* This applies to:
* - hypercall arguments passed via a pointer to guest memory.
* - memory shared via the grant table mechanism (including PV I/O
* rings etc).
* - memory shared with the hypervisor (struct shared_info, struct

* Multiple hardware queues/rings:
* If supported, the backend will write the key "multi-queue-max-queues" to
* the directory for that vbd, and set its value to the maximum supported
* number of queues.
* Frontends that are aware of this feature and wish to use it can write the
* key "multi-queue-num-queues" with the number they wish to use, which must be
* greater than zero, and no more than the value reported by the backend in
* "multi-queue-max-queues".
*
* For frontends requesting just one queue, the usual event-channel and
* ring-ref keys are written as before, simplifying the backend processing
* to avoid distinguishing between a frontend that doesn't understand the
* multi-queue feature, and one that does, but requested only one queue.
*
* Frontends requesting two or more queues must not write the toplevel
* event-channel and ring-ref keys, instead writing those keys under sub-keys
* having the name "queue-N" where N is the integer ID of the queue/ring for
* which those keys belong. Queues are indexed from zero.
* For example, a frontend with two queues must write the following set of
* queue-related keys:
*
* /local/domain/1/device/vbd/0/multi-queue-num-queues = "2"
* /local/domain/1/device/vbd/0/queue-0 = ""
* /local/domain/1/device/vbd/0/queue-0/ring-ref = "<ring-ref#0>"
* /local/domain/1/device/vbd/0/queue-0/event-channel = "<evtchn#0>"

* /local/domain/1/device/vbd/0/queue-1/ring-ref = "<ring-ref#1>"
* /local/domain/1/device/vbd/0/queue-1/event-channel = "<evtchn#1>"
*
* It is also possible to use multiple queues/rings together with
* feature multi-page ring buffer.
* For example, a frontend requests two queues/rings and the size of each ring
* buffer is two pages must write the following set of related keys:
*
* /local/domain/1/device/vbd/0/multi-queue-num-queues = "2"
* /local/domain/1/device/vbd/0/ring-page-order = "1"
* /local/domain/1/device/vbd/0/queue-0 = ""

******************************************************************************

******************************************************************************
*/
#define XENDISPL_PROTOCOL_VERSION "1"
/*
******************************************************************************
* Main features provided by the protocol
******************************************************************************
* This protocol aims to provide a unified protocol which fits more
* sophisticated use-cases than a framebuffer device can handle. At the
* moment basic functionality is supported with the intention to be extended:
* o multiple dynamically allocated/destroyed framebuffers
* o buffers of arbitrary sizes
* o buffer allocation at either back or front end
* o better configuration options including multiple display support
*
* Note: existing fbif can be used together with displif running at the
* same time, e.g. on Linux one provides framebuffer and another DRM/KMS
*
* Note: display resolution (XenStore's "resolution" property) defines
* visible area of the virtual display. At the same time resolution of
* the display and frame buffers may differ: buffers can be smaller, equal
* or bigger than the visible area. This is to enable use-cases, where backend
* may do some post-processing of the display and frame buffers supplied,
* e.g. those buffers can be just a part of the final composition.
*
******************************************************************************
* Direction of improvements
******************************************************************************
* Future extensions to the existing protocol may include:
* o display/connector cloning
* o allocation of objects other than display buffers
* o plane/overlay support
* o scaling support
* o rotation support
*
******************************************************************************
* Feature and Parameter Negotiation
******************************************************************************
*
* Front->back notifications: when enqueuing a new request, sending a
* notification can be made conditional on xendispl_req (i.e., the generic
* hold-off mechanism provided by the ring macros). Backends must set
* xendispl_req appropriately (e.g., using RING_FINAL_CHECK_FOR_REQUESTS()).
*
* Back->front notifications: when enqueuing a new response, sending a
* notification can be made conditional on xendispl_resp (i.e., the generic
* hold-off mechanism provided by the ring macros). Frontends must set
* xendispl_resp appropriately (e.g., using RING_FINAL_CHECK_FOR_RESPONSES()).
*
* The two halves of a para-virtual display driver utilize nodes within
* XenStore to communicate capabilities and to negotiate operating parameters.
* This section enumerates these nodes which reside in the respective front and
* backend portions of XenStore, following the XenBus convention.
*
* All data in XenStore is stored as strings. Nodes specifying numeric
* values are encoded in decimal. Integer value ranges listed below are
* expressed as fixed sized integer types capable of storing the conversion
* of a properly formated node string, without loss of information.
*
******************************************************************************
* Example configuration
******************************************************************************
*
* Note: depending on the use-case backend can expose more display connectors
* than the underlying HW physically has by employing SW graphics compositors
*
* This is an example of backend and frontend configuration:
*

*
*------------------------------- Recovery flow -------------------------------
*
* In case of frontend unrecoverable errors backend handles that as
* if frontend goes into the XenbusStateClosed state.
*
* In case of backend unrecoverable errors frontend tries removing
* the virtualized device. If this is possible at the moment of error,
* then frontend goes into the XenbusStateInitialising state and is ready for
* new connection with backend. If the virtualized device is still in use and
* cannot be removed, then frontend goes into the XenbusStateReconfiguring state
* until either the virtualized device is removed or backend initiates a new
* connection. On the virtualized device removal frontend goes into the
* XenbusStateInitialising state.
*
* Note on XenbusStateReconfiguring state of the frontend: if backend has
* unrecoverable errors then frontend cannot send requests to the backend
* and thus cannot provide functionality of the virtualized device anymore.
* After backend is back to normal the virtualized device may still hold some
* state: configuration in use, allocated buffers, client application state etc.
* In most cases, this will require frontend to implement complex recovery
* reconnect logic. Instead, by going into XenbusStateReconfiguring state,
* frontend will make sure no new clients of the virtualized device are
* accepted, allow existing client(s) to exit gracefully by signaling error
* state etc.
* Once all the clients are gone frontend can reinitialize the virtualized
* device and get into XenbusStateInitialising state again signaling the
* backend that a new connection can be made.
*
* There are multiple conditions possible under which frontend will go from
* XenbusStateReconfiguring into XenbusStateInitialising, some of them are OS
* specific. For example:
* 1. The underlying OS framework may provide callbacks to signal that the last
* client of the virtualized device has gone and the device can be removed
* 2. Frontend can schedule a deferred work (timer/tasklet/workqueue)
* to periodically check if this is the right time to re-try removal of
* the virtualized device.
* 3. By any other means.

*****************************************************************************
* Feature and Parameter Negotiation
*****************************************************************************
*
* The two halves of a para-virtual driver utilize nodes within
* XenStore to communicate capabilities and to negotiate operating parameters.
* This section enumerates these nodes which reside in the respective front and
* backend portions of XenStore, following XenBus convention.
*
* All data in XenStore is stored as strings. Nodes specifying numeric
* values are encoded in decimal. Integer value ranges listed below are
* expressed as fixed sized integer types capable of storing the conversion
* of a properly formated node string, without loss of information.
*
*****************************************************************************
* Backend XenBus Nodes
*****************************************************************************
*
*---------------------------- Features supported ----------------------------
*
* Capable backend advertises supported features by publishing
* corresponding entries in XenStore and puts 1 as the value of the entry.
* If a feature is not supported then 0 must be set or feature entry omitted.
*
* feature-disable-keyboard
* Values: <uint>
*
* If there is no need to expose a virtual keyboard device by the
* frontend then this must be set to 1.
*
* feature-disable-pointer
* Values: <uint>
*
* If there is no need to expose a virtual pointer device by the
* frontend then this must be set to 1.
*
* feature-abs-pointer
* Values: <uint>
*
* Backends, which support reporting of absolute coordinates for pointer
* device should set this to 1.
*
* feature-multi-touch
* Values: <uint>
*
* Backends, which support reporting of multi-touch events
* should set this to 1.
*
* feature-raw-pointer
* Values: <uint>
*
* Backends, which support reporting raw (unscaled) absolute coordinates
* for pointer devices should set this to 1. Raw (unscaled) values have
* a range of [0, 0x7fff].
*
*----------------------- Device Instance Parameters ------------------------
*
* unique-id
* Values: <string>
*
* After device instance initialization it is assigned a unique ID,
* so every instance of the frontend can be identified by the backend
* by this ID. This can be UUID or such.
*
*------------------------- Pointer Device Parameters ------------------------
*
* width
* Values: <uint>
*
* Maximum X coordinate (width) to be used by the frontend
* while reporting input events, pixels, [0; UINT32_MAX].
*
* height
* Values: <uint>
*
* Maximum Y coordinate (height) to be used by the frontend
* while reporting input events, pixels, [0; UINT32_MAX].
*
*----------------------- Multi-touch Device Parameters ----------------------
*
* multi-touch-num-contacts
* Values: <uint>
*
* Number of simultaneous touches reported.
*
* multi-touch-width
* Values: <uint>
*
* Width of the touch area to be used by the frontend
* while reporting input events, pixels, [0; UINT32_MAX].
*
* multi-touch-height
* Values: <uint>
*
* Height of the touch area to be used by the frontend
* while reporting input events, pixels, [0; UINT32_MAX].
*
*****************************************************************************
* Frontend XenBus Nodes
*****************************************************************************
*
*------------------------------ Feature request -----------------------------
*
* Capable frontend requests features from backend via setting corresponding
* entries to 1 in XenStore. Requests for features not advertised as supported
* by the backend have no effect.
*
* request-abs-pointer
* Values: <uint>
*
* Request backend to report absolute pointer coordinates
* (XENKBD_TYPE_POS) instead of relative ones (XENKBD_TYPE_MOTION).
*
* request-multi-touch
* Values: <uint>
*
* Request backend to report multi-touch events.
*
* request-raw-pointer
* Values: <uint>
*
* Request backend to report raw unscaled absolute pointer coordinates.
* This option is only valid if request-abs-pointer is also set.
* Raw unscaled coordinates have the range [0, 0x7fff]
*
*----------------------- Request Transport Parameters -----------------------
*
* event-channel
* Values: <uint>
*
* The identifier of the Xen event channel used to signal activity
* in the ring buffer.
*
* page-gref
* Values: <uint>
*
* The Xen grant reference granting permission for the backend to map
* a sole page in a single page sized event ring buffer.
*
* page-ref
* Values: <uint>
*
* OBSOLETE, not recommended for use.
* PFN of the shared page.

* "feature-multicast-control" and "feature-dynamic-multicast-control"
* advertise the capability to filter ethernet multicast packets in the
* backend. If the frontend wishes to take advantage of this feature then
* it may set "request-multicast-control". If the backend only advertises

* "feature-dynamic-multicast-control" then "request-multicast-control"
* may be set by the frontend at any time. In this case, the backend will
* watch the value and re-sample on watch events.
*
* If "request-multicast-control" is set then the backend transmit side should
* no longer flood multicast packets to the frontend, it should instead drop any

* Control ring
* ============
*
* Some features, such as hashing (detailed below), require a
* significant amount of out-of-band data to be passed from frontend to
* backend. Use of xenstore is not suitable for large quantities of data
* because of quota limitations and so a dedicated 'control ring' is used.
* The ability of the backend to use a control ring is advertised by
* setting:
*
* /local/domain/X/backend/vif/<domid>/<vif>/feature-ctrl-ring = "1"
*
* The frontend provides a control ring to the backend by setting:
*
* /local/domain/<domid>/device/vif/<vif>/ctrl-ring-ref = <gref>
* /local/domain/<domid>/device/vif/<vif>/event-channel-ctrl = <port>
*
* where <gref> is the grant reference of the shared page used to
* implement the control ring and <port> is an event channel to be used
* as a mailbox interrupt. These keys must be set before the frontend
* moves into the connected state.
*
* The control ring uses a fixed request/response message size and is
* balanced (i.e. one request to one response), so operationally it is much
* the same as a transmit or receive ring.
* Note that there is no requirement that responses are issued in the same
* order as requests.
*/
/*
* Link state
* ==========
*
* The backend can advertise its current link (carrier) state to the
* frontend using the /local/domain/X/backend/vif/<domid>/<vif>/carrier
* node. If this node is not present, then the frontend should assume that
* the link is up (for compatibility with backends that do not implement
* this feature). If this node is present, then a value of "0" should be
* interpreted by the frontend as the link being down (no carrier) and a
* value of "1" should be interpreted as the link being up (carrier
* present).

* XEN_NETIF_CTRL_STATUS_SUCCESS - Operation successful
*
* NOTE: Setting data[0] to XEN_NETIF_CTRL_HASH_ALGORITHM_NONE disables

* to queues (which is the default behaviour).
*
* XEN_NETIF_CTRL_TYPE_GET_HASH_FLAGS

* data = supported hash types (if operation was successful)
*
* NOTE: A valid hash algorithm must be selected before this operation can
* succeed.
*
* XEN_NETIF_CTRL_TYPE_SET_HASH_FLAGS
* ----------------------------------
*
* This is sent by the frontend to set the types of hash that the backend
* should calculate. (See above for hash type definitions).
* Note that the 'maximal' type of hash should always be chosen. For
* example, if the frontend sets both IPV4 and IPV4_TCP hash types then

* succeed.
* Also, setting data[0] to zero disables hashing and the backend
* is free to choose how it steers packets to queues.
*
* XEN_NETIF_CTRL_TYPE_SET_HASH_KEY

*
* NOTE: Any key octets not specified are assumed to be zero (the key
* is assumed to be empty by default) and specifying a new key
* invalidates any previous key, hence specifying a key size of
* zero will clear the key (which ensures that the calculated hash
* will always be zero).
* The maximum size of key is algorithm and backend specific, but

* XEN_NETIF_CTRL_TYPE_SET_HASH_MAPPING_SIZE
* -------------------------------------
*
* This is sent by the frontend to set the actual size of the mapping

* devices. Everything is stored in /local/domain/<backend_domid>/backend/vscsi/.
* The xenstore layout looks like this (dom0 is assumed to be the backend_domid):
*
* <domid>/<vhost>/feature-host = "0"
* <domid>/<vhost>/frontend = "/local/domain/<domid>/device/vscsi/0"
* <domid>/<vhost>/frontend-id = "<domid>"
* <domid>/<vhost>/online = "1"
* <domid>/<vhost>/state = "4"
* <domid>/<vhost>/vscsi-devs/dev-0/p-dev = "8:0:2:1" or "naa.wwn:lun"
* <domid>/<vhost>/vscsi-devs/dev-0/state = "4"
* <domid>/<vhost>/vscsi-devs/dev-0/v-dev = "0:0:0:0"
* <domid>/<vhost>/vscsi-devs/dev-1/p-dev = "8:0:2:2"
* <domid>/<vhost>/vscsi-devs/dev-1/state = "4"
* <domid>/<vhost>/vscsi-devs/dev-1/v-dev = "0:0:1:0"
*
* The frontend driver maintains its state in
* /local/domain/<domid>/device/vscsi/.
*
* <vhost>/backend = "/local/domain/0/backend/vscsi/<domid>/<vhost>"
* <vhost>/backend-id = "0"
* <vhost>/event-channel = "20"
* <vhost>/ring-ref = "43"
* <vhost>/state = "4"
* <vhost>/vscsi-devs/dev-0/state = "4"
* <vhost>/vscsi-devs/dev-1/state = "4"
*
* In addition to the entries for backend and frontend these flags are stored
* for the toolstack:
*
* <domid>/<vhost>/vscsi-devs/dev-1/p-devname = "/dev/$device"
* <domid>/<vhost>/libxl_ctrl_index = "0"
*
*
* Backend/frontend protocol
* =========================
*
* To create a vhost along with a device:
* <domid>/<vhost>/feature-host = "0"
* <domid>/<vhost>/frontend = "/local/domain/<domid>/device/vscsi/0"
* <domid>/<vhost>/frontend-id = "<domid>"
* <domid>/<vhost>/online = "1"
* <domid>/<vhost>/state = "1"
* <domid>/<vhost>/vscsi-devs/dev-0/p-dev = "8:0:2:1"
* <domid>/<vhost>/vscsi-devs/dev-0/state = "1"
* <domid>/<vhost>/vscsi-devs/dev-0/v-dev = "0:0:0:0"
* Wait for <domid>/<vhost>/state + <domid>/<vhost>/vscsi-devs/dev-0/state become 4
*
* To add another device to a vhost:
* <domid>/<vhost>/state = "7"
* <domid>/<vhost>/vscsi-devs/dev-1/p-dev = "8:0:2:2"
* <domid>/<vhost>/vscsi-devs/dev-1/state = "1"
* <domid>/<vhost>/vscsi-devs/dev-1/v-dev = "0:0:1:0"
* Wait for <domid>/<vhost>/state + <domid>/<vhost>/vscsi-devs/dev-1/state become 4
*
* To remove a device from a vhost:
* <domid>/<vhost>/state = "7"
* <domid>/<vhost>/vscsi-devs/dev-1/state = "5"
* Wait for <domid>/<vhost>/state to become 4
* Wait for <domid>/<vhost>/vscsi-devs/dev-1/state become 6
* Remove <domid>/<vhost>/vscsi-devs/dev-1/{state,p-dev,v-dev,p-devname}
