- Thread-topic: [PATCH v1 0/6] Implement SR-IOV support for PVH
This series enables support for PCI SR-IOV capabilty for PVH domains.
It allows Dom0 to enable and use SR-IOV virtual functions and for this
functions to be passed to guests.
To achieve this, handlers for SRIOV_CONTROL register and simplified handlers
for VFs header were implemented.
Core functionality is based on previous works [1] and [2].
Xen relies on dom0 to enable SR-IOV and call PHYSDEVOP_pci_device_* to inform
about addition/removal of VFs.
Tested on R-Car Spider board with Samsung NVMe SSD Controller 980 and Intel
X550T ethernet card.
Mykyta Poturai (1):
vpci: rename and export vpci_bar_add_rangeset
Stewart Hildebrand (5):
vpci: rename and export vpci_modify_bars
vpci: rename and export vpci_guest_mem_bar_{read,write}
vpci: add SR-IOV support for PVH Dom0
vpci: export vpci_init_capability_list()
vpci: add SR-IOV support for DomUs
