Hi community,

 

Our patner have a question about i.MX6SL GPU.
You know i.MX6SL GPU is able to be disabled by power gating by REG1_TARG in PMU_REG_CORE register of IMX6SLRM Rev.1.
Then, if OpenVG or OpenGL ES API is issued even tough GPU is power gated, what is happen?
GPU returns error? System stops since unexecutable API? or CPU emulate OpenVG/OpenGL ES API?


Best Regards,
Satoshi Shimoda
