drm_gem_shmem_create(9)

📦 version 7.3.1, in nixpkgs unstable

💖 drm_gem_shmem_create(9) 💖

okay so bestie, welcome to the drm_gem_shmem_create page from the Kernel API Manual ✨ this one is short and sweet and honestly kind of a vibe — it's the "make me a shmem GEM object" function, and the way it just does that? iconic.

✨ NAME ✨

drm_gem_shmem_create — allocate an object with the given size 🎀

🌸 SYNOPSIS 🌸

struct drm_gem_shmem_object * drm_gem_shmem_create (struct drm_device
*dev , size_t size );

like yes she's one line of C and she's carrying the whole helper file on her back, no cap 💅

🦋 ARGUMENTS 🦋

  • dev — the DRM device 🖥️ like, the actual graphics device you're doing all this for
  • size — size of the object to allocate 📏 this is how much you're asking for, bestie, choose wisely

💜 DESCRIPTION 💜

This function creates a shmem GEM object. that's it, that's the whole description, and honestly? she ate. short, confident, no notes 🌈

(it's the shmem-flavoured GEM object constructor — the drm_gem_shmem_helper.c crew's whole thing, iykyk 🔥)

⭐ RETURN ⭐

On success you get a struct drm_gem_shmem_object * back 🫶 on failure you get an ERR_PTR-encoded negative error code 😭

fr fr: check it with IS_ERR() before you go dereferencing anything — an ERR_PTR is not a real pointer and touching it is giving "undefined behaviour main character energy" in the worst way 💀

the whole shmem squad, assembled 👑 go read them, they're all lowkey obsessed with each other
