v6 changes:
- Check compiler before using [0] or [].
v5 changes:
- Fix prototypes in v4v.h for do_v4v_op
- Add padding to make sure all the structures
are 64 bits aligned
- Replace [0] with []
v4 changes:
- Stop using ssize_t, use long instead
- Return -MSGSIZE for message bigger than 2GB
- Fixup size handling
- Rename protocol with message_type to avoid the
confusion with the IP protocol flag
- Replaced V4V_DOMID_ANY value with DOMID_INVALID
- Replaced v4v_pfn_t with xen_pfn_t
- Add padding to struct v4v_info
- Fixup hypercall documentation
- Move V4V_ROUNDUP to v4v.c
- Remove v4v_utils.h (we could potentially add it later).
v3 changes:
- Switch to event channel
- Allocated a unbound event channel
per domain.
- Add a new v4v call to share the
event channel port.
- Public headers with actual type definition
- Align all the v4v type to 64 bits
- Modify v4v MAGIC numbers because we won't
but backward compatible anymore
- Merge insert and insertv
- Merge send and sendv
- Turn all the lock prerequisite from comment
to ASSERT()
- Make use or write_atomic instead of volatile pointers
- Merge v4v_memcpy_to_guest_ring and
v4v_memcpy_to_guest_ring_from_guest
- Introduce copy_from_guest_maybe that can take
a void * and a handle as src address.
- Replace 6 arguments hypercalls with 5 arguments hypercalls.
v2 changes:
- Cleanup plugin header
- Include basic access control
- Use guest_handle_for_field
Jan Beulich (1):
xen: Introduce guest_handle_for_field
Jean Guyader (3):
xen: virq, remove VIRQ_XC_RESERVED
xen: events, exposes evtchn_alloc_unbound_domain
xen: Add V4V implementation
