Big news for #risc_v SBCs with imagination #gpu support!

@pine64 #star64

nice that the img-bxe-4-32-mc4 (included in the StarFive JH7110 (used by #pine64 #star64 ( https://wiki.pine64.org/wiki/STAR64 ))) is capable of splitting the GPU in up to 8 virtual GPUs. Sadly the SiFive U74 CPU core does not implement the RISC-V H extension (extension for hardware virtualization instructions).

After some shenanigans with common ground, the testing rig works, nothing burns and it even boots. Only Debian so far but I will get there. #pine64 #star64 #riscv64

I just pushed some big updates to my #PinetabV and #Star64 plasma images. If you are already running and want to upgrade please see the release notes here: https://github.com/Fishwaldo/meta-pine64/releases/tag/v2.1 #pine64 #RISCV

Another Week - Another new image for #pinetabv (and #star64) - Kernel Version Bumps, Package Bumps in this release. Also, last actual release for PtV for a while, as now the images can be upgraded via "apt upgrade" online.
Major Changes for PtV include sound (enable it in settings), a updated kernel version 5.15.127 with the latest Starfive Vendor patches, improved EMMC performance, and a few thousand additional packages available via apt!

Grab it from https://github.com/Fishwaldo/meta-pine64/releases/tag/v2.0

Currently building new images for the #pinetabv and #star64. This is going to take a while, so I thought I’d take the dog for a walk, only to find him passed out like this!

@xue35 follow https://github.com/NixOS/nixpkgs/issues/101651 for #nixos #riscv progress.

some people had it running, but many packages are not compatible yet and i think there is no official binary cache, so you have to build everything yourself or use a community binary cache

here is for example hardware specific config for a #StarFive #VisionFive 2 SBC: https://github.com/NixOS/nixos-hardware/tree/master/starfive/visionfive/v2

or a #Pine64 #Star64: https://github.com/NixOS/nixos-hardware/tree/master/pine64/star64
