| |
Patch series *) Adds support to add virtual functions to enable endpoint controller which supports SR-IOV capability *) Add support in Cadence endpoint driver to configure virtual functions *) Enable pci_endpoint_test driver to create pci_device for virtual functions
Here both physical functions and virtual functions use the same pci_endpoint_test driver and existing pcitest utility can be used to test virtual functions as well.
Changes from v1: *) Re-based and Re-worked to latest kernel 5.10.0-rc2+ (now has generic binding for EP)
Patch series is created on top of NTB series [2]
v1 of the patch series can be found @ [1]
