I am trying to disable power management in Linux for Zynq Ultrascale devices. Looking at the kernel, it is enabled by default. When I set CONFIG_PM=n and build the kernel, it doesn't take effect. Also I wish to know if there is any dependency on other mdoules like CONFIG_SUSPEND ?
I tried disabling both of the above parameters by setting CONFIG_PM=n and CONFIG_SUSPEND=n in my kernel.cfg. But it throws out a big blob of error which is very difficult for me as a entry level embedded linux engineer to understand. Can someone shine some light on this.
Edit:
Based on the suggestion from @sawdust. I tried to do the kernel changes using menuconfig. Then the petalinux-build breaks. I am a newbie and it is a bit difficult to understand from the log, why it breaks.
Will be great to have some experienced eyes look over the build log and suggest why it fails.
