|

*
|
||||
* This ioctl is used on the migration data FD in the precopy phase of the
|
||||
* migration data transfer. It returns an estimate of the current data sizes
|
||||
* remaining to be transferred. It allows the user to judge when it is
|
||||
* appropriate to leave PRE_COPY for STOP_COPY.
|
||||
*
|
||||
* This ioctl is valid only in PRE_COPY states and kernel driver should
|
||||
* return -EINVAL from any other migration state.
|
||||
*
|
||||
* The vfio_precopy_info data structure returned by this ioctl provides
|
||||
* estimates of data available from the device during the PRE_COPY states.
|
||||
* This estimate is split into two categories, initial_bytes and
|
||||
* dirty_bytes.
|
||||
*
|
||||
* The initial_bytes field indicates the amount of initial precopy
|
||||
* data available from the device. This field should have a non-zero initial
|
||||
* value and decrease as migration data is read from the device.
|
||||
* It is recommended to leave PRE_COPY for STOP_COPY only after this field
|
||||
* reaches zero. Leaving PRE_COPY earlier might make things slower.
|
||||
*
|
||||
* The dirty_bytes field tracks device state changes relative to data
|
||||
* previously retrieved. This field starts at zero and may increase as
|
||||
* the internal device state is modified or decrease as that modified
|
||||
* state is read from the device.
|
||||
*
|
||||
* Userspace may use the combination of these fields to estimate the
|
||||
* potential data size available during the PRE_COPY phases, as well as
|
||||
* trends relative to the rate the device is dirtying its internal
|
||||
* state, but these fields are not required to have any bearing relative
|
||||
* to the data size available during the STOP_COPY phase.
|
||||
*
|
||||
* Drivers have a lot of flexibility in when and what they transfer during the
|
||||
* PRE_COPY phase, and how they report this from VFIO_MIG_GET_PRECOPY_INFO.
|
||||
*
|
||||
* During pre-copy the migration data FD has a temporary "end of stream" that is
|
||||
* reached when both initial_bytes and dirty_byte are zero. For instance, this
|
||||
* may indicate that the device is idle and not currently dirtying any internal
|
||||
* state. When read() is done on this temporary end of stream the kernel driver
|
||||
* should return ENOMSG from read(). Userspace can wait for more data (which may
|
||||
* never come) by using poll.
|
||||
*
|
||||
* Once in STOP_COPY the migration data FD has a permanent end of stream
|
||||
* signaled in the usual way by read() always returning 0 and poll always
|
||||
* returning readable. ENOMSG may not be returned in STOP_COPY.
|
||||
* Support for this ioctl is mandatory if a driver claims to support
|
||||
* VFIO_MIGRATION_PRE_COPY.
|
||||
*
|
||||
* Return: 0 on success, -1 and errno set on failure.
