  • Linux 5.17 Adds GPU Recovery Support For AMD Rembrandt APUs - Phoronix

    On top of all the GPU driver feature changes to merge last week, yesterday marked the first batch of "fixes" sent in to Linux 5.17 for the Direct Rendering Manager drivers. Notable from this batch of fixes is getting GPU recovery enabled for Yellow Carp / Rembrandt APUs.

    GPU recovery for these forthcoming APUs was sent in as a fix since at this stage it just needed to add a Yellow Carp check to a case statement. The rest of the code is already in place for handling GPU recovery on Yellow Carp. But from past experience, GPU recovery is very useful when encountering Radeon GPU hangs on Linux but thankfully those are far less common these days with the great shape of their open-source driver stack.

  • After Nearly Six Years, Dirk Hohndel Is Leaving VMware

    Wow! This is surprise!

    A week ago, Dirk Hohndel announced on LinkedIn that after five years and eight months he’s leaving VMware, where he’s been serving as a VP and as its chief open source officer. The decision was his, he said, and there’s nothing to indicate that it has anything to do with VMware’s newfound independence (the company was spun-off by its owner Dell in November).

  • Nintendo GameCube / Wii / Wii U Get Real-Time Clock Driver With Linux 5.17 - Phoronix

    The RTC subsystem changes have been submitted for the in-development Linux 5.17 kernel ahead of its merge window winding down this weekend.

    For those hobbyists interested in running Linux on Nintendo video game consoles, Linux 5.17 is set to introduce the "gamecube" RTC driver that provides real-time clock support for not only the Nintendo GameCube but also the Wii and Wii U hardware.

    The GameCube / Wii / Wii U all leverage a MX23L4005 chip with a clock and 64 bytes of SRAM storage. The new Linux driver provides support for using that chip as the real-time clock device with read/set support.

  • Intel Linux Driver Adds New DG2 "G12" Graphics Variant - Phoronix

    To date the Intel Linux graphics driver has supported Intel's DG2 "Alchemist" G10 and G11 sub-platforms/variants as the main designs to this point. However, at the end of last year we began seeing "G12" references surface in their compute stack and now the Intel open-source Linux kernel driver is formally preparing the DG2-G12 variant support.

    Posted a few minutes ago were the first Intel "i915" Linux kernel graphics driver patches for bringing up the new G12 sub-platform.

  • Return String From Function C++

    A way to identify a series of strings as a class member is specified in C++’s definition. The String class holds attributes as a stream of bits, with the ability to handle a single-byte character. In C++, we may retrieve a string, but we should still examine how the string will be retained and transferred. Because C++ returns elements on the heap, which has a finite amount of space, providing immense components will induce stack overflow issues that could result in errors and security flaws. If we can return a std::string object from the standard template library, we may provide a constant pointer to the string. Ascertain that the string is retained in static memory. This article outlines various approaches for returning a string from a C++ function.

  • How to round of Numbers in Java

    Java provides a built-in class known as Math class which belongs to the java.lang package. The java.lang.Math class provides numerous methods that are used to perform different numeric operations such as rounding of a number, finding square root, and so on. The Math class offers multiple methods to round off a number such as round(), ceil(), floor().

Emulate the VIC-20 home computer with Linux

Emulation is the practice of using a program (called an emulator) on a PC to mimic the behaviour of a home computer or a video game console, in order to play (usually retro) games on a computer. Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single non-technical user. Back in the 1980s, home computers came to the forefront of teenagers’ minds. Specifically, the Amiga, ZX Spectrum, and Atari ST were extremely popular. They were hugely popular home computers targeted heavily towards games, but they also ran other types of software. The Commodore VIC-20 is an 8-bit home computer that was released in 1980/1. It featured a MOS Technology 6502 CPU, with 20KB ROM and 5KB RAM although 1.5K of the RAM was used for the video display and aspects of the BASIC and kernal. It offered limited low-resolution graphics (176 x 184) with storage provided by cassette and floppy disk. Read more

  • How to set up your graphics card in Zorin OS - Real Linux User

    Most modern Linux distributions have out of the box outstanding support for most of the available hardware components, like your graphics card, printer and WiFi adapter. Even for many relatively new hardware technologies there is support with the help of Hardware Enablement. But it is always possible that the setup procedure doesn’t come up directly with the correct or most optimized drivers for your specific internal or external devices. In this article as part of my Zorin OS tutorial series I will focus on the support of graphics cards and will show you how to install or update graphics drivers in Zorin OS.
