--- Comment #4 from Philip Yang philip.yang@amd.com --- I will change the error message for this specific case to mention the missing kernel config option.
I cannot add select ZONE_DEVICE in driver Kconfig file because there will be a circular dependency issue. The old or wired kernel config file may select to don't enable HMM or ZONE_DEVICE.
Thanks, Philip
