amdgpu_vm_sdma_commit(9)

💖 amdgpu_vm_sdma_commit — commit SDMA command submission 💖

okay so bestie, welcome to amdgpu_vm_sdma_commit(9) from the Kernel API Manual — yes, that's the whole header, it's giving kernel-doc energy and we're obsessed. this one is short and sweet: it's the lil function that actually commits an SDMA command submission. the finale. the send button. periodt. 🔥

---

✨ SYNOPSIS ✨

int amdgpu_vm_sdma_commit (struct amdgpu_vm_update_params *p , struct
dma_fence **fence );

that's it, that's the whole signature. two args, one int coming back at you. slay. 💅

---

🎀 ARGUMENTS 🎀

• p — this one's a pointer to the amdgpu_vm_update_params struct — and no, the manpage will not explain it here, it just says "see amdgpu_vm_update_params definition." like okay gatekeep a little 😭 go look up the struct bestie, it's defined elsewhere, iykyk.
• fence — a struct dma_fence **, and it's where the resulting fence lands. so like, the receipt for the submission. keep it safe 🫶

---

👑 RETURN 👑

it returns an int, and here's the vibe: Negativ errno (that's the doc's own spelling, we're keeping it fr fr, iconic typo 💀) when something goes wrong — and 0 for success. zero is the good number. zero means we ate and left no crumbs. ⭐

no cap, if you get anything other than 0 back, that's a negative errno and something went sideways. handle it. 🙈
