habanalabs: move driver to accel subsystem 2023-01-26T09:52:10+00:00 Oded Gabbay ogabbay@kernel.org 2022-12-26T21:05:00+00:00 e65e175b07bef5974045cc42238de99057669ca7 Now that we have a subsystem for compute accelerators, move the habanalabs driver to it. This patch only moves the files and fixes the Makefiles. Future patches will change the existing code to register to the accel subsystem and expose the accel device char files instead of the habanalabs device char files. Update the MAINTAINERS file to reflect this change. Signed-off-by: Oded Gabbay <ogabbay@kernel.org> 
Now that we have a subsystem for compute accelerators, move the
habanalabs driver to it.

This patch only moves the files and fixes the Makefiles. Future
patches will change the existing code to register to the accel
subsystem and expose the accel device char files instead of the
habanalabs device char files.

Update the MAINTAINERS file to reflect this change.

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
