我在树莓PI里面看到(http://www.raspberrypi.org/phpBB3/viewtopic.php?f=62&t=22288&start=25)这样一段:
And there is some truth to that.
What I am talking about is things like RISCOS and plan9 and others. It is easier to find ports for SoC's that have v7 instructions. Some of those vendors have not fully brought the GPU drivers up in those releases. Example; there are excelerated drivers for Ubuntu and the Panda. But I am not sure any of the other distributions have them. The ones that are available can probably be used on other Debian based releases. They probably do not work in the Android release for it.
That is the sticking point for ARM based boards. The CPU's are pretty much standard type to type, but the GPU are all different and need development to work. The OS may work just fine but the GPU drivers may be pretty plain.
I am sure that if the Foundation decides to build future models they will use a newer ARM version, if nothing else to make the OS development a whole lot easier on them. That will still leave the GPU development in their hands and Broadcoms possibly. With the production figures reaching a million I hope the Foundation will have even more help from Broadcom if they develop a new project!
我就想问,这个cubie是不是就像他说的这种情况呢?我的GPU从硬件上看起来主频很高,其实真正的使用性能并不高。
