RDMA/siw: Add missing Kconfig selections The SoftiWARP Kconfig is missing "select" for CRYPTO and CRYPTO_CRC32C. In addition, it improperly "depends on" LIBCRC32C, this should be a "select", similar to net/sctp and others. As a dependency, SIW fails to appear in generic configurations.

RDMA/core: remove use of dma_virt_ops Use the ib_dma_* helpers to skip the DMA translation instead. This removes the last user if dma_virt_ops and keeps the weird layering violation inside the RDMA core instead of burderning the DMA mapping subsystems with it. This also means the software RDMA drivers now don't have to mess with DMA parameters that are not relevant to them at all, and that in the future we can use PCI P2P transfers even for software RDMA, as there is no first fake layer of DMA mapping that the P2P DMA support.

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>

RDMA/siw: Change CQ flags from 64->32 bits This patch changes the driver/user shared (mmapped) CQ notification flags field from unsigned 64-bits size to unsigned 32-bits size. This enables building siw on 32-bit architectures. This patch changes the siw-abi, but as siw was only just merged in this merge window cycle, there are no released kernels with the prior abi. We are making no attempt to be binary compatible with siw user space libraries prior to the merge of siw into the upstream kernel, only moving forward with upstream kernels and upstream rdma-core provided siw libraries are we guaranteeing compatibility.

RMDA/siw: Require a 64 bit arch The new siw driver fails to build on i386 with drivers/infiniband/sw/siw/siw_qp.c:1025:3: error: invalid output size for constraint '+q' smp_store_mb(*cq->notify, SIW_NOTIFY_NOT); As it is using 64 bit values with the smp_store_mb. Since the entire scheme here seems questionable, and we are in the merge window, fix the compile failures by disabling 32 bit support on this driver. A proper fix will be reviewed post merge window.

rdma/siw: Add missing dependencies on LIBCRC32C and DMA_VIRT_OPS If LIBCRC32C and DMA_VIRT_OPS are not enabled: drivers/infiniband/sw/siw/siw_main.o: In function `siw_newlink': siw_main.c:(.text+0x35c): undefined reference to `dma_virt_ops' drivers/infiniband/sw/siw/siw_qp_rx.o: In function `siw_csum_update': siw_qp_rx.c:(.text+0x16): undefined reference to `crc32c' Fix the first issue by adding a select of DMA_VIRT_OPS. Fix the second issue by replacing the unneeded dependency on CRYPTO_CRC32 by a dependency on LIBCRC32C.
