H A D | spapr.h | c8545818 Thu May 07 00:33:30 CDT 2015 Alexey Kardashevskiy <aik@ozlabs.ru> spapr_pci: Introduce a liobn number generating macros We are going to have multiple DMA windows per PHB and we want them to migrate so we need a predictable way of assigning LIOBNs. This introduces a macro which makes up a LIOBN from fixed prefix, PHB index (unique PHB id) and window number. This introduces a SPAPR_PCI_DMA_WINDOW_NUM() to know the window number from LIOBN. It is used to distinguish the default 32bit windows from dynamic windows and avoid picking default DMA window properties from a wrong TCE table.
