VPU stands for Versatile Processing Unit and it's a CPU-integrated
inference accelerator for Computer Vision and Deep Learning
applications.
The VPU device consist of following components:
- Buttress - provides CPU to VPU integration, interrupt, frequency and
power management.
- Memory Management Unit (based on ARM MMU-600) - translates VPU to
host DMA addresses, isolates user workloads.
- RISC based microcontroller - executes firmware that provides job
execution API for the kernel-mode driver
- Neural Compute Subsystem (NCS) - does the actual work, provides
Compute and Copy engines.
- Network on Chip (NoC) - network fabric connecting all the components
This driver supports VPU IP v2.7 integrated into Intel Meteor Lake
client CPUs (14th generation).
Module sources are at drivers/accel/ivpu and module name is
"intel_vpu.ko".
This patch includes only very besic functionality:
- module, PCI device and IRQ initialization
- register definitions and low level register manipulation functions
- SET/GET_PARAM ioctls
- power up without firmware
