As such, it is useless to pass device arguments to the plug callback. Those arguments are available within the devargs field of the rte_device structure. Fixes: 7c8810f43f6e ("bus: introduce device plug/unplug") Fixes: 00e62aae69c0 ("bus/pci: implement plug/unplug operations") Fixes: a3ee360f4440 ("eal: add hotplug add/remove device") Signed-off-by: Gaetan Rivet --- lib/librte_eal/common/eal_common_dev.c | 2 +- lib/librte_eal/common/eal_common_pci.c | 2 +- lib/librte_eal/common/eal_common_vdev.c | 2 +- lib/librte_eal/common/include/rte_bus.h | 6 +----- 4 files changed, 4 insertions(+), 8 deletions(-) diff --git a/lib/librte_eal/common/eal_common_dev.c b/lib/librte_eal/common/eal_common_dev.c index f5566a6..6fcbea4 100644 --- a/lib/librte_eal/common/eal_common_dev.c +++ b/lib/librte_eal/common/eal_common_dev.c @@ -188,7 +188,7 @@ int rte_eal_hotplug_add(const char *busname, const char *devname, goto err_devarg; } - ret = bus->plug(dev, devargs); + ret = bus->plug(dev); if (ret) { RTE_LOG(ERR, EAL, "Driver cannot attach the device (%s)\n", dev->name); diff --git a/lib/librte_eal/common/eal_common_pci.c b/lib/librte_eal/common/eal_common_pci.c index cdd197a..9ad1bf1 100644 --- a/lib/librte_eal/common/eal_common_pci.c +++ b/lib/librte_eal/common/eal_common_pci.c @@ -541,7 +541,7 @@ pci_find_device(const struct rte_device *start, rte_dev_cmp_t cmp, } static int -pci_plug(struct rte_device *dev, const char *devargs __rte_unused) +pci_plug(struct rte_device *dev) { return pci_probe_all_drivers(RTE_DEV_TO_PCI(dev)); } diff --git a/lib/librte_eal/common/eal_common_vdev.c b/lib/librte_eal/common/eal_common_vdev.c index 79bb795..0817573 100644 --- a/lib/librte_eal/common/eal_common_vdev.c +++ b/lib/librte_eal/common/eal_common_vdev.c @@ -316,7 +316,7 @@ vdev_find_device(const struct rte_device *start, rte_dev_cmp_t cmp, } static int -vdev_plug(struct rte_device *dev, const char *args __rte_unused) +vdev_plug(struct rte_device *dev) { return vdev_probe_all_drivers(RTE_DEV_TO_VDEV(dev)); } diff --git a/lib/librte_eal/common/include/rte_bus.h b/lib/librte_eal/common/include/rte_bus.h index af9f0e1..c79368d 100644 --- a/lib/librte_eal/common/include/rte_bus.h +++ b/lib/librte_eal/common/include/rte_bus.h @@ -113,15 +113,11 @@ typedef struct rte_device * * @param dev * Device pointer that was returned by a previous call to find_device. * - * @param devargs - * Device declaration. - * * @return * 0 on success. * !0 on error. */ -typedef int (*rte_bus_plug_t)(struct rte_device *dev, - const char *devargs); +typedef int (*rte_bus_plug_t)(struct rte_device *dev); /** * Implementation specific remove function which is responsible for unlinking -- 2.1.4
