Fedora 37 Looks To Better Manage Its 175MB+ Of Linux Firmware Blobs
Fedora 37 Looks To Better Manage Its 175MB+ Of Linux Firmware Blobs
4 Hours Ago - Fedora - Linux-Firmware Binaries - 14 Comments

The size of the linux-firmware.git tree continues to grow with Linux continuing to support more and more modern hardware that is increasingly reliant upon firmware blobs for operation. Most Linux distributions like Fedora end up installing this entire set of Linux firmware files that can easily be 200~300MB even though most systems only use a few select files. With Fedora 37 later this year they are hoping to better deal with the situation by splitting up of linux-firmware and only installing sets of firmware packages depending upon the actual hardware in use.

HP Dev One With Ryzen 7 PRO 5850U Competes Well Against Intel's Core i7 1280P "Alder Lake P" On Linux
10 Hours Ago - Processors - 7 Comments

With my review last month of the HP Dev One laptop powered by an AMD Ryzen 7 PRO 5850U and running Pop!_OS I benchmarked it against various laptops I had locally with both AMD and Intel CPUs, including the likes of the very common Tiger Lake SoCs. At the time I hadn't any newer Alder Lake P laptops but now with a Core i7 1280P laptop in hand, here is a look at how that AMD Cezanne Linux laptop can compete with Intel's brand new Alder Lake P SoCs with the flagship Core i7 1280P.

While XWayland is normally used just for running root-less single applications like games within an otherwise native Wayland desktop, new patches from Red Hat that have been merged into the X.Org Server enhance XWayland's existing "root-full" mode of operation for allowing entire desktop environments and window managers to nicely function within the context of XWayland.

New Activity Around Adapting ACO Compiler Back-End For RadeonSI

As part of the work on the Mesa Radeon Vulkan "RADV" driver, Valve engineers developed the "ACO" compiler back-end that is now used by default for RADV and has shown to deliver better performance at least for RADV than using AMD's official AMDGPU LLVM shader compiler back-end. There has long been talk about adding ACO support to RadeonSI while in recent weeks there has been new code activity on that front.

A Dream Come True: Running Coreboot On A Modern, Retail Desktop Motherboard
A Dream Come True: Running Coreboot On A Modern, Retail Desktop Motherboard
30 June 02:00 PM EDT - Motherboards - 42 Comments

Over the many years of covering Coreboot (going back to when it was called LinuxBIOS!) on Phoronix the selection of supported motherboards has been rather unfortunate especially over the last decade. If wanting to run Coreboot on a system today it basically means running a Google Chromebook, using an outdated server motherboard or old Lenovo ThinkPad that has seen a Coreboot port, or out of reach to most individuals are various server motherboards that are reference platforms or board designs from hyperscalers. But over the past several months the folks at the 3mdeb consulting firm have carried out a terrific feat: porting their "Dasharo" downstream of Coreboot to a modern and readily available Intel desktop motherboard. I've been trying this out and it has worked out surprisingly well. Here are my experiences and benchmarks of Coreboot/Dasharo on this Intel Alder Lake motherboard.

Earlier this month Intel began committing Meteor Lake code to Coreboot for beginning to enable what will be the 14th Gen Core processors under this open-source system firmware solution used by Google Chromebooks and other use-cases. Intel engineers are ending out June with more Meteor Lake enablement code landing ahead of these processors expected to launch in 2023.

To this point Fedora out-of-the-box has been restricted to a filtered subset of Flathub packages when enabled via GNOME Software or GNOME Initial Setup. However, legal has now cleared Fedora for allowing unfiltered/unrestricted access to Flathub, allowing a far greater selection of Flatpaks to become available on Fedora Linux with the plan for this to begin with Fedora 37.

Stemming from last weeks Linux kernel patches suggesting an -O3 experimental option for all CPU architectures and Linus Torvalds rather quickly shooting it down, here are some fresh benchmarks looking at the Linux kernel performance when the kernel image is rebuilt with the -O3 optimization level rather than -O2.

For consumer Radeon GPUs the "Radeon Software for Linux" packaged driver version has been on the 22.10 series since the end of March. For AMD Radeon PRO professional/workstation graphics the advertised "Radeon Pro Software for Enterprise on Linux" driver is still the 21.Q4 driver from last December. AMD appears to be finally prepping to release the "22.20" packaged driver as the next feature release to this packaged AMD Linux driver stack for those not relying just on the upstream kernel and Mesa.

Hector Martin who has been leading the Asahi Linux effort for bringing up Linux on Apple Silicon recently received his new 2022 MacBook Pro 13-inch to begin porting Linux to Apple's new M2 SoC. While only started this week, he's already making significant progress. Fortunately, much of the existing M1-written Linux code can work for the M2 but some new drivers will need to be written before the new M2 Macs are fully usable on Linux.

With last week seeing AMDVLK 2022.Q2.3 released as an update to AMD's official open-source Vulkan Linux driver and it noting performance improvements, it was time for some fresh benchmarks of that driver up against Mesa's alternative "RADV" Vulkan driver. Here are some fresh benchmarks with an AMD RDNA2 GPU for seeing how RADV continues competing -- and usually outperforming -- AMD's own official open-source driver.

GCC-Rust Feedback Sought - Possibly Aiming For Upstream In GCC 13
27 June 02:10 PM EDT - GNU - GCC-Rust Upstreaming Talk - 49 Comments

The Rust-GCC front-end that allows Rust code to be compiled with the GNU Compiler Collection (GCC) could possibly be upstreamed for next year's GCC 13 compiler release but not necessarily complete at that stage. In any case, it's good seeing progress on Rust-GCC as an alternative to Rust's official LLVM-based compiler.

The Performance Cost To A Proposed Fedora 37 CFLAGS/CXXFLAGS Change
27 June 09:30 AM EDT - Software - 45 Comments

Coming about last week was a Fedora 37 change proposal to improve the profiling and debugging of Fedora packages but with possible performance costs. That suggested change is about adding "-fno-omit-frame-pointer" to the default CFLAGS/CXXFLAGS when building packages so the frame pointer is always available for improving the debugging/profiling of the stock Fedora packages. Unfortunately, it can come with significant performance costs as these benchmarks show.

Google engineers are working on the notion of "memory modes" for the Flash-Friendly File-System (F2FS) with the intent on introducing a "low memory" mode for storage devices that would alter its behavior. Presumably Google is working on this new F2FS feature for low-end Android devices.
