STRUCT DRM_I915_GEM_EXECBUFFER_EXT_TIMELINE_FENCES(9)

🌸 NAME 🌸

Welcome to STRUCT DRM_I915_GEM_EXECBUFFER_EXT_TIMELINE_FENCES(9), bestie — this page lives in the Kernel API Manual 💖

struct drm_i915_gem_execbuffer_ext_timeline_fences — Timeline fences for execbuf ioctl. ✨

---

✨ SYNOPSIS ✨

Here’s the struct, character-for-character, no remix:

       struct drm_i915_gem_execbuffer_ext_timeline_fences {
         #define DRM_I915_GEM_EXECBUFFER_EXT_TIMELINE_FENCES 0;
           struct i915_user_extension base;
           __u64 fence_count;
           __u64 handles_ptr;
           __u64 values_ptr;
        };

---

🧚 Members 🧚

• base — Extension link. See struct i915_user_extension. 🫶
• fence_count — Number of elements in the handles_ptr & value_ptr arrays. 🔢
• handles_ptr — Pointer to an array of struct drm_i915_gem_exec_fence of length fence_count. 👉
• values_ptr — Pointer to an array of u64 values of length fence_count. Values must be 0 for a binary drm_syncobj. A Value of 0 for a timeline drm_syncobj is invalid as it turns a drm_syncobj into a binary one. 🚨

---

🌈 Description 🌈

This structure describes an array of drm_syncobj and associated points for timeline variants of drm_syncobj. 🦋

🚨 Real talk: it is invalid to append this structure to the execbuf if I915_EXEC_FENCE_ARRAY is set. Not “spicy”, not “edgy” — invalid. 💀
