dpni_set_irq_enable(9)

💅 dpni_set_irq_enable(9) — it's giving "Set overall interrupt state"

okay so welcome to the Kernel API Manual bestie, and buckle up because we're talking about dpni_set_irq_enable — the function that decides whether your interrupt is even allowed to show up to the party 🎀

---

✨ SYNOPSIS ✨

int dpni_set_irq_enable (struct fsl_mc_io *mc_io , u32 cmd_flags , u16
token , u8 irq_index , u8 en );

---

🦋 ARGUMENTS 🦋

• mc_io — pointer to the MC portal's I/O object. like, the portal. the vibe conduit. 🫶
• cmd_flags — command flags; one or more of MC_CMD_FLAG_
• token — the token of the DPNI object, iykyk 👑
• irq_index — the interrupt index you're configuring
• en — interrupt state: - enable = 1, disable = 0 ⭐

---

🌸 DESCRIPTION 🌸

So here's the tea: this lets GPP software control when interrupts are generated. Each interrupt can have up to 32 causes. The enable/disable control's the overall interrupt state. if the interrupt is disabled no causes will cause an interrupt. periodt 💀

Like — literally, if you flip this off, none of those 32 causes can get a word in. main character energy only when it's enabled, fr fr.

---

💀 RETURN 💀

not me reading this section and finding it completely blank 😭 the original literally documents no return value here — no exit status, no error codes, nothing. so we're not gonna invent one, bestie, that would be lying and lying is not iconic.
