/* hypercall calling convention
* ----------------------------
/*
* `incontents 50 arm_abi Hypercall Calling Convention
*
* A hypercall is issued using the ARM HVC instruction.
*
* A hypercall can take up to 5 arguments. These are passed in
* registers, the first argument in r0, the second argument in r1, the
* third in r2, the forth in r3 and the fifth in r4.
* registers, the first argument in x0/r0 (for arm64/arm32 guests
* respectively irrespective of whether the underlying hypervisor is
* 32- or 64-bit), the second argument in x1/r1, the third in x2/r2,
* the forth in x3/r3 and the fifth in x4/r4.
*
* The hypercall number is passed in r12.
* The hypercall number is passed in r12 (arm) or x16 (arm64). In both
* cases the relevant ARM procedure calling convention specifies this
* is an inter-procedure-call scratch register (e.g. for use in linker
* stubs). This use does not conflict with use during a hypercall.
*
* The HVC ISS must contain a Xen specific TAG: XEN_HYPERCALL_TAG.
*
* The return value is in r0.
* The return value is in x0/r0.
*
* The hypercall will clobber r12 and the argument registers used by
* that hypercall (except r0 which is the return value) i.e. a 2
* argument hypercall will clobber r1 and a 4 argument hypercall will
* clobber r1, r2 and r3.
* The hypercall will clobber x16/r12 and the argument registers used
* by that hypercall (except r0 which is the return value) i.e. in
* addition to x16/r12 a 2 argument hypercall will clobber x1/r1 and a
* 4 argument hypercall will clobber x1/r1, x2/r2 and x3/r3.
*
* Parameter structs passed to hypercalls are laid out according to
* the Procedure Call Standard for the ARM Architecture (AAPCS, AKA
* EABI) and Procedure Call Standard for the ARM 64-bit Architecture
* (AAPCS64). Where there is a conflict the 64-bit standard should be
* used regardless of guest type. Structures which are passed as
* hypercall arguments are always little endian.
*
* All memory which is shared with other entities in the system
* (including the hypervisor and other guests) must reside in memory
* which is mapped as Normal Inner-cacheable. 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
* vcpu_info, the grant table, etc).
*
* Any Inner cache allocation strategy (Write-Back, Write-Through etc)
* is acceptable. There is no restriction on the Outer-cacheability.
*/
/*
* `incontents 55 arm_hcall Supported Hypercalls
*
* Xen on ARM makes extensive use of hardware facilities and therefore
* only a subset of the potential hypercalls are required.
*
* Since ARM uses second stage paging any machine/physical addresses
* passed to hypercalls are Guest Physical Addresses (Intermediate
* Physical Addresses) unless otherwise noted.
*
* The following hypercalls (and sub operations) are supported on the
* ARM platform. Other hypercalls should be considered
* unavailable/unsupported.
*
* HYPERVISOR_memory_op
* All generic sub-operations
*

*
* HYPERVISOR_vcpu_op
* Exactly these sub-operations are supported:

* * VCPUOP_register_runstate_memory_area
*
*
* Other notes on the ARM ABI:
*
* - struct start_info is not exported to ARM guests.
*
* - struct shared_info is mapped by ARM guests using the
* HYPERVISOR_memory_op sub-op XENMEM_add_to_physmap, passing
* XENMAPSPACE_shared_info as space parameter.
*
* - All the per-cpu struct vcpu_info are mapped by ARM guests using the
* HYPERVISOR_vcpu_op sub-op VCPUOP_register_vcpu_info, including cpu0
* struct vcpu_info.
*
* - The grant table is mapped using the HYPERVISOR_memory_op sub-op
* XENMEM_add_to_physmap, passing XENMAPSPACE_grant_table as space
* parameter. The memory range specified under the Xen compatible
* hypervisor node on device tree can be used as target gpfn for the
* mapping.
*
* - Xenstore is initialized by using the two hvm_params
* HVM_PARAM_STORE_PFN and HVM_PARAM_STORE_EVTCHN. They can be read
* with the HYPERVISOR_hvm_op sub-op HVMOP_get_param.
*
* - The paravirtualized console is initialized by using the two
* hvm_params HVM_PARAM_CONSOLE_PFN and HVM_PARAM_CONSOLE_EVTCHN. They
* can be read with the HYPERVISOR_hvm_op sub-op HVMOP_get_param.
*
* - Event channel notifications are delivered using the percpu GIC
* interrupt specified under the Xen compatible hypervisor node on
* device tree.
*
* - The device tree Xen compatible node is fully described under Linux
* at Documentation/devicetree/bindings/arm/xen.txt.

* To make use of this feature, frontend should allocate two event
* channels for TX and RX, advertise them to backend as
* "event-channel-tx" and "event-channel-rx" respectively. If frontend
* doesn't want to use this feature, it just writes "event-channel"
* node as before.
*/
/*
* Multiple transmit and receive queues:
* If supported, the backend will write the key "multi-queue-max-queues" to
* the directory for that vif, 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", set to 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".
*
* Queues replicate the shared rings and event channels.
* "feature-split-event-channels" may optionally be used when using
* multiple queues, but is not mandatory.
*
* Each queue consists of one shared ring pair, i.e. there must be the same
* number of tx and rx rings.
*
* 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 (or event-channel-{tx,rx}) and {tx,rx}-ring-ref keys,
* instead writing those keys under sub-keys having the name "queue-N" where
* N is the integer ID of the queue for which those keys belong. Queues
* are indexed from zero. For example, a frontend with two queues and split
* event channels must write the following set of queue-related keys:
*
* /local/domain/1/device/vif/0/multi-queue-num-queues = "2"
* /local/domain/1/device/vif/0/queue-0 = ""
* /local/domain/1/device/vif/0/queue-0/tx-ring-ref = "<ring-ref-tx0>"
* /local/domain/1/device/vif/0/queue-0/rx-ring-ref = "<ring-ref-rx0>"
* /local/domain/1/device/vif/0/queue-0/event-channel-tx = "<evtchn-tx0>"
* /local/domain/1/device/vif/0/queue-0/event-channel-rx = "<evtchn-rx0>"
* /local/domain/1/device/vif/0/queue-1 = ""
* /local/domain/1/device/vif/0/queue-1/tx-ring-ref = "<ring-ref-tx1>"
* /local/domain/1/device/vif/0/queue-1/rx-ring-ref = "<ring-ref-rx1"
* /local/domain/1/device/vif/0/queue-1/event-channel-tx = "<evtchn-tx1>"
* /local/domain/1/device/vif/0/queue-1/event-channel-rx = "<evtchn-rx1>"
*
* If there is any inconsistency in the XenStore data, the backend may
* choose not to connect any queues, instead treating the request as an
* error. This includes scenarios where more (or fewer) queues were
* requested than the frontend provided details for.
*
* Mapping of packets to queues is considered to be a function of the
* transmitting system (backend or frontend) and is not negotiated
* between the two. Guests are free to transmit packets on any queue
* they choose, provided it has been set up correctly. Guests must be
* prepared to receive packets on any queue they have requested be set up.

/******************************************************************************
* TPM I/O interface for Xen guest OSes, v2
*
* Author: Daniel De Graaf <dgdegra@tycho.nsa.gov>
*
* This protocol emulates the request/response behavior of a TPM using a Xen
* shared memory interface. All interaction with the TPM is at the direction
* of the frontend, since a TPM (hardware or virtual) is a passive device -
* the backend only processes commands as requested by the frontend.
*
* The frontend sends a request to the TPM by populating the shared page with
* the request packet, changing the state to TPMIF_STATE_SUBMIT, and sending
* and event channel notification. When the backend is finished, it will set
* the state to TPMIF_STATE_FINISH and send an event channel notification.
*
* In order to allow long-running commands to be canceled, the frontend can
* at any time change the state to TPMIF_STATE_CANCEL and send a notification.
* The TPM can either finish the command (changing state to TPMIF_STATE_FINISH)
* or can cancel the command and change the state to TPMIF_STATE_IDLE. The TPM
* can also change the state to TPMIF_STATE_IDLE instead of TPMIF_STATE_FINISH
* if another reason for cancellation is required - for example, a physical
* TPM may cancel a command if the interface is seized by another locality.
*
* The TPM command format is defined by the TCG, and is available at
* http://www.trustedcomputinggroup.org/resources/tpm_main_specification
