MySQL 8.1 is available today with the community server builds now available for this latest major update to this popular SQL database server...

There's a lovely new Linux kernel patch series out that's big in working on a major clean-up of the x86 APIC code (or "decrapification" as it's called in the patches) and also bringing up for discussion the idea of killing off x86 32-bit support. It's unlikely the x86 32-bit support will be removed right now, which is "just museum pieces", but as an alternative would be making it SMP-only to at least remove the uni-processor code paths...

While Intel Arc Graphics continue enjoying performance optimizations with the open-source Linux graphics driver stack, the major limitation facing Arc Graphics on Linux right now for gamers is the lack of sparse residency support that is needed for running many newer games on Linux with Intel graphics -- particularly newer Windows D3D12 titles running on Linux via Valve's Steam Play. It's been a long known limitation and will hopefully be addressed once the Intel Xe kernel driver is introduced, but at least as an interim solution there is now "fake" sparse support being implemented...

A set of 35 patches were posted on Sunday for introducing ARM64 Guarded Control Stack (GCS) support to the Linux kernel. This is akin to x86 Shadow Stack support for hardware-protected stacks of return addresses to help fend off ROP attacks...

Merged for Linux 6.5 was initial MIDI 2.0 support for the necessary USB audio and raw MIDI drivers to support this major MIDI update. Being worked on now for merging into a future kernel release is the USB gadget driver support around MIDI 2.0...

With the Intel Xeon Max testing at Phoronix that's been ongoing so far for the past month on Phoronix has all been done within the Supermicro Hyper SuperServer SYS-221H-TNR rackmount server. This 2U dual socket platform for 4th Gen Xeon Scalable "Sapphire Rapids" processors has been working out well and provides a robust feature set while working out well for all of my Linux testing thus far.

The High Precision Event Timer (HPET) has long been a source of issues for Linux developers and it turns out systems relying on HPET rather than the CPU's TSC have in recent months suffered significant performance degradation with the Mesa OpenGL driver code...

Back in April I pointed out some new AMD patches at the time for enabling a new "Dynamic Boost Control" feature that hasn't been widely talked about by AMD yet for allowing more frequency/power controls around Ryzen SoCs. But making this power/performance feature controversial is that it requires authentication with the AMD Platform Security Processor (PSP) for activation with user-space blobs for tapping this greater control of the hardware. This AMD Dynamic Boost Control feature now looks like it is ready for merging into Linux 6.6...

Similar to the Dell WMI system management driver and Lenovo's Think-LMI driver, the HP-BIOSCFG driver now poised for introduction in Linux 6.6 allows for managing and configuring BIOS settings on capable HP laptops/desktops from under Linux itself...

Ahead of the Linux 6.5-rc2 release tomorrow there was a set of x86/x86_64 kernel changes merged overnight to deal with some weaknesses in the kernel's Control Flow Integrity (kCFI) / FineIBT (Indirect Branch Tracking) code...

With all the news in recent weeks following Red Hat's decision to limit access to RHEL sources that in turn lead to changes for AlmaLinux, finding new ways to obtain sources at Rocky Linux, interesting statements from Oracle, and even SUSE forking RHEL. The public RHEL sources now will basically be the upstream CentOS Stream code for which future Red Hat Enterprise Linux versions are ultimately based. The CentOS Project issued a new statement on Friday...

Earlier this month brought the release of systemd 254-rc1 with a new soft-reboot mechanism, officially deprecating System V scripts, a new systemd-battery-check process that runs at boot to check any system battery level status, and various other changes. On Friday systemd 254-rc2 was released with a few more changes...

With Red Hat now restricting access to the RHEL source repositories, AlmaLinux and other downstreams that have long provided "community" rebuilds of Red Hat Enterprise Linux with 1:1 compatibility to upstream RHEL have been left sorting out what to do...

Similar to what I have shown with the Ryzen 9 7950X AVX-512 desktop performance and AMD EPYC 9004 series AVX-512 server performance, the new Ryzen 7040 series mobile processors are exhibiting great AVX-512 performance for laptops. In today's article is a look at the performance impact when toggling AVX-512 capabilities for a Ryzen 7 7840U "Phoenix" SoC compared to toggling AVX-512 with prior Intel Tiger Lake and Ice Lake laptops that offer AVX-512.

Intel's Linux software engineers understand the annual GCC compiler release cadence well and acknowledge the importance of having tuned compiler support available at launch. Intel for years has tended to get their new CPU support and new ISA features upstreamed into GCC as well as LLVM/Clang well ahead of product launch so that by the time their new consumer and server CPUs are shipping, there tends to be support within compilers just not at their stable versions but already found in the likes of Ubuntu. With that said, today Intel engineers posted initial compiler patches for Lunar Lake and Arrow Lake processors...

While less than one week has passed since the Linux 6.5 merge window ended and 6.5-rc1 being issued, there is already the first set of drm-misc-next changes submitted to DRM-Next of early open-source graphics/display driver changes geared for Linux 6.6 later this year...

Now that the Linux 6.5 merge window ended this past weekend, here is the usual Phoronix overview that lists all the prominent new features and changes coming for this next version.

Last month AMD Linux kernel driver patches revealed a new feature called FreeSync Panel Replay that is basically an improvement over Panel Self Refresh (PSR) for laptop displays.
