STRUCT DRM_TEGRA_GEM_GET_TILING(9)

💅 struct drm_tegra_gem_get_tiling(9) 💅

okay so this is a page from the Kernel API Manual and it's literally the cheat sheet for struct drm_tegra_gem_get_tiling — the little parameter bundle you hand to the get-tiling IOCTL. yes bestie, get. we're asking the kernel questions here, not telling it what to do. 🎀

---

✨ NAME ✨

struct drm_tegra_gem_get_tiling — the parameters for the get tiling IOCTL, periodt 💅

---

🦋 SYNOPSIS 🦋

struct drm_tegra_gem_get_tiling {
    __u32 handle;
    __u32 mode;
    __u32 value;
    __u32 pad;
 };

(no cap, that's the whole struct — she's compact and she knows it ✨)

🌸 Members 🌸

okay let's meet the cast, one field at a time 🫶

• handle — handle to the GEM object you're asking about, i.e. the one whose tiling parameters you wanna query. it's giving "who's this about?" energy 👑
• mode — the tiling mode currently associated with the GEM object. lowkey important: the kernel sets this one for you, upon successful completion of the IOCTL. you don't fill it in, you receive it 🎁
• value — the tiling mode parameter currently associated with the GEM object. again, set by the kernel upon successful completion of the IOCTL. so you read it, you don't write it, iykyk 😌
• pad — structure padding that may be used in the future. must be 0. fr fr, zero it out, don't get cute with it 🙈

💀 real talk: mode and value are the kernel's little gifts to you after a successful IOCTL, so don't rock up with your own values expecting them to mean anything. they're outputs. and pad stays 0. that's the vibe check and you passed 🧚
