Dear All,

Hello. My customer would like to change the user/kernel memory split from 2G/2G to 3G/1G in i.MX6DQ.

BSP: Linux L3.14.52

Default BSP setting is Kernel/User=2G/2G.

[Question]

Is it necessary to set Kernel/User=2G/2G?

(Do you have any reason?)

But, the content was unrelated with my question.

[Question]

Is there an influence over the hardware by this change user/kernel memory?

(i.e.May one change user/kernel memory by customer's responsibility?)
