Thanks, Paul.
So I suppose the only place we need change for this patch is
for hvmmem_type_t, which should be defined like this?
typedef enum {
HVMMEM_ram_rw, /* Normal read/write guest RAM */
HVMMEM_ram_ro, /* Read-only; writes are discarded */
HVMMEM_mmio_dm, /* Reads and write go to the device model */
#if __XEN_INTERFACE_VERSION__ >= 0x00040700
HVMMEM_ioreq_server
#else
HVMMEM_mmio_write_dm
#endif
} hvmmem_type_t;
Besides, does 4.7 still accept freeze exception? It would be great
if we can get an approval for this.
Thanks
Yu
