This patch series concerns Xen. Another serie will come for QEMU.
As we discussed on Xen/QEMU mailing list
(http://marc.info/?l=qemu-devel&m=133042969527515), I have worked on multiple
QEMU support for one domain.
QEMU must registered all IO ranges (MMIO and PIO) and PCI that it's want's to
use to allow multiple QEMU.
Each QEMU will handle a subset of the hardware. It will retrieve its
configuration with XenStore.
Both of these patch series (one for Xen, the other Xen) are not complete,
and it breaks some parts of Xen ...
The purpose of these series is to start a discussion on how to implement
multiple ioreq server on Xen and QEMU.
Julien Grall (15):
hvm: Modify interface to support multiple ioreq server
hvm: Add functions to handle ioreq servers
hvm-pci: Handle PCI config space in Xen
hvm: Change initialization/destruction of an hvm
hvm: Modify hvm_op
hvm-io: IO refactoring with ioreq server
hvm-io: send invalidate map cache to each registered servers
hvm-io: Handle server in buffered IO
xc: Add the hypercall for multiple servers
xc: Add argument to allocate more special pages
xc: Fix python build
xl: Add interface to handle multiple device models
xl-qmp: add device model id to qmp function
xl-parsing: Parse the new option device_models
xl: Launch and destroy all device models
