So, how can I get the ZONE_DMA real size ? Is there any kernel functions or configuration files ? I want to get the accurate number.

Take a look at the /proc/zoneinfo file in your running kernel. It will tell you where each zone starts ('start_pfn' lines) and how many pages there are ('pages spanned' lines). -- Thanks. -- Max
