xe_guc_buf_sync_read(9)

🎀 NAME 🎀

okay so bestie, welcome to the Kernel API Manual 💖 — this one's about xe_guc_buf_sync_read, and what it does is literally copy the data from the GPU memory over to the sub-allocation. that's it, that's the whole vibe ✨

---

🌸 SYNOPSIS 🌸

here's the exact shape of it, no cap:

void * xe_guc_buf_sync_read (const struct xe_guc_buf buf );

---

💅 ARGUMENTS 💅

• buf — the xe_guc_buf you wanna sync 🫶 that's the one, that's the whole argument, we love a single-arg icon

---

⭐ RETURN ⭐

it hands you back a CPU pointer of the sub-allocation 👑 so like, a pointer you can actually use from the CPU side. slay.

mwah 💋 that's the whole page! this lil guy comes from the source tree at ./drivers/gpu/drm/xe, dated October 2026, and it's filed under xe_guc_buf_sync_read(9) ✨💜 go forth and sync those buffers, bestie 🧚‍♀️
