---

🦋 SYNOPSIS 🦋

💜 ARGUMENTS 💜

• chan — the mailbox channel 💅 like, the actual channel you're pulling vibes from.
• priv — a pointer to store the private data of mailbox channel. this is where the tea gets written, bestie.

🔥 DESCRIPTION 🔥

okay so picture this: while generating the GCE instruction to command buffer, the private data of GCE hardware may need to be referenced — things like the shift bits of physical address. iykyk. 🫶

so this function is your girl for grabbing that private data out of the mailbox channel. no cap.

the one rule: this function should be called before generating the GCE instruction. literally do it first. don't be that person. 😭
