🎀 __drm_atomic...estroy_state(9) 🎀

okay bestie, welcome to the Kernel API Manual — this one is about a little cleanup function and it's genuinely so important, so let's get into it 💅

✨ NAME ✨

__drm_atomic_helper_crtc_destroy_state — release CRTC state 🧹

🌸 SYNOPSIS 🌸

void __drm_atomic_helper_crtc_destroy_state (struct drm_crtc_state
*state );

like, that's the whole signature. short and iconic, as she should be ✨

🦋 ARGUMENTS 🦋

  • state — the CRTC state object to release 🎀 aka the thing you're saying bye to

💖 DESCRIPTION 💖

so here's the vibe: this function releases all resources stored in the CRTC state — but, and this is the key part, without actually freeing the memory of the CRTC state itself. ngl that distinction is everything 💀

it's useful for drivers that subclass the CRTC state, iykyk. like, if you've got your own fancy extended struct wrapping the CRTC state, this lets you clean out the innards without yeeting the whole allocation out of existence. main character energy for the teardown path, truly 👑

fr fr, remember: resources go poof, the memory stays put. don't mix those two up 🙈
