Query: Safe and Practical GPU Acceleration in TrustZone   We present a holistic design for GPU-accelerated computation in TrustZone
TEE. Without pulling the complex GPU software stack into the TEE, we follow a
simple approach: record the CPU/GPU interactions ahead of time, and replay the
interactions in the TEE at run time. This paper addresses the approach's key
missing piece -- the recording environment, which needs both strong security
and access to diverse mobile GPUs. To this end, we present a novel architecture
called CODY, in which a mobile device (which possesses the GPU hardware) and a
trustworthy cloud service (which runs the GPU software) exercise the GPU
hardware/software in a collaborative, distributed fashion. To overcome numerous
network round trips and long delays, CODY contributes optimizations specific to
mobile GPUs: register access deferral, speculation, and metastate-only
synchronization. With these optimizations, recording a compute workload takes
only tens of seconds, which is up to 95% less than a naive approach; replay
incurs 25% lower delays compared to insecure, native execution.
