# Initial commands for kdb, alter to suit your needs.
# These commands are executed in kdb_init() context, no SMP, no
# processes. Commands that require process data (including stack or
# registers) are not reliable this early. set and bp commands should
# be safe. Global breakpoint commands affect each cpu as it is booted.
# Standard debugging information for first level support, just type archkdb
# or archkdbcpu or archkdbshort at the kdb prompt.
