Airlie: raspberry pi drivers are NOT useful

Airlie: raspberry pi drivers are NOT useful

Parent article: Airlie: raspberry pi drivers are NOT useful

I've been saying something similar since they released it.

The killer question to me is: What's the difference between this and the nVidia binary blob? Because, to me, the issue is the same - we have the source to some shim but how the driver actually does anything is in the blob and unchangeable.

And yet, the nVidia blob is considered the worst-of-the-worst when it comes to proprietariness, and this is being hailed as some wonderful example of open-source openness that's never been seen before.

The two are exactly the same in the sense that it's impossible for anybody besides the owner of that blob to debug and fix problems, or to extend it in ways that might be useful.

They are completely different in the sense that the nvidia approach puts the blob (or at least one of them) into kernel space, which is tied closely to a particular OS version, while the Broadcom approach means they have a well-defined interface between the two processors and the ARM host can run any OS and version you want and still use those interfaces by linking in their free shim layer.

For people playing with FreeBSD or Wayland on this particular machine, the release is great news because this is the missing piece they were waiting for. For someone who wants to make use of the GPU for something the blob didn't do (or didn't do right), it changes nothing.

At the very least they let us upgrade kernels without worrying about an 'old' module...

I would be VERY curious to see how the vendor reacts to bug reports. Why not run every test we have against this driver and submit (prioritized) bugs for each and every one we find.

If they fix nothing we understand the limitations of the firmware, we win with every fix provided.

Well another similarity to NVIDIA I expect, is that this Broadcom blob can also scribble over whatever memory it likes.

So should you trust kernel bug reports from RPi systems?

As I understand it, this blob is in the user space. It can only scribble over its own memory.

The user-space blob on the ARM side is what BCM have open-sorced. The remaining closed component is the GPU firmware which can indeed scribbl over anything it likes since the GPU is in many ways the main processor.

I think this is a step forward, but it's being claimed by the RPi folks as some sort of giant leap, and it's not. It's not entirely the substance that's upsetting people, it's the misleading billing.

The substance is bad, too. The RPi is losing the last bits of credibility it had.
