[dpdk-dev] [PATCH 0/6] NXP DPAA2: Refactor bus scan/probe code

[Shreyansh Jain]

In [1], during the IOVA Mapping patch set [2] discussion, it was
observed that DPAA2 scan was actually doing work meant for probing.

This patchset demarcates the roles of FSLMC bus scan and probe
functions much more clearly than before:

1. scan now only add devices into a list
 unlike previously, scan doesn't initialize the devices using the VFIO
 operations. Now, scan would only add the devices onto a local device
 list after marking their type and filling in device name.

2. probe would now perform VFIO operations
 in dpaa2, for the device added in list, an initialization needs
 to be done so as to enable the devices - before actually API calls
 can be served. Probe function now initializes the devices as well
 as links then to the Eth/Crypto drivers.

3. Refactoring some VFIO code
 This patch improves the overall code contained within DPAA2 bus
 for DPAA2 VFIO layer.
