Subject: Proposal to realize hot-add *several sections one time*
Date: Wed, 11 Jun 2014 17:12:33 +0800 [thread overview]
Message-ID: <53981D81.5060708@huawei.com> (raw)
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.
