okay so bestie, welcome to ib_query_pkey(9), the page that's literally just "get me that P_Key table entry" and honestly? she ate. we're in the Kernel API Manual, this is the whole vibe, let's go 🎀

✨ NAME ✨

ib_query_pkey — Get P_Key table entry 👑

✨ SYNOPSIS ✨

int ib_query_pkey (struct ib_device *device , u32 port_num , u16 index ,
u16 *pkey );

no cap, that's the whole signature. look at her. iconic. 🦋

✨ ARGUMENTS ✨

• device — the Device you're querying, like, the main character here 🫶
• port_num — the Port number you're querying, yes you gotta say which port, be specific bestie
• index — the P_Key table index you're querying, it's giving "which slot tho"
• pkey — the Returned P_Key 💖 (she comes back to you through this pointer, so treat her right)

✨ DESCRIPTION ✨

so ib_query_pkey fetches the specified P_Key table entry. that's it. that's the whole plot. specifical entry, fetched, done. lowkey obsessed with how unbothered this function is 🌸

okay this list is LONG, so buckle up bestie, we're going on a little tour of the Kernel file ./drivers/infiniband/core/device.c and all her friends 🧚
