Last week I wrote about a change for the Linux kernel would better protect entropy sent in from user-space as a change driven as a result of some Linux distributions (such as Fedora) using a CPU jitter random number generator to resolve the lack of entropy at boot time and that on systemd-enabled Linux systems sometimes leading to slow boot times. That change has now ended up being queued into Linux 4.18 rather than having to wait for 4.19...

Last year Microsoft announced the "GVFS" open-source project as the Git Virtual File-System. Many took issue with Microsoft's open-source project being called GVFS since for years prior GNOME has been developing the well known GVfs as the virtual file-system for GIO/GLib. At first Microsoft resisted calls for changing their project's name, but now are making good on doing so...

Intel's open-source PowerTOP utility has been around for more than a decade now for aiming to extend the battery life of x86 Linux laptops. Following the recent Linux laptop battery life benchmarks of various distributions, a Phoronix Premium patron was asking whether PowerTOP still makes a difference with 2018 Linux distributions... Here are some fresh test results.

Following the GCC 9.0 benchmarks earlier this week I ran some tests seeing how the GCC 8 stable compiler and GCC 9 development state compare to the LLVM Clang 6.0.1 stable compiler and LLVM Clang 7.0 development. Here are those benchmarks using the AMD EPYC 7601 32-core / 64-thread processor.

Back during GDC 2018, Alen Ladavac serving as the CTO of Croteam presented on their research and testing into frame timing for helping uncover why some games are stuttering even when being rendered at high frame-rates. The short story is the issue can be addressed by just not measuring the time for rendering each frame in a game but to measure the time needed to actually present that frame on a display output. For that there is VK_GOOGLE_display_timing for Vulkan and other similar extensions...

Mesa 18.2 is going to be branched at the end of the month to mark the end of feature development for this quarterly Mesa feature release. This is a few weeks later than originally scheduled and has allowed for some extra features to land. Here is a look at some of the Mesa 18.2 changes on the way...

Since January there has been KPTI in the x86_64 Linux kernel as Kernel-based Page Table Isolation for mitigating the Meltdown CPU vulnerability. On the back-burner since then has been KPTI support for the Linux x86 32-bit kernel to protect those using older 32-bit-only processors. With the upcoming Linux 4.19 kernel, KPTI is landing for Linux x86 32-bit. Here are sone benchmarks showing the performance penalty when upgrading to this new kernel on an Ubuntu i686 laptop.

Back in 2012 was feature work to upgrade Fedora from using the Liberation Fonts to Liberation Fonts 2. That change at the time for Fedora 19 was then diverted due to the updated fonts causing some fuzzy/blurred rendering. That issue has been fixed now following an update to F18 at the time and with Fedora 29 they are looking at once again trying Liberation Fonts 2 by default...
