Hi all, this patch series makes the necessary changes to make sure that the current ARM hypercall ABI can be used as-is on 64 bit ARM platforms: - it defines xen_ulong_t as uint64_t on ARM; - it introduces a new macro to handle guest pointers, called XEN_GUEST_HANDLE_PARAM (that has size 4 bytes on aarch and is going to have size 8 bytes on aarch64); - it replaces all the occurrences of

Populate-on-demand: Check pages being returned by the balloon driver This patch series is the second result of my work last summer on decreasing fragmentation of superpages in a guests'' p2m when using populate-on-demand. This patch series is against 4.1; I''m posting it to get feedback on the viability of getting a ported version of this patch into 4.2. As with the previous

Changes from v1: - Define new struct hvm_trap to represent information of trap, include instruction length. - Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of wrappers around that function for existing callers, so that their parameter lists actually *shrink*. This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP),

This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP), INTn instruction emulation. Introduce new function vmx_inject_sw_exception() which deliver the software excetion, software interrupt and privileged software exception. Split hardware exception as a seperate function(old function vmx_inject_hw_exception()). Also Passed down intruction length

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.
