hyperv/pcib: enable PCIe pass-through (a.k.a. Discrete Device Assignment) 2016-11-16T09:25:00+00:00 Dexuan Cui dexuan@FreeBSD.org 2016-11-16T09:25:00+00:00 871c968b3ae6904d1ce7bd08388e5c4c1498fdc9 The feature enables us to pass through physical PCIe devices to FreeBSD VM running on Hyper-V (Windows Server 2016) to get near-native performance with low CPU utilization. The patch implements a PCI bridge driver to support the feature: 1) The pcib driver talks to the host to discover device(s) and presents the device(s) to FreeBSD's pci driver via PCI configuration space (note: to access the configuration space, we don't use the standard I/O port 0xCF8/CFC method; instead, we use an MMIO-based method supplied by Hyper-V, which is very similar to the 0xCF8/CFC method). 2) The pcib driver allocates resources for the device(s) and initialize the related BARs, when the device driver's attach method is invoked; 3) The pcib driver talks to the host to create MSI/MSI-X interrupt remapping between the guest and the host; 4) The pcib driver supports device hot add/remove.
