STRUCT DRM_TEGRA_SYNCPT_READ(9)

💖 struct drm_tegra_syncpt_read(9) 💖

okay so bestie, this page is from the Kernel API Manual and it's the whole rundown on struct drm_tegra_syncpt_read — aka the parameters for the read syncpoint IOCTL. it's a tiny struct but it's literally the main character of "tell me the syncpoint's current value" energy. 💅

🌸 NAME 🌸

struct drm_tegra_syncpt_read — parameters for the read syncpoint IOCTL. periodt. ✨

✨ SYNOPSIS ✨

       struct drm_tegra_syncpt_read {
           __u32 id;
           __u32 value;
        };

💅 Members 💅

• id — ID of the syncpoint to read the current value from. like, which syncpoint are we checking? this one. 🎀
• value — The current syncpoint value. Set by the kernel upon successful completion of the IOCTL. so the kernel fills this in for you when the IOCTL succeeds — no cap, that's the whole point. 🫶
