Hi all,
We are porting Steven Smith's para drivers for full-VM to IPF.
In the xen-unstable.hg, a part of the patch was applied.
[overview of pv-on-hvm(rev9) status]
* for only x86 code.
+ 01.early_map_shared.diff: applied (cs:10973)
- Move the mapping of the shared IO page slightly earlier
* common code
+ 06.copy_grant_refs.diff: applied (cs:11058)
- Add a new type of grant copy operation.
+ 07.netback_tidyup.diff: applied (cs:11078)
- Tidy up and remove communications via references to global
structures.
+ 11.add_hvm_h.diff: applied (cs:11080)
- Add a header file with wrappers for hvm_op hypercall.
+ 15.xenbus_no_start_info.diff: applied (cs:11083)
- Avoid direct use of xen_start_info. It's unevailable when
* need to catchup for IPF
+ 02.ioemu_xen_evtchns.diff: applied (cs:10974-10976) *not yet*
- Flip the device model over to using the new Xen event channels
+ 04.hvm_inter.diff: applied (cs:11057)
- Add support for sending event channel interrupts to HVM guests.
+ 10.hvm_op_hypercall.diff: applied (cs:11079)
- Add stubs to Linux for the new hvm_op hypercall.
+ 12.add_maddr_h.diff: applied (cs:11081) *not yet*
- Split useful bits of page.h into new header maddr.h.
+ **hvm_op fixup**: applied (cs:11070)
- HVMOP_get_param return parameter value within the provided
parameter struct
We want to catch up this common feature. We don't complete to catch
up, yet. But I'll post patches which we wrote already.
This patch includes:
* catch up `hvm_op fixup'
- This patch modifies HYPERVISOR_hvm_op().
* catch up `hvm_inter'
- This patch adds support for sending event channel interrupts
to VT-i guests.
* catch up `hvm_op_hypercall'
- This patch includes HYPERVISOR_hvm_op() stabs for linux.
We'll catch up other features, as soon as possible.
Thanks,
- Tsunehisa Doi
