CONFIG_ARMV8_R¶

(No prompt – not directly user assignable.)

Type: bool

Help¶

This option signifies the use of an ARMv8-R processor
implementation.

From https://developer.arm.com/products/architecture/cpu-architecture/r-profile:
The Armv8-R architecture targets at the Real-time profile. It introduces
virtualization at the highest security level while retaining the
Protected Memory System Architecture (PMSA) based on a Memory Protection
Unit (MPU). It supports the A32 and T32 instruction sets.

Direct dependencies¶

CPU_AARCH64_CORTEX_R && ARM64

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
