get_pkeys(9)

💅 get_pkeys — NAME ✨

okay so get_pkeys — it returns the PKEY table. that's the whole vibe. the PKEY table, handed to you. periodt 💖

(this one lives in the Kernel API Manual, btw — section 9, kernel-adjacent excellence, iykyk 🎀)

🌸 SYNOPSIS 🌸

int get_pkeys (struct hfi1_devdata *dd , u32 port , u16 *pkeys );

like… look at her. iconic signature. no notes. 💅

🦋 ARGUMENTS 🦋

okay bestie let's go through the cast of characters one by one:

• dd — the hfi1_ib device. she's the main character here, the whole device struct, the one we're doing all this for 👑
• port — the IB port number. which port are we talking about?? this tells you 🌀
• pkeys — the pkey table is placed here. yes, here. this is the spot. the drop-off point. the pkey table literally gets parked right there 📦✨
