ib_query_gid() fetches the GID from the software cache maintained in ib_core for RoCE ports. Therefore, simplify the provider drivers for RoCE to treat query_gid() callback as never called for RoCE, and only require non-RoCE devices to implement it. Signed-off-by:

Extending uverbs_ioctl header with driver_id and another reserved field. driver_id should be used in order to identify the driver. Since every driver could have its own parsing tree, this is necessary for strace support. Downstream patches take off the EXPERIMENTAL flag from the ioctl() IB support and thus we add some reserved fields for future usage. Reviewed-by:

The hip06 and hip08 run on a little endian ARM, it needs to revise the annotations to indicate that the HW uses little endian data in the various DMA buffers, and flow the necessary swaps throughout. The imm_data use big endian mode. The cpu_to_le32/le32_to_cpu swaps are no-op for this, which makes the only substantive change the handling of imm_data which is now mandatory swapped. This also keep match with the userspace hns driver and resolve the warning by sparse. Signed-off-by:

Considering the compatibility of supporting hip08's eq process and possible changes of data structure, this patch refactors the eq code structure of hip06. We move all the eq process code for hip06 from hns_roce_eq.c into hns_roce_hw_v1.c, and also for hns_roce_eq.h. With these changes, it will be convenient to add the eq support for later hardware version. Signed-off-by:

When lp_qp_work is NULL, we should return ENOMEM. In order to do so, we had to make some upper layer functions return a value instead of being void type so we can propagate the error up the stack.

In order to support the scalability of the hardware version, the features irrelevant to the hardware will be located in the hns-roce.ko, and the hardware relevant operations will be located in hns_roce_hw_v1.ko or hns_roce_hw_v2.ko based on the series chips. The hip08 RoCE engine is a PCI device, hip06 RoCE engine is a platform device. In order to support both platform device and PCI device, We replace &hr_dev->pdev->dev with hr_dev->dev in hns-roce.ko as belows: Before modification: struct device *dev = hr_dev->dev; After modification: struct device *dev = &hr_dev->pdev->dev; The related structure: struct hns_roce_dev { ... struct platform_device *pdev; struct pci_dev *pci_dev; struct device *dev; ... } Signed-off-by: -

The hardware relevant definitions and operations are implemented in hns_roce_hw_v* file. According to the diversity chips, the file is named as hns_roce_hw_v1.c or hns_roce_hw_v2.c etc. The general software process flow, common structures and allocated algorithms are implemented in other files located in hns roce driver. In order to support the scalability of the hardware version, the common driver features are in the hns-roce.ko, and the hardware relevant operations are in hns_roce_hw_v1.ko or hns_roce_hw_v2.ko based on the series chips.

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. This patch doesn't add any new functionality. Signed-off-by:

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. Signed-off-by:

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.

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.
