drm_atomic_commit_alloc(9)

💅 drm_atomic_commit_alloc — like, the Kernel API Manual, bestie ✨

Okay so real talk, this one is a page from the Kernel API Manual (yes, the kernel has lore too 🎀) and it's about the function drm_atomic_commit_alloc. Buckle up, it's short but it's iconic.

✨ NAME ✨

drm_atomic_commit_alloc — allocate atomic state 🦋

📜 SYNOPSIS 📜

struct drm_atomic_commit * drm_atomic_commit_alloc (struct drm_device *dev );

🫶 ARGUMENTS 🫶

• dev — the DRM device. That's it. That's the whole argument. She's low maintenance, we stan 💖

💫 DESCRIPTION 💫

So what does she do? This allocates an empty atomic state to track updates. Literally that's the whole gig — it hands you a blank little atomic state so you've got somewhere to keep track of your updates. Fresh out the box, no cap 👑

ngl it does exactly one thing and it does it well. Main character energy, honestly 💅

🌈 SEE ALSO 🌈

This is the part where the page just. Keeps. Going. And every single one of these is staying because we do not skip details in this house 🫡 Also peep the kernel file ./drivers/gpu/drm/drm_atomic.c — that's where the magic lives, iykyk.
