🌸 __i915_gem_object_get_sg(9) 🌸

Okay bestie, welcome to the __i915_gem_object_get_sg(9) page from the Kernel API Manual. This is the helper that finds the target scatterlist pointer and the target page position using the pgoff_t n input argument and drm_i915_gem_object; it uses an internal shmem scatterlist lookup function. 🫶

🎀 NAME 🎀

Let's get the vibe check out of the way: __i915_gem_object_get_sg is the helper that finds the target scatterlist pointer and the target page position using the pgoff_t n input argument and drm_i915_gem_object. It uses an internal shmem scatterlist lookup function. ✨

🎀 SYNOPSIS 🎀

struct scatterlist * __i915_gem_object_get_sg (struct
drm_i915_gem_object *obj , pgoff_t n , unsigned int *offset );

✨ ARGUMENTS ✨

  • obj — the i915 GEM buffer object. 👑
  • n — page offset. 🌸
  • offset — the searched physical offset; it gets used for returning the physical page offset value. 💖

💅 DESCRIPTION 💅

Okay so it uses drm_i915_gem_object's internal shmem scatterlist lookup function as i915_gem_object_page_iter, and then it calls __i915_gem_object_page_iter_get_sg. No cap. 🦋

Bestie, it is recommended to use the wrapper macro i915_gem_object_get_sg. Also see __i915_gem_object_page_iter_get_sg. 💅

🔥 RETURN 🔥

It hands back the target scatterlist pointer and the target page position. Periodt. 🔥
