Ian,
Thanks for your effort.
A tiny change may be needed but I don't block this.
+libxl__xc_device_get_rdm(libxl__gc *gc,
+ uint32_t flag,
Since now we are sitting on xc_reserved_device_memory_map(, flags, xxx),
s/flag/flags may be better.
+ uint16_t seg,
+ uint8_t bus,
+ uint8_t devfn,
+ unsigned int *nr_entries,
+ struct xen_reserved_device_memory **xrdm)
+{
[snip]
+ r = xc_reserved_device_memory_map(CTX->xch, flag, seg, bus, devfn,
Ditto.
+ NULL, nr_entries);
+ assert(r <= 0);
+ /* "0" means we have no any rdm entry. */
+ if (!r) goto out;
+
+ if (errno != ENOBUFS) {
+ rc = ERROR_FAIL;
+ goto out;
+ }
+
+ GCNEW_ARRAY(*xrdm, *nr_entries);
+ r = xc_reserved_device_memory_map(CTX->xch, flag, seg, bus, devfn,
Ditto.
Thanks
Tiejun
