phylink wants to know when the MAC layers notices a change in the link. For the 6390 family, this is a change in the SERDES state. Add interrupt support for the SERDES interface used to implement SGMII/1000Base-X/2500Base-X. This is currently limited to ports 9 and 10. Support for the 10G SERDES and other ports will be added later, building on this basic framework. Signed-off-by:

An up coming change will register interrupts for individual switch ports, using the mv88e6xxx_port as the interrupt context information. Add members to the mv88e6xxx_port structure so we can link it back to the mv88e6xxx_chip member the port belongs to and the port number of the port. Signed-off-by:

The 6390 family has a number of SERDES interfaces per port. When the cmode changes, eg 1000Base-X to XAUI, the SERDES interface in use will also change. Power down the old SERDES interface and power up the new SERDES interface. Signed-off-by:

The 6390 has two SERDES interfaces, used by ports 9 and 10. The 6390X has eight SERDES interfaces. These allow ports 9 and 10 to do 10G. Or if lower speeds are used, some of the SERDES interfaces can be used by ports 2-8 for 1000Base-X. Signed-off-by:

The 6390 family has 8 SERDES lanes. What ports use these lanes depends on how ports 9 and 10 are configured. If 9 and 10 does not make use of a line, one of the lower ports can use it. Add a function to return the lane a port is using, if any, and simplify the code to power up/down the lane. Signed-off-by:

Add a helper for MAC drivers to use in their validate callback to deal with 2500BaseX vs 1000BaseX modes, where the hardware supports both but it is not possible to automatically select between them. This helper defaults to 1000BaseX, as that is the 802.3 standard, and will allow users to select 2500BaseX either by forcing the speed if AN is disabled, or by changing the advertising mask if AN is enabled. Disabling AN is not recommended as it is only the speed that we're interested in controlling, not the duplex or pause mode parameters. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Various updates Patches 1-3 update the driver to use a new firmware version. Due to a recently discovered issue, the version (and future ones) does not support matching on VLAN ID at egress. This is enforced in the driver and reported back to the user via extack. Patch 4 adds a new selftest for the recently introduced algorithmic TCAM. Patch 5 converts the driver to use SPDX identifiers. Patches 6-7 fix a bug in ethtool stats reporting and expose counters for all 16 TCs, following recent MC-aware changes that utilize TCs 8-15. ==================== Signed-off-by: -
Petr Machata authored
Before MC-aware mode was enabled in commit 7b819530 ("mlxsw: spectrum: Configure MC-aware mode on mlxsw ports"), only 8 traffic classes were used. Under MC-aware regime, however, besides using TCs 0-7 for UC traffic, it additionally uses TCs 8-15 for BUM traffic. It is therefore desirable to show counters for these TCs as well. Update ethtool stats pool length, mlxsw_sp_port_get_strings() and mlxsw_sp_port_get_stats() to include artifacts for all 16 TCs. For consistency and simplicity, expose tc_no_buffer_discard_uc_tc for BUM TCs as well, even though it ought to stay at 0 all the time. Signed-off-by:

The function mlxsw_sp_port_get_sset_count() is supposed to return the total number of ethtool strings that mlxsw supports. Specifically for names of statistic counters (the only string type that mlxsw supports as of now), that number is stored in MLXSW_SP_PORT_ETHTOOL_STATS_LEN. However, when adding RFC-2891 counters, that define wasn't updated to include the new counters. As a result, ethtool snips out the counters towards the end of the list, which contains per-TC counters, and only the first three traffic classes end up being reported. Fix by adding MLXSW_SP_PORT_HW_RFC_2819_STATS_LEN as appropriate. Fixes: 1222d15a ("mlxsw: spectrum: Expose counters for various packet sizes") Signed-off-by:

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.

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 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.
