Rockchip calls it RKNN and sometimes RKNPU. 9 10The hardware is described in chapter 36 in the RK3588 TRM. 11 12This driver just powers the hardware on and off, allocates and maps buffers to 13the device and submits jobs to the frontend unit. Everything else is done in 14userspace, as a Gallium driver (also called rocket) that is part of the Mesa3D 15project. 16 17Hardware currently supported: 18 19* RK3588 20
