Bug Description
== Comment: #0 - Breno Henrique Leitao <email address hidden> - 2017-04-26 15:08:18 ==
Hello,
We would like to include CAPI2 support on the CXL device driver on Zesty kernel.
The coherent accelerator interface is designed to allow the coherent connection of accelerators (FPGAs and other devices) to a POWER system. These devices need to adhere to the Coherent Accelerator Interface Architecture (CAIA).
This PSL Version 9 provides new features such as:
* Interaction with the nest MMU on the P9 chip.
* Native DMA support.
* Supports sending ASB_Notify messages for host thread wakeup.
* Supports Atomic operations.
