When smmu is enable, if execute the perftest command and then use 'kill -9' to exit, follow this operation repeatedly, the kernel will have a high probability to print the following smmu event: arm-smmu-v3 arm-smmu-v3.1.auto: event 0x10 received: arm-smmu-v3 arm-smmu-v3.1.auto: 0x00007d0000000010 arm-smmu-v3 arm-smmu-v3.1.auto: 0x0000020900000080 arm-smmu-v3 arm-smmu-v3.1.auto: 0x00000000f47cf000 arm-smmu-v3 arm-smmu-v3.1.auto: 0x00000000f47cf000 This is because the hw will periodically refresh the qpc cache until the next reset. This patch fixed it by removing the action that release qpc memory in the 'hns_roce_qp_free' function. Fixes: 9a443537 ("IB/hns: Add driver files for hns RoCE driver") Signed-off-by:

The buffer size of qp which used to allocate qp buffer space for storing sqwqe and rqwqe will be the length of buffer space. The kernel driver will use the buffer address and the same size to get the user memory. The same size named buff_size of qp. According the algorithm of calculating, The size of the two is not equal when users set the max sge of sq. Fixes: b28ca7cc ("RDMA/hns: Limit extend sq sge num") Signed-off-by:

When hw resetting, there is no response from hw when driver sending cmdq. If driver still send cmdq to hw, the reset process may be blocked. So reset flag should be set to intercept the cmdq command when driver receiving "notify down" signal. Signed-off-by:

Mark Zhang authored
In manual mode a QP is bound to a counter manually. If counter is not specified then a new one will be allocated. Manual mode is enabled when user binds a QP, and disabled when the last manually bound QP is unbound. When auto-mode is turned off and there are counters left, manual mode is enabled so that the user is able to access these counters. Signed-off-by:

Since a QP can only be bound to one counter, then if it is bound to a separate counter, for backward compatibility purpose, the statistic value must be: * stat of default counter + stat of all running allocated counters + stat of all deallocated counters (history stats) Signed-off-by:

Support bind a qp with counter. If counter is null then bind the qp to the default counter. Different QP state has different operation: - RESET: Set the counter field so that it will take effective during RST2INIT change; - RTS: Issue an RTS2RTS change to update the QP counter; - Other: Set the counter field and mark the counter_pending flag, when QP is moved to RTS state and this flag is set, then issue an RTS2RTS modification to update the counter.

Introduce statistic counter as a new resource. It allows a user to monitor specific objects (e.g., QPs) by binding to a counter. In some cases a user counter resource is created with task other then "current", because its creation is done as part of rdmatool call. Signed-off-by:

Despite failure in ipoib_dev_init() we continue with initialization flow and creation of child device. It causes to the situation where this child device is added too early to parent device list.

Functions change event output data size changes when functions other than VFs will be enabled in HCA CAP. With current API, multiple callers needs to align, calculate accurate size of the output data depending on number on non VF functions enabled in the device. Instead of duplicating such math at multiple places, refactor mlx5_esw_query_functions() to return raw output allocated by itself. Caller must free the allocated memory using kvfree() as described in the function comment section. This hides calcuation within mlx5_esw_query_functions() and provides simpler API. Signed-off-by:
