adf_send_vf2pf_msg(9)

💌 NAME

adf_send_vf2pf_msg — bestie, this is the "send VF to PF message" girlie ✨

So like, we're in the Kernel API Manual (section 9, kernel-land, very demure, very mindful) and this function is literally just the VF sliding into the PF's DMs 🫶

---

✨ SYNOPSIS ✨

int adf_send_vf2pf_msg (struct adf_accel_dev *accel_dev , struct
pfvf_message msg );

That's the whole fit — one return type, two params, no cap 💅

---

🎀 ARGUMENTS 🎀

• accel_dev — Pointer to acceleration device 💖 the actual device bestie, like the whole reason we're here
• msg — Message to send 🌸 the actual lil payload you're yeeting over to the PF

---

🦋 DESCRIPTION 🦋

Okay so real talk: this function allows the VF to send a message to the PF. That's it, that's the vibe 😭

VF = the one sending. PF = the one receiving. This function = the middlewoman making it happen. Iconic, honestly 👑

---

⭐ RETURN ⭐

0 on success, error code otherwise. So like, if you get a 0 you ate 💅 and if you don't… well. Not me getting a nonzero return 🙈
