GUC RELAY DEBUG ACTIONS(9)

🧚 GuC Relay Debug Actions 💅

okay so this page is from the Kernel API Manual (section 9), and it's giving very specific debug-zone energy. 🫶

⚠️ vibe check, bestie: this range of action codes is reserved for debugging purposes only and should be used only on debug builds. These actions may not be supported by the production drivers. Their definitions could be changed in the future. fr fr, read that twice. 💀

The action codes in this range are:

• GUC_RELAY_ACTION_DEBUG_ONLY_START = 0xDEB0
• GUC_RELAY_ACTION_DEBUG_ONLY_END = 0xDEFF

They're bookends, bestie: start at 0xDEB0, end at 0xDEFF. ✨
