Hi all, Today's linux-next merge of the rdma tree got a conflict in: drivers/infiniband/sw/rxe/rxe.c between commit: 8ce2eb9dfac8 ("RDMA/rxe: Fix the failure of ibv_query_device() and ibv_query_device_ex() tests") from the rdma-fixes tree and commit: d34d0bdb500e ("RDMA/rxe: Replace netdev dev addr with raw_gid") from the rdma tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc drivers/infiniband/sw/rxe/rxe.c index e27478fe9456,4e56a371deb5..000000000000 --- a/drivers/infiniband/sw/rxe/rxe.c +++ b/drivers/infiniband/sw/rxe/rxe.c @@@ -72,10 -71,45 +69,39 @@@ static void rxe_init_device_param(struc rxe->attr.max_pkeys = RXE_MAX_PKEYS; rxe->attr.local_ca_ack_delay = RXE_LOCAL_CA_ACK_DELAY; - ndev = rxe_ib_device_get_netdev(&rxe->ib_dev); - if (!ndev) - return; - + if (ndev->addr_len) { + memcpy(rxe->raw_gid, ndev->dev_addr, + min_t(unsigned int, ndev->addr_len, ETH_ALEN)); + } else { + /* + * This device does not have a HW address, but + * connection mangagement requires a unique gid. + */ + eth_random_addr(rxe->raw_gid); + } + addrconf_addr_eui48((unsigned char *)&rxe->attr.sys_image_guid, - ndev->dev_addr); + rxe->raw_gid); - dev_put(ndev); - rxe->max_ucontext = RXE_MAX_UCONTEXT; + + if (IS_ENABLED(CONFIG_INFINIBAND_ON_DEMAND_PAGING)) { + rxe->attr.kernel_cap_flags |= IBK_ON_DEMAND_PAGING; + + /* IB_ODP_SUPPORT_IMPLICIT is not supported right now. */ + rxe->attr.odp_caps.general_caps |= IB_ODP_SUPPORT; + + rxe->attr.odp_caps.per_transport_caps.ud_odp_caps |= IB_ODP_SUPPORT_SEND; + rxe->attr.odp_caps.per_transport_caps.ud_odp_caps |= IB_ODP_SUPPORT_RECV; + rxe->attr.odp_caps.per_transport_caps.ud_odp_caps |= IB_ODP_SUPPORT_SRQ_RECV; + + rxe->attr.odp_caps.per_transport_caps.rc_odp_caps |= IB_ODP_SUPPORT_SEND; + rxe->attr.odp_caps.per_transport_caps.rc_odp_caps |= IB_ODP_SUPPORT_RECV; + rxe->attr.odp_caps.per_transport_caps.rc_odp_caps |= IB_ODP_SUPPORT_WRITE; + rxe->attr.odp_caps.per_transport_caps.rc_odp_caps |= IB_ODP_SUPPORT_READ; + rxe->attr.odp_caps.per_transport_caps.rc_odp_caps |= IB_ODP_SUPPORT_ATOMIC; + rxe->attr.odp_caps.per_transport_caps.rc_odp_caps |= IB_ODP_SUPPORT_SRQ_RECV; + } } /* initialize port attributes */ @@@ -107,13 -141,18 +133,13 @@@ static void rxe_init_port_param(struct /* initialize port state, note IB convention that HCA ports are always * numbered from 1 */ -static void rxe_init_ports(struct rxe_dev *rxe) +static void rxe_init_ports(struct rxe_dev *rxe, struct net_device *ndev) { struct rxe_port *port = &rxe->port; - struct net_device *ndev; rxe_init_port_param(port); - ndev = rxe_ib_device_get_netdev(&rxe->ib_dev); - if (!ndev) - return; addrconf_addr_eui48((unsigned char *)&port->port_guid, - ndev->dev_addr); + rxe->raw_gid); - dev_put(ndev); spin_lock_init(&port->port_lock); }
