dpsw_set_irq_enable(9)

💅 dpsw_set_irq_enable — set the overall interrupt state

okay so bestie, you're reading the dpsw_set_irq_enable(9) page from the Kernel API Manual ✨ — this is the one that flips the big master switch for a switch's interrupts. No cap, it's a tiny function with main-character energy 🎀

---

✨ NAME ✨

dpsw_set_irq_enable — Set overall interrupt state. that's it, that's the whole vibe 💅

---

🦋 SYNOPSIS 🦋

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

literally just five args and an int coming back at you, periodt 🌸

---

🎀 ARGUMENTS 🎀

• mc_io — pointer to the MC portal's I/O object. yes, the portal, the whole access point, hand it over 🫶
• cmd_flags — command flags, and you're picking one or more of MC_CMD_FLAG_ 👑
• token — the token of the DPCI object. keep it safe, it's your little ID badge 💖
• irq_index — the interrupt index you wanna configure. which one? that one. 🔥
• en — the interrupt state, and it's giving binary: enable = 1, disable = 0 ⭐

---

🌈 DESCRIPTION 🌈

so this is how GPP software gets to control when interrupts are generated 💫 Each interrupt can have up to 32 causes — like, 32 whole reasons for it to fire, iconic. The enable/disable control is the overall interrupt state, the big boss switch up top 👑

and here's the important part, bestie: if the interrupt is disabled, no causes will cause an interrupt. not one. not any of the 32. zero. the whole thing is off 😭 so flip en with intention, okay?

💀 RETURN 💀

the original page leaves this section completely empty — no return values documented, no explanation, nothing. just vibes and a heading. 🙈 don't come for me, I'm reporting it exactly as it is.
