STRUCT DRM_I915_GEM_EXEC_FENCE(9)

🎀 NAME 🎀

okay bestie, welcome to the Kernel API Manual entry for struct drm_i915_gem_exec_fence(9) — it’s an input or output fence for the execbuf ioctl. That’s the whole main-character job. 💅

✨ SYNOPSIS ✨

struct drm_i915_gem_exec_fence {
    __u32 handle;
    __u32 flags;
  #define I915_EXEC_FENCE_WAIT            (1<<0);
  #define I915_EXEC_FENCE_SIGNAL          (1<<1);
  #define __I915_EXEC_FENCE_UNKNOWN_FLAGS (-(I915_EXEC_FENCE_SIGNAL <<
1));
 };

💖 Members 💖

• handle — User’s handle for a drm_syncobj to wait on or signal. 🫶
• flags — Supported flags are:
  • I915_EXEC_FENCE_WAIT — Wait for the input fence before request submission. ⏳
  • I915_EXEC_FENCE_SIGNAL — Return request completion fence as output. 📤

🌸 Description 🌸

The request will wait for input fence to signal before submission. Like, it is not going anywhere until that input fence gives the signal. ⏳

The returned output fence will be signaled after the completion of the request. So the output fence pops after the request is done — iconic. ✨
