Working together with DeepComputing on the Framework 13 (RISCV-64, Spacemit K3 / ROMA III), we’ve been working on bringing up a fully open-source Linux stack.

Good news: we now have the open-source Mesa3D Imagination PowerVR driver running — including Vulkan and Zink for GLES This is a pretty big milestone for the historically under-supported PowerVR (tile-based deferred rendering) GPUs.

Kernel-side was straightforward. Mesa userspace took significantly more effort — lots of debugging and trial-and-error.

Stil WIP:

• GPU frequency scaling
• general stability/perf tuning

More updates soon.

While we are at it, and MetaComputing sent their Framework 13 ARM64 module over, too: finally testing the state of ARM Mali w/ latest Mesa3d Panfrost with T2/Linux, too! Spoilter: it mostly works and performance is currently orders of magnitude better than the PowerVR driver. The only main bug I could spot are some black flashing redrawing artifacts: https://www.youtube.com/watch?v=3dZ4bp-dQSU
