Those\nnode are created and filled based on PCI core information but the\nfwnode device field is not set.\n\nWhen later an overlay is applied, this confuses fw_devlink. Indeed,\nwithout any device attached to the node, fw_devlink considers that this\nnode will never become a device. When this node is pointed as a\nsupplier, devlink looks at its ancestors in order to find a node with a\ndevice that could be used as the supplier.\n\nIn the PCI use case, this leads to links that wrongly use the PCI root\nbridge device as the supplier instead of the expected PCI device.\n\nSetting the fwnode device to the device of the PCI device allows devlink\nto use this device as a supplier and so, correct links are created.\n\nSigned-off-by: Herve Codina <herve.codina@bootlin.com>\n---\n drivers/pci/of.c | 7 +++++++\n 1 file changed, 7 insertions(+)", "diff": "diff --git a/drivers/pci/of.c b/drivers/pci/of.c\nindex 5fb7f501fd35..b694fcda16b1 100644\n--- a/drivers/pci/of.c\n+++ b/drivers/pci/of.c\n@@ -709,6 +709,13 @@ void of_pci_make_dev_node(struct pci_dev *pdev)\n \tif (ret)\n \t\tgoto out_free_node;\n \n+\t/*\n+\t * Set the fwnode device in order to have fw_devlink creating links\n+\t * pointing to this PCI device instead of walking up to the PCI host\n+\t * bridge.\n+\t */\n+\tfw_devlink_set_device(&np->fwnode, &pdev->dev);\n+\n \tret = of_changeset_apply(cset);\n \tif (ret)\n \t\tgoto out_free_node;\n", "prefixes": [ "v6", "12/27" ] }
