[PATCH v2 0/7] New DRM accel driver for Rockchip's RKNN NPU

From: Tomeu Vizoso
Date: Tue Feb 25 2025 - 02:56:27 EST


This series adds a new driver for the NPU that Rockchip includes in its
newer SoCs, developed by them on the NVDLA base.

In its current form, it supports the specific NPU in the RK3588 SoC.

The userspace driver is part of Mesa and an initial draft can be found at:
