I’m a newer user of Xen on ARM working with the Xilinx MPSOC platform.   We want to restrict Xens available memory and the Xen command line seems to be easy answer.


We see the command line show mem=1G from “xl info”, but the total_memory does not reflect what we set mem= to.


Does this still work on ARM with device tree and we’re doing something wrong?
