ntb_msg_read_sts(9)

💖 NAME 💖

okay so this is ntb_msg_read_sts — it reads the message registers status, bestie ✨ (and yes, the manual we're chilling in is the Kernel API Manual, section 9, iykyk 💅)

---

🦋 SYNOPSIS 🦋

u64 ntb_msg_read_sts (struct ntb_dev *ntb );

---

🎀 ARGUMENTS 🎀

• ntb — the NTB device context, aka the whole vibe of the hardware you're talking to 🫶

---

🌸 DESCRIPTION 🌸

okay so picture this: you wanna know the status of the message register, right? that's literally the whole job. this function reads it. main character energy, no cap 👑

and here's the cute part — the inbound bits and the outbound bits of the message registers can both be filtered by masks that you go get from ntb_msg_inbits and ntb_msg_outbits. so you grab your masks, you filter your bits, you slay 💅

---

⭐ RETURN ⭐

it hands you back the status bits of the message registers, periodt 🔥
