PXP is an i915 componment, that helps user space to establish the hardware protected session and manage the status of each alive software session, as well as the life cycle of each session. This ioctl is to allow user space driver to create, set, and destroy each session. It also provides the communication chanel to TEE (Trusted Execution Environment) for the protected hardware session creation.
