dma_fence_lock_irqsave(9)

✨ NAME ✨

Welcome to the dma_fence_lock_irqsave(9) page from the Kernel API Manual, bestie 💖. This one is literally dma_fence_lock_irqsave — irqsave lock the fence. That’s the whole name, no cap. 🎀

✨ SYNOPSIS ✨

dma_fence_lock_irqsave (fence , flags );

Lowkey iconic signature, keep it exactly like that. 💅

✨ ARGUMENTS ✨

• fence — the fence to lock. Yep, that’s the one you’re locking. 🔒
• flags — where to store the CPU flags. Don’t forget, bestie. 🫶

✨ DESCRIPTION ✨

Okay so: lock the fence, preventing it from changing to the signaled state. That’s the entire plot — the fence is not gonna flip to signaled while you’ve got it locked. Highkey the whole point. ✨🔒

It’s giving “do not disturb” for fences, and honestly? Slay. 💅
