rvu_npc_exa..._table_write(9)

💅 rvu_npc_exa..._table_write(9) — from the Kernel API Manual, bestie 🫶

Okay so welcome to the glow-up edition of the rvu_npc_exa..._table_write(9) page, straight out of the Kernel API Manual. Pull up a chair, grab a strawberry 🍓, and let's get into it.

✨ NAME ✨

rvu_npc_exact_mem_table_write — literally just a wrapper for a register write, no cap. That's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

void rvu_npc_exact_mem_table_write (struct rvu *rvu , int blkaddr , u8
ways , u32 index , u64 mdata );

It returns void, so like… nothing comes back. It just does the thing. 💅

---

🦋 ARGUMENTS 🦋

• rvu — the resource virtualization unit. The main character, honestly. 👑
• blkaddr — block address. Where the block lives, iykyk.
• ways — the ways for the MEM table. Plural, because one way is never enough.
• index — the index in MEM. Think of it as the seat number at the function.
• mdata — the meta data to be written to the register. This is the payload, the moment, the content. ✨

And that's the page, bestie! Big kiss from the source at ./drivers/net/ethernet/marvell..., dated October 2026, under the rvu_npc_exa..._table_write(9) name. Slay, go write some registers. 🌈💖
