With this week marking three years since Spectre and Meltdown were made public in ushering in a wave of CPU security disclosures that followed and mitigations that often resulted in measurable performance hits, here is a look at how the performance costs stand today with various new and older Intel CPUs as well as AMD processors too. This article is looking at the current performance costs under Linux with the default mitigations and then the run-time disabling of the relevant mitigations for each of the processors under test while using an up-to-date Ubuntu 20.10 paired with the new Linux 5.10 LTS kernel.

Yet another big change being eyed for Fedora 34 is to sign individual files within shipped RPM packages. The signatures will use the Linux Integrity Measurement Architecture (IMA) and in turn can be used to enforce run-time policies around only allowing the execution of trusted files...

While Intel has Clear Linux as an aggressively optimized Linux distribution catering towards their hardware, there isn't a direct equivalent for optimally showcasing the performance potential of current AMD platforms. Clear Linux often offers leading performance on Zen CPUs but that is obviously not by design but just an artifact of a lot in common between the latest Intel and AMD microarchitecture features. One of the few distributions (or only notable one) offering specific AMD Zen optimized builds has been OpenMandriva. With the OpenMandriva Lx 4.2 release candidate shipping this week, I ran some fresh benchmarks looking at how OpenMandriva Lx 4.2 RC1 compares between its generic x86_64 image and that of the Zen optimized build as well as in turn how that performance compares to Clear Linux and Ubuntu 20.10.

While for months there have been experimental patches taking Zink to OpenGL 4.6 for this OpenGL-on-Vulkan translation layer integrated into Mesa, the upstreaming process around testing and code review is quite lengthy with up until today still only exposing OpenGL 3.3 with mainline Mesa. But with the latest Git commits, Zink is now up to OpenGL 4.1...

While many Linux users were excited when finding out the open-source AMD Radeon Linux drivers were allowing Smart Access Memory (Resizable BAR) support on older motherboards/CPUs and older Radeon GPUs rather than basically the very latest AMD products as seen on Windows, there is a change of course due to bugs. Now, officially, Mesa 21.0 is just enabling Smart Access Memory for systems with AMD Zen 3 processors and RDNA 2 graphics cards though if you have other hardware you can force-enable it...
