the same shared sources as SLE 15 SP4...

UBUNTU 22.04 UPS THE PERFORMANCE FOR TUXEDO'S AMD RYZEN LINUX LAPTOP

Last month I published a review on the TUXEDO Aura 15 Gen2 laptop that is
powered by an AMD Ryzen 5000 series SoC and initially shipped with Ubuntu 20.04
LTS. But with Ubuntu 22.04 LTS now having been released -- and TUXEDO Computers
shifting over to Ubuntu 22.04 LTS -- here is a look at the performance uplift
that can be expected from this new Ubuntu long-term support version.

INTEL PREPARES RAPTOR LAKE CODE FOR COREBOOT

In addition to Intel already starting work on Meteor Lake enablement in
Coreboot, this week Intel open-source engineers have also been submitting more
code for Raptor Lake as the CPUs expected later this year as the successor to
Alder Lake...

GNOME'S MUTTER VARIABLE RATE REFRESH SUPPORT CLOSER TO BEING MERGED

Variable rate refresh (VRR / FreeSync / Adaptive-Sync) support for GNOME's
Mutter compositor is closer to being merged. The native back-end support for VRR
that has been in development the past two years is no longer considered a
work-in-progress and it's believed there are no longer any blocking issues that
would prevent this code from landing...

RT PATCHES UPDATED FOR LINUX 5.19-RC1 - REAL-TIME INCHES CLOSER TO THE FINISH
LINE

The real-time (RT) patch series still hasn't been mainlined but the patch delta
is slowly winding down with each new kernel version. Out today is the re-based
RT patch series for the recently minted Linux 5.19-rc1 with some of the prior
real-time patches having been upstreamed this merge window and other patches
re-based to work with the newest kernel code...

RED HAT ENTERPRISE LINUX 9.0 PERFORMING WELL, GREAT BENEFIT TO NEWER INTEL XEON
& AMD EPYC SERVERS

Last month RHEL 9.0 reached GA as the newest major update to Red Hat Enterprise
Linux. Since then I've been trying out RHEL 9.0 on a few servers. To little
surprise, especially for latest-generation Intel Xeon Scalable and AMD EPYC
servers, RHEL 9.0 is offering significant uplift compared to the existing RHEL8
series. Here are some Red Hat Enterprise Linux 9.0 benchmarks comparing the
performance to RHEL 8.6.

SUSE LINUX ENTERPRISE 15 SP4 RELEASED - SWITCHES TO NVIDIA'S OPEN KERNEL DRIVER,
ADDS AMD SEV-ES

In kicking off SUSECON, SUSE has announced the release of SUSE Linux Enterprise
15 Service Pack 4. Notable with SLE 15 SP4, SUSE is already switching to using
NVIDIA's open-source GPU kernel-mode driver that NVIDIA open-sourced last month
and is under active development and has a long road ahead before it's even
feasible for upstreaming into the mainline kernel...

enablement work by Intel engineers...

ARM LOOKING TO MAKE IT EASIER TO RUN DOCKER ON AARCH64 LINUX

While Docker can already run on AArch64 Linux, the mainline Linux kernel's
default configuration "defconfig" lacks a few features for allowing it to run
out-of-the-box. An Arm engineer is proposing adjusting those defaults to make it
more easily/straight-forward to run Docker on 64-bit Arm...

SDL ADDS A DIRECTX 12 RENDERER BACKEND

Somewhat surprisingly, the open-source SDL library that is widely used by games
for cross-platform handling and abstracting of various software interfaces has
added a Microsoft DirectX 12 renderer...

IKEY DOHERTY RETURNING TO WORK FULL-TIME ON SERPENT OS LINUX DISTRIBUTION

Ikey Doherty started the Solus Linux distribution then disappeared and wrote an
open letter on Phoronix about his absence, also was employed by Intel for a year
to work on their Clear Linux distribution, had a brief stint starting a
game/software development company, and then started the Serpent OS Linux
distribution. He's still been working on Serpent OS but then was working
full-time elsewhere but now has decided to return full-time to working on his
latest Linux distribution...

MACOS 13 ADDING ABILITY TO USE ROSETTA IN ARM LINUX VMS FOR SPEEDY X86_64 LINUX
BINARIES

In addition to announcing the M2 SoC, Apple used its WWDC keynote to also
announce macOS 13 "Ventura". One of the interesting technical changes with macOS
13 is the ability to use Apple's Rosetta software for speedy execution of Linux
x86_64 binaries running on ARM Linux VMs from Apple Silicon...

APPLE ANNOUNCES ITS NEW M2 PROCESSOR

Apple's WWDC keynote this year was used to announce the M2 processor alongside a
slew of other announcements...

looks like AMD will be punctually supporting the cross-vendor mesh shader
extension too...

LINUX 5.20 + MESA 22.2 TO ALLOW CONFORMANT MALI G57 OPENGL ES 3.1 SUPPORT

With Panfrost Gallium3D patches landing today into Mesa 22.2 and Panfrost DRM
kernel driver support slated to land for the Linux 5.20 cycle later this summer,
the Mali G57 GPU has conformant OpenGL ES 3.1 support on this open-source driver
and the first Mali GPU of the Valhall generation to have this achievement
following the Panfrost driver's successes for the older Bifrost and Midgard
architectures...

LINUX 5.19 FEATURES: AMD SEV-SNP + ZEN 4 PREP, INTEL TDX + IFS, LOONGARCH, BIG
TCP, APPLE M1 NVME

With the Linux 5.19 merge window complete, here is my usual look at all of the
interesting changes I've been watching for this next version of the Linux
kernel. Linux 5.19 is quite a big summer time upgrade to this open-source kernel
with many new and improved features coming for this kernel that will debut as
stable in late July.

LINUX 5.19 FROWNS ON X86/X86_64 LATE MICROCODE LOADING - "IT'S JUST LOTTERY &
BROKEN"

A last minute change sent in on Sunday and merged prior to Linux 5.19-rc1
disables late microcode loading by default for x86/x86_64 processors over its
sad state of affairs...

MORE OLD GLSL CODE IS GUTTED FROM MESA 22.2

It's not only the Linux kernel that's been seeing some spring cleaning but Mesa
developers have also been quite busy on working to remove some old, poorly
maintained code from their open-source 3D driver components...

PHORONIX TURNS 18 YEARS OLD FOR COVERING LINUX HARDWARE

It was eighteen years ago today that I started Phoronix.com to focus on Linux
hardware reviews. Back then it was difficult getting peripherals working under
Linux from 56k modems to printers and other components today where Linux support
can just be assumed. Open-source graphics drivers back then were also in their
infancy and lacking vendor support while NVIDIA was well regarded then for their
proprietary driver being at least featureful and performant. It's been quite a
journey...

LINUX 5.19-RC1 RELEASED WITH INTEL TDX, AMD SEV-SNP, LOONGARCH, BIG TCP & A LOT
MORE

Following a rather eventful Linux 5.19 merge window the past two weeks, Linus
Torvalds just released Linux 5.19-rc1. It's a great way coincidentally to mark
the end of the Phoronix 18th birthday...

HARDWARE TIMESTAMPING ENGINE SUBSYSTEM MERGED FOR LINUX 5.19

While just a day prior Linus Torvalds was questioning the proposed "HTE"
subsystem, today on this final day of the Linux 5.19 merge window he decided to
land this new subsystem...

POPULAR USB DWC3 LINUX DRIVER LIKELY TO "NEVER BE FINISHED" WITH CONTINUED
ADAPTATIONS

Greg Kroah-Hartman on Friday sent in the USB/Thunderbolt updates for the Linux
5.19 kernel that is seeing its merge window end today. With the USB updates,
Greg had some remarks on the DWC3 Linux driver that will likely "never be
finished" given that this USB IP is appearing in lots of hardware but not
consistently being implemented and thus continuing to require a lot of
adaptations on the driver side...

MICROSOFT SHIPS BIG UPDATE TO THEIR CBL-MARINER 2.0 LINUX DISTRIBUTION

Last month Microsoft published their first production release of CBL-Mariner 2.0
as an updated version of their in-house Linux distribution used for a variety of
purposes from Windows Subsystem for Linux to Azure. This week Microsoft released
a rather hefty stable update to their CBL-Mariner 2.0 distribution...

APPLE EFUSE DRIVER, INTEL HABANA LABS DRIVER IMPROVEMENTS LEAD CHAR/MISC IN
LINUX 5.19

Greg Kroah-Hartman on Friday submitted the "char/misc" changes for the Linux
5.19 kernel. Char/misc continues to be the "catch all" area of the kernel for
drivers and code not fitting formally within other kernel subsystems. Leading on
this front for Linux 5.19 is the introduction of the Apple eFuse driver for M1
systems and Intel-owned Habana Labs continues improving their AI accelerator
driver...

FEX-EMU 2206 RELEASED FOR ENJOYING X86/X86_64 APPS & GAMES ON ARM

FEX-Emu 2206 has been released as the newest version of this user-space,
open-source software for being able to run x86/x86_64 applications and games on
AArch64 (Arm) hardware...

ASAHI LINUX CELEBRATES FIRST TRIANGLE ON THE APPLE M1 WITH FULLY OPEN-SOURCE
DRIVER
