- *        about the device state to be transitioned to.
- *      - The vendor driver should take the necessary actions to change the
- *        device state. After successful transition to a given state, the
- *        vendor driver should return success on write(device_state, state)
- *        system call. If the device state transition fails, the vendor driver
- *        should return an appropriate -errno for the fault condition.
- *      - On the user application side, if the device state transition fails,
- *	  that is, if write(device_state, state) returns an error, read
- *	  device_state again to determine the current state of the device from
- *	  the vendor driver.
- *      - The vendor driver should return previous state of the device unless
- *        the vendor driver has encountered an internal error, in which case
- *        the vendor driver may report the device_state VFIO_DEVICE_STATE_ERROR.
- *      - The user application must use the device reset ioctl to recover the
- *        device from VFIO_DEVICE_STATE_ERROR state. If the device is
- *        indicated to be in a valid device state by reading device_state, the
- *        user application may attempt to transition the device to any valid
- *        state reachable from the current state or terminate itself.
- *
- *      device_state consists of 3 bits:
- *      - If bit 0 is set, it indicates the _RUNNING state. If bit 0 is clear,
- *        it indicates the _STOP state. When the device state is changed to
- *        _STOP, driver should stop the device before write() returns.
- *      - If bit 1 is set, it indicates the _SAVING state, which means that the

- * 0. Default state of VFIO device is _RUNNING when the user application starts.
- * 1. During normal shutdown of the user application, the user application may
- *    optionally change the VFIO device state from _RUNNING to _STOP. This
- *    transition is optional. The vendor driver must support this transition but
- *    must not require it.
- * 2. When the user application saves state or suspends the application, the
- *    device state transitions from _RUNNING to stop-and-copy and then to _STOP.
- *    On state transition from _RUNNING to stop-and-copy, driver must stop the
- *    device, save the device state and send it to the application through the
- *    migration region. The sequence to be followed for such transition is given
- *    below.
- * 3. In live migration of user application, the state transitions from _RUNNING
- *    to pre-copy, to stop-and-copy, and to _STOP.
- *    On state transition from _RUNNING to pre-copy, the driver should start
- *    gathering the device state while the application is still running and send
- *    the device state data to application through the migration region.
- *    On state transition from pre-copy to stop-and-copy, the driver must stop
- *    the device, save the device state and send it to the user application
- *    through the migration region.
- *    Vendor drivers must support the pre-copy state even for implementations
- *    where no data is provided to the user before the stop-and-copy state. The
- *    user must not be required to consume all migration data before the device
- *    transitions to a new state, including the stop-and-copy state.
- *    The sequence to be followed for above two transitions is given below.
- * 4. To start the resuming phase, the device state should be transitioned from
- *    the _RUNNING to the _RESUMING state.
- *    In the _RESUMING state, the driver should use the device state data
- *    received through the migration region to resume the device.
- * 5. After providing saved device data to the driver, the application should
- *    change the state from _RESUMING to _RUNNING.
- *
- * reserved:
- *      Reads on this field return zero and writes are ignored.
- *
- * pending_bytes: (read only)
- *      The number of pending bytes still to be migrated from the vendor driver.
- *
- * data_offset: (read only)
- *      The user application should read data_offset field from the migration
- *      region. The user application should read the device data from this
- *      offset within the migration region during the _SAVING state or write
- *      the device data during the _RESUMING state. See below for details of
- *      sequence to be followed.
- *
- * data_size: (read/write)
- *      The user application should read data_size to get the size in bytes of
- *      the data copied in the migration region during the _SAVING state and
- *      write the size in bytes of the data copied in the migration region
- *      during the _RESUMING state.
- *
- * The format of the migration region is as follows:
- *  ------------------------------------------------------------------
- * |vfio_device_migration_info|    data section                      |
- * |                          |     ///////////////////////////////  |
- * ------------------------------------------------------------------
- *   ^                              ^
- *  offset 0-trapped part        data_offset
- *
- * The structure vfio_device_migration_info is always followed by the data
- * section in the region, so data_offset will always be nonzero. The offset
- * from where the data is copied is decided by the kernel driver. The data
- * section can be trapped, mmapped, or partitioned, depending on how the kernel
- * driver defines the data section. The data section partition can be defined
- * as mapped by the sparse mmap capability. If mmapped, data_offset must be
- * page aligned, whereas initial section which contains the
- * vfio_device_migration_info structure, might not end at the offset, which is
- * page aligned. The user is not required to access through mmap regardless
- * of the capabilities of the region mmap.
- * The vendor driver should determine whether and how to partition the data
- * section. The vendor driver should return data_offset accordingly.
- *
- * The sequence to be followed while in pre-copy state and stop-and-copy state
- * is as follows:
- * a. Read pending_bytes, indicating the start of a new iteration to get device
- *    data. Repeated read on pending_bytes at this stage should have no side
- *    effects.
- *    If pending_bytes == 0, the user application should not iterate to get data
- *    for that device.
- *    If pending_bytes > 0, perform the following steps.
- * b. Read data_offset, indicating that the vendor driver should make data
- *    available through the data section. The vendor driver should return this
- *    read operation only after data is available from (region + data_offset)
- *    to (region + data_offset + data_size).
- * c. Read data_size, which is the amount of data in bytes available through
- *    the migration region.
- *    Read on data_offset and data_size should return the offset and size of
- *    the current buffer if the user application reads data_offset and
- *    data_size more than once here.
- * d. Read data_size bytes of data from (region + data_offset) from the
- *    migration region.
- * e. Process the data.
- * f. Read pending_bytes, which indicates that the data from the previous
- *    iteration has been read. If pending_bytes > 0, go to step b.
- *
- * The user application can transition from the _SAVING|_RUNNING
- * (pre-copy state) to the _SAVING (stop-and-copy) state regardless of the
- * number of pending bytes. The user application should iterate in _SAVING
- * (stop-and-copy) until pending_bytes is 0.
- *
- * The sequence to be followed while _RESUMING device state is as follows:
- * While data for this device is available, repeat the following steps:
- * a. Read data_offset from where the user application should write data.
- * b. Write migration data starting at the migration region + data_offset for
- *    the length determined by data_size from the migration source.
- * c. Write data_size, which indicates to the vendor driver that data is
- *    written in the migration region. Vendor driver must return this write
- *    operations on consuming data. Vendor driver should apply the
- *    user-provided migration region data to the device resume state.
- *
- * If an error occurs during the above sequences, the vendor driver can return
- * an error code for next read() or write() operation, which will terminate the
- * loop. The user application should then take the next necessary action, for
- * example, failing migration or terminating the user application.
- *
- * For the user application, data is opaque. The user application should write
- * data in the same order as the data is received and the data should be of
- * same transaction size at the source.

+ * The device migration Finite State Machine is described by the enum
+ * vfio_device_mig_state. Some of the FSM arcs will create a migration data
+ * transfer session by returning a FD, in this case the migration data will
+ * flow over the FD using read() and write() as discussed below.
+ *
+ * There are 5 states to support VFIO_MIGRATION_STOP_COPY:
+ *  RUNNING - The device is running normally
+ *  STOP - The device does not change the internal or external state
+ *  STOP_COPY - The device internal state can be read out
+ *  RESUMING - The device is stopped and is loading a new internal state
+ *  ERROR - The device has failed and must be reset
+ *
+ * And 1 optional state to support VFIO_MIGRATION_P2P:
+ *  RUNNING_P2P - RUNNING, except the device cannot do peer to peer DMA
+ *
+ * The FSM takes actions on the arcs between FSM states. The driver implements
+ * the following behavior for the FSM arcs:
+ *
+ * RUNNING_P2P -> STOP
+ * STOP_COPY -> STOP
+ *   While in STOP the device must stop the operation of the device. The device
+ *   must not generate interrupts, DMA, or any other change to external state.
+ *   It must not change its internal state. When stopped the device and kernel
+ *   migration driver must accept and respond to interaction to support external
+ *   subsystems in the STOP state, for example PCI MSI-X and PCI config space.
+ *   Failure by the user to restrict device access while in STOP must not result
+ *   in error conditions outside the user context (ex. host system faults).
+ *
+ *   The STOP_COPY arc will terminate a data transfer session.
+ *
+ * RESUMING -> STOP
+ *   Leaving RESUMING terminates a data transfer session and indicates the
+ *   device should complete processing of the data delivered by write(). The
+ *   kernel migration driver should complete the incorporation of data written
+ *   to the data transfer FD into the device internal state and perform
+ *   final validity and consistency checking of the new device state. If the
+ *   user provided data is found to be incomplete, inconsistent, or otherwise
+ *   invalid, the migration driver must fail the SET_STATE ioctl and
+ *   optionally go to the ERROR state as described below.
+ *
+ *   While in STOP the device has the same behavior as other STOP states
+ *   described above.
+ *
+ *   To abort a RESUMING session the device must be reset.
+ *
+ * RUNNING_P2P -> RUNNING
+ *   While in RUNNING the device is fully operational, the device may generate
+ *   interrupts, DMA, respond to MMIO, all vfio device regions are functional,
+ *   and the device may advance its internal state.
+ *
+ * RUNNING -> RUNNING_P2P
+ * STOP -> RUNNING_P2P
+ *   While in RUNNING_P2P the device is partially running in the P2P quiescent
+ *   state defined below.
+ *
+ * STOP -> STOP_COPY
+ *   This arc begin the process of saving the device state and will return a
+ *   new data_fd.
+ *
+ *   While in the STOP_COPY state the device has the same behavior as STOP
+ *   with the addition that the data transfers session continues to stream the
+ *   migration state. End of stream on the FD indicates the entire device
+ *   state has been transferred.
+ *
+ *   The user should take steps to restrict access to vfio device regions while
+ *   the device is in STOP_COPY or risk corruption of the device migration data
+ *   stream.
+ *
+ * STOP -> RESUMING
+ *   Entering the RESUMING state starts a process of restoring the device state
+ *   and will return a new data_fd. The data stream fed into the data_fd should
+ *   be taken from the data transfer output of a single FD during saving from
+ *   a compatible device. The migration driver may alter/reset the internal
+ *   device state for this arc if required to prepare the device to receive the
+ *   migration data.
+ *
+ * any -> ERROR
+ *   ERROR cannot be specified as a device state, however any transition request
+ *   can be failed with an errno return and may then move the device_state into
+ *   ERROR. In this case the device was unable to execute the requested arc and
+ *   was also unable to restore the device to any valid device_state.
+ *   To recover from ERROR VFIO_DEVICE_RESET must be used to return the
+ *   device_state back to RUNNING.
+ *
+ * The optional peer to peer (P2P) quiescent state is intended to be a quiescent
+ * state for the device for the purposes of managing multiple devices within a
+ * user context where peer-to-peer DMA between devices may be active. The
+ * RUNNING_P2P states must prevent the device from initiating
+ * any new P2P DMA transactions. If the device can identify P2P transactions
+ * then it can stop only P2P DMA, otherwise it must stop all DMA. The migration
+ * driver must complete any such outstanding operations prior to completing the
+ * FSM arc into a P2P state. For the purpose of specification the states
+ * behave as though the device was fully running if not supported. Like while in
+ * STOP or STOP_COPY the user must not touch the device, otherwise the state
+ * can be exited.
+ *
+ * The remaining possible transitions are interpreted as combinations of the
+ * above FSM arcs. As there are multiple paths through the FSM arcs the path
+ * should be selected based on the following rules:
+ *   - Select the shortest path.
+ * Refer to vfio_mig_get_next_state() for the result of the algorithm.
+ *
+ * The automatic transit through the FSM arcs that make up the combination
+ * transition is invisible to the user. When working with combination arcs the
+ * user may see any step along the path in the device_state if SET_STATE
+ * fails. When handling these types of errors users should anticipate future
+ * revisions of this protocol using new states and those states becoming
+ * visible in this case.
+ *
+ * The optional states cannot be used with SET_STATE if the device does not
+ * support them. The user can discover if these states are supported by using
+ * VFIO_DEVICE_FEATURE_MIGRATION. By using combination transitions the user can
+ * avoid knowing about these optional states if the kernel driver supports them.
