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: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/29698 Signed-off-by: Tomeu Vizoso <tomeu@xxxxxxxxxxxxxxx> --- Tomeu Vizoso (9): iommu/rockchip: Add compatible for rockchip,rk3588-iommu iommu/rockchip: Attach multiple power domains dt-bindings: mailbox: rockchip,rknn: Add bindings arm64: dts: rockchip: Add nodes for NPU and its MMU to rk3588s arm64: dts: rockchip: Enable the NPU on quartzpro64 accel/rocket: Add a new driver for Rockchip's NPU accel/rocket: Add IOCTL for BO creation accel/rocket: Add job submission IOCTL accel/rocket: Add IOCTLs for synchronizing memory accesses .../devicetree/bindings/npu/rockchip,rknn.yaml | 123 + MAINTAINERS | 8 + .../arm64/boot/dts/rockchip/rk3588-quartzpro64.dts | 8 + arch/arm64/boot/dts/rockchip/rk3588s.dtsi | 53 + drivers/accel/Kconfig | 1 + drivers/accel/Makefile | 1 + drivers/accel/rocket/Kconfig | 13 + drivers/accel/rocket/Makefile | 10 + drivers/accel/rocket/rocket_core.c | 155 + drivers/accel/rocket/rocket_core.h | 48 + drivers/accel/rocket/rocket_device.c | 39 + drivers/accel/rocket/rocket_device.h | 40 + drivers/accel/rocket/rocket_drv.c | 243 ++ drivers/accel/rocket/rocket_drv.h | 16 + drivers/accel/rocket/rocket_gem.c | 136 + drivers/accel/rocket/rocket_gem.h | 33 + drivers/accel/rocket/rocket_job.c | 708 ++++ drivers/accel/rocket/rocket_job.h | 49 + drivers/accel/rocket/rocket_registers.h | 4449 ++++++++++++++++++++ drivers/iommu/rockchip-iommu.c | 39 + include/uapi/drm/rocket_accel.h | 116 + 21 files changed, 6288 insertions(+) --- base-commit: 83a7eefedc9b56fe7bfeff13b6c7356688ffa670 change-id: 20240612-6-10-rocket-9316defc14c7 Best regards, -- Tomeu Vizoso <tomeu@xxxxxxxxxxxxxxx>
