[Qemu-devel] [RFC PATCH v2 08/13] spapr_pci: Enable DDW

2014-08-15 Thread Alexey Kardashevskiy
This implements DDW for emulated PHB. This advertises DDW in device tree. Since QEMU does not implement any 64bit DMA capable device, this hack has been used to enable 64bit DMA on E1000: diff --git a/hw/net/e1000.c b/hw/net/e1000.c index 0fc29a0..131f80a 100644 --- a/hw/net/e1000.c +++ b/hw/net
