While we are looking forward most to Icelake with the new "Gen 11" graphics, Intel has been working on Comet Lake for introduction this year as a Coffeelake derived successor to Whiskey Lake for desktops and mobile devices. The patches needed for Comet Lake graphics driver support on Linux are now pending...

Mesa 19.1 has added support for the GLX extension to create an OpenGL / OpenGL ES context that doesn't generate errors -- assuming the driver supports the likes of KHR_no_error. For applications/games acquiring their GL/GLES context in this no-error mode, it can yield possible performance benefits...

It's been a while since last running any P-State/CPUFreq frequency scaling driver and governor comparisons on Intel desktop systems, so given the recent release of Linux 5.0 I ran some tests for looking at the current state of affairs. Using an Intel Core i9 9900K I tested both the P-State and CPUFreq scaling drivers and their prominent governor options for seeing not only how the raw performance compares but also the system power consumption, CPU thermals, and performance-per-Watt.

It's been just one week since Linux 5.0 was christened followed this weekend by the first point release and now that brand new kernel is shipping to users of Intel's rolling-release Clear Linux platform...

While there is the MuQSS CPU scheduler that lives out of tree as a promising CPU scheduler for the Linux kernel, it is not alone. Another option has been the PDS scheduler while now its author, Alfred Chen, has announced another new CPU kernel scheduler option he has dubbed the BitMap Queue...

Fedora 30 is aiming to ship with the Wayland native version of Firefox by default rather than relying upon XWayland. This Wayland-native Firefox has long been offered in the Fedora repository but not used as the default browser. While it's not all squared away yet, more time has been granted to get it ready for this spring update to Fedora...

We are over half-way through the Linux 5.1 kernel merge window. While we've had many articles detailing the individual changes thus far of the new kernel, if you are unfortunately behind on your Phoronix reading, here's a quick look at some of what has been queued this far for this next major kernel update...

Up for discussion on the Linux kernel mailing list is adding support for the Secure Launch boot protocol to Linux. This is part of the recent efforts to supporting Linux in "secure" boot environments around Intel Trusted Execution Technology and AMD SKINIT platform security...

While nearly all Linux distributions have been mitigated against the Spectre and Meltdown CPU vulnerabilities for over one year, the performance ahead associated with these speculative execution vulnerabilities can vary. This is especially more so with the enterprise Linux distributions that are generally shipping on older kernel branches prior to where the initial kernel support was mainlined. With recent kernel releases we've also seen varying optimizations and other changes around the Spectre/Meltdown/L1TF mitigations. So for those wondering about the varying impact, here are some side-by-side benchmarks.

Sway 1.0 is now available for this independent Wayland compositor that is inspired by the i3 X11 window manager and has matured with quite an in-depth feature set as well as evolved along with its own "WLROOTS" Wayland library...

The latest work within Mesa 19.1 is for the Intel "ANV" Vulkan driver and that is dumping more shader information within the VK_EXT_debug_report extension. The output of that is then used by the Mesa developers' VKpipeline-DB utility for offline analysis...

While we are expecting to see more Intel Optane NVDIMMs this year that offer up persistent memory using 3DXPoint memory on the DDR4 bus for persistent storage, the Linux 5.1 kernel might pick-up support for treating this persistent memory back as traditional RAM if so desired...

Meson 0.50 is now available as the latest feature update to this increasingly used cross-platform build system that is powering the likes of many GNOME projects, many X.Org/FreeDesktop.org low-level software components, and other software that when paired with Ninja is known for its lightning fast build times and better cross-OS support compared to traditional alternatives...

The Panfrost Gallium3D driver has been quick to take form since it was merged to the Mesa 19.1 development code a month ago providing open-source 3D support for Arm Mali Midgard and Bifrost graphics hardware. The latest achievement for this Gallium3D driver in Mesa Git is being able to run with the yet-to-be-merged DRM kernel driver...

SIMPLE_LMK is a simple low-memory killer being worked on for potential upstreaming in the mainline Linux kernel in the future but for now is simply seeking comments on its design approach...

Back when kernel mode-setting (KMS) was originally talked about a decade ago one of the talked about possibilities of implementing a Linux "Blue Screen of Death" / better error handling when a dramatic system problem occurs. Such an implementation never really materialized but now in 2019 there is a developer pursuing new work in this area with a DRM-based kernel oops viewer...

The Lemote Yeeloong netbooks came out a decade ago and based on the MIPS Loongson 2F processor clocked up to 900MHz, offered up to 1GB of RAM, some models featuring an 8GB SSD, and driving the display was a Silicon Motion controller. The Yeeloong netbooks/laptops were even used by Richard Stallman for being open-source friendly and he used the devices as his own system for several years. Finally in 2019, better mainline Linux kernel support is being worked on...

A month ago we were first to report on Intel posting Linux graphics driver patches for "device local memory" as they prepare for the bring-up of their "Xe Graphics" discrete GPU hardware due out at some point in 2020. To no surprise, there are more patches out today as the Intel open-source developers begin pushing out more code restructuring work for bringing up graphics support past Icelake "Gen 11" graphics...

As a change in acknowledging the increasing Arm SoC core counts as more vendors take stabs at higher-end server chips, the default 64-bit Arm (ARM64 / AArch64) kernel image as of Linux 5.1 will default to supporting 256 CPUs compared to the current default limit of 64 CPU cores...
