Commit 25c13324d03d ("IB/mlx5: Add steering SW ICM device memory type") breaks i386 build by introducing three 64-bit divisions. As the divisor is MLX5_SW_ICM_BLOCK_SIZE() which is always a power of 2, we can replace the division with bit operations.

2019-04-24Merge branch 'rdma_mmap' into rdma.git for-nextJason Gunthorpe1-10/+13
Jason Gunthorpe says: ==================== Upon review it turns out there are some long standing problems in BAR mapping area: * BAR pages intended for read-only can be switched to writable via mprotect. * Missing use of rdma_user_mmap_io for the mlx5 clock BAR page. * Disassociate causes SIGBUS when touching the pages. * CPU pages are being mapped through to the process via remap_pfn_range instead of the more appropriate vm_insert_page, causing weird behaviors during disassociation. This series adds the missing VM_* flag manipulation, adds faulting a zero page for disassociation and revises the CPU page mappings to use vm_insert_page. ==================== For dependencies this branch is based on for-rc from git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git * branch 'rdma_mmap': RDMA: Remove rdma_user_mmap_page RDMA/mlx5: Use get_zeroed_page() for clock_info RDMA/ucontext: Fix regression with disassociate RDMA/mlx5: Use rdma_user_map_io for mapping BAR pages RDMA/mlx5: Do not allow the user to write to the clock page Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>

2019-04-22RDMA/mlx5: Initialize roce port info before multiport master initMark Bloch1-7/+3
When working in mutliport RoCE mode it is possible to attach a slave before the master. In that case the slave is waiting for a master to be attached. When the master is attached it goes over the list of waiting slaves, finds a slave that is compatible and tries to bind it to itself. The call stack is: mlx5_ib_init_multiport_master() -> mlx5_ib_bind_slave_port() In the bind function we will create a netdev notifier, but this is done before we initialize the RoCE structure (this is done at a later stage by the master in the ROCE stage). Once events are delivered to that notifier we will use mlx5_ib_get_native_port_mdev() to get the actual port and as the native port is zero we will access an invalid index in the port structure. Move the RoCE structure initialization to an earlier stage.

2019-02-21IB/mlx5: Protect against prefetch of invalid MRMoni Shoua1-12/+1
When deferring a prefetch request we need to protect against MR or PD being destroyed while the request is still enqueued. The first step is to validate that PD owns the lkey that describes the MR and that the MR that the lkey refers to is owned by that PD. The second step is to dequeue all requests when MR is destroyed. Since PD can't be destroyed while it owns MRs it is guaranteed that when a worker wakes up the request it refers to is still valid. Now, it is possible to refrain from taking a reference on the device since it is assured to be present as pd. While that, replace the dedicated ordered workqueue with the system unbound workqueue to reuse an existing resource and improve performance. This will also fix a bug of queueing to the wrong workqueue.

2019-02-14IB/mlx5: Add support for 50Gbps per lane link modesAya Levin1-5/+61
Driver now supports new link modes: 50Gbps per lane support for 50G/100G/200G. This patch reads the correct field (legacy vs. extended) based on a FW indication bit, and adds a translation function (link modes to IB width and speed) to the new link modes.

2019-02-14net/mlx5: Add support to ext_* fields introduced in Port Type and Speed registerAya Levin1-1/+2
This patch exposes new link modes (including 50Gbps per lane), and ext_* fields which describes the new link modes in Port Type and Speed register (PTYS). Access functions, translation functions (speed <-> HW bits) and link max speed function were modified.

2019-02-14net/mlx5: Refactor queries to speed fields in Port Type and Speed registerAya Levin1-2/+4
This patch fascicles queries to speed related fields in Port Type and Speed register (PTYS) into a single API. I addition, this patch refactors functions which serves only Ethernet driver: remove the protocol type as an input parameter, move code from 'core' directory into 'en' directory and add 'eth' prefix to the function's name. The patch also encapsulates functions that are not used outside the Ethernet driver removes redundant include files.
