xe_guc_cache...ddr_from_ptr(9)

🎀 NAME 🎀

okay so this is from the Kernel API Manual, and the function is xe_guc_cache_gpu_addr_from_ptr — it does a lookup of a GPU address using the pointer, bestie. That's the whole vibe. ✨

🌸 SYNOPSIS 🌸

the signature is giving:

u64 xe_guc_cache_gpu_addr_from_ptr (struct xe_guc_buf_cache *cache ,
       const void *ptr , u32 size );

🦋 ARGUMENTS 🦋

• cache — the xe_guc_buf_cache with sub-allocations, iykyk.
• ptr — the CPU pointer of the sub-allocation, fr fr.
• size — the size of the data, periodt.

✨ RETURN ✨

It returns a GPU address on success, or 0 if the pointer was unrelated. no cap, that's the return situation 💖
