STRUCT DRM_TEGRA_GET_SYNCPT(9)

✨ struct drm_tegra_get_syncpt(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this little cutie lives in the kernel docs and it's literally just the parameter struct for the get syncpoint IOCTL. no cap, that's the whole vibe.

🎀 NAME 🎀

struct drm_tegra_get_syncpt — the parameters for the get syncpoint IOCTL 🦋

🌸 SYNOPSIS 🌸

struct drm_tegra_get_syncpt {
    __u64 context;
    __u32 index;
    __u32 id;
 };

💖 Members 💖

she has three fields and honestly? each one is doing main character energy in its own way:

• context — the application context, iykyk 🌈 this is the thing that identifies the channel you're asking for the syncpoint ID from.
• index — the index of the client syncpoint you want the ID of 👑
• id — the actual ID of the given syncpoint ⭐ and here's the tea: the kernel sets this one for you, but only upon successful completion of the IOCTL. so like, don't go reading it before that, bestie, that's not it 🙈
