HXG RETRY(9)

💅 HXG Retry 💅

Kernel API Manual bestie!! This page is literally the HXG Retry moment, and it's giving “short but important.” 🫶✨

The HXG Retry_ message should be used by recipient to indicate that the HXG Request_ message was dropped and it should be resent again. No cap, that's the whole assignment. 💌

The REASON field may be used to provide additional information. Extra context? Iconic. 🎀

Here's the bitfield table energy, translated into list form so nobody has to squint at box-drawing characters — the table has Bits and Description columns:

• ORIGIN — the table's bits cells are 0 and 31, exactly like that.
• Bits 30:28 — TYPE = GUC_HXG_TYPE_NO_RESPONSE_RETRY_.
• Bits 27:0 — REASON — reason for retry.
  • GUC_HXG_RETRY_REASON_UNSPECIFIED = 0.
