The PCIe EP device must be powered-on and configured before the PCIe HOST device. Once the above step is completed, the PCIe endpoint is ready to establish a link with the host (RC). # echo 1 > controllers/fe000000.pcie-ep/start # On CIP SLTS Linux v4.19 # echo 1 > controllers/fe000000.pcie_ep/start # On upstream kernel In order for the EP device to be ready to establish the link, the following command should be given. # ln -s functions/pci_epf_test/func1/ controllers/fe000000.pcie-ep/ # On CIP SLTS Linux v4.19 # ln -s functions/pci_epf_test/func1/ controllers/fe000000.pcie_ep/ # On upstream kernel

Use the configfs to bind the function device to one of the controller driver present in the system. In order for the endpoint function device to be useful, it has to be bound to a PCIe endpoint controller driver. On G2x platforms max value should be 16.īinding pci-epf-test device to a EP controller Note: If the root device isn't capable of handling the vectors then the endpoint device (/dev/pci-endpoint-test.0) wont be created on the host. # echo 1 > functions/pci_epf_test/func1/msi_interrupts Set the MSI interrupts supported, msi vectors supported are 1/2/4/8/16/32, so the value to echo should be one of them. # echo 0x002d > functions/pci_epf_test/func1/deviceid # For RZ/G2E # echo 0x002b > functions/pci_epf_test/func1/deviceid # For RZ/G2N # echo 0x0028 > functions/pci_epf_test/func1/deviceid # For RZ/G2M # echo 0x0025 > functions/pci_epf_test/func1/deviceid # For RZ/G2H

# echo 0x1912 > functions/pci_epf_test/func1/vendorid In order to change the vendorid and device-id, the following command can be used. The user can configure the pci-epf-test device using the configfs. The pci-epf-test driver populates vendorid with 0xffff and interrupt_pin with 0x0001 The driver populates these entries with default values when the device is bound to the driver. The PCIe endpoint framework populates the directory with configurable fields.Ĭache_line_size interrupt_pin subclass_code The “mkdir functions/pci_epf_test/func1” above creates the pci-epf-test function device. # mount -t configfs none /sys/kernel/config To create pci-epf-test device, the following commands can be used PCIe endpoint function device can be created using configfs. The pci-epf-test function driver can be used to test the endpoint functionality of the PCIe controller. The tests that are currently supported
