Detailed Description

struct fsl_hv_ioctl_memcpy - copy memory between partitions : return error code from the hypervisor : the partition ID of the source partition, or -1 for this partition : the partition ID of the target partition, or -1 for this partition : reserved, must be set to 0 : user-space virtual address of a buffer in the local partition : guest physical address of a buffer in the remote partition : the number of bytes to copy. Both the local and remote buffers must be at least 'count' bytes long

Used by FSL_HV_IOCTL_MEMCPY

The 'local' partition is the partition that calls this ioctl. The 'remote' partition is a different partition. The data is copied from the 'source' paritition' to the 'target' partition.

The buffer in the remote partition must be guest physically contiguous.

This ioctl does not support copying memory between two remote partitions or within the same partition, so either 'source' or 'target' (but not both) must be -1. In other words, either

 source == local and target == remote

or source == remote and target == local
