tsi721_imsg_msix(9)

💖 NAME 💖

okay so bestie, welcome to tsi721_imsg_msix(9) from the Kernel API Manual — this is the MSI-X interrupt handler for inbound messaging, and yes, the name is a whole mouthful, but we're slaying it. 💅

✨ SYNOPSIS ✨

irqreturn_t tsi721_imsg_msix (int irq , void *ptr );

🎀 ARGUMENTS 🎀

• irq — the Linux interrupt number, fr.
• ptr — pointer to interrupt-specific data (a tsi721_device structure). iykyk. 🫶

🦋 DESCRIPTION 🦋

It handles inbound messaging interrupts signaled using MSI-X. That's the whole vibe. No cap. ✨

🌸 RETURN 🌸

It returns IRQ_HANDLED. That's it — literally IRQ_HANDLED, and that's iconic. 👑
