Hi Fellow
I am currently working on bringing Xen(latest mainline 4.6 RC) alive on an ARM Cortex-A53 platform with 512 MB RAM.
Xen is complaining about it couldn't allocate 128 MB from DOM0 and stopped.
I tried to use pagealloc_info() to dump memory status, finding there's only small amount of memory in HEAP.
Does any one know what is going on or where to check for this problem??
Really appreciate for your help.
Thanks.
Tom
