STRUCT PANTHOR_KERNEL_BO(9)

💖 NAME 💖

struct panthor_kernel_bo — Kernel buffer object. Welcome to the Kernel API Manual, bestie; this is the struct panthor_kernel_bo(9) page and it's giving very "kernel-only main character" energy 🎀.

✨ SYNOPSIS ✨

       struct panthor_kernel_bo {
           struct drm_gem_object *obj;
           struct panthor_vm *vm;
           struct drm_mm_node va_node;
           void *kmap;
        };

🌸 Members 🌸

• obj — the GEM object backing this kernel buffer object. literally the backing track of this whole struct 🎶
• vm — the VM this private buffer is attached to. its home base, no cap 🫶
• va_node — the VA space allocated to this GEM. address-space allocation, slay 💅
• kmap — the kernel CPU mapping of gem. lowercase gem and all, we keep it exactly as written 🎀

🦋 Description 🦋

These objects are only manipulated by the kernel driver and are not directly exposed to the userspace. So they're lowkey private, iykyk 🙈.

That said, the GPU address of a kernel BO might be passed to userspace though. So the address can make a little cameo ✨.

Sign-off cuteness: from source/version ./drivers/gpu/drm/panthor, dated October 2026, this was struct panthor_kernel_bo(9) — mwah, go slay some kernel buffers 💅✨
