iommu_group_put(9)

📦 version 7.3.1, in nixpkgs unstable

💅 iommu_group_put(9) — like, the Kernel API Manual page you didn't know you needed

okay so real talk, bestie: this is a page from the Kernel API Manual, section 9, and its whole name is iommu_group_put(9). Say it with me. Slay. Now let's get into it 💖

✨ NAME ✨

iommu_group_put — decrement group reference 🎀

Like, that's it. That's the whole vibe. You're letting go, not grabbing. If you came here to take a reference, you want a different page (we'll link it, don't worry).

🦋 SYNOPSIS 🦋

void iommu_group_put (struct iommu_group *group );

that's the whole signature, no cap. returns void, so don't go checking for an error code, there isn't one 😭

🌸 ARGUMENTS 🌸

  • group — the group to use 🫶 like, the struct iommu_group * you're handing over so it can get its reference count knocked down a peg.

💜 DESCRIPTION 💜

okay so here's the tea ☕ — this function is called by iommu drivers and users to release the iommu group. you're the one dropping your reference, bestie, and that's a healthy thing to do. growth.

and the important part: once the reference count hits zero, the group is released. periodt. that's the whole lifecycle. last one out turns off the lights 💀

🔥 SEE ALSO 🔥

the kernel file lives at ./drivers/iommu/iommu.c — and it has sooo many friends, honestly iconic of it:

iykyk 👑

heads up bestie 🫶 this is a put, not a get. if you drop more references than you took, that's on you, and the kernel will absolutely let you find out 💀

k bye, this page came from the source dir ./drivers/iommu, dated October 2026, and it's respectfully yours from the Kernel API Manual. go forth and release your references responsibly, mwah 💅✨🌸
