Ampere Altra vs. Amazon Graviton2 Linux Performance Benchmarks
Last month we provided benchmarks of Ampere Altra against Intel Xeon and AMD EPYC with the Q80-33 CPUs in a 2P / 160 core configuration. From that article, reader questions were raised about how this high performance ARM server chip compares to Amazon's Graviton2 processors, so in this article today are such benchmarks. The Graviton2 via an AWS m6g.metal instance with 64 cores was compared to the Ampere Altra Q80-33 in its 2P 160 core configuration, 1P 80 core configuration, and then a 64 core configuration to match the Graviton2 by disabling the excess cores.

L1d Cache Flushing On Context Switch Trying Again But More Conservative In 2021
Coming out in early 2020 were patches by an Amazon engineer to implement flushing the L1 data cache on context switching in the name of security given the various data sampling vulnerabilities. That work so far has been rejected from the mainline kernel but today was updated and makes it harder to enable and thus moving forward could stand chances to finally see the opt-in functionality merged to mainline...

Well, here are those numbers for those wanting to pursue aggressive compiler optimizations on a shiny AMD Ryzen 9 5950X.
Intel Haswell GT1 Graphics Have Been Busted The Past Half-Year On Linux
While Intel is generally well regarded for their Linux development practices especially as it pertains to continuous integration and their test labs for vetting code prior to reaching the mainline Linux kernel to minimize the risk of regressions or other unintended side effects, those running older Haswell GT1 low-end graphics have seen the past several kernel versions going back a half-year yield a GPU hang at boot...

A Look At The CPU Security Mitigation Costs Three Years After Spectre/Meltdown
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.

Benchmarking OpenMandriva Lx 4.2 With Its AMD Zen Optimized Build
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.

Zink With Mesa 21.0 Now Exposes OpenGL 4.1
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...

Radeon Linux Drivers Now Only Officially Support Smart Access Memory On Zen 3 + RDNA2
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...

AMD Performance On Linux 5.11 Remains Mixed Due To Schedutil With Frequency Invariance
Back on Christmas I wrote about Linux 5.11 regressing for AMD performance on Zen 2 and newer systems where the just-added CPU frequency invariance support was often hurting various workloads when using the default "Schedutil" scheduler utilization frequency scaling governor. Since then and through the holidays I have been carrying out many more benchmarks looking at the Linux 5.11 performance with a particular focus on the AMD desktop/server platforms.

There's nothing quite like some fun holiday-weekend reading as a fiery mailing list post by Linus Torvalds. The Linux creator is out with one of his classical messages, which this time is arguing over the importance of ECC memory and his opinion on how Intel's "bad policies" and market segmentation have made ECC memory less widespread...
dav1d 0.8 Released With More Optimizations - More AMD Performance
Dav1d 0.8 was released this weekend (and subsequently 0.8.1 too) as the latest major release for this CPU-based AV1 decoder hosted by the VideoLAN project.
