[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v18 12/13] x86/hvm: Remove redundant save functions
This patch removes the redundant save functions and renames the
save_one* to save. It then changes the domain param to vcpu in the
save funcs and adapts print messages in order to match the format of the
other save related messages.
Signed-off-by: Alexandru Isaila <aisaila@xxxxxxxxxxxxxxx>
---
Changes since V17:
- Refit HVM_REGISTER_SAVE_RESTORE(CPU)
- Add const to the added struct domain *d
- Changed the instance bound check from hvm_save_one()
- Update ctxt.size for save_one instance.
