+=======================================
+SSAM Debug Device and DebugFS Interface
+=======================================
+
+The ``surface_sam_debugfs`` module provides a DebugFS interface for the SSAM
+controller to allow for a (more or less) direct connection from userspace to
+the SAM EC. It is intended to be used for development and debugging, and
+therefore should not be used or relied upon in any other way. Note that this
+module is not loaded automatically, but instead must be loaded manually.
+
+The provided interface is accessible through the ``ssam/controller``
+device-file in debugfs, so, if the conventional mount path is being used,
+``/sys/kernel/debug/ssam/controller``. All functionality of this interface
+is provided via IOCTLs.
+
+
+Controller IOCTLs
+=================
+
+The following IOCTLs are provided:
+
+.. flat-table:: Controller IOCTLs
+ :widths: 1 1 1 1 4
+ :header-rows: 1
+
+ * - Type
+ - Number
+ - Direction
+ - Name
+ - Description
+
+ * - ``0xA5``
+ - ``0``
+ - ``R``
+ - ``GETVERSION``
+ - Get DebugFS controller interface version.
+
+ * - ``0xA5``
+ - ``1``
+ - ``WR``
+ - ``REQUEST``
+ - Perform synchronous SAM request.
+
+
+``GETVERSION``
+--------------
+
+Defined as ``_IOR(0xA5, 0, __u32)``.
+
+Gets the current interface version. This should be used to check for changes
+in the interface and determine if certain functionality is available. While
+the interface should under normal circumstances kept backward compatible, as
+this is a debug interface, backwards compatibility is not guaranteed.
+
+The version number follows the semantic versioning scheme, roughly meaning
+that an increment in the highest non-zero version number signals a breaking
+change. It can be decomposed as follows:
+
+.. flat-table:: Version Number Format
+ :widths: 2 1 3
+ :header-rows: 1
+
+ * - Offset (bytes)
+ - Type
+ - Description
+
+ * - ``0``
+ - |u8|
+ - Major
+
+ * - ``1``
+ - |u8|
+ - Minor
+
+ * - ``2``
+ - |u16|
+ - Patch
+
+The interface version is currently ``0.1.0``, i.e. ``0x00010000``.
+
+
+``REQUEST``
+-----------
+
+Defined as ``_IOWR(0xA5, 1, struct ssam_dbgdev_request)``.
+
+Executes a synchronous SAM request. The request specification is passed in
+as argument of type |ssam_dbgdev_request|, which is then written to/modified
+by the IOCTL to return status and result of the request.
+
+Request payload data must be allocated separately and is passed in via the
+``payload.data`` and ``payload.length`` members. If a response is required,
+the response buffer must be allocated by the caller and passed in via the
+``response.data`` member. The ``response.length`` member must be set to the
+capacity of this buffer, or if no response is required, zero. Upon
+completion of the request, the call will write the response to the response
+buffer (if its capacity allows it) and overwrite the length field with the
+actual size of the response, in bytes.
+
+Additionally, if the request has a response, this should be indicated via
+the request flags, as is done with in-kernel requests. Request flags can be
+set via the ``flags`` member and the values correspond to the values found
+in |ssam_request_flags|.
+
+Finally, the status of the request itself is returned in the ``status``
+member (a negative value indicating failure). Note that failure indication
+of the IOCTL is separated from failure indication of the request: The IOCTL
+returns a negative status code if anything failed during setup of the
+request (``-EFAULT``) or if the provided argument or any of its fields are
+invalid (``-EINVAL``). In this case, the status value of the request
+argument may be set, providing more detail on what went wrong (e.g.
+``-ENOMEM`` for out-of-memory), but this value may also be zero. The IOCTL
+will return with a zero status code in case the request has been set up,
+submitted, and completed (i.e. handed back to user-space) successfully from
+inside the IOCTL, but the request ``status`` member may still be negative in
+case the actual execution of the request failed after it has been submitted.
+
+A full definition of the argument struct is provided below:

+===================
+Surface ACPI Notify
+===================
+
+The Surface ACPI Notify (SAN) device provides the bridge between ACPI and
+SAM controller. Specifically, ACPI code can execute requests and handle
+battery and thermal events via this interface. In addition to this, events
+relating to the discrete GPU (dGPU) of the Surface Book 2 can be sent from
+ACPI code (note: the Surface Book 3 uses a different method for this). The
+only currently known event sent via this interface is a dGPU power-on
+notification. While this driver handles the former part internally, it only
+relays the dGPU events to any other driver interested via its public API and
+does not handle them.
+
+The public interface of this driver is split into two parts: Client
+registration and notifier-block registration.
+
+A client to the SAN interface can be linked as consumer to the SAN device
+via |san_client_link|. This can be used to ensure that the a client
+receiving dGPU events does not miss any events due to the SAN interface not
+being set up as this forces the client driver to unbind once the SAN driver
+is unbound.
+
+Notifier-blocks can be registered by any device for as long as the module is
+loaded, regardless of being linked as client or not. Registration is done
+with |san_dgpu_notifier_register|. If the notifier is not needed any more, it
+should be unregistered via |san_dgpu_notifier_unregister|.
+
+Consult the API documentation below for more details.
