amdgpu_gfx_...ring_end_use(9)

💅 amdgpu_gfx_enforce_isolation_ring_end_use — the Kernel API Manual page (section 9, bestie)

okay so this is the manual page for amdgpu_gfx_enforce_isolation_ring_end_use(9) from the Kernel API Manual — yes the whole name is a mouthful, we're saying it together, breathe 🫶

---

✨ NAME ✨

amdgpu_gfx_enforce_isolation_ring_end_use — the "okay we're done with the ring now" helper for rings that have enforced isolation turned on 💅

---

🌸 SYNOPSIS 🌸

void amdgpu_gfx_enforce_isolation_ring_end_use(struct amdgpu_ring *ring);

that's it. that's the whole signature. no return value, it's giving void main character energy ✨

---

🎀 ARGUMENTS 🎀

• ring — a pointer to the amdgpu_ring structure. literally just a pointer to the ring struct, she's not complicated 💖

---

🦋 DESCRIPTION 🦋

so this is the end_use helper implementation for gfx — the end half of the whole begin/end situation. what it does is serialize access to the gfx IP between kernel submission IOCTLs and KFD user queues whenever isolation enforcement is enabled 🔥

and like, because both of those things want the gfx IP, they each get a time slice when both are active. sharing is caring, no cap 🤝

bestie this one's from ./drivers/gpu/drm/amd/amdgpu, stamped October 2026, living in the Kernel API Manual section 9 — go read the begin_use one too, they're a matching set 🎀💖✨
