[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v9 08/13] Add IOREQ_TYPE_VMWARE_PORT
This adds synchronization of the 6 vcpu registers (only 32bits of
them) that vmport.c needs between Xen and QEMU.
This is to avoid a 2nd and 3rd exchange between QEMU and Xen to
fetch and put these 6 vcpu registers used by the code in vmport.c
and vmmouse.c
In the tools, enable usage of QEMU's vmport code.
The currently most useful VMware port support that QEMU has is the
VMware mouse support. Xorg included a VMware mouse support that
uses absolute mode. This make using a mouse in X11 much nicer.
Signed-off-by: Don Slutz <dslutz@xxxxxxxxxxx>

v9:
New code was presented as an RFC before this.
Paul Durrant sugested I add support for other IOREQ types
to HVMOP_map_io_range_to_ioreq_server.
I have done this.
