- Strip the perf-trace debug instrumentation (dbg_* counters + HWSUB/rkopnu-trace dev_err); it served its purpose (proved the drm_sched glue is ~3% of a submit). No functional change. - README.md: full build+setup guide (kernel requirements, DT enablement, rocket blacklist, out-of-tree build, librknnrt + rk-llama.cpp rknpu2 userspace, perf notes, limitations). - dt/rk3588-npu-enable.dtso: the necessary DT patch -- mainline ships the RKNN cores + IOMMUs status=disabled; this enables them + OPP table (example board: CoolPi CM5 GenBook; supplies are board-specific). - config/rkopnu.config: kernel config fragment (DRM_ACCEL etc.). - LICENSE: GPL-2.0. A third party can now recreate the mainline-NPU stack from this repo alone.
