"While AMD is not currently aware of any code that would be
considered vulnerable due to PSF behavior, this whitepaper examines the potential security implications of PSF, in
general, as well as mechanisms that are designed to disable the feature if desired. AMD believes that for most
applications, the security risk of PSF is likely low and where isolation is required, techniques such as address space
isolation are preferred over software sandboxing."
"AMD recommends leaving the Predictive Store Forwarding feature enabled as the default setting."
