Subject: [SPDK] Memory Buffer Allocation in SPDK
Date: Mon, 12 Dec 2016 23:13:09 -0500	[thread overview]
Message-ID: <01acc08b07afdca4b70a587cc00c99dd@cs.fsu.edu> (raw)

Hi All,

Is there any way to directly use the memory allocated by the malloc() 
function? The spdk_malloc() allocates a pinned memory buffer in huge 
page, and the spdk_nvme_ns_cmd_write also uses the pinned memory for 
write. However, if we allocate a memory buffer by malloc(), how could we 
directly write data to NVMe device by SPDK without copying data to the 
buffer allocated by spdk_malloc()?

Thanks,
Yue
