I don't know of anything written at this level of detail, in part because the PVA
APIs are more expansive than libca. My recent efforts at documentation of a PVA
client/server APIs can be found at:

The Database APIs (drivers/device support) haven't changed much (yet).
One relevant addition is DBF_INT64/DBF_UINT64 which can be used with
eg. waveformRecord by setting FTVL="INT64".
