| * | xen/gntdev: add ioctl for grant copy | David Vrabel | 2016-01-07 |
| | | | | | | | | | | | | | | | | | | | Add IOCTL_GNTDEV_GRANT_COPY to allow applications to copy between user space buffers and grant references. This interface is similar to the GNTTABOP_copy hypercall ABI except the local buffers are provided using a virtual address (instead of a GFN and offset). To avoid userspace from having to page align its buffers the driver will use two or more ops if required. If the ioctl returns 0, the application must check the status of each segment with the segments status field. If the ioctl returns a -ve error code (EINVAL or EFAULT), the status of individual ops is undefined.

| xen/gntdev.h and xen/gntalloc.h both provide userspace ABIs so they should be installed. CC: stable@vger.kernel.org Signed-off-by: David Vrabel <david.vrabel@citrix.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> | |||
