Available on AArch64 only.
Expand description

EL: Defines the privilege level of executing code. Higher values have more privileges.

Variants§

§

Zero = 0

EL0, used for unprivileged user code.

§

One = 1

EL1, used for OS kernel code.

§

Two = 2

EL2, used for hypervisors in virtualized systems.

§

Three = 3

EL3, used for the secure manager.

Implementations§

Source§
