Phoronix

Current Linux block subsystem maintainer Jens Axboe started out in the late 90's taking over maintainership of the Linux kernel's CD-ROM driver code. However, as he's busy these days with IO_uring and other prominent I/O activities for Linux, he's hoping someone interested and capable would want to take over the Linux kernel's CD-ROM code...

A number of Phoronix readers have been asking about some fresh file-system comparisons on recent kernels. With not having the time to conduct the usual kernel version vs. file-system comparison, here are some fresh benchmarks looking at the Btrfs, EXT4, F2FS, and XFS file-system benchmarks on a speedy WD_BLACK SN850 NVMe solid-state drive...

The Linux kernel has already sported SM4 cipher algorithm implementation optimized for AES-NI and AVX while now an Alibaba engineer has contributed an AVX2 optimized variant for even greater performance...

For nearly the past decade there has been calls for deprecating the Liux kernel's frame-buffer "FBDEV" device code though the code remains within the kernel. While these days most display drivers are DRM-based even in the embedded world, a lot of FBDEV code still ends up in kernel builds even when just wanting to use DRM's FBDEV emulation layer. But a patch proposal out of Red Hat would further split-up the FBDEV core support to allow less of it to be built...

On top of all the PCI IDs in place already for the AMDGPU Linux kernel graphics driver, another 17 PCI IDs were added in a new patch for this open-source Radeon graphics driver...

Going back to June of last year there has been work on Intel bringing up Advanced Matrix Extension (AMX) that will debut with next-gen Xeon "Sapphire Rapids" processors as a new programming paradigm. Over the past year they have published patches for the Linux kernel and open-source toolchains with GCC and LLVM Clang. One year later, the AMX kernel patches are up to their tenth revision but will miss out on the imminent Linux 5.15 merge window...

It was just last month that the Linux kernel saw a pipe code change to address a user-space regression due to the kernel's policy about not breaking the user-space even if that non-kernel code is in the wrong. A similar kernel regression fix was merged today...

Loongson this summer rolled out their 3A5000 processors built on their own "LoongArch" ISA. While the company continues claiming that LoongArch is "not MIPS", the Linux kernel code they continue proposing for the mainline Linux kernel points to it being a close facsimile to MIPS...

Earlier this year when Clang LTO support was added for Linux 5.12 that link-time optimization support wasn't done solely for squeezing out greater performance but also because it's a prerequisite for making use of Clang's Control Flow Integrity (CFI) functionality. Google engineers have now sent out their latest set of patches for bringing up Clang CFI support within the Linux kernel...

QEMU 6.1 is out as the newest feature release to this widely-used, open-source Linux virtualization component...

While there is still two months to go until the Ubuntu 21.10 "Impish Indri" release, since the feature freeze has now begun I've started some early testing of this next Ubuntu release. So far things are looking good as a nice upgrade over Ubuntu 21.04 and prior. Here is the first round of Ubuntu 21.04 vs. 21.10 development tests using an AMD Ryzen 9 5950X with Radeon RX 5700 XT graphics.

Last month I wrote about the proposed reflink support for Wine that would provide significant space savings for those having multiple Windows games/applications on Linux installed where Wine and derivatives like Crossover and Steam Play (Proton) generally maintain a separate "prefix" per software installation. Fortunately, that reflink support continues to be worked on for Wine where it can lead to savings up to several hundred megabytes per Wine prefix...

GTK 4.4 is out as the latest stable update to the GTK4 open-source toolkit...

Zink as an OpenGL-over-Vulkan API implementation living within Mesa merged its sub-allocator code that could deliver 10x the performance for some games. Plus it also landed OpenGL compatibility context support for getting more games working now with this open-source GL-on-VLK solution. Given the progress made in Mesa Git over the past week, here are some fresh benchmarks now for how the performance stands across various games and benchmarks.

Going on three years now there have been proposed patches for allowing per-client GPU engine statistics for being able to show on a per-game/application level how many resources across 3D/blitting/video engines are being consumed. The patches continue to be revised but sadly will be missing out on the imminent Linux 5.15 kernel merge window...

While Habana Labs has been known for their open-source and upstream Linux kernel driver for their AI training/inference accelerators with that code they had been working on as a start-up even before being acquired by Intel, it's continued to cause friction that they rely in user-space on closed-source components like their compiler. That in turn is again causing problems for changes that the Habana Labs kernel driver planned to land with the upcoming Linux 5.15 cycle...

Running Linux on the Apple M1 with various out-of-tree patches is now capable of booting to a GNOME desktop albeit lacking any OpenGL/graphics acceleration...
