    Phoronix: Intel Gen7 Graphics Mitigation Will Try To Avoid Performance Loss In Final Version

    Intel's open-source developers working on their security mitigation for the Gen7 graphics hardware have volleyed a new version of the patch series for that mitigation currently causing big hits to Ivybridge / Haswell performance...

    How much you want to bet an executive read the performance reports yesterday!

    on another note could you imagine being a driver / kernel developer at Intel right now? You would be waking up every morning wondering what is next.

        Ouch. That sounds like there is much more to come. That ex-CEO of theirs must be smiling big on how he got away with full pockets before the problems went public.

          Why don't they also add a way to disable the mitigations?

            He performance impact won't be measurable. Not just noticeable, but even unmeasurable. That means benchmarks won't show different results. I wonder how true that will be.

              With the latest patch series it seems like things have improved.

                On Windows Intel did not implement this mitigation fully probably in fear of backlash due to the performance impact:
                Platforms based on Ivy Bridge, Bay Trail and Haswell do not have full mitigations at this time for the Windows OS. Updating the drivers for these platforms per the recommendation below will substantively reduce the potential attack surface. Intel is working on full mitigations for these platforms and will make them available once they are validated.

                  What about Gen 8 (Broadwell). They are closer to Gen 9 than 7, so do they also suffer a performance hit?

                    looks like they didn't get any internal volunteers for the job of Fireman!

                    So the job is to shovel BS!

                    Yep shovel and grease will rule the day.


                    This right here says it all: "the ability to work well in a matrixed organization is a must." I suspect that Intel hasn't yet learned that their "matrixed organization" is what lead to the current problems. I see this idiocy as doing the same old thing in the hopes that just doing it better and more will correct the problem created.
