PVR is a GPU. A80 uses a different model of PVR GPU. That means that the work done by Intel might be usable to some extent. However, the PVR closed drivers provided so far are unstable leading to system crashes. It is unknown if the issue is in software or if the hardware is so buggy that a stable driver is not feasible. > > Regarding the older SoCs in the A series, it is important to have a view > whether there will be effort to support the VPU on Linux. > I have the impression that it would greatly benefit boards like the Banana Pi, > the OLinuXinos, the Cubieboards, etc. There is some effort to make opensource Mali GPU drivers by the Lima project. There is no usable code, however. On Allwinner hardware this is hindered by lack of KMS driver but Exynos which uses same GPU core has something that looks like KMS driver by now.
