IO_uring is designed to deliver fast and efficient I/O operations thanks to a re-designed interface introduced in Linux 5.1 with various efficiency improvements compared to the kernel's existing asynchronous I/O code. But it turns out there was a big bottleneck within the current IO_uring code up until now...

Adding to the list of new features for systemd 243 is another last-minute addition to this growing init system... Systemd picked up a new service and while some may view it as bloat, should be quite practical at least for those encountering kernel crashes from time to time...

One of the new features to the RDNA architecture with Navi is support for single cycle issue Wave32 execution on SIMD32. Up to now the RadeonSI code was using just Wave64 but now there is support in this AMD open-source Linux OpenGL driver for Wave32...

The Arm SoC/platform changes arrived a bit late to the Linux 5.3 merge window ending this weekend.

While the survey is being put out by Intel's performance-oriented Linux distribution, users of any Linux platform are encouraged to participate...

Back in May there were the plans shared by Red Hat's Matthias Clasen to work out some improvements to the Pango layout engine library after going fairly stale in recent years. That work is coming to fruition with a Pango 1.44 release looking like it will be here soon with new features...

Zstd 1.4.1 is out today as a maintenance release to Facebook's Zstandard compression algorithm but with this update comes even more performance optimizations...

With last week's big DRM pull request for Linux 5.3 that brought Navi support most notably on the AMD side while Intel received HDR display support, continued Icelake/Gen11 work, and more, there weren't any changes to the open-source NVIDIA "Nouveau" driver. It was another unfortunate cycle of no major improvements for the Nouveau driver but at least sent out today were a set of new "fixes" for this driver that remains crippled on Maxwell GPUs and newer...

Wayland's Weston compositor for the past year has provided a remoting plug-in for virtual output streaming that was built atop RTP/GStreamer. Now though a new plug-in has landed in the Weston code-base making use of Red Hat's promising PipeWire project...

While the Linux 5.3 kernel merge window isn't even over until this weekend when it will kick off with 5.3-rc1 and headlining new features like Radeon RX 5700 series support, AMD has already sent in a batch of AMDGPU/AMDKFD fixes. Making these fixes notable are some early fixes around the new open-source Radeon RX "Navi" support...

One of the first PCIe Gen 4 NVMe SSDs to market has been the Corsair Force MP600. AMD included the Corsair MP600 2TB NVMe PCIe4 SSD with their Ryzen 3000 reviewer's kit and for those interested in this speedy solid-state storage here are some benchmarks compared to various other storage devices on Ubuntu Linux.

Looking ahead to Ubuntu 19.10 as the cycle before Ubuntu 20.04 LTS, one of the areas exciting us with the work being done by Canonical is (besides the great upstream GNOME performance work) easily comes down to the work they are pursuing on better ZFS On Linux integration with even aiming to offer ZFS as a file-system option from their desktop installer. A big role in their ZoL play is also the new "Zsys" component they have been developing...

For those making use of the Ceph fault-tolerant storage platform, a number of updated kernel bits are landing in Linux 5.3...

While the Linux 4.4 kernel is quite old (January 2016), DragonFlyBSD has now re-based its AMD Radeon kernel graphics driver against that release. It is at least a big improvement compared to its Radeon code having been derived previously from Linux 3.19...

It's been over one year since the release of Latte Dock 0.8 as this KDE-aligned desktop dock while now the v0.9 release isn't too far away...

At the start of the month we reported on out-of-tree kernel work to support Linux on the newer Macs. Those patches were focused on supporting Apple's NVMe drive behavior by the Linux kernel driver. That work has been evolving nicely and is now under review on the kernel mailing list...

Those running ZFS On Linux (ZoL) on post-5.0 (and pre-5.0 supported LTS releases) have seen big performance hits to the ZFS encryption performance in particular. That came due to upstream breaking an interface used by ZFS On Linux and admittedly not caring about ZoL due to it being an out-of-tree user. But now several kernel releases later, a workaround has been devised...

Three years ago we checked out the CompuLab Airtop as a high-performance fanless PC. Back then it was exciting to passively cool an Intel Core i7 5775C, 16GB of RAM, SATA 3.0 SSD, and a GeForce GTX 950 graphics card. But now in 2019 thanks to the continued design improvements by CompuLab and ever advancing tech, their newly-launched CompuLab 3 can accommodate an eight-core / sixteen-thread Xeon CPU, 64GB of RAM, NVMe SSD storage, and a NVIDIA Quadro RTX 4000 graphics card without any fans!

For several generations now of Intel graphics there have been the GuC/HuC firmware binaries while beginning with Icelake "Gen 11" graphics those binary blobs will be loaded by default...

Later this month marks two years since the release of OpenGL 4.6 and just ahead of that date it looks like Mesa could finally land its complete GL 4.6 implementation, at least as far as the Intel open-source graphics driver support is concerned...

While it would have been nice seeing this next systemd release sooner due to the Zen 2 + RdRand issue with systemd yielding an unbootable system (that is now also being worked around with a BIOS upgrade), the systemd 243 release looks like it will take place in the near future...

The past few months openSUSE developers have been working on enabling LTO by default for its packages while now finally with the newest release of the rolling-release openSUSE Tumbleweed this goal has been accomplished...

OPNsense, the FreeBSD-based pfSense-forked firewall offering that has continued experiencing increased adoption following the closure of m0n0wall, is out with version 19.7 as its newest feature update...

Longtime X.Org developer Alan Coopersmith who also maintains the X.Org stack for Oracle's Solaris has been trying to get out some updated X.Org modules with different code-bases having collected enough changes over the years to warrant new versions...

Coming soon to a kernel near you could be the removal of 32-bit Xen PV guest support as better jiving with Xen's architectural improvements and more of the Linux/open-source community continuing to shift focus to 64-bit x86 with trying to finally sunset 32-bit x86...

While Clear Linux as part of its standard bare metal installations has long defaulted to having an AVX2-optimized GNU C Library installed by default, it turns out that it wasn't part of the default os-core bundle as used by containers. That though is changing and should yield even better out-of-the-box performance when running Clear Linux within containers...

With the VirtIO standard for cross-hypervisor compatibility of different virtualized components there is a virtual IOMMU device that is now backed by a working driver in the Linux 5.3 kernel...

While Mageia 7 released at the start of July for this Mandrake/Mandriva-derived Linux distribution, out today is already Mageia 7.1 as a rush release to fix AMD Zen 2 support...

Thanks to the upstream work achieved by Red Hat engineers working on Fedora the past few cycles, Ubuntu 19.10 should have a flicker-free boot experience...

Intel Software Guard Extensions "SGX" have been around since Skylake for allowing hardware-protected (via encryption) memory regions known as "enclaves" that prevent processes outside of the enclave from accessing these memory regions. While supported CPUs have been out for years, the Intel SGX support has yet to make it into the mainline kernel and this week marks the twenty-first revision to these patches...

Canonical's Balint Reczey has announced the addition of a new ubuntu-wsl package that will be installed by default when running Ubuntu on Microsoft's Windows Subsystem for Linux (WSL) in order to provide better integration...

David Sterba sent in the Btrfs file-system updates on Monday for the Linux 5.3 kernel...

The past few weeks while AMD open-source developers were busy getting their Navi enablement code public and aligned for the Linux 5.3 merge window, the display core "DC" frequent code drops ceased. Every so often AMD developers volley their DC patches from their internal development trees to the public mailing list for queuing ahead of the next cycle. Now that Navi is out there and getting stabilized, they've issued a new set of DC patches and it's coming in heavy...
