GCC 11 Compiler Performance Benchmarks With Various Optimization Levels, LTO

Monday 14th of June 2021 01:30:00 PM
Given the recent forum discussion stemming from the -O3 optimization level still too unsafe for the Linux kernel (in part due to older, buggy compilers) and some users wondering about the current -O2 versus -O3 compiler optimization level impact, here is a fresh round of reference benchmarks using GCC 11.1 on Fedora Workstation 33 looking at various optimization levels and optimizations tested on dozens of different application benchmarks to see the overall impact on performance.

ACPI Platform Runtime Mechanism Support Is Getting Underway For Linux

Monday 14th of June 2021 12:00:00 PM
Platform Runtime Mechanism was incorporated into the ACPI 6.4 specification earlier this year and allows moving some system management interrupt (SMI) handlers out of the system management mode (SMM) "black box" and into the OS/VMM execution context. With Linux 5.14 initial work on ACPI Platform Runtime Mechanism is set to land...

Another Intel Sandy/Ivy Bridge Motherboard Now Works For Coreboot (ASUS P8Z77-V)

Monday 14th of June 2021 10:36:16 AM
While Intel engineers have been working on Alder Lake support for Coreboot as with other recent CPU generations that open-source firmware/BIOS support remains focused on their reference boards with a particular focus on meeting necessary requirements for Google Chromebook devices. Sadly, there is not much or any in the way of consumer retail motherboard support at this point. For those looking for retail desktop motherboard support for Coreboot, aside from the open-source POWER9 systems out of Raptor Computing, on the x86_64 front it largely means using aging Intel and AMD platforms...

KWinFT Going Through Code Refactoring, Working On WLROOTS-Based Usage

Sunday 13th of June 2021 05:30:03 PM
Announced last year was KWinFT as a fork of KDE's KWin to focus on improving the Wayland support more rapidly and incorporating other modern technologies. KWinFT has been making progress on advancing its code-base while in recent months it was seemingly more quiet. However, it turns out KWinFT is alive and well and has been going through some code refactoring while preparing for the next wave of feature work...

Linux 5.14 To Begin Enabling The Intel Graphics TTM Memory Management Bits for dGPUs

Sunday 13th of June 2021 11:07:47 AM
While a decade ago Intel's open-source Linux graphics driver engineers resisted TTM at the time and instead devised the Graphics Execution Manager (GEM) for kernel graphics memory management needs in its place, now with discrete graphics cards and dedicated video memory, Intel has been working on making use of TTM memory management for those purposes. With Linux 5.14 the initial bits are going to be there for using TTM by the Intel driver when running with discrete graphics having local memory...

Profile Guided Optimizations (PGO) Likely Coming To Linux 5.14 For Clang

Saturday 12th of June 2021 05:00:00 PM
Recently the mainline Linux kernel has seen a lot of improvements to its feature set when compiling it under LLVM's Clang rather than GCC as traditionally the only supported compiler. The most recent feature being brought to the Linux kernel when using Clang is finally allowing the use of compiler profile guided optimizations (PGO) for squeezing even greater performance out of the system by letting the compiler leverage the real-world profiles/metrics collected to make more informed code generation / optimization decisions...

Tiny i.MX8M Mini module also ships on dev kit with Digi XBee

Digi’s rugged “ConnectCore 8M Mini” module runs Linux or Android on an i.MX8M Mini with Digi TrustFence security, up to 2GB LPDDR4 and 8GB eMMC, and 802.11ac/Bluetooth 5.0. A dev kit offers mini-PCIe and Digi XBee expansion. Digi has launched a Digi ConnectCore 8M Mini module and development kit that feature NXP’s i.MX8M Mini and support for Digi XBee modules including cellular add-ons. The ConnectCore 8M Mini has the same 45 x 40 x 3.5mm dimensions as the i.MX8X based Digi ConnectCore 8X module from 2018. We missed a similarly sized, i.MX8M Nano based ConnectCore 8M Nano from 2019, which has many of the features of the ConnectCore 8M Mini but is limited to 1GB RAM instead of 2GB. Read more

Most Beautiful Linux Distributions

Today there is Linux distribution for every type of computer user present on this planet irrespective of their work. From a kid studying in school to a professional working in a multinational company, there is Linux distribution available for every user. Linux is an open-source operating system; developers worldwide use various open-source technologies to develop a new surprising fork of Linux. Everyone gets tired of looking at the same desktop every day; we need something refreshing at a fixed interval of time to keep ourselves fresh and focused on work. Especially if you’re working on Windows or Mac OS, you get tired of the same look and layout because they generally possess the same look and feel even after some major updates. Read more

Best OCR Apps for Linux

This article will cover a list of useful “Optical Character Recognition” software available for Linux. An optical character recognition (OCR) software attempts to detect text content of non-text files whose content cannot be selected or copied but can be viewed or read. For instance, an OCR software can identify text from images, PDF or other scanned documents in digital file formats using various algorithms and AI based solutions. These OCR software are especially useful for converting and preserving old documents as they can be used to identify text and create digital copies. Sometimes the identified text may not be 100% accurate but OCR software removes the need for manual edits to a great extent by extracting as much text as possible. Manual edits can be made later to improve accuracy further and create one-to-one replicas. Most OCR software can extract text into separate files, though some also support superimposing a hidden text layer on original files. Superimposed text allows you to read content in original print and format but also allows you to select and copy text. This technique is specially used to digitize old documents into PDF format.
