+config LTT
+	bool "Linux Trace Toolkit Instrumentation Support"
+	depends on EXPERIMENTAL
+	select LTT_HEARTBEAT if MIPS
+	select LTT_SYNTHETIC_TSC if MIPS
+	default n
+	help
+	  It is possible for the kernel to log important events to a trace
+	  facility. Doing so, enables the use of the generated traces in order
+	  to reconstruct the dynamic behavior of the kernel, and hence the
+	  whole system.
+
+	  The tracing process contains 4 parts :
+	      1) The logging of events by key parts of the kernel.
+	      2) The tracer that keeps the events in a data buffer (uses
+	         relayfs).
+	      3) A trace daemon that interacts with the tracer and is
+	         notified every time there is a certain quantity of data to
+	         read from the tracer.
+	      4) A trace event data decoder that reads the accumulated data
+	         and formats it in a human-readable format.
+
+	  If you say Y, the first component will be built into the kernel.
+
+	  For more information on kernel tracing, the trace daemon or the event
+	  decoder, please check the following address :
+	       http://www.opersys.com/ltt
+	  See also the experimental page of the project :
+	       http://ltt.polymtl.ca
+
+config LTT_TRACER
+	tristate "Linux Trace Toolkit Tracer"
+	depends on LTT
+	default y
+	help
+	  If you enable this option, the Linux Trace Toolkit Tracer will be
+	  either built in the kernel or as module.
+
+	  Critical parts of the kernel will call upon the kernel tracing
+	  function. The data is then recorded by the tracer if a trace daemon
+	  is running in user-space and has issued a "start" command.
+
+	  For more information on kernel tracing, the trace daemon or the event
+	  decoder, please check the following address :
+	       http://www.opersys.com/ltt
+	  See also the experimental page of the project :
+	       http://ltt.polymtl.ca

+config LTT_RELAY
+	tristate "Linux Trace Toolkit Relay+DebugFS Support"
+	select RELAY
+	select DEBUG_FS
+	depends on LTT
+	depends on LTT_TRACER
+	default y
+	help
+	  Support using relay and debugfs to log the data obtained through LTT.
+
+	  If you don't have special hardware, you almost certainly want
+	  to say Y here.
+
+config LTT_ALIGNMENT
+	bool "Align Linux Trace Toolkit Traces"
+	depends on LTT
+	default y
+	help
+	  This option enables dynamic alignment of data in buffers. The
+	  alignment is made on the smallest size between architecture size
+	  and the size of the value to be written.
+
+	  Dynamically calculating the offset of the data has a performance cost,
+	  but it is more efficient on some architectures (especially 64 bits) to
+	  align data than to write it unaligned.
+
+config LTT_HEARTBEAT
+	bool "Activate Linux Trace Toolkit Heartbeat Timer"
+	depends on LTT
+	default n
+	help
+	  The Linux Trace Toolkit Heartbeat Timer fires at an interval small
+	  enough to guarantee that the 32 bits truncated TSC won't overflow
+	  between two timer execution.
+
+config LTT_HEARTBEAT_EVENT
+	bool "Write heartbeat event to shrink traces"
+	depends on LTT_HEARTBEAT
+	default y
+	help
+	  This option makes the heartbeat timer write an event in each tracefile
+	  at an interval that is one tenth of the time it takes to overflow 32
+	  bits at your CPU frequency.
+
+	  If this option is not enabled, 64 bits fields must be used in each
+	  event header to save the full TSC : it can make traces about 1/10
+	  bigger. It is suggested that you enable this option to make more
+	  compact traces.
+
+config LTT_SYNTHETIC_TSC
+	bool "Keep a synthetic cpu timestamp counter"
+	depends on LTT_HEARTBEAT
+	default n
+	help
+	  This option is only useful on archtecture lacking a 64 bits timestamp
+	  counter : it generates a "synthetic" 64 bits timestamp by updating
+	  the 32 MSB at each heartbeat atomically. See kernel/ltt-heartbeat.c
+	  for details.
+
+config LTT_USERSPACE_GENERIC
+	bool "Allow tracing from userspace"
+	depends on LTT_TRACER
+	default y
+	help
+	  This options allows processes to trace through the ltt_trace_generic
+	  system call after they have registered their facilities with
+	  ltt_register_generic.
+
+config LTT_NETLINK_CONTROL
+	tristate "Linux Trace Toolkit Netlink Controller"
+	depends on LTT_TRACER
+	default m
+	help
+	  If you enable this option, the Linux Trace Toolkit Netlink Controller
+	  will be either built in the kernel of as module.
