IMX6QP：MAJOR video memory exhausted!

[zhuchaozhu]

Hi ， my friend

   I have video memory problems, and the console prints the warning message as follows:

   *** Warning: MAJOR video memory exhausted! to use normal memory ***
    ------------ Video memory usage ------------
   cat /proc/gpu_viv/video_memory' to see details
    ------------------- END --------------------
   uid=0 gid=1007@nutshell:/ # cat /proc/gpu_viv/video_memory
   VIDEO MEMORY:
   gcvPOOL_SYSTEM:
   free= 696280
   used= 32858152
   peakValue= 32860312
   total= 33554432
   gcvPOOL_CONTIGUOUS:
   Used : 80628656 B
   gcvPOOL_VIRTUAL:
   Used : 0 B
   N ON PAGED MEMORY:
   Used : 0 B

   I do not know why video memory has been exhausted, maybe I changed some configuration.

   Does anyone have encountered this error in imx6qp and I want someone to give me some help to solve this problem

   Thanks

Hello,

  You may try to vary kernel "cma" parameter.

  Please refer to Chapter 9 (GPU Memory Introduction) of “i.MX_Graphics_User's_Guide.pdf”

regarding GPU memory usage.
