pvrdma_query_pkey(9)

🌸 NAME 🌸

okay so bestie, this is the pvrdma_query_pkey(9) page from the Kernel API Manual ✨ and it’s giving very specific kernel energy: pvrdma_query_pkey does exactly one thing — query device port's P_Key table. periodt. 💅

---

✨ SYNOPSIS ✨

the signature, copied exactly and looking iconic:

int pvrdma_query_pkey (struct ib_device *ibdev , u32 port , u16 index ,
       u16 *pkey );

---

🎀 ARGUMENTS 🎀

• ibdev — the device to query. this is the main character device you’re asking about 🫶
• port — the port number. which port, no cap.
• index — the index. the exact index slot, fr fr.
• pkey — the device P_Key value. the P_Key value lands here 💖

---

💖 RETURN 💖

0 on success, otherwise negative errno. that’s the whole vibe check 😭✅
