Subject: Re: [SPDK] Memory buffer allocation in SPDK
Hi James,
Thanks for the info, sounds like we have a way to solve our problem. I have some additional questions. The spdk_mem_register() function, it just adds the region to the SPDK allocation map, right? It does not touch or modifies the memory in any way, right? Is it safe to say that we may register with SPDK all our pre-allocated memory when the application starts and just keep it that way?
Hi Ernest,
Correct – SPDK does not touch the buffer registered with spdk_mem_register() in any way – it only adds it to any registered translation maps.
-Jim
