Up until this point it wasn't possible to activate IB representors when switching to switchdev mode, remove this limitation. We trigger reload of the PF IB interface in order to make sure that already allocated resources are invalid and new resources will be opened correctly with all the limitations of switchdev mode applied (only raw packet capabilities, without RoCE). We also move the remove/add to a place where the E-Switch mode is set/unset to better control when to trigger this action, this will allow the IB side to start in the correct mode. For better code reuse, create a function which reloads an interface and export it.

This commit adds full support for IB representor: 1) Representors profile, We add two new profiles: nic_rep_profile - This profile will be used to create an IB device that represents the PF/UPLINK. rep_profile - This profile will be used to create an IB device that represents VFs. Each VF will be its own representor. 2) Proper load/unload callbacks, Those are called by the E-Switch when moving to/from switchdev mode. 3) Different flow DB handling for when we in switchdev mode.

When enabling many VFs and switching to switchdev mode, the total amount of mkeys we try to allocate when loading representors is very large and may cause timeouts on allocations, the same issues was observed on VFs and we employ the same fix that was done for them.

Under switchdev mode we insert an eswitch miss rule causing any unmatched traffic to be sent towards the PF vport. This miss rule can be optimized if we break it to two, one case is for multicast traffic and the other for unicast. Breaking the miss rule into two (unicast and multicast) allows the firmware to program the hardware in a more efficient way. Using ConncetX-5 Ex with IXIA and testpmd (which use IB representors): IXIA -> NIC -> PF -> IB representor -> NIC -> VF: - Without this optimization: 9.2 MPPS. - With this optimization: 18 MPPS.

For now lets start with 31 per IB representor and if needed increase in the future.

The current implementation of create CQ requires contiguous memory, such requirement is problematic once the memory is fragmented or the system is low in memory, it causes for failures in dma_zalloc_coherent(). This patch implements new scheme of fragmented CQ to overcome this issue by introducing new type: 'struct mlx5_frag_buf_ctrl' to allocate fragmented buffers, rather than contiguous ones. Base the Completion Queues (CQs) on this new fragmented buffer. It fixes following crashes: kworker/29:0: page allocation failure: order:6, mode:0x80d0 CPU: 29 PID: 8374 Comm: kworker/29:0 Tainted: G OE 3.10.0 Workqueue: ib_cm cm_work_handler [ib_cm] Call Trace: [<>] dump_stack+0x19/0x1b [<>] warn_alloc_failed+0x110/0x180 [<>] __alloc_pages_slowpath+0x6b7/0x725 [<>] __alloc_pages_nodemask+0x405/0x420 [<>] dma_generic_alloc_coherent+0x8f/0x140 [<>] x86_swiotlb_alloc_coherent+0x21/0x50 [<>] mlx5_dma_zalloc_coherent_node+0xad/0x110 [mlx5_core] [<>] ? mlx5_db_alloc_node+0x69/0x1b0 [mlx5_core] [<>] mlx5_buf_alloc_node+0x3e/0xa0 [mlx5_core] [<>] mlx5_buf_alloc+0x14/0x20 [mlx5_core] [<>] create_cq_kernel+0x90/0x1f0 [mlx5_ib] [<>] mlx5_ib_create_cq+0x3b0/0x4e0 [mlx5_ib] Signed-off-by: NYonatan Cohen <yonatanc@mellanox.com> Reviewed-by: NTariq Toukan <tariqt@mellanox.com> Signed-off-by: NLeon Romanovsky <leon@kernel.org> Signed-off-by: NSaeed Mahameed <saeedm@mellanox.com>

Before this patch the driver had one CQ database protected via one spinlock, this spinlock is meant to synchronize between CQ adding/removing and CQ IRQ interrupt handling. On a system with large number of CPUs and on a work load that requires lots of interrupts, this global spinlock becomes a very nasty hotspot and introduces a contention between the active cores, which will significantly hurt performance and becomes a bottleneck that prevents seamless cpu scaling. To solve this we simply move the CQ database and its spinlock to be per EQ (IRQ), thus per core.

NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al.

59f47eff ("powerpc/pci: Use of_irq_parse_and_map_pci() helper") replaced of_irq_parse_pci() + irq_create_of_mapping() with of_irq_parse_and_map_pci(), but neglected to capture the virq returned by irq_create_of_mapping(), so virq remained zero, which caused INTx configuration to fail. Save the virq value returned by of_irq_parse_and_map_pci() and correct the virq declaration to match the of_irq_parse_and_map_pci() signature.
