HUC MEMORY MANAGEMENT(9)

🦋 HuC Memory Management 🦋

okay bestie, welcome to the Kernel API Manual — section 9, the HuC memory-management corner of the universe, and yes we're getting into it ✨

Just like the GuC, the HuC literally can't do any memory allocations on its own 😭 the difference? The allocations for HuC usage are handled by the userspace driver instead of the kernel one — slay for userspace, I guess 💅

The HuC accesses the memory via the PPGTT belonging to the context loaded on the VCS executing the HuC-specific commands. That's the whole vibe: PPGTT + context + VCS + HuC-specific commands, no cap 🫶
