zynqmp_ipi_peek_data(9)

💖 zynqmp_ipi_peek_data(9) — a peek, but make it kernel 💖

okay bestie, welcome to the Kernel API Manual entry for zynqmp_ipi_peek_data(9) — yes that's a real function and yes it's living in the kernel, we love a low-level main character 🎀

---

✨ NAME ✨

zynqmp_ipi_peek_data — peek to see if there are any rx messages 👀

Like, that's it. That's the whole vibe. You're literally just looking. No consuming, no stealing, just a respectful little glance to check if anything's waiting in the rx queue 📬

---

🌸 SYNOPSIS 🌸

bool zynqmp_ipi_peek_data (struct mbox_chan *chan );

so she takes one argument and hands you back a bool. simple. iconic. no notes 💅

---

🦋 ARGUMENTS 🦋

• chan — Channel Pointer. literally just the pointer to the channel you're peeking at 🫶

---

💀 RETURN 💀

bestie… the RETURN section is genuinely empty in the source 😭 not me checking twice. There's nothing documented here, so I'm not gonna sit here and make something up — no invented claims on my watch, periodt. If you need the actual return semantics, go read the code (it's a bool, make of that what you will 👀).

fr fr though: don't let anyone (including me) tell you what this returns beyond what's written here, because what's written here is… nothing 🙈
