Enum SpectreV2Mitigation 

Source 
pub enum SpectreV2Mitigation {
    Ibrs,
    IbpbRetpoline,
    IbpbRetpolineStibp,
}
Expand description

An architecturally prescribed mitigation for Spectre v2.

Variants§

§

Ibrs

Enhanced/always-on IBRS (i.e., IBRS that can be enabled once without automatic disabling) is preferred alone.

§

IbpbRetpoline

IBPB and/or retpoline are recommended.

§

IbpbRetpolineStibp

IBPB and/or retpoline are recommended - and STIPB, though not preferred as a performant mitigation, is also present and may be used.
