kind of like a printer that accepts postscript. sounds ok to me.
(maybe different if the GPU can read and write to system RAM (can it).)

The GPU on that chip is in full control of the system. The ARM core can only do what the GPU lets it, not the other way around as people are probably used to.

Not if they are behind an IOMMU, like on most of the recent x86 platforms. Right?
Airlie: raspberry pi drivers are NOT useful Posted Oct 26, 2012 17:14 UTC (Fri) by khim (subscriber, #9252) [Link] Right, but IDE and Ethernet drivers were in Linux 20 years ago, IOMMU is relatively recent creation. If the GPU development will shift to something like Broadcom is pushing I'm pretty sure interface with GPU will receive something like IOMMU in 20 years time.
