2018-06-03ocxl: Expose the thread_id needed for wait on POWER9Alastair D'Silva
In order to successfully issue as_notify, an AFU needs to know the TID to notify, which in turn means that this information should be available in userspace so it can be communicated to the AFU.

2018-01-24ocxl: Add a kernel API for other opencapi driversFrederic Barrat
Some of the functions done by the generic driver should also be needed by other opencapi drivers: attaching a context to an adapter, translation fault handling, AFU interrupt allocation... So to avoid code duplication, the driver provides a kernel API that other drivers can use, similar to calling a in-kernel library. It is still a bit theoretical, for lack of real hardware, and will likely need adjustements down the road. But we used the cxlflash driver as a guinea pig.
