Radxa updates Rock Pi 4 with NVMe and debuts PoE HAT and a tiny RK3308-based voice board

Filed under

Radxa unveiled a 38 x 38mm, $10 and up “Rock Pi S” SBC that runs Linux on a quad -A53 RK3308. There’s also a v1.4 update of the RK3399-based Rock Pi 4 that adds 4MB SPI for booting NVMe drives plus a Rock Pi PoE HAT and a USB 3.0 eMMC adapter.

Radxa, which returned from a long development hiatus last fall with an impressively low-cost, $39 and up Rock Pi 4 SBC equipped with a Rockchip RK3399, has now returned with an updated v1.4 model with NVMe support. The email announcement from Radxa project leader Tom Cubie also previewed a tiny Rock Pi S board for voice applications, a Rock Pi PoE HAT for adding Power-over-Ethernet to the Rock Pi 4, and a USB 3.0 based eMMC reader.

Graphics: Intel, Weston, NVIDIA and AMD

  • Intel's IGC 1.0.4241 Graphics Compiler Adds DG1 Platform Support

    Significant with this new version of the IGC compiler is the DG1 platform is supported, their first graphics card. IGC already supported Gen12/Xe while now the initial bits are in place for the forthcoming DG1 discrete graphics card. For weeks now we've been seeing Intel's many open-source developers posting new DG1 enablement patches from the Linux kernel through their Mesa stack to the media encode/decode driver and now working its way into DG1 for their compute stack. Obviously you also need to be running on the future Linux 5.9 kernel and more for getting this DG1 support all aligned but at least the IGC side work is now in place.

  • Weston 9.0 release schedule
    Hi all,
    Here is the release schedule for Weston 9.0, the next major version:
    - Alpha: July 30th, in 4 weeks
    - Beta: August 13th
    - RC1: August 27th
    - First possible release: September 3rd
    Package maintainers are encouraged to pick up the pre-releases to make
    sure packaging can be tested (and fixed) before the stable release.
    Let me know if there's something in particular you want merged for 9.0.

  • Wayland's Weston 9.0 Aims For Release In Early September

    With Weston 8.0 having shipped in January, Wayland developers are beginning to prepare for the next feature release of this reference Wayland compositor. Simon Ser has once again stepped up to take over Weston release management duties. He is planning to tag the Weston 9.0 Alpha at the end of June, a Weston 9.0 Beta in mid-August, and a first release candidate at the end of April. If all goes well he hopes to ship Weston 9.0 on 3 September but could be delayed by some days if additional release candidates are warranted.

  • LLVMpipe Gallium3D Driver Now Exposes OpenGL 4.0

    The LLVMpipe Gallium3D driver that provides a software/CPU-based OpenGL implementation for running on systems as a fallback path when no GPU / hardware OpenGL driver is available, a vendor-neutral path for debug purposes, and similar use-cases, now has OpenGL 4.0 support.

  • NVIDIA Video Codec SDK 10 Brings Few Changes For This Proprietary Library

    NVIDIA has quietly released Video Codec SDK 10 as the newest version of their proprietary video encode/decode implementation designed for their GPUs. [...] NVIDIA has already contributed to FFMpeg support for using the new NVENC presets, multi-pass encode modes, and low-delay key frame scaling for this video library as part of the Video Codec SDK 10 support. A follow-up commit added additional H.264 levels now supported.

  • RadeonSI Switches To Make Greater Wave64 Use On Navi

    While RDNA/Navi brought Wave32 support, the open-source RadeonSI Gallium3D driver for Linux has decided to switch to make greater use now of Wave64 for more shaders. [...] The change to use Wave64 for more shader stages was merged this week for Mesa 20.2. The commit does add the new "nggctess" perf flag for always using NGG culling for tessellation, complementing the existing nggc (for always using NGG culling) and nonggc for disabling NGG culling.

  • Mike Blumenkrantz: Binding Locations

    So let’s get down to pixels. The UBO indexing is now fixed-ish, which means moving onto the next step: setting up bindings for the UBOs. A binding in this context is the numeric id assigned to a UBO for the purposes of accessing it from a shader, which also corresponds to the uniform block index. In mesa, this is the struct nir_variable::data.binding member of a UBO. A load_ubo instruction will take this value as its first parameter, which means there’s a need to ensure that everything matches up just right.

Review of the HP Pavilion 14-ce0830nd

Would I recommend the HP Pavilion 14-ce0830nd? To be honest, its a mixed bag on openSUSE. Installation of openSUSE Leap 15.2 was very easy. And installation of a dual boot system with Windows 10 was easy as well. The laptop has an attractive look and feel. The display, speakers, keyboard and external ports are all good. The touchpad is too sensitive. The machine has enough RAM, enough storage and the hard drives are performant. The Intel CPU/GPU is great. Which means that this is a great machine for multitasking. The gaming performance on the Intel GPU on openSUSE Leap 15.2 is good enough to play various open source games on medium/high settings. Read more
