tsi721_request_msix(9)

💅 tsi721_request_msix — NAME ✨

ok so this is the tsi721_request_msix page from the Kernel API Manual, and it's literally about one thing: registering the interrupt service for MSI-X mode 🎀

tsi721_request_msix — register interrupt service for MSI-X mode. that's it, that's the vibe 💖

---

🫶 SYNOPSIS

int tsi721_request_msix (struct tsi721_device *priv );

---

🌸 ARGUMENTS

• priv — the tsi721 device-specific data structure 👑 like, the whole personality of the device lives in here.

---

⭐ DESCRIPTION

okay bestie so what this does is it registers the MSI-X interrupt service routines — but only for the interrupts that are already active immediately after mport initialization ✨

and here's the part you can't skip: the messaging interrupt service routines? those should be registered during the corresponding open requests, not here 🙈 so don't be out here registering everything in one spot, it's giving chaotic. match the registration to the moment, periodt 💅

---

🔥 RETURN

0 on success, or a -errno value on failure 😭 (iykyk, negative errno is the classic "nope" signature)
