💅 drm_gem_dma_object_mmap(9) — a Kernel API Manual moment ✨

okay bestie, welcome to the group chat for drm_gem_dma_object_mmap(9). This is the Kernel API Manual page, and she's here to explain the GEM object mmap helper with main-character energy. no cap 🫶

🎀 NAME 🎀

drm_gem_dma_object_mmap — the GEM object function for drm_gem_dma_mmap().

✨ SYNOPSIS ✨

here's the signature, literally exactly:

       int drm_gem_dma_object_mmap (struct drm_gem_object *obj , struct
       vm_area_struct *vma );

🌸 ARGUMENTS 🌸

• obj — the GEM object.
• vma — the VMA for the area to be mapped.

🦋 DESCRIPTION 🦋

This function wraps drm_gem_dma_mmap. Drivers that employ the dma helpers should use it as their drm_gem_object_funcs.mmap handler. it's giving "tiny wrapper, big main-character energy," and if that's your driver's setup, slay, this is the handler 💖

💫 RETURN 💫

0 on success, or a negative error code on failure. periodt 💅
