IB/rdmavt: Create module framework and handle driver registration 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.

RMDA/sw: Don't allow drivers using dma_virt_ops on highmem configs dma_virt_ops requires that all pages have a kernel virtual address. Introduce a INFINIBAND_VIRT_DMA Kconfig symbol that depends on !HIGHMEM and make all three drivers depend on the new symbol. Also remove the ARCH_DMA_ADDR_T_64BIT dependency, which has been obsolete since commit 4965a68780c5 ("arch: define the ARCH_DMA_ADDR_T_64BIT config symbol in lib/Kconfig") Fixes: 551199aca1c3 ("lib/dma-virt: Add dma_virt_ops") Link: https://lore.kernel.org/r/20201106181941.1878556-2-hch@lst.de Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> 2020-11-06 18:19:32 +00:00			`depends on INFINIBAND_VIRT_DMA`

IB: Move PCI dependency from root KConfig to HW's KConfigs No reason to have dependency on PCI for the entire infiniband stack so move it to KConfig of only the drivers that actually using PCI.

IB/rxe, IB/rdmavt: Use dma_virt_ops instead of duplicating it Make the rxe and rdmavt drivers use dma_virt_ops. Update the comments that refer to the source files removed by this patch. Remove struct ib_dma_mapping_ops. Remove ib_device.dma_ops.

treewide: replace '---help---' in Kconfig files with 'help' Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig' \| xargs sed -i 's/^[[:space:]]---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> 2020-06-13 16:50:22 +00:00			`help`
