Chernov 3396a8d6623SGarrett Wollman# 340c508c1b6SJohn Baldwin# KTR is a kernel tracing mechanism imported from BSD/OS. Currently it 341c508c1b6SJohn Baldwin# has no userland interface aside from a few sysctl's. It is enabled with 3420f8870a2SJohn Baldwin# the KTR option. KTR_ENTRIES defines the number of entries in the circular 3430f8870a2SJohn Baldwin# trace buffer. KTR_COMPILE defines the mask of events to compile into the 3440f8870a2SJohn Baldwin# kernel as defined by the KTR_* constants in <sys/ktr.h>. KTR_MASK defines the 345c508c1b6SJohn Baldwin# initial value of the ktr_mask variable which determines at runtime what 346c508c1b6SJohn Baldwin# events to trace. KTR_CPUMASK determines which CPU's log events, with 347d902baa4SJohn Baldwin# bit X corresponding to cpu X. KTR_VERBOSE enables dumping of KTR events 348d902baa4SJohn Baldwin# to the console by default. This functionality can be toggled via the 349d902baa4SJohn Baldwin# debug.ktr_verbose sysctl and defaults to off if KTR_VERBOSE is not defined. 350c508c1b6SJohn Baldwin# 351c508c1b6SJohn Baldwinoptions KTR 352c508c1b6SJohn Baldwinoptions KTR_ENTRIES=1024 35325388b6cSBruce Evansoptions KTR_COMPILE=(KTR_INTR|KTR_PROC) 354a9672a81SJohn Baldwinoptions KTR_MASK=KTR_INTR 355c508c1b6SJohn Baldwinoptions KTR_CPUMASK=0x3 356d902baa4SJohn Baldwinoptions KTR_VERBOSE 357c508c1b6SJohn Baldwin 358c508c1b6SJohn Baldwin# 359453ffeefSRobert Watson# ALQ(9) is a facilty for the asynchronous queuing of records from the kernel 360453ffeefSRobert Watson# to a vnode, and is employed by services such as KTR(4) to produce trace 361453ffeefSRobert Watson# files based on a kernel event stream.
