HXG RESPONSE(9)

💖 HXG Response(9) 💖

okay bestie, this page is from the Kernel API Manual, and it's giving HXG Response(9) main-character energy. The HXG Response message shall be used as a reply to the HXG Request message that was successfully processed without an error. slay ✨

🌸 message layout / bits & description 🌸

the bit tea is literally this:

• word 0
  • bit 31 — ORIGIN
  • bits 30:28 — TYPE = GUC_HXG_TYPE_RESPONSE_SUCCESS_
  • bits 27:0 — DATA0 — data (depends on ACTION from HXG Request)
• word 1 through word n
  • bits 31:0 — DATAn — data (depends on ACTION from HXG Request)

no cap, that's the whole layout vibe 🫶
