NVIDIA Resizable BAR Performance - A Big Boost For Some Linux Games

Back in March NVIDIA announced they would be supporting the GeForce RTX 30 series with Resizable BAR support via a video BIOS update for supported systems. Recently I've been looking at the performance of a GeForce RTX 3080 once flashing the graphics card under Linux with Resizable BAR support and the performance is quite compelling for Vulkan-based games where this functionality is working.

Fedora Stakeholders Back To Discussing Raising x86_64 Requirements Or Using Glibc HWCAPS

While Red Hat Enterprise Linux 9 is dropping support for older x86_64 CPUs by raising the baseline requirement to "x86_64-v2" that roughly correlates to Intel Nehalem era processors and newer, so far Fedora has not changed its default. There was a proposal shot down last year for raising the x86_64 microarchitecture feature level while now that discussion has been restarted or alternatively making use of Glibc's HWCAPS facility for allowing run-time detection and loading of optimized libraries.

It's Good But Maybe Bad: LVFS Skyrockets With More Than 100k Firmware Updates In One Day

The Linux Vendor Firmware Service (LVFS) with Fwupd has been serving on average around 40k~50k firmware updates per daay to Linux users relying on this cross-vendor, open-source firmware distribution service with FWUPD for applying firmware updates under Linux. But yesterday its usage just skyrocketed with more than 100,000 firmware updates in a single day... That's great for adoption but the motivation for the mass firmware updates may be something rough on the horizon.

Blender 3.0 Likely Delayed 2 Months For Post-Lockdown Breather, Cycles X Might Land

The wildly successful Blender 3D open-source modeling software has been working hard towards its Blender 3.0 release but will likely now be proactively delayed to allow developers more time to relax with COVID-19 lockdowns/restrictions loosening, the possibility of developer meetups pre-3.0, and letting more changes flow into this big feature release.

AMD EPYC 7343 / EPYC 7443 Linux Performance

Since the AMD EPYC 7003 "Milan" series launch back in March we have carried out many benchmarks with their flagship processors like the EPYC 7763 and 7713 processors and some of the frequency optimized SKUs, but what about the performance lower down the product stack? Up for benchmarking today is a look at the AMD EPYC 7343 and 7743 processors in 1P and 2P configurations against other AMD EPYC Milan processors as well as Intel's Xeon Platinum 8380 Ice Lake processors.

Fedora Cloud 35 Approved To Use Btrfs By Default

Last month plans were published for Fedora Cloud 35 to use the Btrfs file-system by default, similar to Fedora Workstation using Btrfs by default for several releases. That plan has now been signed off on by FESCo allowing for this change to happen.

SUSE Linux Enterprise / openSUSE Leap Pursuing x86_64-v2 Optimized Libraries

In addition to the rolling-release openSUSE Tumbleweed looking at HWCAPS / x86-64 feature levels for being able to provide greater out-of-the-box performance by selectively loading more tuned libraries depending upon the CPU in use, SUSE Linux Enterprise / openSUSE Leap are also looking at offering similar functionality that may turn up in time for the next point release / service pack.

Mesa's New "Crocus" OpenGL Driver Is Performing Well For Old Intel Hardware

Landing this week in Mesa 21.2's development code is Crocus Gallium3D providing a new Intel OpenGL driver for i964 "Gem4" through Haswell "Gen7" graphics. While even Haswell graphics are showing their age these days, I couldn't help but to fire up a few benchmarks seeing how this new Crocus open-source OpenGL driver performs against the existing "i965" classic open-source driver for Linux systems.

Noctua Launches NH-P1 As High-End Passive CPU Cooler

For those that have been wanting to build a passively cooled PC or at least keeping the number of fans to a minimum, Noctua just officially announced the NH-P1 as their high-end passive cooler. It's a massive heatsink but aims to be able to cool higher-end AMD and Intel desktop processors.

GNU C Library Looking To Drop FSF Copyright Assignment Policy

The GCC compiler has long had a requirement that all contributors assign their copyright to the Free Software Foundation. Recently GCC dropped that copyright assignment policy and now the GNU C Library is looking at making a similar move.

Intel M.2 Modem Driver "IOSM" Queued Ahead Of Linux 5.14

As part of Intel's new M.2 modem push for EVO laptops and Chromebooks, open-source Intel engineers have been working on "IOSM" as their new M.2 modem driver and this code which has been in the works for months is set to see its debut with the Linux 5.14 cycle.

Google + Canonical Bring Ubuntu Pro To Google Cloud

At the end of 2019 "Ubuntu Pro" was announced as Ubuntu for Amazon's EC2 cloud with ten years of package updates/security, kernel livepatching, Canonical Landscape integration, and more. Google and Canonical are announcing today that Ubuntu Pro is now coming to Google Cloud.

GCC 11 Compiler Performance Benchmarks With Various Optimization Levels, LTO

Given the recent forum discussion stemming from the -O3 optimization level still too unsafe for the Linux kernel (in part due to older, buggy compilers) and some users wondering about the current -O2 versus -O3 compiler optimization level impact, here is a fresh round of reference benchmarks using GCC 11.1 on Fedora Workstation 33 looking at various optimization levels and optimizations tested on dozens of different application benchmarks to see the overall impact on performance.

ACPI Platform Runtime Mechanism Support Is Getting Underway For Linux

Platform Runtime Mechanism was incorporated into the ACPI 6.4 specification earlier this year and allows moving some system management interrupt (SMI) handlers out of the system management mode (SMM) "black box" and into the OS/VMM execution context. With Linux 5.14 initial work on ACPI Platform Runtime Mechanism is set to land.

Another Intel Sandy/Ivy Bridge Motherboard Now Works For Coreboot (ASUS P8Z77-V)

While Intel engineers have been working on Alder Lake support for Coreboot as with other recent CPU generations that open-source firmware/BIOS support remains focused on their reference boards with a particular focus on meeting necessary requirements for Google Chromebook devices. Sadly, there is not much or any in the way of consumer retail motherboard support at this point. For those looking for retail desktop motherboard support for Coreboot, aside from the open-source POWER9 systems out of Raptor Computing, on the x86_64 front it largely means using aging Intel and AMD platforms.

Linux 5.14 Mainline Should Work With The Raspberry Pi 400

Launched last November was the Raspberry Pi 400 as a Raspberry Pi Keyboard Computer with effectively a Raspberry Pi 4 SBC embedded within the keyboard and attached to a large aluminum block for cooling. It's a great little device and beginning with Linux 5.14 looks like it should be playing fine with the mainline kernel.

Intel Publishes Latest TDX Support Patches For Linux

Last year Intel detailed Trust Domain Extensions (TDX) as a new means of better protecting virtual machines with hardware-assisted isolation between VMs as well as from the VMM/hypervisor. Shortly after that Intel began posting TDX enablement patches and that work has continued while is still ongoing.
