Signed-off-by: Thanos Makatos <thanos.makatos@nutanix.com>
2020-12-14return region capabilities a la VFIO (#187)Thanos Makatos1-44/+59
This patch returns region capabilities the same way VFIO does: if argsz is not large enough then it returns only region info and sets argsz to what it should be in order to fit the capabilities, the client then retries with a large enough argsz. The protocol specification has been updated as well. Plus unit tests. Signed-off-by: Thanos Makatos <thanos.makatos@nutanix.com>

2020-11-27rename to libvfio-user (#128)John Levon1-78/+79
The muser name no longer reflects the implementation, and will just serve to confuse. Bite the bullet now, and rename ourselves to reflect the actual implementation.

2020-11-18implement new negotiation implementationJohn Levon1-24/+94
Refactor for a partial re-implementation of initial vfio-user negotiation. Still needs to do the JSON parsing - in the meantime, hard-code the max_fds parameters we expect.
2020-11-18implement migration resuming on destination serverThanos Makatos1-61/+219
This patch implements resuming on the destination server. We also demonstrate how to do this in the client/server sample. Signed-off-by: Thanos Makatos <thanos.makatos@nutanix.com>

2020-10-29support for live migration region and dirty page loggingThanos Makatos1-59/+193
This patch adds support for the live migration region and dirty page logging following VFIO. Live migration is NOT yet functional as handling accesses to the migration region is not yet implemented. Currenty the live migration region is fixed at index 9 simply for simplifying the implementation. Dirty page logging is simplified by requiring IOVA ranges to match exactly the entire IOVA range.

2020-10-22samples/client: move VFIO_USER_REGION_READ/VFIO_USER_REGION_WRITE earlierThanos Makatos1-12/+12
It's better to have this test earlier in the code, before we have to manually trigger an IRQ, so that we can catch developement errors more easily. Signed-off-by: Thanos Makatos <thanos.makatos@nutanix.com>
