File contents

/debug-kernel — Debug an LLK Kernel

Usage

/debug-kernel tt_llk_blackhole/llk_lib/llk_pack_untilize.h
/debug-kernel tt_llk_quasar/common/inc/sfpu/ckernel_sfpu_gelu.h
/debug-kernel  (no args — will ask for the kernel path or check recent test output)

What to Do

  1. Parse the kernel path from the user's arguments. If not provided, check recent test output or ask.
  2. Infer the kernel type from the path:
    • common/inc/sfpu/ → sfpu
    • llk_lib/llk_math_ → math
    • llk_lib/llk_pack_ → pack
    • llk_lib/llk_unpack_ → unpack
  3. Infer the architecture from the path:
    • tt_llk_wormhole_b0/ → wormhole
    • tt_llk_blackhole/ → blackhole
    • tt_llk_quasar/ → quasar
  4. Spawn the llk-debugger agent:
Agent tool:
  subagent_type: "llk-debugger"
  description: "Debug {kernel_name}"
  prompt: |
    Kernel path: {kernel_path}
    Kernel type: {kernel_type}
    Architecture: {architecture}
    Error context: {any error output the user provided, or "check logs"}
  1. Report the agent's results to the user
  2. If the fix involves code changes, show the diff and explain the fix
