[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v4 0/6] ARM hypercall ABI: 64 bit ready
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 introduces two new macros to convert XEN_GUEST_HANDLE_PARAM to
XEN_GUEST_HANDLE and vice versa;
- it replaces all the occurrences of XEN_GUEST_HANDLE in hypercall
parameters with XEN_GUEST_HANDLE_PARAM.
On x86 and ia64 things should stay exactly the same.
On ARM all the unsigned long and the guest pointers that are members of
a struct become size 8 byte (both aarch and aarch64).
However guest pointers that are passed as hypercall arguments in
registers are going to be 4 bytes on aarch and 8 bytes on aarch64.
It is based on Ian's arm-for-4.3 branch.
Changes in v4:
- make both XEN_GUEST_HANDLE and XEN_GUEST_HANDLE_PARAM unions on ARM;
- simplify set_xen_guest_handle_raw on ARM;
- add type checking in guest_handle_to_param and guest_handle_from_param
(all architectures).
Changes in v3:
- default all the guest_handle_* conversion macros to
XEN_GUEST_HANDLE_PARAM as return type;
- add two new guest_handle_to_param and guest_handle_from_param macros
to do conversions.
Changes in v2:
- do not use an anonymous union in struct xen_add_to_physmap;
- do not replace the unsigned long in x86 specific calls;
- do not replace the unsigned long in multicall_entry;
- add missing include "xen.h" in version.h;
- use proper printf flag for xen_ulong_t in python/xen/lowlevel/xc/xc;
- add 2 missing #define _XEN_GUEST_HANDLE_PARAM for the compilation of
the compat code;
- add a patch to limit the maximum number of extents handled by
do_memory_op;
- remove the patch "introduce __lshrdi3 and __aeabi_llsr" that is
already in the for-4.3 branch.
Stefano Stabellini (6):
xen: improve changes to xen_add_to_physmap
xen: xen_ulong_t substitution
xen: change the limit of nr_extents to UINT_MAX >> MEMOP_EXTENT_SHIFT
xen: introduce XEN_GUEST_HANDLE_PARAM
xen: replace XEN_GUEST_HANDLE with XEN_GUEST_HANDLE_PARAM when appropriate
xen: more substitutions
