KGSL is just kernel graphics support layer.  It's the in-kernel Adreno drivers that communicate with the userland binaries to render graphics.

If you've ported an application from desktop I assume you're using glMapBufferRange or glBufferSubData. Don't use either of those since they are broken as shit on Adreno drivers.
