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.
