| accel/rocket Rockchip NPU driver |
| ===================================== |
| |
| The accel/rocket driver supports the Neural Processing Units (NPUs) inside some |
| Rockchip SoCs such as the RK3588. Rockchip calls it RKNN and sometimes RKNPU. |
| |
| The hardware is described in chapter 36 in the RK3588 TRM. |
| |
| This driver just powers the hardware on and off, allocates and maps buffers to |
| the device and submits jobs to the frontend unit. Everything else is done in |
| userspace, as a Gallium driver (also called rocket) that is part of the Mesa3D |
| project. |
| |
| Hardware currently supported: |

| * RK3588 |
