While the Ryzen 9 3950X and 3rd Gen Ryzen Threadripper processors were reportedly on track for launching in October with updates as of a few weeks ago, today AMD announced a slight delay in launching these new processors...

Kicking off today in Berlin is the annual All Systems Go conference focused on systemd and other user-space components. Systemd lead developer Lennart Poettering presented on systemd-homed as a new component to systemd that is focused on improving home directory handling...

Since the AMD EPYC 7002 series "Rome" launch at the beginning of August, it's been known how AMD's top-end (aside from the newly-announced EPYC 7H12) EPYC 7742 easily outperforms the Intel Xeon Platinum 8280 in most real-world benchmarks. The EPYC 7742 not only outperforms the Xeon Platinum 8280 in raw performance but also at a significantly lower cost and it gets even better with the EPYC 7642. We have been testing the EPYC 7642 48-core processors and even there the performance is generally ahead of a Xeon Platinum 8280 while being about half the cost of that flagship non-AP Intel Xeon Scalable Cascadelake processor.

NetworkManager has shifted its threshold for a weak WiFi signal for when to begin searching for other WLAN networks. Up to now NetworkManager used a -80dBm threshold for when to roam for other network signals while now that has changed to find hopefully stronger network signals sooner...

Often when doing cross-distribution benchmarks, readers often comment on the performance of Clear Linux particularly for video encoding use-cases as surprisingly different from other distributions. Some argue that it's just over the default CPU frequency scaling governor or compiler flag defaults, so here is a look at that with Ubuntu 19.10 daily benchmarked against Clear Linux...

While just yesterday the big DRM feature pull was sent in for Linux 5.4, AMD has also volleyed out their initial batch of fixes for this next version of the kernel...

For those anxious to make use of GNOME 3.34 with its many own performance improvements atop Intel's performance-optimized Clear Linux rolling-release distribution, it looks like the wait is still going on for a few more days but is coming "soon-ish" to the platform...

The OpenZFS file-system could soon be seeing better data deduplication support...

Like the mostly mundane Btrfs and XFS changes with the Linux 5.4 merge window, the EXT4 file-system activity is mostly focused on fixes too but also new debugging ioctls...

Haiku as the open-source operating system that still maintains BeOS compatibility continues tacking on modern features and support for software well past the days of BeOS...

Last week AMD's AGESA "ABBA" update began shipping with a fix to how the boost clock frequencies are handled in hopes of better achieving the rated boost frequencies for Ryzen 3000 series processors. I've been running some tests of an updated ASUS BIOS with this adjusted boost clock behavior to see how it performs under Linux with a Ryzen 9 3900X processor.

It was just two days ago that Valve's performance-focused "ACO" shader compiler was submitted for review to be included in Mesa for the "RADV" Radeon Vulkan driver. Just minutes ago that new shader compiler back-end was merged for Mesa 19.3...

Most Linux gamers these days should be running at least quad-core systems so Mesa 19.3 has been updated to reflect that reality with the number of CPU threads used by their disk cache...

This week Microsoft not only open-sourced their C++ standard library (STL) but they have also now shipped Cascadia Code...

The Linux 5.4 block subsystem changes brings the new blk-iocost model...

Back in July of last year the RADV Vulkan driver enabled primitive binning and DFSM for this open-source Radeon Vulkan driver. Well, it thought it enabled DFSM support and paired with the binning did yield a minor performance benefit at the time for Raven Ridge APUs. But now it turns out the DFSM support wasn't properly wired up and is now addressed but is currently introducing a performance regression...

The mature XFS and Btrfs file-systems continue seeing more fixes and cleaning with the now in-development Linux 5.4 kernel...

Greg Kroah-Hartman began volleying his Linux 5.4 kernel pull requests today of the subsystems he oversees. The most significant of this morning's pull requests are the staging area changes that include the Microsoft exFAT file-system support...

For those wondering how well FreeBSD and DragonFlyBSD are handling AMD's new Ryzen 3000 series desktop processors, here are some benchmarks on a Ryzen 7 3700X with MSI MEG X570 GODLIKE where both of these popular BSD operating systems were working out-of-the-box. For some fun mid-week benchmarking, here are those results of FreeBSD 12.0 and DragonFlyBSD 5.6.2 up against openSUSE Tumbleweed and Ubuntu 19.04.

While NVIDIA doesn't contribute much open-source Linux driver code as it concerns their desktop GPUs (though they have been ramping up documentation), when it comes to Tegra/embedded is where they have contributed improvements and new hardware support to Nouveau and associated driver code in the past several years. NVIDIA's open-source Tegra/embedded contributions come as a result of customer demand/requirements. Their latest work is preparing to finally bring-up the "GV11B" Volta graphics found within last year's Tegra Xavier SoC...

In an interesting change of course, the open-source driver support for AMD Radeon Navi 12 and Navi 14 GPUs is being flagged as experimental and hidden behind a feature flag...

Last month we provided launch-day benchmarks of the AMD EPYC 7502 and 7742 under Linux in both 1P and 2P configurations for these exciting "Rome" Zen 2 server processors. For your viewing pleasure today is a fresh look at not only the EPYC 7502 and 7742 processors under the latest Linux 5.3 kernel but we've also expanded it to looking at the EPYC 7302 and EPYC 7402 processors as well with those processors recently being sent over by AMD. Under Ubuntu 19.04 with Linux 5.3, these four different AMD EPYC 7002 series SKUs were benchmarked along with some of the older AMD Naples processors and Intel Xeon Gold/Platinum processors for a fresh look at the Linux server performance.

Fedora 31 beta has released on time! It's not only on-time but it's also coming with many exciting updates...

Earlier this year Canonical announced they would be pulling 32-bit support from Ubuntu ahead of next year's 20.04 LTS. But following public backlash, they stepped back to provide 32-bit support for select packages. Today they announced the 199 32-bit packages that will continue to be supported through Ubuntu 20.04 LTS...

TrueOS changing direction was a disappointment back in 2018 with having done away with their desktop version that had been around for years since formerly being known as PC-BSD. But at least there are a few viable alternatives that continue advancing for a nice out-of-the-box BSD desktop experience like GhostBSD and MidnightBSD...
