To be more 293# SMP-friendly, KTRACE uses a worker thread to process most trace events 294# asynchronously to the thread generating the event. This requires a 295# pre-allocated store of objects representing trace events. The 296# KTRACE_REQUEST_POOL option specifies the initial size of this store. 297# The size of the pool can be adjusted both at boottime and runtime via 298# the kern.ktrace_request_pool tunable and sysctl. 299# 300options KTRACE #kernel tracing 301options KTRACE_REQUEST_POOL=101 302 303# 304# KTR is a kernel tracing mechanism imported from BSD/OS. Currently it 305# has no userland interface aside from a few sysctl's. It is enabled with 306# the KTR option. KTR_ENTRIES defines the number of entries in the circular 307# trace buffer. KTR_COMPILE defines the mask of events to compile into the 308# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the 309# initial value of the ktr_mask variable which determines at runtime what 310# events to trace. KTR_CPUMASK determines which CPU's log events, with 311# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events 312# to the console by default. This functionality can be toggled via the 313# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined. 314# 315options KTR 316options KTR_ENTRIES=1024 317options KTR_COMPILE=(KTR_INTR|KTR_PROC) 318options KTR_MASK=KTR_INTR 319options KTR_CPUMASK=0x3 320options KTR_VERBOSE 321 322# 323# The INVARIANTS option is used in a number of source files to enable 324# extra sanity checking of internal structures.

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