[Qemu-devel] [PATCH 1/1] Add support for PCI Enhanced Allocation "BARs"

2015-05-11 Thread Sean O. Stalley
PCI Enhanced Allocation is a new method of allocating MMIO & IO resources for PCI devices & bridges. It can be used instead of the traditional PCI method of using BARs. EA entries are hardware-initialized to a fixed address. Unlike BARs, regions described by EA are cannot be moved. Because of this
