Ubuntu's Zsys Client/Daemon For ZFS On Linux Continues Maturing For Eoan

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.

DragonFlyBSD Pulls In The Radeon Driver Code From Linux 4.4

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.

ZFS On Linux Has Figured Out A Way To Restore SIMD Support On Linux 5.0+

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.

CompuLab Turns An 8-Core/16-Thread Xeon, 64GB RAM, NVIDIA Quadro RTX 4000 Into Fan-Less Computer

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!

Clear Linux Could Soon Be Faster Within Containers On AVX2 Systems

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.

Intel Is Still Working On Upstreaming SGX Enclave Support To Linux - Now At 21 Revisions

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.

AMDGPU DC Gets A Number Of Fixes For Navi & Other Clean-Ups

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.

Intel Speed Select Technology Comes To Linux With The 5.3 Kernel

With the in-development Linux 5.3 kernel is now support for Intel Speed Select Technology (SST) that was introduced as part of Cascade Lake processors. Speed Select Technology allows optimizing the system with per-core performance configurations to prioritize certain workloads while lowering the performance envelope for other cores.

The Massive DRM Pull Request With AMDGPU Navi Support Sent In For Linux 5.3

At 479,818 lines of new code and just 36,145 lines of code removed while touching nearly two thousand files, the Direct Rendering Manger (DRM) driver updates for Linux 5.3 are huge. But a big portion of that line count is the addition of AMD Radeon RX 5000 "Navi" support and a good portion of that in turn being auto-generated header files. Navi support is ready for the mainline Linux kernel!

Char/Misc Has A Bit Of Changes All Over For Linux 5.3

The char/misc changes with each succeeding kernel release seem to have less changes to the character device subsystem itself and more just a random collection of changes not fitting in other subsystems / pull requests. With Linux 5.3 comes another smothering of different changes.
