Now I have a question, we based on imx6q board orders a copy of their focus on application needs cutting system, the current application for rapid 3 d rendering demand is very strong, the current at the time of rendering processor always resource usage is very high, I divided the CMA is 320 m, then I put gc_hal_kernel_platform_imx6q14. Config file EXTRA_CFLAGS +=- DgcdFSL_CONTIGUOUS_SIZE=134217728 (128 m) is modified to EXTRA_CFLAGS +=- DgcdFSL_CONTIGUOUS_SIZE=268435456 (256 m), now the application of occupancy resources have decreased significantly, do excuse me I have a risk? Our memory 1 g, BSP is 3.14.52, give some advice!

The original poster hello! , I now use imx6q drawings when CPU utilization rate is very high, how to increase the GPU memory? How to set the CMA need?CodePudding user response:
Sorry failed to reply, my friend, you can directly modify the kernel. The config file CONFIG_CMA_SIZE_MBYTES=400, we can explore wx privately: AZWBL060310
