2019-02-20 Thread Eric Auger
This series aims to bump the 255GB RAM limit in machvirt and to support device memory in general, and especially PCDIMM/NVDIMM. In machvirt versions < 4.0, the initial RAM starts at 1GB and can grow up to 255GB. From 256GB onwards we find IO regions such as the additional GICv3 RDIST region, high
