Next should come device, options, and hints lines in that 27194230Sthompsa# order. All device and option lines must be described by a comment that 28194230Sthompsa# doesn't just expand the device or option name.

To be more 294# SMP-friendly, KTRACE uses a worker thread to process most trace events 295# asynchronously to the thread generating the event. This requires a 296# pre-allocated store of objects representing trace events. The 297# KTRACE_REQUEST_POOL option specifies the initial size of this store. 298# The size of the pool can be adjusted both at boottime and runtime via 299# the kern.ktrace_request_pool tunable and sysctl. 300# 301options KTRACE #kernel tracing 302options KTRACE_REQUEST_POOL=101 303 304# 305# KTR is a kernel tracing mechanism imported from BSD/OS. Currently it 306# has no userland interface aside from a few sysctl's. It is enabled with 307# the KTR option. KTR_ENTRIES defines the number of entries in the circular 308# trace buffer. KTR_COMPILE defines the mask of events to compile into the 309# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the 310# initial value of the ktr_mask variable which determines at runtime what 311# events to trace. KTR_CPUMASK determines which CPU's log events, with 312# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events 313# to the console by default. This functionality can be toggled via the 314# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined. 315# 316options KTR 317options KTR_ENTRIES=1024 318options KTR_COMPILE=(KTR_INTR|KTR_PROC) 319options KTR_MASK=KTR_INTR 320options KTR_CPUMASK=0x3 321options KTR_VERBOSE 322 323# 324# The INVARIANTS option is used in a number of source files to enable 325# extra sanity checking of internal structures.

It is a prerequisite for 335# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 336# called. The intent is that you can set 'INVARIANTS' for single 337# source files (by changing the source file or specifying it on the 338# command line) if you have 'INVARIANT_SUPPORT' enabled. Also, if you 339# wish to build a kernel module with 'INVARIANTS', then adding 340# 'INVARIANT_SUPPORT' to your kernel will provide all the necessary 341# infrastructure without the added overhead. 342# 343options INVARIANT_SUPPORT 344 345# 346# The DIAGNOSTIC option is used to enable extra debugging information 347# from some parts of the kernel.
