...r to declare them in an header file rather than locally. The question is in which header file. Thank you for any suggestion. The do_* functions are at least: extern long do_ni_hypercall(void); extern long do_dom0_op(dom0_op_t *u_dom0_op); extern long do_memory_op(int cmd, void *arg); extern long do_multicall(multicall_entry_t *call_list, unsigned int nr_calls); extern long do_event_channel_op(evtchn_op_t *uop); extern long do_xen_version(int cmd, void *arg); extern long do_console_io(int cmd, int count, char *buffer); extern long do_grant_table_op(unsigned int cmd, void *uop, unsigned int count); Tha...

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
