The past few days I've begun exploring the performance implications of the new Microarchitectural Data Sampling "MDS" vulnerabilities now known more commonly as Zombieload. As I shared in some initial results, there is a real performance hit to these mitigations. In this article are more MDS/Zombieload mitigation benchmarks on multiple systems as well as comparing the overall performance impact of the Meltdown/Spectre/Foreshadow/Zombieload mitigations on various Intel CPUs and also AMD CPUs where relevant.

While upstream SSH has disabled password logins for the root user as their default configuration the past number of years and that has carried over into being the out-of-the-box behavior for many operating systems, Fedora continues allowing password-based SSH root log-ins by default. But with the next Fedora release they are thinking about changing that default behavior...

Veteran Linux multimedia developer Paul Kocialkowski summed up the current situation this week of many hardware platforms having a general purpose micro-controller running a non-free firmware blob for coordinating the video decoding work. It makes it easier to program with this firmware-based approach but makes the driver less free and now with recent Linux infrastructure improvements could better support dealing with the video hardware itself...

Following last week's big feature update to the DRM graphics drivers, an initial batch of "fixes" has now been merged to the early Linux 5.2 development code for these Direct Rendering Manager drivers...

The default Linux mitigations for the new Microarchitectural Data Sampling (MDS) vulnerabilities (also known as "Zombieload") do incur measurable performance cost out-of-the-box in various workloads. That's even with the default behavior where SMT / Hyper Threading remains on while it becomes increasingly apparent if wanting to fully protect your system HT must be off...

Of Intel's many open-source projects, taking a central role at this year's Intel Open-Source Technology Summit was Clear Linux. Most Intel open-source efforts mentioned during the event point back to Clear Linux in some capacity and at OSTS2019 we finally heard some of the companies that are beginning to make use of Clear Linux...

A few days back I posted a number of Intel OpenCL benchmarks between their former Beignet and new "NEO" Linux compute stacks that was done using a Skylake NUC for the Iris Pro 580 graphics.
