-APK Workloads
-=============
-
-APK resolution
---------------
-
-WA has various resource getters that can be configured to locate APK files but for most people APK files
-should be kept in the ``$WA_HOME/dependencies/SOME_WORKLOAD/`` directory. (by default 
-``~/.workload_automation/dependencies/SOME_WORKLOAD/``). The ``WA_HOME`` enviroment variable can be used
-to chnage the location of this folder. The APK files need to be put into the corresponding directories
-for the workload they belong to. The name of the file can be anything but as explained below may need
-to contain certain peices of information.
-
-All ApkWorkloads have parameters that affect the way in which APK files are resolved, ``exact_abi``,
-``force_install`` and ``check_apk``. Their exact behaviours are outlined below.
-
-.. confval:: exact_abi
-
-   If this setting is enabled WA's resource resolvers will look for the devices ABI with any native 
-   code present in the apk. By default this setting is disabled since most apks will work across all
-   devices. You may wish to enable this feature when working with devices that support multiple ABI's (like 
-   64-bit devices that can run 32-bit APK files) and are specifically trying to test one or the other.
-
-.. confval:: force_install
-
-   If this setting is enabled WA will *always* use the APK file on the host, and re-install it on every
-   iteration. If there is no APK on the host that is a suitable version and/or ABI for the workload WA
-   will error when ``force_install`` is enabled.
-
-.. confval:: check_apk
-
-   This parameter is used to specify a preference over host or target versions of the app. When set to
-   ``True`` WA will prefer the host side version of the APK. It will check if the host has the APK and
-   if the host APK meets the version requirements of the workload. If does and the target already has
-   same version nothing will be done, other wise it will overwrite the targets app with the host version.
-   If the hosts is missing the APK or it does not meet version requirements WA will fall back to the app
-   on the target if it has the app and it is of a suitable version. When this parameter is set to 
-   ``false`` WA will prefer to use the version already on the target if it meets the workloads version
-   requirements. If it does not it will fall back to search the host for the correct version. In both modes
-   if neither the host nor target have a suitable version, WA will error and not run the workload.
-
-Some workloads will also feature the follow parameters which will alter the way their APK files are resolved.
-
-.. confval:: version
-
-   This parameter is used to specify which version of uiautomation for the workload is used. In some workloads
-   e.g. ``geekbench`` multiple versions with drastically different UI's are supported. When a workload uses a
-   version it is required for the APK file to contain the uiautomation version in the file name. In the case
-   of antutu the file names could be: ``geekbench_2.apk`` or ``geekbench_3.apk``.
-
-.. confval:: variant_name
-
-   Some workloads use variants of APK files, this is usually the case with web browser APK files, these work
-   in exactly the same way as the version,  the variant of the apk

 Recording
 ---------
 
-WA features a ``record`` command that will automatically deploy and start
-revent on the target device::
+To record, transfer the revent binary to the device, then invoke ``revent
+record``, giving it the time (in seconds) you want to record for, and the
+file you want to record to (WA expects these files to have .revent
+extension)::
 
-    wa record

-    [Pressed Enter]
-    INFO     Press Enter when you have finished recording...
-    [Pressed Enter]
-    INFO     Pulling files from device
-
-Once started, you will need to get the target device ready to record (e.g.
-unlock screen, navigate menus and launch an app) then press ``ENTER``.
-The recording has now started and button presses, taps, etc you perform on
-the device will go into the .revent file. To stop the recording simply press
-``ENTER`` again.
-
-Once you have finished recording the revent file will be pulled from the device
-to the current directory. It will be named ``{device_model}.revent``. When
-recording revent files for a ``GameWorkload`` you can use the ``-s`` option to
-add ``run`` or ``setup`` suffixes.
-
-From version 2.6 of WA onwards, a "gamepad" recording mode is also supported.
-This mode requires a gamepad to be connected to the device when recoridng, but
-the recordings produced in this mode should be portable across devices.
-
-For more information run please read :ref:`record-command`

 Using revent With Workloads
@@ -114,359 +100,3 @@ where as UI Automator only works for Android UI elements (such as text boxes or
 radio buttons), which makes the latter useless for things like games. Recording
 revent sequence is also faster than writing automation code (on the other hand,
 one would need maintain a different revent log for each screen resolution).
-
-
-Using state detection with revent
-=================================
-
-State detection can be used to verify that a workload is executing as expected.
-This utility, if enabled, and if state definitions are available for the
-particular workload, takes a screenshot after the setup and the run revent
-sequence, matches the screenshot to a state and compares with the expected
-state. A WorkloadError is raised if an unexpected state is encountered.
-
-To enable state detection, make sure a valid state definition file and
-templates exist for your workload and set the check_states parameter to True.
-
-State definition directory
---------------------------
-
-State and phase definitions should be placed in a directory of the following
-structure inside the dependencies directory of each workload (along with
-revent files etc):
-
-::
-
-   dependencies/
-      <workload_name>/
-         state_definitions/
-            definition.yaml
-            templates/
-               <oneTemplate>.png
-               <anotherTemplate>.png
-               ...
-
-definition.yaml file
---------------------
-
-This defines each state of the workload and lists which templates are expected
-to be found and how many are required to be detected for a conclusive match. It
-also defines the expected state in each workload phase where a state detection
-is run (currently those are setup_complete and run_complete).
-
-Templates are picture elements to be matched in a screenshot. Each template
-mentioned in the definition file should be placed as a file with the same name
-and a .png extension inside the templates folder. Creating template png files
-is as simple as taking a screenshot of the workload in a given state, cropping
-out the relevant templates (eg. a button, label or other unique element that is
-present in that state) and storing them in PNG format.
-
-Please see the definition file for Angry Birds below as an example to
-understand the format. Note that more than just two states (for the afterSetup
-and afterRun phase) can be defined and this helps track the cause of errors in
-case an unexpected state is encountered.

-File format of revent recordings
-================================
-
-You do not need to understand recording format in order to use revent. This
-section is intended for those looking to extend revent in some way, or to
-utilize revent recordings for other purposes.
-
-Format Overview
----------------
-
-Recordings are stored in a binary format. A recording consists of three
-sections::
-
-    +-+-+-+-+-+-+-+-+-+-+-+
-    |       Header        |
-    +-+-+-+-+-+-+-+-+-+-+-+
-    |                     |
-    |  Device Description |
-    |                     |
-    +-+-+-+-+-+-+-+-+-+-+-+
-    |                     |
-    |                     |
-    |     Event Stream    |
-    |                     |
-    |                     |
-    +-+-+-+-+-+-+-+-+-+-+-+
-
-The header contains metadata describing the recording. The device description
-contains information about input devices involved in this recording. Finally,
-the event stream contains the recorded input events.
-
-All fields are either fixed size or prefixed with their length or the number of
-(fixed-sized) elements.
-
-.. note:: All values below are little endian
-
-
-Recording Header
-----------------
-
-An revent recoding header has the following structure
-
- * It starts with the "magic" string ``REVENT`` to indicate that this is an
-   revent recording.
- * The magic is followed by a 16 bit version number. This indicates the format
-   version of the recording that follows. Current version is ``2``.
- * The next 16 bits indicate the type of the recording. This dictates the
-   structure of the Device Description section. Valid values are:
-

-gamepad recording
-~~~~~~~~~~~~~~~~~
-
-The recording has been made from a specific gamepad. All events in the stream
-will be for that device only. The section describes the device properties that
-will be used to create a virtual input device using ``/dev/uinput``. Please
-see ``linux/input.h`` header in the Linux kernel source for more information
-about the fields in this section.

-Event structure
----------------
-
-The majority of an revent recording will be made up of the input events that were
-recorded. The event stream is prefixed with the number of events in the stream.
-
-Each event entry structured as follows:
-
- * An unsigned integer representing which device from the list of device paths
-   this event is for (zero indexed). E.g. Device ID = 3 would be the 4th
-   device in the list of device paths.
- * A signed integer representing the number of seconds since "epoch" when the
-   event was recorded.
- * A signed integer representing the microseconds part of the timestamp.
- * An unsigned integer representing the event type
- * An unsigned integer representing the event code
- * An unsigned integer representing the event value
-
-For more information about the event type, code and value please read:
-https://www.kernel.org/doc/Documentation/input/event-codes.txt

-------
-
-WA has a parser for revent recordings. This can be used to work with revent
-recordings in scripts. Here is an example:
-
-.. code:: python
-
-    from wlauto.utils.revent import ReventRecording
-
-    with ReventRecording('/path/to/recording.revent') as recording:
-        print "Recording: {}".format(recording.filepath)
-        print "There are {} input events".format(recording.num_events)
-        print "Over a total of {} seconds".format(recording.duration)

-
-    revent supports an alternative recording mode, where it will record events

-    a recording, revent will first create a virtual gamepad using the
-    description, and will replay the events into it, so a physical controller
-    does not need to be connected on replay. Unlike standard revent recordings,
-    recordings generated in this mode should be (to an extent) portable across
-    different devices.
-
-    note:
-
-      - The device on which a recording is being made in gamepad mode, must have
-        exactly one gamepad connected to it.
-      - The device on which a gamepad recording is being replayed must have
-        /dev/uinput enabled in the kernel (this interface is necessary to create

-    """
-    Implements gem5 Android device.
-
-    This class allows a user to connect WA to a simulation using gem5. The
-    connection to the device is made using the telnet connection of the
-    simulator, and is used for all commands. The simulator does not have ADB
-    support, and therefore we need to fall back to using standard shell
-    commands.
-
-    Files are copied into the simulation using a VirtIO 9P device in gem5. Files
-    are copied out of the simulated environment using the m5 writefile command
-    within the simulated system.
-
-    When starting the workload run, the simulator is automatically started by
-    Workload Automation, and a connection to the simulator is established. WA
-    will then wait for Android to boot on the simulated system (which can take
-    hours), prior to executing any other commands on the device. It is also
-    possible to resume from a checkpoint when starting the simulation. To do
-    this, please append the relevant checkpoint commands from the gem5
-    simulation script to the gem5_discription argument in the agenda.
-
-    Host system requirements:
-        * VirtIO support. We rely on diod on the host system. This can be
-          installed on ubuntu using the following command:
-
-                sudo apt-get install diod
-
-    Guest requirements:
-        * VirtIO support. We rely on VirtIO to move files into the simulation.
-          Please make sure that the following are set in the kernel
-          configuration:
-
-                CONFIG_NET_9P=y

-
-                CONFIG_VIRTIO_BLK=y
-
-        * m5 binary. Please make sure that the m5 binary is on the device and
-          can by found in the path.

-    TC2 is a development board, which has three A7 cores and two A15 cores.
-
-    TC2 has a number of boot parameters which are:
-
-        :root_mount: Defaults to '/media/VEMSD'
-        :boot_firmware: It has only two boot firmware options, which are
-                        uefi and bootmon. Defaults to 'uefi'.
-        :fs_medium: Defaults to 'usb'.
-        :device_working_directory: The direcitory that WA will be using to copy
-                                   files to. Defaults to 'data/local/usecase'
-        :serial_device: The serial device which TC2 is connected to. Defaults to
-                        '/dev/ttyS0'.
-        :serial_baud: Defaults to 38400.
-        :serial_max_timeout: Serial timeout value in seconds. Defaults to 600.
-        :serial_log: Defaults to standard output.
-        :init_timeout: The timeout in seconds to init the device. Defaults set
-                       to 30.
-        :always_delete_uefi_entry: If true, it will delete the ufi entry.
-                                   Defaults to True.
-        :psci_enable: Enabling the psci. Defaults to True.
-        :host_working_directory: The host working directory. Defaults to None.
-        :disable_boot_configuration: Disables boot configuration through images.txt and board.txt. When
-                                     this is ``True``, those two files will not be overwritten in VEMSD.
-                                     This option may be necessary if the firmware version in the ``TC2``
-                                     is not compatible with the templates in WA. Please note that enabling
-                                     this will prevent you form being able to set ``boot_firmware`` and
-                                     ``mode`` parameters. Defaults to ``False``.
-
-    TC2 can also have a number of different booting mode, which are:
-
-        :mp_a7_only: Only the A7 cluster.
-        :mp_a7_bootcluster: Both A7 and A15 clusters, but it boots on A7
-                            cluster.
-        :mp_a15_only: Only the A15 cluster.
-        :mp_a15_bootcluster: Both A7 and A15 clusters, but it boots on A15
-                             clusters.
-        :iks_cpu: Only A7 cluster with only 2 cpus.
-        :iks_a15: Only A15 cluster.
-        :iks_a7: Same as iks_cpu
-        :iks_ns_a15: Both A7 and A15 clusters.
-        :iks_ns_a7: Both A7 and A15 clusters.
-
-    The difference between mp and iks is the scheduling policy.
-
-    TC2 takes the following runtime parameters
-
-        :a7_cores: Number of active A7 cores.
-        :a15_cores: Number of active A15 cores.
-        :a7_governor: CPUFreq governor for the A7 cluster.
-        :a15_governor: CPUFreq governor for the A15 cluster.
-        :a7_min_frequency: Minimum CPU frequency for the A7 cluster.
-        :a15_min_frequency: Minimum CPU frequency for the A15 cluster.
-        :a7_max_frequency: Maximum CPU frequency for the A7 cluster.
-        :a15_max_frequency: Maximum CPU frequency for the A7 cluster.
-        :irq_affinity: lambda x: Which cluster will receive IRQs.
-        :cpuidle: Whether idle states should be enabled.
-        :sysfile_values: A dict mapping a complete file path to the value that
-                         should be echo'd into it. By default, the file will be
-                         subsequently read to verify that the value was written
-                         into it with DeviceError raised otherwise. For write-only
-                         files, this check can be disabled by appending a ``!`` to
-                         the end of the file path.

-    Implements gem5 Linux device.
-
-    This class allows a user to connect WA to a simulation using gem5. The
-    connection to the device is made using the telnet connection of the
-    simulator, and is used for all commands. The simulator does not have ADB
-    support, and therefore we need to fall back to using standard shell
-    commands.
-
-    Files are copied into the simulation using a VirtIO 9P device in gem5. Files
-    are copied out of the simulated environment using the m5 writefile command
-    within the simulated system.
-
-    When starting the workload run, the simulator is automatically started by
-    Workload Automation, and a connection to the simulator is established. WA
-    will then wait for Android to boot on the simulated system (which can take
-    hours), prior to executing any other commands on the device. It is also
-    possible to resume from a checkpoint when starting the simulation. To do
-    this, please append the relevant checkpoint commands from the gem5
-    simulation script to the gem5_discription argument in the agenda.
-
-    Host system requirements:
-        * VirtIO support. We rely on diod on the host system. This can be
-          installed on ubuntu using the following command:
-
-                sudo apt-get install diod
-
-    Guest requirements:
-        * VirtIO support. We rely on VirtIO to move files into the simulation.
-          Please make sure that the following are set in the kernel
-          configuration:
