Sorry, just noticed that I miss merged one line. Please ignore this V8 set. I will send out V9 instead.

This patchset introduces a new Linux Kernel Driver, amdxdna for AMD NPUs. The driver is based on Linux accel subsystem. NPU (Neural Processing Unit) is an AI inference accelerator integrated into AMD client CPUs. NPU enables efficient execution of Machine Learning applications like CNNs, LLMs, etc. NPU is based on AMD XDNA architecture [1]. AMD NPU consists of the following components: - Tiled array of AMD AI Engine processors. - Micro Controller which runs the NPU Firmware responsible for command processing, AIE array configuration, and execution management. - PCI EP for host control of the NPU device. - Interconnect for connecting the NPU components together. - SRAM for use by the NPU Firmware. - Address translation hardware for protected host memory access by the NPU. NPU supports multiple concurrent fully isolated contexts. Concurrent contexts may be bound to AI Engine array spatially and or temporarily. The driver is licensed under GPL-2.0 except for UAPI header which is licensed GPL-2.0 WITH Linux-syscall-note. User mode driver stack consists of XRT [2] and AMD AIE Plugin for IREE [3]. The firmware for the NPU is distributed as a closed source binary, and has already been pushed to the DRM firmware repository [4].
