231519d15cSJohn Baldwin# comment character.
241519d15cSJohn Baldwin#
251519d15cSJohn Baldwin# To describe a particular object, a block comment (if it exists) should
261519d15cSJohn Baldwin# come first.  Next should come device, options, and hints lines in that
271519d15cSJohn Baldwin# order.  All device and option lines must be described by a comment that
281519d15cSJohn Baldwin# doesn't just expand the device or option name.  Use only a concise
291519d15cSJohn Baldwin# comment on the same line if possible.  Very detailed descriptions of
301519d15cSJohn Baldwin# devices and subsystems belong in man pages.

341519d15cSJohn Baldwin# after an option or device should use one space after the comment character.
351519d15cSJohn Baldwin# To comment out a negative option that disables code and thus should not be

90480c6b8aSGreg Lehey# FreeBSD processes are subject to certain limits to their consumption
91480c6b8aSGreg Lehey# of system resources.  See getrlimit(2) for more details.  Each
92480c6b8aSGreg Lehey# resource limit has two values, a "soft" limit and a "hard" limit.
93480c6b8aSGreg Lehey# The soft limits can be modified during normal system operation, but
94480c6b8aSGreg Lehey# the hard limits are set at boot time.  Their default values are
95480c6b8aSGreg Lehey# in sys/<arch>/include/vmparam.h.  There are two ways to change them:
96480c6b8aSGreg Lehey#
97480c6b8aSGreg Lehey# 1.  Set the values at kernel build time.  The options below are one
98480c6b8aSGreg Lehey#     way to allow that limit to grow to 1GB.  They can be increased
99480c6b8aSGreg Lehey#     further by changing the parameters:

1182e14eb5a1SGarrett Wollman# the devices were probed on the SCSI bus.  This means that if you
