There is a third option and it really is what this "ubuntu" bug is meant to track: Enable Imagination/PVR support for Mesa version 25.x in Ubuntu 25.10.
I can see we have the source code already: https://salsa.debian.org/xorg-team/lib/mesa/-/tree/ubuntu/src/imagination So it might just be a matter of "turning it on". I think that's the only real way forward here but it would require an Ubuntu engineer to set up a riscv64 machine to try it out and make the changes for Ubuntu 25.10... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2105985 Title: Issue with enabling harware acceleration support on Ubuntu 24[RISCV64] Status in linux package in Ubuntu: Incomplete Status in linux-riscv package in Ubuntu: Incomplete Status in mesa package in Ubuntu: Incomplete Bug description: We are currently working on enabling GNOME (Wayland) to run on top of a Imagination GPU hardware accelerator for RISCV64. Initially, we tested this on Ubuntu 22.04 LTS, but after receiving suggestions from the GNOME forum, we decided to switch to Ubuntu 24.04 LTS. Since upgrading, we’ve noticed significant improvements, and GNOME is running more smoothly than expected. However, the graphics configuration still shows “Software Rendering” instead of utilising hardware acceleration. Despite configuring the Imagination GPU, we are unable to enable hardware acceleration for GNOME, which is impacting 3D rendering performance. Please find the below EGL logs details for Imagination GPU as below: OpenGL ES profile vendor: Imagination Technologies OpenGL ES profile renderer: PowerVR Rogue GE8300 OpenGL ES profile version: OpenGL ES 3.2 OpenGL ES profile shading language version: OpenGL ES GLSL ES 3.20 OpenGL ES profile extensions: After several attempts and experiments running GPU computing tests, such as OpenCL tests on the Imagination GPU, an issue arises when attempting to execute 3D programs[opengles], as they are being executed on the CPU instead of the imagination GPU.
