dprtc_set_irq_enable(9)

📦 version 7.3.1, in nixpkgs unstable

💖 dprtc_set_irq_enable — a Kernel API Manual moment ✨

okay bestie, buckle up, because we're getting into dprtc_set_irq_enable from the Kernel API Manual (section 9, driver land, the cute place) 🎀 and yes this is the one that flips the big overall interrupt switch, no cap.

✨ NAME ✨

dprtc_set_irq_enable — Set overall interrupt state. 🦋

🌸 SYNOPSIS 🌸

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

so it returns an int, and it takes five whole arguments. five. she's high maintenance and we love that for her 💅

🎀 ARGUMENTS 🎀

  • mc_io — Pointer to MC portal's I/O object. literally the doorway, the portal, the main character of your I/O setup 🔥
  • cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_' (yes, one or more, pick however many you need, no gatekeeping)
  • token — Token of DPRTC object. your lil VIP pass for this DPRTC object 🎟️
  • irq_index — The interrupt index to configure. which interrupt are we talking about, bestie, tell her which one 🫶
  • en — Interrupt state - enable = 1, disable = 0. that's it. one or zero. binary icon behavior ⭐

💀 DESCRIPTION 💀

okay so the whole vibe: this lets GPP software control when interrupts are generated. yes, GPP software, that's you, you're the software, you're in control, main character energy 😌

Each interrupt can have up to 32 causes. thirty-two. that's a lot of causes and honestly same, I have 32 causes too 😭

The enable/disable control's the overall interrupt state. so it's not messing with individual causes, it's the whole big picture, the group chat admin setting 🌈

and here's the important part, bestie: if the interrupt is disabled, no causes will cause an interrupt. like, none. zero. the causes are there, they're just not going to cause anything. that's the whole point. fr fr 💀

💅 RETURN 💅

there's nothing listed here. the section exists and it is empty. she said "no thoughts, head empty" 🙈 so don't come asking me for a return value list, because the manpage didn't give me one and I refuse to invent lore ✋
