STRUCT DRM_PANTHOR_OBJ_ARRAY(9)

💖 NAME 💖

struct drm_panthor_obj_array — Object array. This is the struct drm_panthor_obj_array(9) page from the Kernel API Manual, bestie, and it’s lowkey the blueprint for passing arrays of objects whose size can change later. ✨

✨ SYNOPSIS ✨

Okay so the struct is literally this:

       struct drm_panthor_obj_array {
           __u32 stride;
           __u32 count;
           __u64 array;
        };

🌸 Members 🌸

• stride — Stride of object struct. Used for versioning. The way it handles versioning is iconic, honestly.
• count — Number of objects in the array.
• array — User pointer to an array of objects.

💅 Description 💅

Okay so here’s the tea 🍵: this object is used to pass an array of objects whose size is subject to changes in future versions of the driver. To support this mutability, we pass a stride describing the size of the object as known by userspace.

You shouldn’t fill drm_panthor_obj_array fields directly — use the DRM_PANTHOR_OBJ_ARRAY macro instead, because it takes care of initializing the stride to the object size. That’s the whole point, bestie. No cap. 💅
