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
v1 of the patch series can be found at [1]
v2 of the patch series can be found at [2]
v3 of the patch series can be found at [3]
v4 of the patch series can be found at [4]
v5 of the patch series can be found at [5]
v6 of the patch series can be found at [6]
v7 of the patch series can be found at [7]
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 v7:
1) Added conditional operator to consicely write code to configure BAR
(Added a new patch to first simplify configuring BAR for physical
function)
2) Return error if virtual function number is > 1 for configuring config
space header
Changes from v6:
*) Rebased to 5.14-rc4
Changes from v5:
*) Rebased to 5.13-rc1
Changes from v4:
*) Added a fix in Cadence driver which was overwriting BAR configuration
of physical function.
*) Didn't include Tom's Acked-by since Cadence driver is modified in
this revision.
Changes from v3:
*) Fixed Rob's comment and added his Reviewed-by as suggested by him.
Changes from v2:
*) Fixed DT binding documentation comment by Rob
*) Fixed the error check in pci-epc-core.c
Changes from v1:
*) Re-based and Re-worked to latest kernel 5.10.0-rc2+ (now has generic
binding for EP)
