157 * Returns a host pointer to a buffer placed at offset @phys within the
158 * active slot @group_id of the PCI VGA RAM memory region associated with

164 * section and does not hold the iothread lock, it must have other means of
165 * protecting the pointer, such as a reference to the region that includes
166 * the incoming ram_addr_t.
