    Why is it so hard to provide an option to disable PSP? Poor technical design, or they do it on purpose to leave backdoors for someone (Big Brother)?
    PSP is necessary for booting the system, if I remember right. They could probably neuter it heavily, but if my memory is correct, they can't fully disable it.

      Which means none of these qualifies as a security issue, as if you have such access to a system, you can do whatever the hell you want anyway.

        Seems most issues were connected with these ASMedia USB/SATA controllers, which exists for about 6 years as they say with poor record of fixing anything... hm, so what could AMD even can do about that? Maybe only to use something else on Zen+ or what

          It's probably too late for Zen+, if the issue is even real. It'd probably be possible to get a fix in for Zen2.

The info that was available suggested that disabling this simply disable the MOBO interface to the PSP, but that the PSP itself was likely still active and capable of... who knows what; it's all an AMD secret.
            I can provide a screenshot showing the option is there and I have "disabled it". As far as whether it really disables it... who knows outside of AMD.


            Also this report... more signs it is a stock short selling attempt

                Whatever, i meant you can't fix current. This is funny to me as most of these "AMD flaws" were connected with ARM PSP and ASMedia controllers...

                All issues they mentioned are somewhat about ASMedia chipsets and ARM based PSP

                Thus, they should name this "Ryzen platform flaws under admin rights only" as they only talk about these, not "AMD flaws"

                  I'm not saying Intel, but it's Intel.

                    Meltdown must have really hurt.

                      This plus the fact that everyone in the video is greenscreened against stock images. They clearly either don't have an office or then they don't want people to figure out where they're actually based.

                      I somehow get the feeling that we're either looking at a bunch of hacking team type morons or then an Intel FUD campaign, which considering their past actions I wouldn't put past them.
