dprc_set_irq(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dprc_set_irq — yes bestie, we're setting IRQs now

okay so this is a page from the Kernel API Manual, and the star of the show is dprc_set_irq(9). say hi 👋

✨ NAME ✨

dprc_set_irq — literally what it says on the tin: it sets the IRQ information for the DPRC so it can trigger an interrupt. no cap. 💅

🦋 SYNOPSIS 🦋

int dprc_set_irq (struct fsl_mc_io *mc_io , u32 cmd_flags , u16 token ,
                  u8 irq_index , struct dprc_irq_cfg *irq_cfg );

that's the whole signature, and yes she's a int returner, icon behaviour 👑

🎀 ARGUMENTS 🎀

okay so every single one of these matters, so let's go one by one, no skipping:

  • mc_io — pointer to the MC portal's I/O object. it's giving "the doorway to the management complex", and you gotta hand it over 🚪✨
  • cmd_flags — command flags, bestie. one or more of 'MC_CMD_FLAG_'. that's the whole vibe for this one 💫
  • token — the token of the DPRC object. it's the little ID badge that says "yes, this DPRC, not that one" 🎫
  • irq_index — identifies the interrupt index to configure. which interrupt slot are we doing today, hmm? 🤔
  • irq_cfg — the IRQ configuration. this is the actual payload, the main character of the argument list ngl 🌟

💀 RETURN 💀

so… there's genuinely nothing listed here in the original, bestie. the section exists, it's just empty. it's giving "left on read" 😭🙈

fr fr though — nothing was documented for return values on this page, so don't come for me, I'm not inventing anything 💅

🫶 SEE ALSO 🫶

where to go next, the whole friend group:

kernel file ./drivers/bus/fsl-mc/dprc.c

and the squad of related calls:

like, that's the full roster — read them, love them, link them 🧚💜

that's the page!! 🎀 this little beauty lives in ./drivers/bus/fsl-mc and she's dated October 2026. mwah, go configure some interrupts responsibly, bestie 🌈⭐🔥
