CONFIG_SPECULATIVE_EXECUTION: Speculative subroutine return

General informations

The Linux kernel configuration item CONFIG_SPECULATIVE_EXECUTION has multiple definitions:

Speculative subroutine return found in arch/sh/Kconfig.cpu

The configuration item CONFIG_SPECULATIVE_EXECUTION:

• prompt: Speculative subroutine return
• type: bool
• depends on: CONFIG_CPU_SUBTYPE_SH7780 || CONFIG_CPU_SUBTYPE_SH7785 || CONFIG_CPU_SUBTYPE_SH7786
• defined in arch/sh/Kconfig.cpu
• found in Linux kernels: 2.6.25–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.11, 6.12-rc+HEAD

Help text

This enables support for a speculative instruction fetch for subroutine return. There are various pitfalls associated with this, as outlined in the SH7780 hardware manual.

If unsure, say N.
