💜 radeon_irq_kms_sw_irq_put(9) 💜

okay so bestie, we're deep in the Kernel API Manual today — this one lives in the radeon_irq_kms_sw_irq_put neighborhood and it's literally the "turn the software interrupt off" girly. no cap, that's the whole vibe. 🎀

✨ NAME ✨

radeon_irq_kms_sw_irq_put — disable software interrupt 🔕

🌸 SYNOPSIS 🌸

void radeon_irq_kms_sw_irq_put (struct radeon_device *rdev , int ring );

like, it returns nothing (void, iconic, unbothered) and it takes exactly two things. that's it. that's the whole function signature. 🫶

🦋 ARGUMENTS 🦋

  • rdev — the radeon device pointer 💖 yep, the actual device, she's the main character here.
  • ring — the ring whose interrupt you want to disable 🌈 you gotta tell her which ring, she's not a mind reader.

🔥 DESCRIPTION 🔥

So what does she do? She disables the software interrupt for a specific ring, and yes, that's on all asics — every single one, no exceptions, we love an inclusive queen 👑.

The software interrupt is generally used to signal a fence on a particular ring. that's the whole point of it, iykyk. ✨

🎀 SEE ALSO 🎀

Kernel file ./drivers/gpu/drm/radeon/radeon_irq_kms.c — go read her, she's right there in the source, bestie 💅

And the whole friend group, fr fr:

💀 reminder bestie: put = disable, get = enable. don't mix them up or you're gonna have a bad time.

and that's the page!! mwah 💋 this one shipped out from ./drivers/gpu/drm/radeon, dated October 2026 — so like, very demure, very future, very cunty of her. go forth and disable those software interrupts, queen. 🧚💜⭐
