xe_preempt_fence_link(9)

💅 xe_preempt_fence_link 💅

okay so this is a page from the Kernel API Manual, section 9, and it's genuinely such a tiny little function but she's important, so let's get into it 🎀

✨ NAME ✨

xe_preempt_fence_link — returns a link that you use to keep unarmed preempt fences on a list 🦋

🌸 SYNOPSIS 🌸

struct list_head * xe_preempt_fence_link (struct xe_preempt_fence
*pfence );

🫶 ARGUMENTS 🫶

• pfence — pointer to the preempt fence, bestie. that's it, that's the whole vibe check ✨

💖 DESCRIPTION 💖

so the link? it's embedded right there in the struct xe_preempt_fence. like, it lives inside it, no cap 💅

when you wanna get back to the preempt fence, you use link_to_preempt_fence to convert back. that's the whole trick, iykyk 🔥

👑 RETURN 👑

it gives you back a pointer to an embedded struct list_head, periodt 💜

🧚 SEE ALSO 🧚

• Kernel file ./drivers/gpu/drm/xe/xe_preempt_fence.h
• to_preempt_fence_from_link(9)

ngl bestie, if you're holding a raw struct list_head * and you don't convert it back with link_to_preempt_fence, you're lowkey just lost in the sauce 😭 use the helper, she exists for a reason 🙈
