[Xen-devel] [v8][PATCH 09/17] hvmloader/ram: check if guest memory is out of reserved device memory maps

2014-12-01 Thread Tiejun Chen
We need to check to reserve all reserved device memory maps in e820 to avoid any potential guest memory conflict. Currently, if we can't insert RDM entries directly, we may need to handle several ranges as follows: a. Fixed Ranges --> BUG() lowmem_reserved_base-0xA: reserved by BIOS implement
