2022-05-24RDMA/hfi1: Remove all traces of diagpkt supportDennis Dalessandro1-23/+0
One of the concessions we made to get our driver upstream was to remove the diagnostic packet support. There is however still some cruft that was left over. Remove it.

2022-05-24RDMA/hfi1: Consolidate software versionsDennis Dalessandro1-17/+0
There is no need to have separate user and kernel software versions. There is a single software that the kernel is compatible with. Also remove the notion of a "kernel type" that is long since deprecated.

2022-05-24RDMA/hfi1: Remove pointless driver versionDennis Dalessandro1-15/+0
Driver versions have long been forbidden in the RDMA subsystem. We removed most of the code relating to them and have been very strict about not allowing. However there is some leftover versioning that we do not need. Get rid of that.

2020-05-21IB/hfi1: Enable the transmit side of the datagram ipoib netdevPiotr Stankiewicz1-0/+1
This patch hooks the transmit side of the datagram netdev with ipoib by setting the rdma_netdev_get_params function for the hfi1 ib_device_ops structue. It also enables the receiving side by adding the AIP capability into the default capabilities.

2020-05-21IB/hfi1: Remove module parameter for KDETH qpnsGary Leshner1-7/+0
The module parameter for KDETH qpns is being removed in favor of always using the default value of 0x80 as the qpn prefix. Defines have been added for various KDETH values including the prefix of 0x80. The reserved range now starts at the base value for KDETH qpns (0x80) and extends up to and including the last qpn for other reserved QP prefixed types. Adjust other QP prefixed define names to match KDETH defined names.

2019-02-05IB/hfi1: TID RDMA flow allocationKaike Wan1-0/+4
The hfi1 hardware flow is a hardware flow-control mechanism for a KDETH data packet that is received on a hfi1 port. It validates the packet by checking both the generation and sequence. Each QP that uses the TID RDMA mechanism will allocate a hardware flow from its receiving context for any incoming KDETH data packets. This patch implements: (1) a function to allocate hardware flow (2) a function to free hardware flow (3) a function to initialize hardware flow generation for a receiving context (4) a wait mechanism if the hardware flow is not available (4) a function to remove the qp from the wait queue for hardware flow when the qp is reset or destroyed.

2017-10-18IB/hfi1: Eliminate allocation while atomicDon Hiatt1-0/+1
The PIO trailing buffer was being dynamically allocated but the kcalloc return value was not being checked. Further, the GFP_KERNEL was being used even though the send engine might be called with interrupts disabled. Since the maximum size of the trailing buffer is only 12 bytes (CRC = 4, LT = 1, Pad = 0 to 7 bytes) just statically allocate the buffer, remove the alloc entirely and share it with the SDMA engine by making it global.
