AI engine is the acceleration engine provided by Xilinx. These engines provide high compute density for vector-based algorithms, and flexible custom compute and data movement. It has core tiles for compute and shim tiles to interface the FPGA fabric.
You can check the AI engine architecture document for more hardware details: https://www.xilinx.com/support/documentation/architecture-manuals/am009-vers...
This patch series adds a Linux kernel driver to manage the Xilinx AI engine array device and AI engine partitions (groups of AI engine tiles dedicated to an application).
v3: * unlock AIE dev mutex after failed to gain the partition lock in errors handing * replace pointer with __u64 and enum with __u32 in ioctl
v2: * Fix dtschema check errors * Fix test bot warning on interrupt implementation. Removed set but unused varaible. * Fix compilation unused function warning of firmware change in case ZynqMP firmware is not configured * There are other warning on ZynqMP firmware reported from testbot which is not introduced by this patch set. "[PATCH] firmware: xlnx-zynqmp: fix compilation warning" is submitted for those fixes.
