+SYNOPSIS
+========
+
+**rtla hwnoise** [*OPTIONS*]
+
+DESCRIPTION
+===========
+
+**rtla hwnoise** collects the periodic summary from the *osnoise* tracer
+running with *interrupts disabled*. By disabling interrupts, and the scheduling
+of threads as a consequence, only non-maskable interrupts and hardware-related
+noise is allowed.
+
+The tool also allows the configurations of the *osnoise* tracer and the
+collection of the tracer output.
+
+OPTIONS
+=======
+.. include:: common_osnoise_options.rst
+
+.. include:: common_top_options.rst
+
+.. include:: common_options.rst
+
+EXAMPLE
+=======
+In the example below, the **rtla hwnoise** tool is set to run on CPUs *1-7*
+on a system with 8 cores/16 threads with hyper-threading enabled.
+
+The tool is set to detect any noise higher than *one microsecond*,
+to run for *ten minutes*, displaying a summary of the report at the
+end of the session::
+
+ # rtla hwnoise -c 1-7 -T 1 -d 10m -q
+ Hardware-related Noise
+ duration: 0 00:10:00 | time is in us
+ CPU Period Runtime Noise % CPU Aval Max Noise Max Single HW NMI
+ 1 #599 599000000 138 99.99997 3 3 4 74
+ 2 #599 599000000 85 99.99998 3 3 4 75
+ 3 #599 599000000 86 99.99998 4 3 6 75
+ 4 #599 599000000 81 99.99998 4 4 2 75
+ 5 #599 599000000 85 99.99998 2 2 2 75
+ 6 #599 599000000 76 99.99998 2 2 0 75
+ 7 #599 599000000 77 99.99998 3 3 0 75
+
+
+The first column shows the *CPU*, and the second column shows how many
+*Periods* the tool ran during the session. The *Runtime* is the time
+the tool effectively runs on the CPU. The *Noise* column is the sum of
+all noise that the tool observed, and the *% CPU Aval* is the relation
+between the *Runtime* and *Noise*.
+
+The *Max Noise* column is the maximum hardware noise the tool detected in a
+single period, and the *Max Single* is the maximum single noise seen.
+
+The *HW* and *NMI* columns show the total number of *hardware* and *NMI* noise
+occurrence observed by the tool.
+
+For example, *CPU 3* ran *599* periods of *1 second Runtime*. The CPU received
+*86 us* of noise during the entire execution, leaving *99.99997 %* of CPU time
+for the application. In the worst single period, the CPU caused *4 us* of
+noise to the application, but it was certainly caused by more than one single
+noise, as the *Max Single* noise was of *3 us*. The CPU has *HW noise,* at a
+rate of *six occurrences*/*ten minutes*. The CPU also has *NMIs*, at a higher
+frequency: around *seven per second*.
+
+The tool should report *0* hardware-related noise in the ideal situation.
+For example, by disabling hyper-threading to remove the hardware noise,
+and disabling the TSC watchdog to remove the NMI (it is possible to identify
+this using tracing options of **rtla hwnoise**), it was possible to reach
+the ideal situation in the same hardware::
+
+ # rtla hwnoise -c 1-7 -T 1 -d 10m -q
+ Hardware-related Noise
+ duration: 0 00:10:00 | time is in us
+ CPU Period Runtime Noise % CPU Aval Max Noise Max Single HW NMI
+ 1 #599 599000000 0 100.00000 0 0 0 0

Subject: [PATCH 5/8] rtla: Add hwnoise tool
The hwnoise tool is a special mode for the osnoise top tool.
hwnoise dispatches the osnoise tracer and displays a summary of the noise.
The difference is that it runs the tracer with the OSNOISE_IRQ_DISABLE
option set, thus only allowing only hardware-related noise, resulting in
a simplified output. hwnoise has the same features of osnoise.
An example of the tool's output:
# rtla hwnoise -c 1-11 -T 1 -d 10m -q
Hardware-related Noise
duration: 0 00:10:00 | time is in us
