Linux 5.11-rc3 Released Following A Post-Holiday Ramp-Up

While Linux 5.11-rc2 was tiny due to the holidays , with developers and testers returning to work the Linux 5.11-rc3 release that was just issued is much bigger.

Linus Torvalds wrote of the Linux 5.11-rc3 release a few minutes ago, " the final rc3 ends up being on the bigger side as rc3s go. Not "beating records" big, but certainly bigger than average. So instead of some slow start due to the

Changing One "If" To "While" Caused An Unexpected Shift In A Kernel Benchmark This Week

Several months back you may recall that Linux 5.9 kernel regression we noted that in turn was bisected to code introduced by Linus Torvalds around page lock fairness. That was ultimately worked out in time with allowing a control over the page lock (un)fairness to address the regressed workloads while being fair enough to satisfy his original change. But now this week for Linux 5.11, Linus Torvalds has again altered the behavior. It then ended up causing a PostgreSQL database server performance regression but fortunately any impact should

Linux Kernel Developers Discuss Dropping A Bunch Of Old CPUs

With Linux 5.10 having shipped as the latest Long Term Support (LTS) release to be maintained for at least the next five years, a discussion has begun over dropping a number of old and obsolete CPU platform support currently found within the mainline kernel. For many of the architectures being considered for removal they haven't seen any new commits in years but as is the case once proposals are made for them to be removed there are often passionate users wanting the support to be kept.

Mesa 21.0 Is Now Working With Haiku OS For Software OpenGL Rendering

BeOS-inspired Haiku OS can now run with Mesa 21.0 well using the latest development code.

A number of patches worked on for Haiku OS back for Mesa 20.x were freshened up and with some extra tweaking and code cleaning those patches have now been merged for Mesa 21.0. This includes factoring out a lot of the OpenGL legacy dispatch code and a lot of cleanups around the Softpipe driver handling.

With Mesa 21.0-devel as of today, it's at

NVIDIA Windows/Linux Graphics Drivers Hit By A Series Of Security Vulnerabilities

With this week's R460 driver release also comes a number of security updates. Several security issues have been patched in both the NVIDIA Windows and Linux graphics driver components.

The set of 2021 CVEs " addresses issues that may lead to denial of service, escalation of privileges, data tampering, or information disclosure. "

Among the vulnerabilities are a kernel ioctl through which user-mode clients can access legacy privileged APIs, the kernel driver not completely honoring file-system permissions for GPU device-

PHP 8.0 Is Too Fresh For Fedora 34 That It Will Be Punted To F35 In The Autumn

While Fedora has been well known for years in always shipping the very latest packages in its distribution as of release even if it means using the likes of a near-final GCC compiler pre-release, developers have decided to postpone the shipping of PHP 8.0 until the autumn with their Fedora 35 release.

PHP 8.0 was released at the end of November with many new features and changes . While it released in plenty of time for getting it into Fedora 34 that is due out this spring,

Intel Vision Processing Unit Patches Updated For The Linux Kernel

As part of Intel's lengthy " Keem Bay " upstreaming for Linux as their latest-generation Movidius VPU offering, now that much of the core infrastructure bits are all mainlined, the latest focus has been on their Vision Processing Unit enablement.

The Intel Vision Processing Unit upstreaming is quite big and includes new xlink-pcie, xlink-ipc, and xlink-core drivers as part of the effort. This VPU was developed through Intel's acquisition of Movidius and can be used for computer vision processing on a locally

Intel Preparing New Driver Option To Disable GPU Security Mitigations

Stemming from the renewed attention this week of Haswell GT1 graphics being broken for the past half-year under Linux with the latest versions of the kernel, a revised patch was sent out to restore that graphics support for low-end Haswell Celeron/Pentium processors. As part of that, a new option is being introduced to allow disabling security mitigations of the Intel graphics driver.

This patch was sent out on Saturday that fixes up the Haswell GT1 support following the public attention this week over the low-end Haswell

AMD Making Progress On HMM-Based SVM Memory Manager For Open-Source Compute

This week AMD engineers published their initial code for the AMDGPU/AMDKFD Linux kernel driver for providing a Heterogeneous Memory Management based Shared Virtual Memory (SVM) memory manager that ultimately will be used by their ROCm compute stack.

Linux's HMM implementation came together over the years and of the interest to many vendors. HMM allows for GPU discrete video memory and other (non-conventional) device memory to be integrated into regular code paths and allowing memory pointers to work across devices / memory address spaces. HMM is a key

Alibaba's MNN Deep Learning Framework Continues Squeezing More Performance

Alibaba developers released an updated version of their "blazing fast" lightweight deep learning framework MNN, or the Mobile Neural Network.

This deep learning framework that has been "battle-tested by business-critical use cases in Alibaba" continues working to exploit every bit of possible performance.

With the 1.1.1 release noting more optimizations for "speed up" as well as bug fixes, our MNN test profile for benchmarking with the Phoronix Test Suite and OpenBenchmarking.org was updated against the new version.
