Vivante GPU driver and 4GB DDR

Hi all,

 

The Vivante GPU driver fails to initialize on a system with 4GB DDR. It prints a "AXI BUS ERROR" line in the kernel messages and then prints a number of various register/memory dumps.

 

The driver works normally on the same system if DDR size is limited to 3GB with the "mem=3072MiB" kernel parameter.

 

It is a known issue? Is there a fix/workaround?

 

Regards,

Dmitry
