2019-04-29net/mlx5: Separate and generalize dma device from pci deviceVu Pham1-4/+6
The mlx5 Sub-Function (SF) sub device will be introduced in subsequent patches. It will be created as mediated device and belong to mdev bus. It is necessary to treat dma operations on PF, VF and SF in uniform way, hence reduce the dependency on pdev pci dev struct and work directly out of newly introduced 'struct device' from previous patch. This patch does not change any functionality. Signed-off-by: Vu Pham <[email protected]> Reviewed-by: Parav Pandit <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>

2019-04-24Merge branch 'rdma_mmap' into rdma.git for-nextJason Gunthorpe2-14/+20
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 <[email protected]>

Upon further research drivers that want this should simply call the core function vm_insert_page().

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.

2019-04-08drivers: Remove explicit invocations of mmiowb()Will Deacon1-1/+0
mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.
