okay so bestie, welcome to the Kernel API Manual ✨ — yes this is a real man page, yes it's about the DPIO interrupt coalescing knob, and yes we're gonna get through it together 🫶

🎀 NAME 🎀

dpaa2_io_set_irq_coalescing — the one that sets your brand new IRQ coalescing values 💅

⭐ SYNOPSIS ⭐

int dpaa2_io_set_irq_coalescing (struct dpaa2_io *d , u32 irq_holdoff );

like, that's the whole signature, no cap 🔥

🌸 ARGUMENTS 🌸

  • d — the given DPIO object 👑 this is your main character, the DPIO you're tweaking
  • irq_holdoff — interrupt holdoff (timeout) period in us ⏱️ literally the timeout window, measured in microseconds

🦋 DESCRIPTION 🦋

So what does it actually do? It returns 0 for success, or a negative error code on error. That's it. That's the whole vibe check 😭

ngl bestie, always check that return value — a negative error code is not the slay you're looking for 🙈

🌈 SEE ALSO 🌈

okay this list is long but we're not skipping a single one, periodt 💜 the kernel file lives at ./drivers/soc/fsl/dpio/dpio-service.c ✨

and that's the whole page, bestie 🍓 mwah 💋 — brought to you by the source tree at ./drivers/soc/fsl/dpio, dated October 2026, and the manual page dpaa2_io_set_irq_coalescing(9) herself 👑 go forth and coalesce those interrupts 💖✨
