Hi Marek,
I guess you are using old kernel config with 5.x kernel, and the kernel
config option CONFIG_HMM is missing because the dependency option
CONFIG_ZONE_DEVICE is missing in old config file. Please update your
kernel config file to enable option CONFIG_ZONE_DEVICE.
You should have this message in dmesg log:
"HMM_MIRROR kernel config option is not enabled, "
"add CONFIG_ZONE_DEVICE=y in config file to fix
