[PATCH 0/8] NVME support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Everyone:

This series contains all of the changes I made in order to add support
for NVME storage in Barebox. Majority of the code was adapted directly
from Linux kernel and I tried to keep it as close to the original as
possible. Only a very basic featureset was implemented:

    - For obvious reason all of the request both to admin and I/O
      queue are fully blocking/syncronous, so none of the I/O
      operations are done in parallel

    - PRP list only DMA (no SGL lists support)

    - No support for shared namespaces

    - No support for transports other than PCIe. All of the pluming to
      add support for it should be there, however.

    - Host memory buffer support is not implemented

Feedback is welcome!

Thanks,
Andrey Smirnov
