ttm_eu_fence_buffer_objects(9)

💅 ttm_eu_fence_buffer_objects(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a whole function and it's lowkey iconic for wrapping up a command submission, so let's get into it 🫶

---

✨ NAME ✨

ttm_eu_fence_buffer_objects — no cap, the original page literally leaves the description blank here, so we're just vibing with the function name itself 💀 (yes, the manpage really did that — that's the tea)

---

🌸 SYNOPSIS 🌸

void ttm_eu_fence_buffer_objects (struct ww_acquire_ctx *ticket ,
                                  struct list_head *list ,
                                  struct dma_fence *fence );

it's giving "three arguments, zero drama" — returns void, so nothing comes back out, she just does the thing ✨

---

🎀 ARGUMENTS 🎀

• ticket — the ww_acquire_ctx that came from the reserve call 👑 like, this is your little proof-of-reservation receipt, don't lose it
• list — a thread-private list of ttm_validate_buffer structs 📋 (thread private = just for this thread, iykyk)
• fence — the brand new exclusive fence for the buffers 🔥 this is the fresh sync object she's about to hand out

---

🦋 DESCRIPTION 🦋

okay so the vibe check here: you call this function when your command submission is complete ✅ like, done done, no more work to submit.

what she does is chef's kiss:

• she adds a new sync object to the bos pointed to by the entries on list 🎁
• she also unreserves all the buffers, putting them on lru lists 🌈

literally the cleanup bestie — you finish submitting, she fences the buffers and frees them from reservation jail. periodt 💅

these are the sister functions in the same little execbuf-util friend group, go say hi 🧚

ngl this is kernel-side stuff, so be careful out there — no guessing at behaviour beyond what's written, okay? she's precise and so are you 🎀

so yeah, that's the whole page bestie 🌸 we ate, we left no crumbs, and honestly? she's a little minimal but she gets the job done. mwah 💋
