2021-10-04qed: Remove e4_ and _e4 from FW HSIShai Malin1-1/+1
The existing qed/qede/qedr/qedi/qedf code uses chip-specific naming in structures, functions, variables and defines in FW HSI (Hardware Software Interface). The new FW version introduced a generic naming convention in HSI in-which the same code will be used across different versions for simpler maintainability. It also eases in providing support for new features. With this patch every "_e4" or "e4_" prefix or suffix is not needed anymore and it will be removed.

2021-03-26RDMA: Support more than 255 rdma portsMark Bloch1-4/+4
Current code uses many different types when dealing with a port of a RDMA device: u8, unsigned int and u32. Switch to u32 to clean up the logic. This allows us to make (at least) the core view consistent and use the same type. Unfortunately not all places can be converted. Many uverbs functions expect port to be u8 so keep those places in order not to break UAPIs. HW/Spec defined values must also not be changed. With the switch to u32 we now can support devices with more than 255 ports. U32_MAX is reserved to make control logic a bit easier to deal with. As a device with U32_MAX ports probably isn't going to happen any time soon this seems like a non issue. When a device with more than 255 ports is created uverbs will report the RDMA device as having 255 ports as this is the max currently supported. The verbs interface is not changed yet because the IBTA spec limits the port size in too many places to be u8 and all applications that relies in verbs won't be able to cope with this change. At this stage, we are extending the interfaces that are using vendor channel solely Once the limitation is lifted mlx5 in switchdev mode will be able to have thousands of SFs created by the device. As the only instance of an RDMA device that reports more than 255 ports will be a representor device and it exposes itself as a RAW Ethernet only device CM/MAD/IPoIB and other ULPs aren't effected by this change and their sysfs/interfaces that are exposes to userspace can remain unchanged. While here cleanup some alignment issues and remove unneeded sanity checks (mainly in rdmavt), Link: https://lore.kernel.org/r/20210301070420.439400-1-leon@kernel.org Signed-off-by: Mark Bloch <mbloch@nvidia.com> Signed-off-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

2020-10-26RDMA: Remove uverbs cmds from drivers that don't use themJason Gunthorpe1-7/+0
Allowing userspace to invoke these commands is probably going to crash these drivers as they are not tested and not expecting to use them on a user object. For example pvrdma touches cq->ring_state which is not initialized for user QPs. These commands are effected: - IB_USER_VERBS_CMD_REQ_NOTIFY_CQ is ibv_cmd_req_notify_cq() in rdma-core, only hfi1, ipath and rxe calls it. - IB_USER_VERBS_CMD_POLL_CQ is ibv_cmd_poll_cq() in rdma-core, only ipath and hfi1 calls it. - IB_USER_VERBS_CMD_POST_SEND/RECV is ibv_cmd_post_send/recv() in rdma-core, only ipath and hfi1 call them. - IB_USER_VERBS_CMD_POST_SRQ_RECV is ibv_cmd_post_srq_recv() in rdma-core, only ipath and hfi1 calls it. - IB_USER_VERBS_CMD_PEEK_CQ isn't even implemented anywhere - IB_USER_VERBS_CMD_CREATE/DESTROY_AH is ibv_cmd_create/destroy_ah() in rdma-core, only bnxt_re, efa, hfi1, ipath, mlx5, orcrdma, and rxe call it.

2020-10-26RDMA: Move more uverbs_cmd_mask settings to the coreJason Gunthorpe1-7/+1
These functions all depend on the driver providing a specific op: - REREG_MR is rereg_user_mr(). bnxt_re set this without providing the op - ATTACH/DEATCH_MCAST is attach_mcast()/detach_mcast(). usnic set this without providing the op - OPEN_QP doesn't involve the driver but requires a XRCD. qedr provides xrcd but forgot to set it, usnic doesn't provide XRCD but set it anyhow. - OPEN/CLOSE_XRCD are the ops alloc_xrcd()/dealloc_xrcd() - CREATE_SRQ/DESTROY_SRQ are the ops create_srq()/destroy_srq() - QUERY/MODIFY_SRQ is op query_srq()/modify_srq(). hns sets this but sometimes supplies a NULL op. - RESIZE_CQ is op resize_cq(). bnxt_re sets this boes doesn't supply an op - ALLOC/DEALLOC_MW is alloc_mw()/dealloc_mw(). cxgb4 provided an (now deleted) implementation but no userspace All drivers were checked that no drivers provide the op without also setting uverbs_cmd_mask so this should have no functional change.

2020-10-16RDMA: Explicitly pass in the dma_device to ib_register_deviceJason Gunthorpe1-1/+2
The code in setup_dma_device has become rather convoluted, move all of this to the drivers. Drives now pass in a DMA capable struct device which will be used to setup DMA, or drivers must fully configure the ibdev for DMA and pass in NULL. Other than setting the masks in rvt all drivers were doing this already anyhow. mthca, mlx4 and mlx5 were already setting up maximum DMA segment size for DMA based on their hardweare limits in: __mthca_init_one() dma_set_max_seg_size (1G) __mlx4_init_one() dma_set_max_seg_size (1G) mlx5_pci_init() set_dma_caps() dma_set_max_seg_size (2G) Other non software drivers (except usnic) were extended to UINT_MAX [1, 2] instead of 2G as was before.

2019-05-26qed*: Add iWARP 100g supportMichal Kalderon1-0/+13
Add iWARP engine affinity setting for supporting iWARP over 100g. iWARP cannot be distinguished by the LLH from L2, hence the engine division will affect L2 as well. For this reason we add a parameter to devlink to determine the engine division.

Additionally, store the init_port function pointer in ib_device_ops, so that it can be accessed in subsequent patches when binding rdma device to net namespace.
