dump.  The backtrace printed by gdb is sometimes a little
different.

(3) Documentation for the above.

briggs e2391a87b6 Add a rudimentary 'trap to kgdb' command if KGDB is defined. This allows

jdolecek 9818f641c3 make db_command_table[] const; since there is no way to dynamically extend 
or modify the table at the moment, there is no functionality lost.

jdolecek 8b24036797 Require the machine-dependant DDB commands to be in db_machine_command_table[] 
and link it directly to db_command_table[] so that it's not necessary

g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()
