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> --- Changes in v2: - Drop patch adding the rk3588 compatible to rockchip-iommu (Sebastian Reichel) - Drop patch adding support for multiple power domains to rockchip-iommu (Sebastian Reichel) - Link to v1: https://lore.kernel.org/r/20240612-6-10-rocket-v1-0-060e48eea250@xxxxxxxxxxxxxxx --- Tomeu Vizoso (7): dt-bindings: npu: 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 Documentation/accel/index.rst | 1 + Documentation/accel/rocket/index.rst | 19 + .../bindings/npu/rockchip,rknn-core.yaml | 152 + MAINTAINERS | 8 + arch/arm64/boot/dts/rockchip/rk3588-base.dtsi | 76 + .../arm64/boot/dts/rockchip/rk3588-quartzpro64.dts | 30 + drivers/accel/Kconfig | 1 + drivers/accel/Makefile | 1 + drivers/accel/rocket/Kconfig | 25 + drivers/accel/rocket/Makefile | 10 + drivers/accel/rocket/rocket_core.c | 77 + drivers/accel/rocket/rocket_core.h | 43 + drivers/accel/rocket/rocket_device.c | 35 + drivers/accel/rocket/rocket_device.h | 33 + drivers/accel/rocket/rocket_drv.c | 295 ++ drivers/accel/rocket/rocket_drv.h | 17 + drivers/accel/rocket/rocket_gem.c | 216 + drivers/accel/rocket/rocket_gem.h | 32 + drivers/accel/rocket/rocket_job.c | 710 ++++ drivers/accel/rocket/rocket_job.h | 50 + drivers/accel/rocket/rocket_registers.h | 4425 ++++++++++++++++++++ include/uapi/drm/rocket_accel.h | 116 + 22 files changed, 6372 insertions(+) --- base-commit: 585e191534efe95712df88a22eaa8d51228bcb43 change-id: 20240612-6-10-rocket-9316defc14c7 Best regards, -- Tomeu Vizoso <tomeu@xxxxxxxxxxxxxxx>
