From 792c4e9d0bbb53b34bf1c07c2ef25609d746c57d Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Thu, 20 Jun 2019 07:03:47 +0000 Subject: net/mlx5: Convert mkey_table to XArray The lock protecting the data structure does not need to be an rwlock. The only read access to the lock is in an error path, and if that's limiting your scalability, you have bigger performance problems. Eliminate mlx5_mkey_table in favour of using the xarray directly. reg_mr_callback must use GFP_ATOMIC for allocating XArray nodes as it may be called in interrupt context. This also fixes a minor bug where SRCU locking was being used on the radix tree read side, when RCU was needed too.

So we replace the match on source port with the match on metadata that was configured in ingress ACL, and that metadata will be passed further also to the NIC RX table of the eswitch manager. Introduce vport metadata matching bits and enum constants as a pre-step towards metadata matching. o metadata type C registers in the misc parameters 2 fields. o esw_uplink_ingress_acl bit in esw cap. If it set, the device supports ingress ACL for the uplink vport. o fdb_to_vport_reg_* bits in flow table cap and esw vport context, to support propagating the metadata to the nic rx through the loopback path. o flow_source in flow context, to indicate the known origin of packets. o enum constants, to support the above bits.

So we change to match on metadata instead of source vport. To do that, a rule is created in all vports and uplink ingress ACLs, to save the source vport number and vhca id in the packet's metadata in order to match on it later. The metadata register used is the first of the 32-bit type C registers. It can be used for matching and header modify operations. The higher 16 bits of this register are for vhca id, and the lower 16 ones is for vport number. This change is not for dual-port RoCE only. If HW and FW allow, the vport metadata matching is enabled by default.

While FW has no idea about what it is in the metadata, a syndrome will happen. Specify a known origin to avoid the syndrome. However, there is no functional change because ANY_VPORT (0) is filled in flow_source, the same default value as before, as a pre-step towards metadata matching for fast path. There are two other values can be filled in flow_source. When setting 0x1, packet matching this rule is from uplink, while 0x2 is for packet from other local vports.

As ECPF and host PF work in two independent hosts, it's possible that host PF OS reboots but ECPF system is still kept on and continues monitoring events from host PF. When kernel from host PF side is booting, PCI iov driver does sriov_init and compute_max_vf_buses by iterating over all valid num of VFs. This triggers FLR and generates functions changed events, even though host PF HCA is not enabled at this time. However, ECPF is not aware of this information, and still handles these events as usual. ECPF system will see massive number of reps are created, but destroyed immediately once creation finished. To eliminate this noise, a bit is added to host parameter context to indicate host PF is disabled. ECPF will not handle the VF changed event if this bit is set.
