💅 rvu_npc_exa..._table_write(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, we're being official today 🎀 and today's main character is rvu_npc_exa..._table_write(9), a little wrapper that is genuinely just out here doing register writes. no cap.

---

✨ NAME ✨

rvu_npc_exact_cam_table_write — literally a wrapper for a register write. that's it. that's the whole vibe. 🦋

---

✨ SYNOPSIS ✨

void rvu_npc_exact_cam_table_write (struct rvu *rvu , int blkaddr , u32
index , u64 mdata );

like, look at her. she's void, she takes four things, she writes to a register. iconic behavior only. 👑

---

✨ ARGUMENTS ✨

• rvu — the resource virtualization unit. (yes that's the whole description, she's a mystery but a slay one 💜)
• blkaddr — block address 🧚
• index — the index in MEM 🌸
• mdata — meta data to be written to the register. so like, the actual payload bestie 💌
