Some devices (including most Tegra-based consumer devices on the
|
|
|
|
|
market) are booted with the Trusted Foundations secure monitor
|
|
|
|
|
active, requiring some core operations to be performed by the secure
|
|
|
|
|
monitor instead of the kernel.
|
|
|
|
|
|
|
|
|
|
This option allows the kernel to invoke the secure monitor whenever
|
|
|
|
|
required on devices using Trusted Foundations. See
|
