Dom0 memory restricted #39

Closed dsheets closed 7 years ago

dsheets commented 10 years ago

It would be nice not to have dom0 limited to 512M of memory when nothing else is happening on the device.

https://github.com/mirage/xen-arm-builder/blob/master/boot/boot-cubieboard2.cmd#L15 would appear to be the right place but any value >512M results in:

This is a known issue in Xen 4.4 and fixed in dev

Even setting the max to 1G and then writing to /sys/devices/system/xen_memory/xen_memory0/target_kb doesn't work past 512M. I guess I'll have to wait for 4.5.

As the recent refresh uses the Alpine Xen package which is 4.6 I believe, I'll close this for now. If it still occurs, please do reopen...
