💅 dprc_clear_irq_status — a Kernel API Manual moment

okay so bestie, welcome to dprc_clear_irq_status(9), straight out of the Kernel API Manual ✨ this one's short, sweet, and honestly kind of iconic — it's the "you can stop yelling now" button for interrupts 🎀

✨ NAME ✨

dprc_clear_irq_status — clear a pending interrupt's status 💅

🌸 SYNOPSIS 🌸

int dprc_clear_irq_status (struct fsl_mc_io *mc_io , u32 cmd_flags , u16
token , u8 irq_index , u32 status );

that's it, that's the whole vibe check — five args, one int back 🫶

🦋 ARGUMENTS 🦋

  • mc_io — pointer to the MC portal's I/O object. yes, the portal. the main character energy of the whole call 🌈
  • cmd_flags — command flags, bb — one or more of 'MC_CMD_FLAG_' ⭐ (the manpage literally says "one or more of 'MC_CMD_FLAG_'", so that's what you get, no cap)
  • token — the token of the DPRC object 🔑
  • irq_index — the interrupt index you wanna configure 🎯
  • status — the bits to clear, and it's W1C (write-one-to-clear, iykyk) — one bit per cause:
    • 0 = don't change 🙈
    • 1 = clear that status bit 💀✨
lowkey important: this is write-one-to-clear, so writing a 0 changes nothing. don't be out here thinking a zero does something. it does not. 🫶

👑 RETURN 👑

...yeah. the original page lists the section and then says literally nothing else 😭 so there's nothing to tell you bestie, that's the whole thing. no described return value on this page, periodt.
