RDMA/qib: Remove outdated driver

2025-06-17T17:05:53Z

The qib Infiniband device has long been decommissioned from distros and unsupported by the company. We have kept it going in a compile only mode for a while now and it's time to remove the driver. It has a number of issues that are never going to be addressed and is a hindrance to improving hfi1 and rdmavt.

RDMA: Disable IB HW for UML

2022-12-04T13:22:03Z

Disable all of drivers/infiniband/hw/ and rdmavt for UML builds until someone needs it and provides patches to support it. This prevents build errors in hw/qib/qib_wc_x86_64.c.

Add Kconfig and Makefile to build irdma driver. Remove i40iw driver and add an alias in irdma. Remove legacy exported symbols i40e_register_client and i40e_unregister_client from i40e as they are no longer used. irdma is the replacement driver that supports X722.

RDMA/umem: Support importing dma-buf as user memory region

2021-01-20T20:07:52Z

Dma-buf is a standard cross-driver buffer sharing mechanism that can be used to support peer-to-peer access from RDMA devices. Device memory exported via dma-buf is associated with a file descriptor. This is passed to the user space as a property associated with the buffer allocation. When the buffer is registered as a memory region, the file descriptor is passed to the RDMA driver along with other parameters. Implement the common code for importing dma-buf object and mapping dma-buf pages.

RMDA/sw: Don't allow drivers using dma_virt_ops on highmem configs

2020-11-12T17:27:41Z

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 Signed-off-by: Jason Gunthorpe

IB/core: Improve ODP to use hmm_range_fault()

2020-10-01T19:39:54Z

Move to use hmm_range_fault() instead of get_user_pags_remote() to improve performance in a few aspects: This includes: - Dropping the need to allocate and free memory to hold its output - No need any more to use put_page() to unpin the pages - The logic to detect contiguous pages is done based on the returned order, no need to run per page and evaluate. In addition, moving to use hmm_range_fault() enables to reduce page faults in the system with it's snapshot mode, this will be introduced in next patches from this series. As part of this, cleanup some flows and use the required data structures to work with hmm_range_fault().
