Using l5.1.1_2.0.0_6qp-ga binaries in a kk4.4.3_2.0.0-ga

Hi i.MX Community,

 

with our software we're experiencing random system freezes (due to GPU lockup) in kk4.4.3_2.0.0-ga that happen generally after 1 to 3 days of continuous run on a Boundary Devices Nitrogen6X.

The source of the problem seems to be in hwcomposer: removing all /system/lib/hw/hwc* libraries fixes the problem, but reduces graphical performance too.

 

We've tried using hwcomposer_fsl.imx6.so and hwcomposer_viv.imx6.so from l5.0.0_1.0.0-ga, but same problem holds.

We've tried also using hwcomposer_fsl.imx6.so and hwcomposer_viv.imx6.so from l5.1.1_2.0.0_6qp-ga and that fixes the lockup problem and brings also the performance we desire.

 

Problem is that the l5.1.1_2.0.0_6qp-ga is a i.MX6 Quad Plus only release. Even if we acknowledge hwcomposer_fsl.imx6.so and hwcomposer_viv.imx6.so from l5.1.1_2.0.0_6qp-ga are not meant to be used with i.MX6Q, are we allowed to use those files inside a kk4.4.3_2.0.0-ga release from a license standpoint?

 

Thanks,

Diego
