questions about imx6d temperature trip point

processor:imx6D

 

We modfied the linux-imx/drivers/thermal/imx_thermal.c and chang change the passive and critical trip ponits because the video output will get wrong when the tempture reaching passive point.Is it safe enough to increase passive temperature to105 degree?

-#define IMX_TEMP_PASSIVE        85000
-#define IMX_TEMP_PASSIVE_COOL_DELTA    10000
+#define IMX_TEMP_PASSIVE        105000
+#define IMX_TEMP_CRITICAL        110000
+#define IMX_TEMP_PASSIVE_COOL_DELTA    2000

 

Besides,accroding to the "i.MX_Linux_Reference_Manual.pdf", cooling device will lower CPU frequency and notify GPU to run at a lower frequency when reaching passive point.So how can I prevent GPU to run at a lower frequency except changing the trip points?

 

Best regards
