ntb_set_ctx(9)

💅 ntb_set_ctx(9) 💅

okay so bestie, welcome to the Kernel API Manual page for ntb_set_ctx — she's a lil function but she's important, so pay attention 🎀

---

✨ NAME ✨

ntb_set_ctx — the way you associate a driver context with an ntb device 🫶

---

🌸 SYNOPSIS 🌸

int ntb_set_ctx (struct ntb_dev *ntb , void *ctx , const struct
ntb_ctx_ops *ctx_ops );

---

🦋 ARGUMENTS 🦋

• ntb — the NTB device context. like, the actual device you're working with, mwah 💖
• ctx — the driver context. your stuff, your vibes.
• ctx_ops — the driver context operations. the functions that go with it ✨

---

💜 DESCRIPTION 💜

So what she does is literally this: she associates a driver context and its operations with an ntb device. The context comes from the client driver, and no cap — the driver is allowed to associate a different context with each ntb device. Lowkey flexible. Iconic. 💅

---

🌈 RETURN 🌈

Zero if the context is associated. Otherwise you get an error number 😭 (not the slay outcome, but ok, it happens).
