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] v8 of the patch series can be found at [8] 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 v8: 1) Include pci-epf.h in pcie-cadence.h and use BAR_4 instead of 4 2) Get reg for configuring BAR using if..else.. for physical function and virtual function instead of over-writing reg for virtual function. 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) [1] -> http://lore.kernel.org/r/20191231113534.30405-1-kishon@ti.com [2] -> http://lore.kernel.org/r/20201112175358.2653-1-kishon@ti.com [3] -> https://lore.kernel.org/r/20210305050410.9201-1-kishon@ti.com [4] -> http://lore.kernel.org/r/20210310160943.7606-1-kishon@ti.com [5] -> https://lore.kernel.org/r/20210419083401.31628-1-kishon@ti.com [6] -> http://lore.kernel.org/r/20210517074723.10212-1-kishon@ti.com [7] -> https://lore.kernel.org/r/20210803050310.27122-1-kishon@ti.com [8] -> https://lore.kernel.org/r/20210811064656.15399-1-kishon@ti.com Kishon Vijay Abraham I (8): dt-bindings: PCI: pci-ep: Add binding to specify virtual function PCI: endpoint: Add support to add virtual function in endpoint core PCI: endpoint: Add support to link a physical function to a virtual function PCI: endpoint: Add virtual function number in pci_epc ops PCI: cadence: Simplify code to get register base address for configuring BAR PCI: cadence: Add support to configure virtual functions misc: pci_endpoint_test: Populate sriov_configure ops to configure SR-IOV device Documentation: PCI: endpoint/pci-endpoint-cfs: Guide to use SR-IOV .../PCI/endpoint/pci-endpoint-cfs.rst | 12 +- .../devicetree/bindings/pci/pci-ep.yaml | 7 + drivers/misc/pci_endpoint_test.c | 1 + .../pci/controller/cadence/pcie-cadence-ep.c | 196 +++++++++++++----- drivers/pci/controller/cadence/pcie-cadence.h | 12 ++ .../pci/controller/dwc/pcie-designware-ep.c | 36 ++-- drivers/pci/controller/pcie-rcar-ep.c | 19 +- drivers/pci/controller/pcie-rockchip-ep.c | 18 +- drivers/pci/endpoint/functions/pci-epf-ntb.c | 89 ++++---- drivers/pci/endpoint/functions/pci-epf-test.c | 74 ++++--- drivers/pci/endpoint/pci-ep-cfs.c | 24 +++ drivers/pci/endpoint/pci-epc-core.c | 134 ++++++++---- drivers/pci/endpoint/pci-epf-core.c | 146 ++++++++++++- include/linux/pci-epc.h | 57 ++--- include/linux/pci-epf.h | 16 +- 15 files changed, 616 insertions(+), 225 deletions(-)
