We've known that Intel's P-State Linux CPU frequency scaling driver in general can be a bit quirky and especially so when dealing with Intel integrated graphics where the iGPU and CPU share the same power envelope. This has been shown with examples like using the "powersave" governor to boost iGPU performance while discrete graphics owners are generally best off switching over to the "performance" governor. As the latest though on helping the iGPU front with P-State, there is a new patch series talking up big gains in performance and power efficiency...

Load Value Injection (LVI) is being disclosed today as a new class of transient-execution attacks and the researchers claim can defeat all existing mitigations around Meltdown, Foreshadow, Zombieload, RIDL and Fallout. The researchers say LVI can affect virtually any access to memory and compiler-based mitigations can be expensive...

With the Linux 5.7 kernel this spring there is going to be a new exFAT file-system drive developed by Samsung as outlined last week. While that is being added to the formal file-system area of the kernel rather than staging so both could co-exist for a transition period, already with Linux 5.7 will be the removal of the existing staging driver...

After running behind schedule from the planned release last month and an extra release candidate being warranted, LLVM 10.0 should be releasing this coming weeks along with its sub-projects -- most notably, the Clang 10.0 C/C++ compiler. Here is a look at the big ticket items of LLVM/Clang 10.0...

Not many AMD Radeon Linux gamers have been using the "sisched" SI machine instruction scheduler in recent times. This non-default scheduler hasn't been well maintained. Additionally, when on the RADV Vulkan driver, using the Valve-backed compiler back-end has been far superior. As such, SISCHED has now been gutted out of Mesa...

While the cross-distribution AppStream specification standardizes the software component metadata for use by Linux software centers/stores, it turns out many open-source developers aren't interested in or time limited by learning the spec and maintaining the metadata. As such, Matthias Klumpp has now developed the MetaInfo Creator for easily creating this important cross-distro metadata for packages...

Not only have GNOME developers been fixing many bugs this week ahead of the 3.36 stable desktop release next week, but coincidentally KDE developers were also going heavy on the bug fixes this week...

Linux 5.4 brought a preliminary Microsoft exFAT file-system driver after Microsoft made the exFAT specification public and encouraged the support for Linux. But with the Linux 5.7 kernel this spring, a new exFAT file-system driver is going to land that is a much improved version of the earlier code...

Going back about two years has been work by Linaro on "thermal pressure" support for the scheduler so that it can make better task placement decisions among CPU cores when any of the core(s) are being restricted by running too hot. That work is now set to finally land this spring with the Linux 5.7 kernel...

Ubuntu 20.04 is coming out next month and will be the first LTS release with Ubuntu desktop ZFS support available for the root file-system after it was made easy-to-deploy the Ubuntu desktop on ZFS last cycle. One of the areas being expanded upon with the ZFS support has been Ubuntu's Zsys daemon for offering extra functionality for ZFS-based setups...
