-We assign a zspage to ZS_ALMOST_EMPTY fullness group when n <= N / f, where
-
-* n = number of allocated objects
-* N = total number of objects zspage can store
-* f = fullness_threshold_frac(ie, 4 at the moment)
-
-Similarly, we assign zspage to:
-
-* ZS_ALMOST_FULL  when n > N / f
-* ZS_EMPTY        when n == 0
-* ZS_FULL         when n == N
-
+Each zspage maintains inuse counter which keeps track of the number of
+objects stored in the zspage.  The inuse counter determines the zspage's
+"fullness group" which is calculated as the ratio of the "inuse" objects to
+the total number of objects the zspage can hold (objs_per_zspage). The
+closer the inuse counter is to objs_per_zspage, the better.

+=======================
+Linux UVC Gadget Driver
+=======================
+
+Overview
+--------
+The UVC Gadget driver is a driver for hardware on the *device* side of a USB
+connection. It is intended to run on a Linux system that has USB device-side
+hardware such as boards with an OTG port.
+
+On the device system, once the driver is bound it appears as a V4L2 device with
+the output capability.
+
+On the host side (once connected via USB cable), a device running the UVC Gadget
+driver *and controlled by an appropriate userspace program* should appear as a UVC
+specification compliant camera, and function appropriately with any program
+designed to handle them. The userspace program running on the device system can
+queue image buffers from a variety of sources to be transmitted via the USB
+connection. Typically this would mean forwarding the buffers from a camera sensor
+peripheral, but the source of the buffer is entirely dependent on the userspace
+companion program.
+
+Configuring the device kernel
+-----------------------------
+The Kconfig options USB_CONFIGFS, USB_LIBCOMPOSITE, USB_CONFIGFS_F_UVC and
+USB_F_UVC must be selected to enable support for the UVC gadget.
+
+Configuring the gadget through configfs
+---------------------------------------
+The UVC Gadget expects to be configured through configfs using the UVC function.
+This allows a significant degree of flexibility, as many of a UVC device's
+settings can be controlled this way.
+
+Not all of the available attributes are described here. For a complete enumeration
+see Documentation/ABI/testing/configfs-usb-gadget-uvc
+
+Assumptions
+~~~~~~~~~~~
+This section assumes that you have mounted configfs at `/sys/kernel/config` and
+created a gadget as `/sys/kernel/config/usb_gadget/g1`.
+
+The UVC Function
+~~~~~~~~~~~~~~~~
+
+The first step is to create the UVC function:
+
+.. code-block:: bash
+
+	# These variables will be assumed throughout the rest of the document
+	CONFIGFS="/sys/kernel/config"
+	GADGET="$CONFIGFS/usb_gadget/g1"
+	FUNCTION="$GADGET/functions/uvc.0"
+
+	mkdir -p $FUNCTION
+
+Formats and Frames
+~~~~~~~~~~~~~~~~~~
+
+You must configure the gadget by telling it which formats you support, as well
+as the frame sizes and frame intervals that are supported for each format. In
+the current implementation there is no way for the gadget to refuse to set a
+format that the host instructs it to set, so it is important that this step is
+completed *accurately* to ensure that the host never asks for a format that
+can't be provided.
+
+Formats are created under the streaming/uncompressed and streaming/mjpeg configfs
+groups, with the framesizes created under the formats in the following
+structure:
+
+::
+
+	uvc.0 +
+	      |
+	      + streaming +
+			  |
+			  + mjpeg +
+			  |       |
+			  |       + mjpeg +
+			  |	       |
+			  |	       + 720p
+			  |	       |
+			  |	       + 1080p
+			  |
+			  + uncompressed +
+					 |
+					 + yuyv +
+						|
+						+ 720p
+						|
+						+ 1080p
+
+Each frame can then be configured with a width and height, plus the maximum
+buffer size required to store a single frame, and finally with the supported
+frame intervals for that format and framesize. Width and height are enumerated in
+units of pixels, frame interval in units of 100ns. To create the structure
+above with 2, 15 and 100 fps frameintervals for each framesize for example you
+might do:
+
+.. code-block:: bash
+
+	create_frame() {
+		# Example usage:
+		# create_frame <width> <height> <group> <format name>
+
+		WIDTH=$1
+		HEIGHT=$2
+		FORMAT=$3
+		NAME=$4
+
+		wdir=$FUNCTION/streaming/$FORMAT/$NAME/${HEIGHT}p
+
+		mkdir -p $wdir
+		echo $WIDTH > $wdir/wWidth
+		echo $HEIGHT > $wdir/wHeight
+		echo $(( $WIDTH * $HEIGHT * 2 )) > $wdir/dwMaxVideoFrameBufferSize
+		cat <<EOF > $wdir/dwFrameInterval
+	666666
+	100000
+	5000000
+	EOF
+	}
+
+	create_frame 1280 720 mjpeg mjpeg
+	create_frame 1920 1080 mjpeg mjpeg
+	create_frame 1280 720 uncompressed yuyv
+	create_frame 1920 1080 uncompressed yuyv
+
+The only uncompressed format currently supported is YUYV, which is detailed at
+Documentation/userspace-api/media/v4l/pixfmt-packed.yuv.rst.
+
+Color Matching Descriptors
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+It's possible to specify some colometry information for each format you create.
+This step is optional, and default information will be included if this step is
+skipped; those default values follow those defined in the Color Matching Descriptor
+section of the UVC specification.
+
+To create a Color Matching Descriptor, create a configfs item and set its three
+attributes to your desired settings and then link to it from the format you wish
+it to be associated with:
+
+.. code-block:: bash
+
+	# Create a new Color Matching Descriptor
+
+	mkdir $FUNCTION/streaming/color_matching/yuyv
+	pushd $FUNCTION/streaming/color_matching/yuyv
+
+	echo 1 > bColorPrimaries
+	echo 1 > bTransferCharacteristics
+	echo 4 > bMatrixCoefficients
+
+	popd
+
+	# Create a symlink to the Color Matching Descriptor from the format's config item
+	ln -s $FUNCTION/streaming/color_matching/yuyv $FUNCTION/streaming/uncompressed/yuyv
+
+For details about the valid values, consult the UVC specification. Note that a
+default color matching descriptor exists and is used by any format which does
+not have a link to a different Color Matching Descriptor. It's possible to
+change the attribute settings for the default descriptor, so bear in mind that if
+you do that you are altering the defaults for any format that does not link to
+a different one.
+
+
+Header linking
+~~~~~~~~~~~~~~
+
+The UVC specification requires that Format and Frame descriptors be preceded by
+Headers detailing things such as the number and cumulative size of the different
+Format descriptors that follow. This and similar operations are acheived in
+configfs by linking between the configfs item representing the header and the
+config items representing those other descriptors, in this manner:
+
+.. code-block:: bash
+
+	mkdir $FUNCTION/streaming/header/h
+
+	# This section links the format descriptors and their associated frames
+	# to the header
+	cd $FUNCTION/streaming/header/h
+	ln -s ../../uncompressed/yuyv
+	ln -s ../../mjpeg/mjpeg
+
+	# This section ensures that the header will be transmitted for each
+	# speed's set of descriptors. If support for a particular speed is not
+	# needed then it can be skipped here.
+	cd ../../class/fs
+	ln -s ../../header/h
+	cd ../../class/hs
+	ln -s ../../header/h
+	cd ../../class/ss
+	ln -s ../../header/h
+	cd ../../../control
+	mkdir header/h
+	ln -s header/h class/fs
+	ln -s header/h class/ss
+
+
+Extension Unit Support
+~~~~~~~~~~~~~~~~~~~~~~
+
+A UVC Extension Unit (XU) basically provides a distinct unit to which control set
+and get requests can be addressed. The meaning of those control requests is
+entirely implementation dependent, but may be used to control settings outside
+of the UVC specification (for example enabling or disabling video effects). An
+XU can be inserted into the UVC unit chain or left free-hanging.
+
+Configuring an extension unit involves creating an entry in the appropriate
+directory and setting its attributes appropriately, like so:
+
+.. code-block:: bash
+
+	mkdir $FUNCTION/control/extensions/xu.0
+	pushd $FUNCTION/control/extensions/xu.0
+
+	# Set the bUnitID of the Processing Unit as the source for this
+	# Extension Unit
+	echo 2 > baSourceID
+
+	# Set this XU as the source of the default output terminal. This inserts
+	# the XU into the UVC chain between the PU and OT such that the final
+	# chain is IT > PU > XU.0 > OT
+	cat bUnitID > ../../terminal/output/default/baSourceID
+
+	# Flag some controls as being available for use. The bmControl field is
+	# a bitmap with each bit denoting the availability of a particular
+	# control. For example to flag the 0th, 2nd and 3rd controls available:
+	echo 0x0d > bmControls
+
+	# Set the GUID; this is a vendor-specific code identifying the XU.
+	echo -e -n "\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0a\x0b\x0c\x0d\x0e\x0f\x10" > guidExtensionCode
+
+	popd
+
+The bmControls attribute and the baSourceID attribute are multi-value attributes.
+This means that you may write multiple newline separated values to them. For
+example to flag the 1st, 2nd, 9th and 10th controls as being available you would
+need to write two values to bmControls, like so:
+
+.. code-block:: bash
+
+	cat << EOF > bmControls
+	0x03
+	0x03
+	EOF
+
+The multi-value nature of the baSourceID attribute belies the fact that XUs can
+be multiple-input, though note that this currently has no significant effect.
+
+The bControlSize attribute reflects the size of the bmControls attribute, and
+similarly bNrInPins reflects the size of the baSourceID attributes. Both
+attributes are automatically increased / decreased as you set bmControls and
+baSourceID. It is also possible to manually increase or decrease bControlSize
+which has the effect of truncating entries to the new size, or padding entries
+out with 0x00, for example:
+
+::
+
+	$ cat bmControls
+	0x03
+	0x05
+
+	$ cat bControlSize
+	2
+
+	$ echo 1 > bControlSize
+	$ cat bmControls
+	0x03
+
+	$ echo 2 > bControlSize
+	$ cat bmControls
+	0x03
+	0x00
+
+bNrInPins and baSourceID function in the same way.
+
+Custom Strings Support
+~~~~~~~~~~~~~~~~~~~~~~
+
+String descriptors that provide a textual description for various parts of a
+USB device can be defined in the usual place within USB configfs, and may then
+be linked to from the UVC function root or from Extension Unit directories to
+assign those strings as descriptors:
+
+.. code-block:: bash
+
+	# Create a string descriptor in us-EN and link to it from the function
+	# root. The name of the link is significant here, as it declares this
+	# descriptor to be intended for the Interface Association Descriptor.
+	# Other significant link names at function root are vs0_desc and vs1_desc
+	# For the VideoStreaming Interface 0/1 Descriptors.

+
+The interrupt endpoint
+~~~~~~~~~~~~~~~~~~~~~~
+
+The VideoControl interface has an optional interrupt endpoint which is by default
+disabled. This is intended to support delayed response control set requests for
+UVC (which should respond through the interrupt endpoint rather than tying up
+endpoint 0). At present support for sending data through this endpoint is missing
+and so it is left disabled to avoid confusion. If you wish to enable it you can
+do so through the configfs attribute:
+
+.. code-block:: bash
+
+	echo 1 > $FUNCTION/control/enable_interrupt_ep
+
+Bandwidth configuration
+~~~~~~~~~~~~~~~~~~~~~~~
+
+There are three attributes which control the bandwidth of the USB connection.
+These live in the function root and can be set within limits:
+
+.. code-block:: bash
+
+	# streaming_interval sets bInterval. Values range from 1..255
+	echo 1 > $FUNCTION/streaming_interval
+
+	# streaming_maxpacket sets wMaxPacketSize. Valid values are 1024/2048/3072
+	echo 3072 > $FUNCTION/streaming_maxpacket
+
+	# streaming_maxburst sets bMaxBurst. Valid values are 1..15
+	echo 1 > $FUNCTION/streaming_maxburst
+
+
+The values passed here will be clamped to valid values according to the UVC
+specification (which depend on the speed of the USB connection). To understand
+how the settings influence bandwidth you should consult the UVC specifications,
+but a rule of thumb is that increasing the streaming_maxpacket setting will
+improve bandwidth (and thus the maximum possible framerate), whilst the same is
+true for streaming_maxburst provided the USB connection is running at SuperSpeed.
+Increasing streaming_interval will reduce bandwidth and framerate.
+
+The userspace application
+-------------------------
+By itself, the UVC Gadget driver cannot do anything particularly interesting. It
+must be paired with a userspace program that responds to UVC control requests and
+fills buffers to be queued to the V4L2 device that the driver creates. How those
+things are achieved is implementation dependent and beyond the scope of this
+document, but a reference application can be found at https://gitlab.freedesktop.org/camera/uvc-gadget

- * struct ioasid_allocator_data - Internal data structure to hold information

- *
- * - Default allocator always has its own XArray to track the IOASIDs allocated.
- * - Custom allocators may share allocation helpers with different private data.
- *   Custom allocators that share the same helper functions also share the same
- *   XArray.
- * Rules:
- * 1. Default allocator is always available, not dynamically registered. This is
- *    to prevent race conditions with early boot code that want to register
- *    custom allocators or allocate IOASIDs.
- * 2. Custom allocators take precedence over the default allocator.
- * 3. When all custom allocators sharing the same helper functions are
- *    unregistered (e.g. due to hotplug), all outstanding IOASIDs must be
- *    freed. Otherwise, outstanding IOASIDs will be lost and orphaned.
- * 4. When switching between custom allocators sharing the same helper
- *    functions, outstanding IOASIDs are preserved.
- * 5. When switching between custom allocator and default allocator, all IOASIDs
- *    must be freed to ensure unadulterated space for the new allocator.
