I will post patches for PV-on-HVM on ia64 platform. These patches
modify common code for PV-on-HVM on IPF.
We ported PV-on-HVM for IPF under this consideration:
* Expand memory_op hypercall
+ Introduce XENMEM_add_to_physmap
- A virtual space allocated on HVM-guest OS is remapped original
shared_info and grant_table page with this hypercall.
- This method is same as x86 method.
* Reduce hvm_op hypercall
+ Delete functions introduced for old PV-on-HVM on IPF.
* Revert domain destroy logic
+ revert arch_domain_destroy() for old PV-on-HVM on IPF.
* Modify unmodified_drivers initialization
+ cut off unused codes for IPF
+ modify build rule for IPF
These patch include: (common code)
* unmodified-driver.patch
- unmodified_drivers modification for IPF
* unmodified-build.patch
- unmodified_drivers build rule modification for IPF
We have tested that this patch doesn't affect dom0, domVTi without
pv-on-hvm driver attaching, and domVTi using pv-on-hvm driver works
VBD/VNIF on IPF.
Thanks,
- Tsunehisa Doi
