Currently, when cma_resolve_ib_dev() searches for a matching GID it will stop searching after encountering the first empty GID table entry. This behavior is wrong since neither IB nor RoCE spec enforce tightly packed GID tables. For example, when the matching valid GID entry exists at index N, and if a GID entry is empty at index N-1, cma_resolve_ib_dev() will fail to find the matching valid entry.

2021-12-14RDMA/hns: Support direct wqe of userspaceYixing Liu5-12/+92
The current write wqe mechanism is to write to DDR first, and then notify the hardware through doorbell to read the data. Direct wqe is a mechanism to fill wqe directly into the hardware. 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.

2021-12-14RDMA/hns: Fix RNR retransmission issue for HIP08Yangyang Li2-7/+65
Due to the discrete nature of the HIP08 timer unit, a requester might finish the timeout period sooner, in elapsed real time, than its responder does, even when both sides share the identical RNR timeout length included in the RNR Nak packet and the responder indeed starts the timing prior to the requester. Furthermore, if a 'providential' resend packet arrived before the responder's timeout period expired, the responder is certainly entitled to drop the packet silently in the light of IB protocol. To address this problem, our team made good use of certain hardware facts: 1) The timing resolution regards the transmission arrangements is 1 microsecond, e.g. if cq_period field is set to 3, it would be interpreted as 3 microsecond by hardware 2) A QPC field shall inform the hardware how many timing unit (ticks) constitutes a full microsecond, which, by default, is 1000 3) It takes 14ns for the processor to handle a packet in the buffer, so the RNR timeout length of 10ns would ensure our processing mechanism is disabled during the entire timeout period and the packet won't be dropped silently To achieve (3), we permanently set the QPC field mentioned in (2) to zero which nominally indicates every time tick is equivalent to a microsecond in wall-clock time; now, a RNR timeout period at face value of 10 would only last 10 ticks, which is 10ns in wall-clock time. It's worth noting that we adapt the driver by magnifying certain configuration parameters(cq_period, eq_period and ack_timeout)by 1000 given the user assumes the configuring timing unit to be microseconds. Also, this particular improvisation is only deployed on HIP08 since other hardware has already solved this issue.

2021-12-14drm/amd/display: Add debugfs entry for ILRWayne Lin1-0/+134
[Why & How] In order to know the intermediate link rates supported by the eDP panel and test to select the optimized link rate to save power, create a new debugfs entry "ilr_setting" for setting ILR.

2021-12-14drm/amd/display: Set exit_optimized_pwr_state for DCN31Nicholas Kazlauskas1-0/+1
[Why] SMU now respects the PHY refclk disable request from driver. This causes a hang during hotplug when PHY refclk was disabled because it's not being re-enabled and the transmitter control starts on dc_link_detect. [How] We normally would re-enable the clk with exit_optimized_pwr_state but this is only set on DCN21 and DCN301. Set it for dcn31 as well. This fixes DMCUB timeouts in the PHY.

2021-12-14mmc: core: Remove redundant driver match functionlizhe1-11/+0
If there is no driver match function, the driver core assumes that each candidate pair (driver, device) matches, see driver_match_device(). Drop the mmc bus's match function that always returned 1 and so implements the same behaviour as when there is no match function.
