Among many different Linux/open-source benchmarks being worked on for the AMD EPYC "Rome" processors now that our initial launch benchmarks are out of the way are Linux distribution comparisons, checking out the BSD compatibility, and more. Some tests I wrapped up this weekend were seeing how recent Linux kernel releases perform on the AMD EPYC 7742 64-core / 128-thread processors...
While most major hardware vendors have been adopting LVFS+Fwupd for firmware updating on Linux, Linux PC vendor System76 has notably been absent from the party for a variety of reasons. Today they announced their new Firmware Manager project that bridges the gap between their lack of LVFS support and their own hosted firmware service...
Back in May we wrote about Oracle's initial plans for introducing an eBPF back-end to GCC 10 to allow this GNU compiler to target this general purpose in-kernel virtual machine. Up to this point LLVM Clang has been the focused compiler for eBPF but those days are numbered with Oracle on Friday pushing out the newest GCC patches...
The next Linux kernel version will expose the real-time sources of what's keeping the system awake via Sysfs compared to existing source information that previously was only available via DebugFS...
AMD's official open-source Vulkan driver code had fallen off its roughly weekly code push / release cadence with not having a new release in nearly three weeks, but that changed today with the availability of AMDVLK 2019.Q3.4...
Microsoft's newest specification is the "Component Firmware Update" that they envision as a standard for OEMs/IHVs to be able to handle device firmware/microcode updating in a robust and secure manner. While nice in theory, the actual implementation has a number of issues that complicate the process and could quickly evolve into another troubling specification from Microsoft in the hardware space...
Intel has released a new version of their SYCL compiler and run-time code for single-source C++ programming and allowing offloaded computations to accelerators via OpenCL...
Not directly related to the recent AMD Zen 2 BIOS update needed to fix an RdRand problem (though somewhat related in that the original systemd bug report for faulty AMD RdRand stems from these earlier CPUs), but AMD has now decided to no longer advertise RdRand support for Family 15h (Bulldozer) and Family 16h (Jaguar) processors under Linux...
While DTrace prospects for the Linux kernel are no longer viewed as magical or groundbreaking as they once were more than a decade ago, Oracle continues to work on its DTrace port to Linux and extending its reach beyond just their "Unbreakable Enterprise Kernel" for their RHEL-cloned Oracle Linux. Oracle now says they are working towards upstreaming more work as well as getting an eBPF-based implementation for the kernel...
Last week AMD sent out their initial Linux graphics driver support for next-gen Renoir APUs. Those Linux kernel bits will land with AMDGPU in the upcoming Linux 5.4 cycle while the RadeonSI changes were merged today marking that OpenGL support as a new feature for the upcoming Mesa 19.2...
While Arch Linux remains the gold standard for quality Linux documentation, Intel's Clear Linux has rolled out a new documentation web-site to assist new/existing users in making use of this performance-optimized and security-oriented Linux operating system...
EPEL 8.0 is now ready for users of Red Hat Enterprise Linux 8 and the eventual CentOS 8 for complementing the standard repositories with extra packages for what is found in Fedora...
The Blender 2.80 release arrived at the end of July that unfortunately was too late for using that big new release in our launch-day testing of AMD's EPYC 7002 "Rome" processors but as a follow-up here are AMD EPYC 7742 performance benchmarks up against the Intel Xeon Platinum 8280 Cascade Lake as well as the AMD EPYC 7601 2P. Blender 2.80 performance is the focus of this article along with some other renderer benchmarks.
Continuing on from the recent technical vision for the Qt6 tool-kit, The Qt Company has now announced their new high-level 3D API they are developing for this next major release of Qt...
GCC 4.2.1 has been out since 2007 and while there have been many big updates to the GNU Compiler Collection over the past decade, that version remains somewhat common in the BSD land due to being the last version under the GPLv2 license. GCC 4.2.2 and newer switched over to GPLv3+ and that is why several BSDs have stuck to using GCC 4.2.1 or at least keeping it in their base repository. But now for FreeBSD 13, this old version of GCC is set to be retired with FreeBSD already being quite focused on LLVM Clang as its default compiler while also offering newer GCC versions via its package management system...
It's now been one week since the launch of AMD's EPYC Rome processors with up to 64 cores / 128 threads per socket and better IPC uplift compared to their previous-generation parts. Rome has outperformed Intel Xeon Scalable CPUs in their class while offering better power efficiency and way better performance-per-dollar. One of my favorite metrics has been how quickly the new EPYC 7742 2P can build the Linux kernel...
With TrueOS (formerly PC-BSD) no longer focused on delivering a quality BSD desktop as they once did, while there still are options out there for a desktop-focused BSD like MidnightBSD, for those wanting to use a vanilla FreeBSD installation can now setup a desktop easier using a new script...
The Apache Software Foundation has published their 2019 fiscal year report highlighting their more than 350 open-source projects/initiatives and this also marks their 20th anniversary...
Up until today the newest Linux kernel version supported by the official Reiser4 out-of-tree file-system driver patch was Linux 5.0, but that has now changed with the belated Linux 5.1 kernel support arriving as well as a separate patch for Linux 5.2 kernel support...
With the Raspberry Pi 4, a passive heatsink is an absolute minimum for running this new ARM SBC unless you want to deal with potentially drastic performance limitations based upon your operating conditions. However, if you will be enduring the Raspberry Pi 4 with significant load for any measurable length of time, an active cooler is almost warranted or otherwise a very capable passive cooler. In this article we're looking at the Raspberry Pi 4 performance with a Fan SHIM as an active fan designed for running on the Raspberry Pi off the GPIO pins as well as the FLIRC as a metal case that passively cools the device.
NVIDIA this morning introduced their 435 Linux driver series currently in beta form with the release of the 435.17 Linux build. With this new driver comes finally the best PRIME/multi-GPU support they have presented to date...
The Khronos Group has posted their material from the SIGGRAPH 2019 graphics conference and includes some interesting updates on Vulkan and their ongoing efforts...
Similar to the recent upstream Linux kernel discussions over the poor Linux desktop experience when in memory pressure situations particularly with systems having limited amounts of RAM, Fedora developers are discussing ways to improve this experience as well...
Queued now for Linux 5.3 and also marked for back-porting to existing kernel stable series is a fix to address distorted and crackling analog audio input that has affected AMD systems for at least the past two years with certain Realtek audio codecs...
At $39 to $66 USD depending upon model, the ROCK Pi 4 is evolving to offer nice open-source support down to the Arm Mali graphics thanks to the Panfrost Mesa driver and also works nicely with Wayland...
Last week was the Intel Gallium driver one line patch to boost performance by 1%. Today's code churn within Mesa for Intel's open-source Linux graphics drivers were larger but also with a more profound performance impact with some workloads now being faster by around 20%. Making this more exciting is that today's round of driver optimizations apply to the very common and mature "Gen 9" graphics hardware...
AMD Mesa lead developer Marek Olšák has landed a set of improvements to the TGSI-to-NIR pass today for Mesa 19.2 to enhance the RadeonSI driver's support for using this intermediate representation...
One month ago we were told that AMD released a BIOS fix to their motherboard partners for addressing the systemd boot issue with Ryzen 3000 series processors that stems from an RdRand instruction issue. Finally over the past week we've seen motherboard vendors pushing out BIOS updates for the prominent motherboards and indeed this takes care of the issue...
With last week's dramatic EPYC "Rome" launch where AMD has blown past Intel Xeon "Cascadelake" performance in a majority of server benchmarks, helping the successful launch of these Zen 2 server processors has been Intel's repeated delays of 10nm/Icelake CPUs and also the Spectre / Meltdown / Zombieload / Foreshadow mitigations. Out of curiosity, I've run some unmitigated benchmarks for the various relevant CPU speculative execution vulnerabilities on both the Intel Xeon Platinum 8280 Cascadelake and AMD EPYC 7742 Rome processors for seeing how the performance differs.
We have seen Intel's compiler gurus contributing new enablement patches for Tiger Lake support with GCC 10 due out next year while now they have also landed their initial Tiger Lake support into the LLVM Clang 10 code compiler also due out in H1'2020...
It was just yesterday that Vulkan 1.1.118 was released with two new extensions while now this Monday morning Vulkan 1.1.119 was released as a third extension was accidentally left out of yesterday's weekly revision...
Sway and WLROOTS creator Drew DeVault on top of his several open-source projects has also been working on improving the VR infrastructure support on Wayland as part of contract work for Status.im. The secure communication company is looking to build a Wayland-driven VR workspace but for that the VR headset support on Wayland needs to be improved...
