devm_apertu...tform_device(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

Okay so bestie, this page is all about devm_aperture_acquire_for_platform_device — and what it does is literally acquire ownership of an aperture on behalf of a platform device. That's the whole vibe. Own the aperture. For a platform device. Slay. ✨

This is a page from the Kernel API Manual, and it's giving extremely niche but extremely important. 🎀

🦋 SYNOPSIS 🦋

int devm_aperture_acquire_for_platform_device (struct platform_device
*pdev , resource_size_t base , resource_size_t size );

🌸 ARGUMENTS 🌸

  • pdev — the platform device that gets to own the aperture. Main character energy, honestly. 👑
  • base — the aperture's byte offset in physical memory. Like, where it lives in memory. 📍
  • size — the aperture size in bytes, so you know exactly how much of memory we're talking about. 📏

✨ DESCRIPTION ✨

So what this does is install the given device as the new owner of the aperture. Periodt. 💅

The function expects the aperture to be provided by a platform device — that's just the arrangement, iykyk.

Here's the cute part: if another driver takes over ownership of the aperture, aperture helpers will then unregister the platform device automatically. No manual cleanup, no drama, it just handles it. 🧚 And all acquired apertures are released automatically when the underlying device goes away. Devm really said "I got you" fr fr. 🫶

⚠️ But bestie, listen — the function fails if the aperture, or parts of it, is currently owned by another device. No cap. So if you want to evict the current owners, callers should use remove_conflicting_devices et al. before calling this function. Order matters, okay? 😭

🔥 RETURN 🔥

  • 0 on success 🎉
  • or a negative errno value otherwise 💀
