AMD Navi 10 Firmware Finally Lands In The Linux-Firmware Tree

While AMD has provided open-source Radeon RX 5700 series (Navi 10) support since launch and that code since worked into the various mainline code-bases from the Linux kernel to Mesa, one kink in their support has been their binary microcode images not being available from the reference linux-firmware.git location as needed to initialize the hardware. That Navi 10 firmware/microcode issue has finally been rectified with the images landing this morning.

Building A Linux HTPC / Storage Server With The SilverStone CS381

SilverStone recently sent over their CS381 chassis that has proven to be quite a versatile micro-ATX enclosure that can accommodate up to twelve hard drives (eight of which are hot-swappable) all while coming in at just 400 x 225 x 316mm. The SilverStone CS381 could work quite well as a Linux HTPC / DIY Steam Linux gaming living room PC or SOHO file server system with its compact size while offering immense storage potential. Here's more on the SilverStone CS381 and our build with using a Ryzen 5 3400G that is playing well under Linux with an ASUS B450 motherboard.

The Hardware FOSDEM Uses To Carry Out Linux Video Recordings Of Their Event

Not only is FOSDEM one of the best open-source/Linux events in the world for those who make the journey each February to Brussels, but they also for years now have done a masterful job at recording the different talks and developer room sessions. Each year gets better both for the event itself as well as the video recordings even with FOSDEM operating on a very limited budget due to the event being free to attend. For those curious about the hardware/software setup powering their video setup, here's an interesting blog post.

Noctua NH-L9a-AM4: A Very Low-Profile AMD Ryzen Cooler

When looking for a heatsink with a small stature for an AMD APU mini PC build for HTPC / file storage use-cases (more on that build in the next day or two), the Noctua NH-L9a-AM4 fit the criteria and so I went with that given the success with the many Noctua heatsinks we have used over the years. For those potentially interested in the NH-L9a-AM4 for an AMD APU like the new Ryzen 5 3400G or for lower-end Ryzen CPUs, I ran some benchmarks with this cooler.

Nouveau Finally Lands SPIR-V Support As Part Of OpenCL Push

Going back to December 2017 we've been tracking the Red Hat led effort on improving Nouveau's OpenCL compute support that involves adding NIR/SPIR-V support and improvements to the Clover Gallium3D state tracker. To much surprise, this morning the SPIR-V support for this open-source NVIDIA driver was merged for Mesa 19.3.

Ubuntu/Mir Developer Issues Porting Guide To Help Port MATE To Wayland

Canonical's Mir developers since re-shifting focus to serving as a Wayland compositor have been working with the likes of the GNOME2-forked MATE desktop environment to implement Wayland support using Mir. For helping those interested in porting MATE applications from X11 to Wayland, one of the Mir developers has now issued a porting guide.

AMD EPYC 7642 Benchmarks

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.

Clear Linux vs. Ubuntu 19.10 Video Encoder Performance On The Core i9 9900K

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.

GNOME 3.34 Should Be Hitting Clear Linux "Soon-ish"

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.

Running The AMD "ABBA" Ryzen 3000 Boost Fix Under Linux With 140 Tests

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.

Performance-Boosting DFSM Support Flipped On & Off For RADV Vulkan Driver

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.
