STRUCT DAL_ALLOCATION(9)

🎀 NAME 🎀

okay bestie, this is struct dal_allocation from the Kernel API Manual, and its whole gig is literally: Tracks mapped FB memory for SMU communication. That’s the vibe — it keeps tabs on mapped FB memory for SMU communication. No cap. 💅

✨ SYNOPSIS ✨

here’s the exact shape, bestie — do not come for the indentation, it’s iconic:

       struct dal_allocation {
           struct list_head list;
           struct amdgpu_bo *bo;
           void *cpu_ptr;
           u64 gpu_addr;
        };

💖 Members 💖

okay so every field is doing main character work:

• list — list of dal allocations. literally the list of dal allocations. 🫶
• bo — GPU buffer object. the GPU buffer object, periodt. 🔥
• cpu_ptr — CPU virtual address of the GPU buffer object. yes bestie, CPU virtual address of the GPU buffer object. ✨
• gpu_addr — GPU virtual address of the GPU buffer object. GPU virtual address of the GPU buffer object, exactly. 🌸
