Danit Goldberg says: Packet based credit mode Packet based credit mode is an alternative end-to-end credit mode for QPs set during their creation. Credits are transported from the responder to the requester to optimize the use of its receive resources. In packet-based credit mode, credits are issued on a per packet basis. The advantage of this feature comes while sending large RDMA messages through switches that are short in memory. The first commit exposes QP creation flag and the HCA capability. The second commit adds support for a new DV QP creation flag. The last commit report packet based credit mode capability via the MLX5DV device capabilities. * branch 'mlx5-packet-credit-fc': IB/mlx5: Report packet based credit mode device capability IB/mlx5: Add packet based credit mode support net/mlx5: Expose packet based credit mode Signed-off-by: -

The device can support two credit modes, message based (default) and packet based. In order to enable packet based mode, the QP should be created with special flag that indicates this. This patch adds support for the new DV QP creation flag that can be used for RC QPs in order to change the credit mode. Signed-off-by:

Commit 4e045572 ("IB/hfi1: Add unique txwait_lock for txreq events") laid the ground work to support per resource waiting locking. This patch adds that with a lock unique to each sdma engine and pio sendcontext and makes necessary changes for verbs, PSM, and vnic to use the new locks. This is particularly beneficial for smaller messages that will exhaust resources at a faster rate. Fixes: 77241056 ("IB/hfi1: add driver files") Reviewed-by:

The call to sdma_progress() is called outside the wait lock. In this case, there is a race condition where sdma_progress() can return false and the sdma_engine can idle. If that happens, there will be no more sdma interrupts to cause the wakeup and the vnic_sdma xmit will hang. Fix by moving the lock to enclose the sdma_progress() call. Also, delete the tx_retry. The need for this was removed by: commit bcad2913 ("IB/hfi1: Serve the most starved iowait entry first") Fixes: 64551ede ("IB/hfi1: VNIC SDMA support") Reviewed-by:

This patch adds an interface to allow the driver to initialize the QP priv struct when the QP is created and after the qpn has been assigned. A field is added to the QP priv struct to reference the rcd and two new files are added to contain the function to initialize the rcd field so that more TID RDMA related code can be added here later.

Currently, When a reserved operation is completed, its entry in the send queue will not be unreserved, which leads to the miscalculation of qp->s_avail and thus the triggering of a WARN_ON call trace.

A CA is supposed to ignore FECN bits in multicast, ACK, and CNP packets. This patch corrects the behavior of the HFI1 driver in this regard by ignoring FECNs in those packet types. While fixing the above behavior, fix the extraction of the FECN and BECN bits from the packet headers for both 9B and 16B packets. Furthermore, this patch corrects the driver's response to a FECN in RDMA READ RESPONSE packets. Instead of sending an "empty" ACK, the driver now sends a CNP packet. While editing that code path, add the missing trace for CNP packets.

When it is requested to change its physical state back to Offline while in the process to go up, DC8051 will set the ERROR field in the DC8051_DBG_ERR_INFO_SET_BY_8051 register. This ERROR field will remain until the next time when DC8051 transitions from Offline to Polling. Subsequently, when the host requests DC8051 to change its physical state to Polling again, it may receive a DC8051 interrupt with the stale ERROR field still in DC8051_DBG_ERR_INFO_SET_BY_8051. If the host link state has been changed to Polling, this stale ERROR will force the host to transition to Offline state, resulting in a vicious cycle of Polling ->Offline->Polling->Offline. On the other hand, if the host link state is still Offline when the stale ERROR is received, the stale ERROR will be ignored, and the link will come up correctly. This patch implements the correct behavior by changing host link state to Polling only after DC8051 changes its physical state to Polling. Reviewed-by:

From Yishai, ----------------------------------- This series enriches DEVX support in few aspects: it enables interoperability between DEVX and verbs and improves mechanism for controlling privileged DEVX commands. The first patch updates mlx5 ifc file. Next 3 patches enable modifying and querying verbs objects via the DEVX interface. To achieve that the core layer introduced the 'UVERBS_IDR_ANY_OBJECT' type to match any IDR object. Once it's used by some driver's method, the infrastructure skips checking for the IDR type and it becomes the driver handler responsibility. The DEVX methods of modify and query were changed to get any object type via the 'UVERBS_IDR_ANY_OBJECT' mechanism. The type checking is done per object as part of the driver code. The next 3 patches introduce more robust mechanism for controlling privileged DEVX commands. The responsibility to block/allow per command was moved to be done in the firmware based on the UID credentials that the driver reports upon user context creation. This enables more granularity per command based on the device security model and the user credentials. In addition, by introducing a valid range for 'general commands' we prevent the need to touch the driver's code any time that a new future command will be added. The last patch fixes the XRC verbs flow once a DEVX context is used. This is needed as XRCD is some shared kernel resource and as such a kernel UID (=0) should be used in its related resources. Thanks Yishai Hadas ----------------------------------- The top 6 patches are the mlx5-devx series, the remainder are from the mlx5-next tree as the mlx5-devx series depended on the mlx5-next mlx5_ifc file update. * mlx5-devx: (42 commits) IB/mlx5: Allow XRC usage via verbs in DEVX context IB/mlx5: Update the supported DEVX commands IB/mlx5: Enforce DEVX privilege by firmware IB/mlx5: Enable modify and query verbs objects via DEVX IB/core: Enable getting an object type from a given uobject IB/core: Introduce UVERBS_IDR_ANY_OBJECT net/mlx5: Update mlx5_ifc with DEVX UCTX capabilities bits RDMA/mlx5: Unfold modify RMP function RDMA/mlx5: Unfold create RMP function RDMA/mlx5: Initialize SRQ tables on mlx5_ib RDMA/mlx5: Update SRQ functions signatures to mlx5_ib format RDMA/mlx5: Use stages for callback to setup and release DEVX RDMA/mlx5: Remove SRQ signature global flag net/mlx5: Move SRQ functions to RDMA part net/mlx5: Remove references to local mlx5_core functions net/mlx5: Remove not-used lib/eq.h header file net/mlx5: Remove dead transobj code net/mlx5: Align SRQ licenses and copyright information net/mlx5: Debug print for forwarded async events net/mlx5: Forward SRQ resource events ...

Allows XRC usage from the verbs flow in a DEVX context. As XRCD is some shared kernel resource between processes it should be created with UID=0 to point on that. As a result once XRC QP/SRQ are created they must be used as well with UID=0 so that firmware will allow the XRCD usage. Signed-off-by:
