RDMA/hns: Support userspace configuring congestion control algorithm with QP granularity Currently, congestion control algorithm is statically configured in FW, and all QPs use the same algorithm(except UD which has a fixed configuration of DCQCN). This is not flexible enough. Support userspace configuring congestion control algorithm with QP granularity while creating QPs. If the algorithm is not specified in userspace, use the default one.

RDMA/hns: Fix init failure of RoCE VF and HIP08 During device init, a struct for HW stats will be allocated. As HW stats are not supported for VF and HIP08, currently hns_roce_alloc_hw_port_stats() returns NULL in this case. However, ib-core considers the returned NULL pointer as memory allocation failure and returns ENOMEM, eventually leading to the failure of VF and HIP08 init. In the case where the driver does not support the .alloc_hw_port_stats() ops, ib-core will return EOPNOTSUPP and ignore this error code in the upper layer function. So for VF and HIP08, just don't set the HW stats ops to ib-core.

RDMA/hns: Fix incorrect sge nums calculation The user usually configures the number of sge through the max_send_sge parameter when creating qp, and configures the maximum size of inline data that can be sent through max_inline_data. Inline uses sge to fill data to send. Expect the following: 1) When the sge space cannot hold inline data, the sge space needs to be expanded to accommodate all inline data 2) When the sge space is enough to accommodate inline data, the upper limit of inline data can be increased so that users can send larger inline data Currently case one is not implemented. When the inline data is larger than the sge space, an error of insufficient sge space occurs. This part of the code needs to be reimplemented according to the expected rules. The calculation method of sge num is modified to take the maximum value of max_send_sge and the sge for max_inline_data to solve this problem.

In the case of light load, the wqe will be filled into pcie bar space of the hardware, this will reduce one memory access operation and therefore reduce the latency. SIMD instructions allows cpu to write the 512 bits at one time to device memory, thus it can be used for posting direct wqe. Add direct wqe enable switch and address mapping.

RDMA: Support more than 255 rdma ports 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>

This largely obsoletes the cmd_mask stuff, but there is some tricky bits in drivers preventing it from being removed. Remove the easy elements of uverbs_ex_cmd_mask by pre-setting them in the core code. These are triggered soley based on the related ops function pointer. query_device_ex is not triggered based on an op, but all drivers already implement something compatible with the extension, so enable it globally too.

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.

RDMA: Connect between the mmap entry and the umap_priv structure The rdma_user_mmap_io interface created a common interface for drivers to correctly map hw resources and zap them once the ucontext is destroyed enabling the drivers to safely free the hw resources. However, this meant the drivers need to delay freeing the resource to the ucontext destroy phase to ensure they were no longer mapped. The new mechanism for a common way of handling user/driver address mapping enabled notifying the driver if all umap_priv mappings were removed, and enabled freeing the hw resources when they are done with and not delay it until ucontext destroy. Since not all drivers use the mechanism, NULL can be sent to the rdma_user_mmap_io interface to continue working as before. Drivers that use the mmap_xa interface can pass the entry being mapped to the rdma_user_mmap_io function to be linked together.

For each mode, we use corresponding semaphores to protect the cmd queue resource competition, so called event_sem and poll_sem. During cmd init, both semaphores are initialized and poll mode is selected. Thus, there is no need to up poll_sema again in cmd_use_polling. Furthermore, there is no need to down the sema of the other side while switching mode. This patch aims to decouple the switch between event mode and poll mode of cmd.

Set them both up at the same time and make dev_name() the lead name, which is the proper use of the driver core APIs. To make it very clear that the name is not valid until registration pass it in to the ib_register_device() call rather than messing with ibdev->name directly. Also the reorganization now checks that dev_name is unique even if it does not contain a %.

IB/core: add max_send_sge and max_recv_sge attributes This patch replaces the ib_device_attr.max_sge with max_send_sge and max_recv_sge. It allows ulps to take advantage of devices that have very different send and recv sge depths. For example cxgb4 has a max_recv_sge of 4, yet a max_send_sge of 16. Splitting out these attributes allows much more efficient use of the SQ for cxgb4 with ulps that use the RDMA_RW API. Consider a large RDMA WRITE that has 16 scattergather entries. With max_sge of 4, the ulp would send 4 WRITE WRs, but with max_sge of 16, it can be done with 1 WRITE WR.

IB: Query ports via the core instead of direct into the driver Change the drivers to call ib_query_port in their get port immutable handler instead of their own query port handler. Doing this required to set the core cap flags of this device before the ib_query_port call is made, since the IB core might need these caps to serve the port query. Drivers are ensured by the IB core that the port attributes passed to the port query verb implementation are zero, and hence we removed the zeroing from the drivers.

IB/hns: Fix the bug when free mr If the resources of mr are freed while executing the user case, hardware can not been notified in hip06 SoC. Then hardware will hold on when it reads the payload by the PA which has been released. In order to slove this problem, RoCE driver creates 8 reserved loopback QPs to ensure zero wqe when free mr. When the mac address is reset, in order to avoid loopback failure, we need to release the reserved loopback QPs and recreate them.

IB/hns: Implement the add_gid/del_gid and optimize the GIDs management IB core has implemented the calculation of GIDs and the management of GID tables, and it is now responsible to supply query function for GIDs. So the calculation of GIDs and the management of GID tables in the RoCE driver is redundant. The patch is to implement the add_gid/del_gid to set the GIDs in the RoCE driver, remove the redundant calculation and management of GIDs in the notifier call of the net device and the inet, and update the query_gid.

IB/hns: Add code for refreshing CQ CI using TPTR This patch added the code for refreshing CQ CI using TPTR in hip06 SoC. We will send a doorbell to hardware for refreshing CQ CI when user succeed to poll a cqe. But it will be failed if the doorbell has been blocked. So hardware will read a special buffer called TPTR to get the lastest CI value when the cq is almost full. This patch support the special CI buffer as follows: a) Alloc the memory for TPTR in the hns_roce_tptr_init function and free it in hns_roce_tptr_free function, these two functions will be called in probe function and in the remove function. b) Add the code for computing offset(every cq need 2 bytes) and write the dma addr to every cq context to notice hardware in the function named hns_roce_v1_write_cqc. c) Add code for mapping TPTR buffer to user space in function named hns_roce_mmap. The mapping distinguish TPTR and UAR of user mode by vm_pgoff(0: UAR, 1: TPTR, others:invaild) in hip06. d) Alloc the code for refreshing CQ CI using TPTR in the function named hns_roce_v1_poll_cq. e) Add some variable definitions to the related structure.

IB/hns: Add & initialize "node_guid" parameter for RDMA CM According to the Infiniband spec, NodeGUID uniquely identifies a node. This must be initialized to some unique value. This patch adds the support to the HNS RoCE driver to fetch the NodeGUID value from DT or ACPI and then use this value to initialize the node_guid parameter of IB device. This value shall be used by RDMA CM.

IB/hns: Add support of ACPI to the Hisilicon RoCE driver This patch is meant to add support of ACPI to the Hisilicon RoCE driver. Changes done are primarily meant to detect the type and then either use DT specific or ACPI spcific functions. Where ever possible, this patch tries to make use of Unified Device Property Interface APIs to support both DT and ACPI through single interface. This patch depends upon HNS ethernet driver to Reset RoCE. This function within HNS ethernet driver has also been enhanced to support ACPI and is part of other accompanying patch with this patch-set.
