[PATCH v2 00/38] cxlflash: OCXL transport support

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

 



This patch series adds OCXL support to the cxlflash driver. With this
support, new devices using the OCXL transport will be supported by the
cxlflash driver along with the existing CXL devices. An effort is made
to keep this transport specific function independent of the existing
core driver that communicates with the AFU.

The first three patches contain a minor fix and staging improvements.

This series is intended for 4.17 and is bisectable.
