2024-03-15net/mlx5: Check capability for fw_resetMoshe Shemesh
[ Upstream commit 5e6107b499f3fc4748109e1d87fd9603b34f1e0d ] Functions which can't access MFRL (Management Firmware Reset Level) register, have no use of fw_reset structures or events. Remove fw_reset structures allocation and registration for fw reset events notifications for these functions. Having the devlink param enable_remote_dev_reset on functions that don't have this capability is misleading as these functions are not allowed to influence the reset flow. Hence, this patch removes this parameter for such functions. In addition, return not supported on devlink reload action fw_activate for these functions.

2023-12-04net/mlx5e: Tidy up IPsec NAT-T SA discoveryLeon Romanovsky
IPsec NAT-T packets are UDP encapsulated packets over ESP normal ones. In case they arrive to RX, the SPI and ESP are located in inner header, while the check was performed on outer header instead. That wrong check caused to the situation where received rekeying request was missed and caused to rekey timeout, which "compensated" this failure by completing rekeying.

2023-11-01vdpa/mlx5: Enable hw support for vq descriptor mappingDragos Tatulea
Vq descriptor mappings are supported in hardware by filling in an additional mkey which contains the descriptor mappings to the hw vq. A previous patch in this series added support for hw mkey (mr) creation for ASID 1. This patch fills in both the vq data and vq descriptor mkeys based on group ASID mapping. The feature is signaled to the vdpa core through the presence of the .get_vq_desc_group op.

2023-08-09net/mlx5: Expose NIC temperature via hardware monitoring kernel APIAdham Faris
Expose NIC temperature by implementing hwmon kernel API, which turns current thermal zone kernel API to redundant. For each one of the supported and exposed thermal diode sensors, expose the following attributes: 1) Input temperature. 2) Highest temperature. 3) Temperature label: Depends on the firmware capability, if firmware doesn't support sensors naming, the fallback naming convention would be: "sensorX", where X is the HW spec (MTMP register) sensor index. 4) Temperature critical max value: refers to the high threshold of Warning Event. Will be exposed as `tempY_crit` hwmon attribute (RO attribute). For example for ConnectX5 HCA's this temperature value will be 105 Celsius, 10 degrees lower than the HW shutdown temperature). 5) Temperature reset history: resets highest temperature. For example, for dualport ConnectX5 NIC with a single IC thermal diode sensor will have 2 hwmon directories (one for each PCI function) under "/sys/class/hwmon/hwmon[X,Y]".

2023-08-07net/mlx5: Allocate completion EQs dynamicallyMaher Sanalla
This commit enables the dynamic allocation of EQs at runtime, allowing for more flexibility in managing completion EQs and reducing the memory overhead of driver load. Whenever a CQ is created for a given vector index, the driver will lookup to see if there is an already mapped completion EQ for that vector, if so, utilize it. Otherwise, allocate a new EQ on demand and then utilize it for the CQ completion events. Add a protection lock to the EQ table to protect from concurrent EQ creation attempts. While at it, replace mlx5_vector2irqn()/mlx5_vector2eqn() with mlx5_comp_eqn_get() and mlx5_comp_irqn_get() which will allocate an EQ on demand if no EQ is found for the given vector.

Currently, once driver load completes, IRQ requests were performed for all vectors. However, as we move to support dynamic creation of EQs, this will not be the case as some IRQs will not exist at this stage. Thus, in such case, use the default CPU to IRQ mapping which is the serial mapping based on IRQ vector index. Meaning, the n'th vector gets mapped to the n'th CPU. Introduce an API function mlx5_comp_vector_cpu() that takes an IRQ index and provides the corresponding CPU mapping. It utilizes the existing IRQ affinity if defined, or resorts to the default serialized CPU mapping otherwise.

For IPsec packet offload mode, the order of TC offload and IPsec offload on the same netdevice is not aligned with the order in the non-offload software.

The IPsec encryption is done at the last, so add new prio for IPsec offload in FDB, and put it just lower than the slow path prio and higher than the per-vport prio. Three levels are added for TX. The first one is for ip xfrm policy. The sa table is created in the second level for ip xfrm state. The status table is created at the last to count the number of packets encrypted. The rules, which forward packets to uplink, are changed to forward them to IPsec TX tables first. These rules are restored after those tables are destroyed, which is done immediately when there is no reference to them, just as what does in legacy mode. The support for slow path is added here, by refreshing uplink's channels. But, the handling for TC fast path, which is more complicated, will be added later.
