While most Linux gamers don't appear to be into GPU overclocking, one of the limitations of the Radeon RX 5000 "Navi" series support with the AMD open-source driver to date has been no overclocking support. With the upcoming Linux 5.5 kernel that is set to change...

OnLogic (formerly known as Logic Supply until a recent rebranding) announced the Karbon 700 back in August as a durable Linux-friendly computer largely intended for industrial applications but nothing prevents the user from using it as a passively, well-built desktop PC either. OnLogic recently sent over the Karbon 700 and it's been working out very well even with passively cooling an Intel Xeon eight-core / sixteen-thread processor, 16GB of RAM, 512GB NVMe storage, and more.

While this week we have posted a number of benchmarks on the JCC Erratum and its CPU microcode workaround that introduces new possible performance hits, also being announced this week as part of Intel's security disclosures was "Zombieload Variant Two" as the TSX Async Abort vulnerability that received same-day Linux kernel mitigations. I've been benchmarking the TAA mitigations to the Linux kernel since the moment they hit the public Git tree and here are those initial benchmark results on an Intel Cascade Lake server.

With yesterday's overview and benchmarks of Intel's Jump Conditional Code Erratum one of the areas where the performance impact of the updated CPU microcode exceeding Intel's 0~4% guidance was on the web browser performance. Now with more time having passed, here are more web browser benchmarks on both Chrome and Firefox while comparing the new CPU microcode release for the JCC Erratum compared to the previous release. Simply moving to this new CPU microcode does represent a significant hit to the web browser performance.

Now that Intel lifted its embargo on the "Jump Conditional Code" erratum affecting Skylake through Cascade Lake processors, while Intel's own Clear Linux was first to carry these patches they have now been sent out on the Binutils mailing list for trying to get the JCC optimization patches into the upstream Binutils/GAS code-base...

Merged to the mainline Linux kernel last week was a driver providing VirtualBox guest shared folder support with the driver up to now being out-of-tree but important for sharing files between the host and guest VM(s). While the driver was part of Linux 5.4-rc7, Linus Torvalds decided to delete this driver on Tuesday...

This morning I provided a lengthy look at the performance impact of Intel's JCC Erratum around the CPU microcode update issued for Skylake through Cascade Lake for mitigating potentially unpredictable behavior when jump instructions cross cache lines. Of the many benchmarks shared this morning in that overview, there wasn't time for any gaming tests prior to publishing. Now with more time passed, here is an initial look at how the Linux gaming performance is impacted by the newly-released Intel CPU microcode for this Jump Conditional Code issue.

Of the 77 security advisories Intel is making public and the three big ones of the performance-sensitive JCC Erratum, the new ZombieLoad TAA (TSX Asynchronous Abort), and iTLB Multihit No eXcuses, there are also two fixes to their kernel graphics driver around security issues separate from the CPU woes...

The Linux kernel has just received its mitigation work for the newly-announced TSX Asynchronous Abort (TAA) variant of ZombieLoad plus revealing mitigations for another Intel CPU issue... So today in addition to the JCC Erratum and ZombieLoad TAA the latest is iITLB Multihit (NX) - No eXcuses...

In addition to the JCC erratum being made public today and that performance-shifting Intel microcode update affecting Skylake through Cascade Lake, researchers also announced a new ZombieLoad side-channel attack variant dubbed "TSX Asynchronous Abort" or TAA for short...

Intel is today making public the Jump Conditional Code (JCC) erratum. This is a bug involving the CPU's Decoded ICache where on Skylake and derived CPUs where unpredictable behavior could happen when jump instructions cross cache lines. Unfortunately addressing this error in software comes with a performance penalty but ultimately Intel engineers are working to offset that through a toolchain update. Here are the exclusive benchmarks out today of the JCC erratum performance impact as well as when trying to recover that performance through the updated GNU Assembler.

With the Linux 5.4 kernel set to be released in the next week or two, here is a look at the performance going back to the days of Linux 4.16 from early 2018. At least the Linux kernel continues picking up many new features as due to security mitigations and other factors the kernel performance continues trending lower.

SUSE and other companies like DigitalOcean have been working on Linux core scheduling to make virtualization safer particularly in light of security vulnerabilities like L1TF and MDS. The core scheduling work is about ensuring different VMs don't share a HT sibling but rather only the same VM / trusted applications run on siblings of a core...
