7dac7abe - common/mlx5: check send on time capability

Thu, 24 Feb 2022 10:54:59 +0000

common/mlx5: check send on time capabilityThe patch provides check for send scheduling on time hardware capability.With this capability enabled hardware is able to handle Wait WQEswith directly specified timestamp values. No Clock Queue is neededanymore to handle send scheduling.Signed-off-by: Viacheslav Ovsiienko List of files: /dpdk/drivers/common/mlx5/mlx5_devx_cmds.h

38eb5c9f - net/mlx5: fix E-Switch manager vport ID

Tue, 22 Feb 2022 15:07:16 +0000

net/mlx5: fix E-Switch manager vport IDOne of the E-Switch vports plays the special role - it is assigned as"E-Switch manager" and has some special exclusive rights and duties - itmaintains all the representors, manages FDB domain flows, etc. Bydefault, the E-Switch vport index was supposed to be zero on standaloneNICs (regular ConnectX) and 0xFFFE SmartNIC (BlueField), but that wasnot always correct - this index can be assigned with any value bykernel/hypervisor.Currently the E-Switch manager vport id is supposed to be default - 0for standalone NICs, and 0xFFFE for the SmartNICs, and is deduced fromthe device PCI id.To handle this and do not suggest any default values, can use DevX APIto query E-Switch manager vport ID directly from the firmware duringinitialization, and use that value by default. If the new method is notprovided (legacy firmware), fallback to use the PCI id approach.Fixes: a564038699f9 ("net/mlx5: support E-Switch manager egress traffic match")Cc: stable@dpdk.orgSigned-off-by: Shun Hao Acked-by: Viacheslav Ovsiienko List of files: /dpdk/drivers/common/mlx5/mlx5_devx_cmds.h

10599cf8 - common/mlx5: add minimum WQE size for striding RQ

Tue, 23 Nov 2021 18:38:03 +0000

common/mlx5: add minimum WQE size for striding RQSome devices have a WQE size limit for striding RQ. On some newerdevices, this limitation is smaller and information on its size isprovided by the firmware.This patch adds the attribute query from firmware: the minimum requiredsize of WQE buffer for striding RQ in granularity of Bytes.Cc: stable@dpdk.orgSigned-off-by: Michael Baum Acked-by: Matan Azrad List of files: /dpdk/drivers/common/mlx5/mlx5_devx_cmds.h

ba707cdb - crypto/mlx5: fix queue size configuration

Mon, 08 Nov 2021 13:09:20 +0000

crypto/mlx5: fix queue size configurationThe DevX interface for QP creation expects the number of WQEBBs.Wrongly, the number of descriptors was provided to the QP creation.In addition, the QP size must be a power of 2 what was not guaranteed.Provide the number of WQEBBs to the QP creation API.Round up the SQ size to a power of 2.Rename (sq/rq)_size to num_of_(send/receive)_wqes.Fixes: 6152534e211e ("crypto/mlx5: support queue pairs operations")Cc: stable@dpdk.orgSigned-off-by: Raja Zidane Acked-by: Matan Azrad Acked-by: Tal Shnaiderman List of files: /dpdk/drivers/common/mlx5/mlx5_devx_cmds.h

febcac7b - net/mlx5: support Rx queue delay drop

Fri, 05 Nov 2021 15:30:38 +0000

net/mlx5: support Rx queue delay dropFor the Ethernet RQs, if there all receiving descriptors areexhausted, the packets being received will be dropped. This behaviorprevents slow or malicious software entities at the host fromaffecting the network. While for hairpin cases, even if there is nosoftware involved during the packet forwarding from Rx to Tx side,some hiccup in the hardware or back pressure from Tx side may stillcause the descriptors to be exhausted. In certain scenarios it may bepreferred to configure the device to avoid such packet drops,assuming the posting of descriptors will resume shortly.To support this, a new devarg "delay_drop" is introduced. By default,the delay drop is enabled for hairpin Rx queues and disabled forstandard Rx queues. This value is used as a bit mask: - bit 0: enablement of standard Rx queue - bit 1: enablement of hairpin Rx queueAnd this attribute will be applied to all Rx queues of a device.The "rq_delay_drop" capability in the HCA_CAP is checked beforecreating any queue. If the hardware capabilities do not supportthis delay drop, all the Rx queues will still be created withoutthis attribute, and the devarg setting will be ignored even if itis specified explicitly. A warning log is used to notify theapplication when this occurs.Signed-off-by: Bing Zhao Acked-by: Viacheslav Ovsiienko List of files: /dpdk/drivers/common/mlx5/mlx5_devx_cmds.h

ee160711 - common/mlx5: support basic receive memory pool

Thu, 04 Nov 2021 12:33:09 +0000

common/mlx5: support basic receive memory poolThe hardware Receive Memory Pool (RMP) object holds the destination forincoming packets/messages that are routed to the RMP through RQs. RMPenables sharing of memory across multiple Receive Queues. MultipleReceive Queues can be attached to the same RMP and consume memoryfrom that shared poll. When using RMPs, completions are reported to theCQ pointed to by the RQ, and this Completion Queue can be shared aswell.This patch adds DevX supports of PRM RMP object.Signed-off-by: Xueming Li Acked-by: Viacheslav Ovsiienko List of files: /dpdk/drivers/common/mlx5/mlx5_devx_cmds.h
