TrustZone is a hardware architecture by ARM which main porpuse is to enable the construction of a programmable environment that allows the confidentiality and integrity of almost any asset to be protected from specific attacks.

The GPU driver is divided into two layers: | |||
*The first layer is running in kernel mode: represents the base driver for the whole stack. This layer provides the essential hardware access, device management, memory management, command queue management, context management and power management. | |||
*The second layer is running in user mode: implements the stack logic and provides the APIs (OpenGL ES, OpenCL, OpenVX, Vulkan) to the upper layer applications. | |||
