ctucan_interrupt(9)

✨ NAME ✨

ctucan_interrupt — CAN Isr 💅

okay so this is the ctucan_interrupt(9) page from the Kernel API Manual, and it's literally all about the CTU CAN FD interrupt service routine. bestie, it's giving “interrupt traffic cop” energy 🫶.

🌸 SYNOPSIS 🌸

irqreturn_t ctucan_interrupt (int irq , void *dev_id );

🎀 ARGUMENTS 🎀

• irq — the irq number. iconic.
• dev_id — a pointer to the device id.

💖 DESCRIPTION 💖

This is the CTU CAN FD ISR. It does a little vibe check on the type of interrupt and invokes the corresponding ISR. no cap, that's the whole move ✨.

🔥 RETURN 🔥

• IRQ_NONE — if the CAN device is in sleep mode 😴
• IRQ_HANDLED — otherwise 👑
