I have compiled the Mali kernel module for Android and tried to boot Android based on Scott's proposed change.I am able to load the mali kernel module but I am getting an error while surfaceflinger tries load the GLES libs and use the same. The logcat and dmesg output is here:

Did some changes to pick the right gralloc lib and the ion library. It still fails. Here is the logcat:

Gralloc tries to request fb with triplebuffering configuration but current FB is configured for single buffer (looks like):

Please open this file: drivers/gpu/drm/hisilicon/hisi_drm_fb.h and change bellow macro value to 3 then we can get triplebuffer. Please have a try. Thanks.

Thanks ! I don't see the FB related error not but I still get the ION errors:

Is there source available for gralloc and libion ? Can someone in Hisilicon LT help with this ?

I've been going around with Jorge for a couple of days with this.  He

Vishal and he sees this error with make 3.81, and tells me Fathi sees
this error in local builds.

Works for me with GNU Make 3.81 on Ubuntu 12.04.  I didn't remove
anything from Kbuild in the patch I sent you as I didn't hit this issue,
but the bit of logic involved only tends to make sense when the driver
is built out-of-tree.  So in this context I think it can be simplified
as Scott suggested (i.e. by removing the license test) as we know it's
all GPL.

on my side it builds fine (I havent been able to reproduce the error using the
following)
