gasp_walk

Structure with the guest system walking state

Synopsis:

#include <qvm/gasp.h>

struct gasp_walk_state {
    void* span;
    const struct guest_system* gsp;
    uint64_t guest_loc;
    uint64_t host_loc;
    uint64_t length;
    uint64_t max_length;
    unsigned flags;
} ;

Data:

void* span: Private state field.
const struct guest_system* gsp: Guest system pointer.
uint64_t guest_loc: Start address of the region in the guest physical address space.
uint64_t host_loc: Start address of the region in the host physical address space, if present and if it was requested (the GWS_HOST flag is set).
uint64_t length: Length of the region, in bytes.
uint64_t max_length: Maximum allowed length for the region, in bytes.
unsigned flags: Walk flags (GWS_*).

Library:

Provided by qvm; no external library is required.

Description:

This structure records the current state of a guest address walk (see guest_walk_init() and guest_walk_next().) This information is always in the context of the guest address space.
