83#### Debugging options
84
85## The DDB in-kernel debugger runs at panic (unless DDB_ONPANIC=0), or at
86## serial console break or keyboard reset, where the PROM would normally
87## intercept.  DDB_HISTORY_SIZE adds up/down arrow command history.
88#options 	DDB			# kernel dynamic debugger
89#options 	DDB_HISTORY_SIZE=100	# enable history editing in DDB
90#options 	DDB_ONPANIC=1		# see also sysctl(7): `ddb.onpanic'
91
92## You may also use gdb, on another computer connected to this machine over
93## a serial port.  Both KGDB_DEV and KGDB_DEVRATE should be specified;
94## KGDB_DEV is a dev_t encoded device number of the serial port to use.
95## (0xc01 = ttya, 0xc02 = ttyb.)
96#options 	KGDB			# support for kernel gdb
97#options 	KGDB_DEV=0xc01		# kgdb device number (this is `ttyb')

108## cause the kernel to panic if corruption of internal data structures
109## is detected.

121## `INSECURE' turns off the kernel security level (securelevel = 0 always).
122## This allows writing to /dev/mem, loading kernel modules while multi-user,
123## and other insecurities good only for development work.  Do not use this
124## option on a production machine.
125options 	INSECURE
126
127## `FDSCRIPTS' allows non-readable but executable scripts by providing a
128## pre-opened opaque file to the script interpreter.  `SETUIDSCRIPTS',
129## which implies FDSCRIPTS, allows scripts to be set-user-id using the same

322## Valid flags are:

325##	0x02		Use DMA completion interrupts
326##	0x04		Allow disconnect/reselect
