| H A D | cpu-features.rst | 1 Arm CPU Features
4 CPU features are optional features that a CPU of supporting type may
5 choose to implement or not. In QEMU, optional CPU features have
10 Cortex-A15 and the Cortex-A57, which respectively implement Arm
11 architecture reference manuals ARMv7-A and ARMv8-A, may both optionally
12 implement PMUs. For example, if a user wants to use a Cortex-A15 without
13 a PMU, then the ``-cpu`` parameter should contain ``pmu=off`` on the QEMU
14 command line, i.e. ``-cpu cortex-a15,pmu=off``.
16 As not all CPU types support all optional CPU features, then whether or
18 that implement the ARMv8-A architecture reference manual may optionally
