Hi, Now we can hot-add memory by % echo start_address_of_new_memory > /sys/devices/system/memory/probe Then, [start_address_of_new_memory, start_address_of_new_memory + memory_block_size] memory range is hot-added. But we can only hot-add *one section one time* by this way. Whether we can add an argument on behalf of the count of the sections to add ? So we can can hot-add *several sections one time*. Just like: % echo start_address_of_new_memory count_of_sections > /sys/devices/system/memory/probe Then, [start_address_of_new_memory, start_address_of_new_memory + count_of_sections * memory_block_size] memory range is hot-added. If this proposal is reasonable, i will send a patch to realize it. Any suggestions ? Best regards. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
