linux版本的GPU驱动是需要rockchip提供的。arm社区上的驱动都是公版的,但各家厂商稍有不同。
关于linux版 ...

就是正在进行,还没有完成的意思喽,暂时还不能使用。
That's right, the new Mali-T76x drivers built for GNU/Linux ARMv7 fbdev only (no windowing system at the moment) are now available as well as several other r5p0 drivers on the public download page:
http://malideveloper.arm.com/dev ... user-space-drivers/
In order to use this, you will also need to build the kernel-side driver and replace the kernel in your build. This can be achieved by following the Firefly wiki page I mentioned earlier and starting with this Linux repository (master branch):
T-Firefly / Firefly-RK3288-kernel / Commits — Bitbucket
https://bitbucket.org/T-Firefly/firefly-rk3288-kernel.git
It has an early r4p1 kernel-side Mali GPU driver, which is not compatible with the new r5p0 user-side driver. So you need to upgrade the kernel-side Mali driver with the source code archive from this page:
http://malideveloper.arm.com/dev ... nel-device-drivers/
You'll need to remove the main drivers files under drivers/gpu/arm/, but not drivers/gpu/arm/midgard/platform/rk which contains the RK3288 platform support files, and replace them with the files from the archive. Some relatively small changes may be needed in the RK3288 platform files to make it work with the new r5p0 driver; sorry we haven't got a patch for that at the moment.
