Abstract:
Embodiments generally relate to handling of NVMe scatter gather list bit bucket transfers by a data storage device. The data storage device transfers the data associated with the bit bucket transfers to a host or to a controller memory buffer of the data storage device. The data storage device can transfer the data associated with the bit bucket transfers to the host by modifying transaction layer packets (TLPs) to indicate to the host to ignore the data payload of the TLPs.
