This assumes LP64 architectures, why not using a
Hi Frediano,
I think no assumption is introduced by this patch.
memslot_get_virt returns unsigned long so that's the type
I used for bitmap_virt.
I do not think using void* makes it "safer".
Possibly we can change memslot_get_virt to remove the assumption.
Thanks,
Uri.
void *image_data;
+ bitmap_virt = memslot_get_virt(slots, addr, size, group_id, &error);
here
image_data = (void*)memslot_get_virt(slots, addr, size, group_id, &error);
+ if (error) {
+ return 0;
+ }
data = spice_chunks_new(1);
data->data_size = size;
- data->chunk[0].data = (void*)memslot_get_virt(slots, addr, size,
group_id, &error);
- if (error) {
- return 0;
- }
+ data->chunk[0].data = (void*)bitmap_virt;
here
data->chunk[0].data = image_data;
data->chunk[0].len = size;
return data;
}
This is portable to LLP64 (I know, Linux is always LP64 but it does not
cost much).
