It's still experimental, but working.

Another interesting thing is the official VC4 driver recently submitted to Linux Kernel 4.4

There are some improvements on VC4 build.

- try it if you are interested.

hey, awesome work, finally was able to compile the source today... Aida64 app shows the gl extensions although their is still the issue of CPU being stuck at 600mhz, and arm_freq=600 doesn't hep.

I would appreciate if you share your GPU enabled 5.1.1 build with me somewhere. I tried to build it myself (v 6.0) but looks like my HDD is dying and drops I/O errors.

hello and really thanks for your works.
Is there a link for a ready to try image with VC4 GPU based to download ?

I was able to build a kernel, but not to build the system.img and ramdisk.img:

are you sure that 32-bit stuff are installed?

I was missing several programs like Bison and Flex and some others...
