Saeed Mahameed says: ==================== Mellanox, mlx5 next updates 2018-08-09 This series includes mlx5 core driver updates and mostly simple cleanups. From Denis: Use max #EQs reported by firmware to request MSIX vectors. From Eli: Trivial cleanups, unused arguments/functions and reduce command polling interval when command interface is in polling mode. From Eran: Rename vport state enums, to better reflect their actual usage. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Use cond_resched() instead of usleep_range() to decrease the time between polling attempts thus reducing overall driver load time. Below is a comparison before and after the change, of loading eight virtual functions. Before: real 0m8.785s user 0m0.093s sys 0m0.090s After: real 0m5.730s user 0m0.097s sys 0m0.087s Signed-off-by:

Modify and query vport state commands share the same admin_state and op_mod values, rename the enums to fit them both. In addition, remove the esw prefix from the admin state enum as this also applied for vnic. Signed-off-by:

New firmware has defined new HCA capability field called "max_num_eqs", that is the number of available EQs after subtracting reserved FW EQs. Before this capability the FW reported the EQ number in "log_max_eqs", the reported value also contained FW reserved EQs, but the driver might be failing to load on 320 cpus systems due to the fact that FW reserved EQs were not available to the driver. Now the driver has to obtain max_num_eqs value from new FW to get real number of EQs available. Signed-off-by:

This patch adds missing rcu_assign_pointer()/rcu_dereference() to used rcu pointers. There was already a previous commit c5d99d2b ("ieee802154: hwsim: fix rcu address annotation"), but there was more which was pointed out on my side by using newest sparse version.

This patch fixes the problem below. The problem can be reproduced by the following steps: 1) Connecting all HiNIC interfaces 2) On server side # sudo ifconfig eth0 192.168.100.1 up #Using MLX CX4 card # iperf -s 3) On client side # sudo ifconfig eth0 192.168.100.2 up #Using our HiNIC card # iperf -c 192.168.101.1 -P 10 -t 100000 after hours of testing, we will see errors: hinic 0000:05:00.0: No MGMT msg handler, mod = 0 hinic 0000:05:00.0: No MGMT msg handler, mod = 0 hinic 0000:05:00.0: No MGMT msg handler, mod = 0 hinic 0000:05:00.0: No MGMT msg handler, mod = 0 The errors are caused by the following problem. 1) The hinic_get_wqe() checks the "wq->delta" to allocate new WQEs: if (atomic_sub_return(num_wqebbs, &wq->delta) <= 0) { atomic_add(num_wqebbs, &wq->delta); return ERR_PTR(-EBUSY); } If the WQE occupies multiple pages, the shadow WQE will be used. Then the hinic_xmit_frame() fills the WQE. 2) While in parallel with 1), the free_tx_poll() checks the "wq->delta" to free old WQEs: if ((atomic_read(&wq->delta) + num_wqebbs) > wq->q_depth) return ERR_PTR(-EBUSY); There is a probability that the shadow WQE which hinic_xmit_frame() is using will be damaged by copy_wqe_to_shadow(): if (curr_pg != end_pg) { void *shadow_addr = &wq->shadow_wqe[curr_pg * wq->max_wqe_size]; copy_wqe_to_shadow(wq, shadow_addr, num_wqebbs, *cons_idx); return shadow_addr; } This can cause WQE data error and you will see the above error messages.

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in this particular case, I replaced the code comments with a proper "fall through" annotation, which is what GCC is expecting to find.
