  • EFF vs IoT DRM, OMG!

    What with the $400 juicers and the NSFW smart fridges, the Internet of Things has arrived at that point in the hype cycle midway between "bottom line" and "punchline." Hype and jokes aside, the reality is that fully featured computers capable of running any program are getting cheaper and more powerful and smaller with no end in sight, and the gadgets in our lives are transforming from dumb hunks of electronics to computers in fancy cases that are variously labeled "car" or "pacemaker" or "Alexa."

    We don't know which designs and products will be successful in the market, but we're dead certain that banning people from talking about flaws in existing designs and trying to fix those flaws will make all the Internet of Things' problems worse.

The Spectre/Meltdown Performance Impact On Linux 4.20, Decimating Benchmarks With New STIBP Overhead

As outlined yesterday, significant slowdowns with the Linux 4.20 kernel turned out to be due to the addition of the kernel-side bits for STIBP (Single Thread Indirect Branch Predictors) for cross-HyperThread Spectre Variant Two mitigation. This has incurred significant performance penalties with the STIBP support in its current state with Linux 4.20 Git and is enabled by default at least for Intel systems with up-to-date microcode. Here are some follow-up benchmarks looking at the performance hit with the Linux 4.20 development kernel as well as the overall Spectre and Meltdown mitigation impact on this latest version of the Linux kernel. Some users have said AMD also needs STIBP, but at least with Linux 4.20 Git and the AMD systems I have tested with their up-to-date BIOS/microcode, that hasn't appeared to be the case. Most of the AMD STIBP references date back to January when Spectre/Meltdown first came to light. We'll see in the week ahead if there is any comment from AMD but at this time seems to be affecting up-to-date Intel systems with the Linux 4.20 kernel. Read more
