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:
* RK3588Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
