2017-02-25Merge tag 'for-next-dma_ops' of ↵Linus Torvalds1-1/+1
git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma DMA mapping updates from Doug Ledford: "Drop IB DMA mapping code and use core DMA code instead. Bart Van Assche noted that the ib DMA mapping code was significantly similar enough to the core DMA mapping code that with a few changes it was possible to remove the IB DMA mapping code entirely and switch the RDMA stack to use the core DMA mapping code. This resulted in a nice set of cleanups, but touched the entire tree and has been kept separate for that reason." * tag 'for-next-dma_ops' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (37 commits) IB/rxe, IB/rdmavt: Use dma_virt_ops instead of duplicating it IB/core: Remove ib_device.dma_device nvme-rdma: Switch from dma_device to dev.parent RDS: net: Switch from dma_device to dev.parent IB/srpt: Modify a debug statement IB/srp: Switch from dma_device to dev.parent IB/iser: Switch from dma_device to dev.parent IB/IPoIB: Switch from dma_device to dev.parent IB/rxe: Switch from dma_device to dev.parent IB/vmw_pvrdma: Switch from dma_device to dev.parent IB/usnic: Switch from dma_device to dev.parent IB/qib: Switch from dma_device to dev.parent IB/qedr: Switch from dma_device to dev.parent IB/ocrdma: Switch from dma_device to dev.parent IB/nes: Remove a superfluous assignment statement IB/mthca: Switch from dma_device to dev.parent IB/mlx5: Switch from dma_device to dev.parent IB/mlx4: Switch from dma_device to dev.parent IB/i40iw: Remove a superfluous assignment statement IB/hns: Switch from dma_device to dev.parent ...

2016-03-10IB/rdmavt: Add support for tracing eventsDennis Dalessandro1-1/+4
This patch adds support of tracing events using the kernels built-in event tracing infrastructure. This can be extended to provide a wide range of trace and debug capabilities which have a negligible impact on performance when enabled. These should be preferred over the use of the rvt_pr* functions.

2016-03-10IB/rdmavt: Create module framework and handle driver registrationDennis Dalessandro1-0/+10
This patch introduces the basics for a new module called rdma_vt. This new driver is a software implementation of the InfiniBand verbs and aims to replace the multiple implementations that exist and duplicate each others' code. While the call to actually register the device with the IB core happens in rdma_vt, most of the work is still done in the drivers themselves. This will be changing in a follow on patch this is just laying the groundwork for this infrastructure.
