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.

When using CM to establish connections, qp number that was freed just now will be rejected by ib core. To fix these problem, We change qpn allocation to round-robin mode. We added the round-robin mode for allocating resources using bitmap. We use round-robin mode for qp number and non round-robing mode for other resources like cq number, pd number etc. Signed-off-by:

This patch modified the condition of notifying hardware loopback. In hip06, RoCE Engine has several ports, one QP is related to one port. hardware only support loopback in the same port, not in the different ports. So, If QP related to port N, the dmac in the QP context equals the smac of the local port N or the loop_idc is 1, we should set loopback bit in QP context to notify hardware. Signed-off-by:

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.

Currently when calling mlx5_add_flow_rule we accept only one flow destination, this commit allows to pass multiple destinations. This change forces us to change the return structure to a more flexible one. We introduce a flow handle (struct mlx5_flow_handle), it holds internally the number for rules created and holds an array where each cell points the to a flow rule. From the consumers (of mlx5_add_flow_rule) point of view this change is only cosmetic and requires only to change the type of the returned value they store. From the core point of view, we now need to use a loop when allocating and deleting rules (e.g given to us a flow handler). Signed-off-by:

When adding a new rule, if we can match it with compare_match_value and flow tag we might be able to insert the rule to the same fte. In order to do that, there must be an overlap between the actions of the fte and the new rule. When updating the action of an existing fte, we must tell the firmware we are doing so. Signed-off-by:

TSAR (stands for Transmit Scheduling ARbiter) is a hardware component that is responsible for selecting the next entity to serve on the transmit path. The arbitration defines the QoS policy between the agents connected to the TSAR. The TSAR is a consist two main features: 1) BW Allocation between agents: The TSAR implements a defecit weighted round robin between the agents. Each agent attached to the TSAR is assigned with a weight and it is awarded transmission tokens according to this weight. 2) Rate limer per agent: Each agent attached to the TSAR is (optionally) assigned with a rate limit. TSAR will not allow scheduling for an agent exceeding its defined rate limit. In this patch we implement the API of manipulating the TSAR. Signed-off-by:

The recent changes, which forced the registration of the boot cpu on UP systems, which do not have ACPI tables, have been fixed for systems w/o local APIC, but left a wreckage for systems which have neither ACPI nor mptables, but the CPU has an APIC, e.g. virtualbox. The boot process crashes in prefill_possible_map() as it wants to register the boot cpu, which needs to access the local apic, but the local APIC is not yet mapped. There is no reason why init_apic_mapping() can't be invoked before prefill_possible_map(). So instead of playing another silly early mapping game, as the ACPI/mptables code does, we just move init_apic_mapping() before the call to prefill_possible_map(). In hindsight, I should have noticed that combination earlier. Sorry for the churn (also in stable)!
