i.MX8MM Etnaviv Bus Error mit 4GB RAM

[Frieder Schrempf]

Hi,

I'm seeing the following messages on a system with i.MX8MM with 4GB of 
RAM. When I limit the RAM to 3GB (mem=3G) it doesn't happen anymore.

   etnaviv-gpu 38000000.gpu: AXI bus error
   etnaviv-gpu 38000000.gpu: MMU fault status 0x00000000
   etnaviv-gpu 38000000.gpu: recover hung GPU!

Is this something that needs to be fixed on Etnaviv-level or on 
SoC-level? And how could a solution look like?

Thanks
Frieder
