In the News The Raspberry Pi has inspired a flock of competitors. Among them are the A13-OLinuXino, which you can purchase here for 45 euros. It comes with an A13 Cortex A8 processor at 1GHz, 3D Mali400 GPU, 512 MB RAM, and complete set of ports. Video is VGA. It ships Android 4.0 but also runs various Linux distros. You might also check out the $49US Cubieboard here and the UG802 for $89US here. And there's the MK802 micro-PC, a USB-sized device priced at $74US that runs Android 4.0, Ubuntu, Debian, and other distros. The tiny single-board computer has come of age.

That depends on your POV, the driver is just an 'RPC shim' to a companion CPU which runs the "real" driver, so
-from a maintenance POV this is useless
-from a licensing POV 100% of the code running on the ARM CPU is Free which is a big news indeed.

Let me see if I get this right...
-GPU firmware is closed-source
-Driver is open-source, the communication protocol with the firmware is open-specced, and it is possible to implement an OSS OpenGL stack

Is that the way it works? If so, isn't it a big win already for OSS drivers developers?

If I got this right, the opensource driver is just a way to access a high level API which is then compiled by the firmware running on the companion CPU(VPU) to primitives which are then run on the GPU.
So if there is a bug on the firmware, it's difficult to workaround because you don't have access to the low-level primitives.
