Linux 5.12-rc5 Released - It's Bigger Than Average

Today's release of Linux 5.12-rc5 is "bigger than average" for this stage of kernel development and if that keeps up is likely to result in an extra week's worth of testing / an -rc8 release ahead of Linux 5.12 final, but it's too early to call at this stage.

Initial Support For The Rust Language Lands In Linux-Next

For a long while now Linux kernel developers have discusses the prospects of optionally allowing the Rust language to be used for new device drivers within the Linux kernel areas and other areas within the kernel for this language that prides itself on safety and performance. As the first baby step towards that dream, initial Rust support appeared this week in the Linux-Next tree.

Linux 5.12-rc2 Released Early - A Rare Friday Kernel Due To That Nasty Corruption Issue

While Linus Torvalds long has released his new kernel releases -- both release candidates and the inaugural stable releases -- every Sunday, there are the occasional exceptions like this week with Linux 5.12-rc2 being issued on Friday night. The Linux 5.12-rc2 release has come early due to that nasty file-system corruption issue stemming from botched swapfile handling.

That Linux 5.12 Severe Data Corruption Bug Hits Intel CI Systems - Issue Caused By Swap File

Last week I issued a warning of possible data loss on the early Linux 5.12 kernel code that was reliably leaving my test systems severely corrupted. Intel's internal graphics test systems it turns out have now been bitten by this issue in encountering this significant file-system corruption and as such they've been quick to jump on the issue - there's now an idea what's causing the nasty issue and a workaround by reverting select patches.

More Open-Source Adreno 500 Series Support, A6xx Speedbin Sent In For Linux 5.12

Last week the main set of DRM subsystem updates were sent in for the Linux 5.12 merge window. That pull included exciting additions like Radeon RX 6000 series OverDrive and Intel Xe VRR. Mistakenly left out of that pull request last week were the open-source Qualcomm Adreno driver improvements for the "MSM" kernel driver while now that code has landed.

Linux 5.12 Git Seeing New Code Land Following Winter Storm

While the first week of a new merge window is often one of the busiest times for Linus Torvalds in overseeing the Linux kernel, until last night there was no actual Linux 5.12 code being pushed into the Linux Git repository. Linus was offline most of the week due to winter storms preventing him from pushing to the Git repository and interacting much with the mailing list.

Linux 5.12 Adds Instruction Latency Reporting To Perf

An exciting new capability with perf in Linux 5.12 is the ability to collect instruction latency metrics as part of the performance reports, but relies on hardware capabilities for now only found in next-generation Intel Xeon "Sapphire Rapids" processors.

VRR For Intel Xe Graphics, Radeon RX 6000 Series Overclocking With Linux 5.12

The DRM kernel graphics/display driver updates were sent in today for the ongoing Linux 5.12 merge window. Two of the biggest features are VRR/Adaptive-Sync now being supported for Intel Gen12/Xe Graphics while on the AMD side there is initial "OverDrive" overclocking support for their newest RDNA 2 GPUs.

Linux 5.10.17 Backports CPUFreq Patches From 5.11 - Benchmarks

Released yesterday was the Linux 5.10.17 LTS kernel and what makes this point release a bit more notable than usual is that it backports the CPUFreq patches from 5.11 that were used for addressing the earlier AMD performance regression on Linux 5.11 and often leading to net improvements as well over prior kernel series. The CPUFreq patches were back-ported while the AMD frequency invariance support was not, so what does the performance look like for the Linux 5.10 LTS kernel? Here are some benchmarks.
