Rock Pi S Is A Dirt Cheap Mini Computer That Runs Linux

Linux
Hardware

Just yesterday, we were greeted with the release of the brand-new Raspberry Pi 4. The new model ships with up to 4GB LPDDR4 RAM, making the device an even more convincing replacement for an entry-level laptop. While the 1GB base model still costs $35, the top-end version costs $55.

Even though owning a Rasperry Pi 4 won’t break your pocket, what if I tell you the latest Rock Pi S from Radxa costs just $9.90 and runs Linux-based operating system?

The open-spec “Khadas Vim3” SBC is on pre-order for $100 (2GB/16GB) or $140 (4GB/32GB) with an Amlogic A311D with a 5-TOPS NPU instead of the planned S922X. Other features include 40-pin GPIO, HDMI 2.1, MIPI-DSI and -CSI, USB 3.0 and Type-C, and M.2 with NVMe.

Shenzhen Wesion’s Khadas project announced the Khadas Vim3 in mid-May with the same Amlogic S922X found on Hardkernel’s Odroid-N2. Earlier this month it announced the June 24 launch date along with pricing of $70 (2GB/16GB) and $100 (4GB/32GB). Last week, however, a blog post announced a switch to the similar, but more powerful and AI-enhanced Amlogic A311D. Today, the board went on pre-order at $100 and $140 with the A311D, with shipments expected on Aug. 10.

Intel UMWAIT Support Queued For Linux 5.3 - New Feature For Tremont Cores

Filed under
Linux
Hardware

Adding to the growing list of features for the upcoming Linux 5.3 kernel is now Intel UMWAIT support for better power-savings.

UMWAIT is a new feature for Intel Tremont CPUs cores. UMWAIT can help enhance power savings during idle periods with "user mode wait" functionality. UMWAIT allows for monitoring a range of addresses in a lightweight power/performance state or an enhanced mode that can still help with conserving power but less so in order to offer lower latencies. UMWAIT is intended to be used as an alternative to kernel spinloops when needing to wait/sleep for short periods of time when the system is idle.

Deprecating a.out Binaries

Filed under
Linux
Hardware

Remember a.out binaries? They were the file format of the Linux kernel till around 1995 when ELF took over. ELF is better. It allows you to load shared libraries anywhere in memory, while a.out binaries need you to register shared library locations. That's fine at small scales, but it gets to be more and more of a headache as you have more and more shared libraries to deal with. But a.out is still supported in the Linux source tree, 25 years after ELF became the standard default format.

Recently, Borislav Petkov recommended deprecating it in the source tree, with the idea of removing it if it turned out there were no remaining users. He posted a patch to implement the deprecation. Alan Cox also remarked that "in the unlikely event that someone actually has an a.out binary they can't live with, they can also just write an a.out loader as an ELF program entirely in userspace."

  • Intel Drops 2 Exciting Clues About The Future Of Clear Linux OS For 'Normal' Desktop Users [Ed: Intel is still trying, more desperately over time, to generate interest in its flailing GNU/Linux distro while putting back doors in every chip and doing other profoundly dubious things]

    I'm not a developer, a server administrator or anyone with advanced programming skills. I'm just a normal desktop Linux user who appreciates speed, stability, great aesthetics and ease of use. As such I've been keeping a close eye on Intel's Clear Linux, and have been insisting it's worth paying attention to. Intel's recent community efforts around Clear Linux -- and even certain touches they've implemented to the installer -- have given me the strong belief that the company is looking to serve people just like me in the near future. So I asked the burning question directly, and Intel just answered it.

  • Touch panel PCs offer a choice of 64 models mixing different sizes and Intel chips

    Taicenn’s Linux-friendly, IP65 protected “TPC-DCM” industrial panel PCs let you choose between 6th or 7th Gen U-series Core, Apollo Lake, or Bay Trail CPUs with 2x GbE, SATA, optional wireless, and capacitive touchscreens between 15 and 24 inches.

    Taicenn, which last year introduced an Intel Bay Trail based, in-vehicle TPC-DCXXXC1E panel PC has now returned with an industrial series of TPC-DCM panel PCs. You can choose between 64 configurations, with 8x Intel processor choices and 8x screen sizes: 15.0, 2x 15.6, 17.0, 18.5, 19.0, 21.5 and 24.0-inch models ranging from 1024 x 768 to 1920 x 1080 pixels.

  • More AMD Navi GPUs show up in a Linux driver

    A since-deleted commit for a Linux driver update hints at 4 new AMD Navi GPUs.

  • Libdrm Picks Up Support For AMD Navi

    As another one of the prerequisites for landing the AMD Radeon RX 5000 series "Navi" support in Mesa, the libdrm bits have just been merged.

    Libdrm is the Mesa DRM library that is needed for sitting between the Linux kernel Direct Rendering Manager (DRM) interfaces and the user-space components (depending upon the driver, as is required by like RadeonSI). Libdrm also ends up being used by the DDX drivers like xf86-video-amdgpu and other components as well depending upon the driver. As of a short time ago, the Navi bits landed in libdrm Git.

    The Navi support here isn't all that exciting and mostly boilerplate code for a new generation for a new family ID, a new member for a tile steering override for GFX10, GDDR6 as a new video memory type, and the largest addition is simply the new tests for VCN 2.0 video decode support.
