✨ xe_gt_ccs_mode_sysfs_init(9) ✨

okay so this one's from the Kernel API Manual, and it's genuinely such a mood — it's the function that spins up the CCS mode sysfs interfaces 💅

🌸 NAME 🌸

xe_gt_ccs_mode_sysfs_init — the glow-up moment where the CCS mode sysfs interfaces get initialized 🎀

---

🦋 SYNOPSIS 🦋

int xe_gt_ccs_mode_sysfs_init (struct xe_gt *gt );

---

🍓 ARGUMENTS 🍓

• gt — the GT structure, bestie. that's the whole vibe. that's the whole argument 🫶

---

👑 DESCRIPTION 👑

so through a per-gt ccs_mode sysfs interface, the user can enable a fixed number of compute hardware engines — and the available compute slices get allocated to those engines. iconic behavior, no cap ✨

this user configuration change triggers a gt reset, and it's expected that there are no open drm clients while you're doing it. like, fr fr, read that twice — you're resetting the GT, so don't be out here with clients hanging open 🙈

the number of available compute slices is exposed to the user through a per-gt

and that's literally where the sentence ends in the source, bestie 😭 it just stops. not me leaving it exactly as it is because every detail stays.

---

🔥 RETURN 🔥

returns an error value when it fails, and 0 on success. slay when it's 0 💖

and that's the page, bestie 🧚 this one came out of ./drivers/gpu/drm/xe, dated October 2026, and yeah — it's xe_gt_ccs_mode_sysfs_init(9) all the way down. periodt 💜
