368c0159 - RDMA/umem: Support importing dma-buf as user memory region

Tue, 15 Dec 2020 21:27:13 +0000

RDMA/umem: Support importing dma-buf as user memory regionDma-buf is a standard cross-driver buffer sharing mechanism that can beused 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 bufferallocation. When the buffer is registered as a memory region, the filedescriptor is passed to the RDMA driver along with other parameters.Implement the common code for importing dma-buf object and mapping dma-bufpages.Link: https://lore.kernel.org/r/1608067636-98073-2-git-send-email-jianxin.xiong@intel.comSigned-off-by: Jianxin Xiong Reviewed-by: Sean Hefty Acked-by: Michael J.

36f30e48 - IB/core: Improve ODP to use hmm_range_fault()

Wed, 30 Sep 2020 16:38:25 +0000

IB/core: Improve ODP to use hmm_range_fault()Move to use hmm_range_fault() instead of get_user_pags_remote() to improveperformance 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 faultsin the system with it's snapshot mode, this will be introduced in nextpatches from this series.As part of this, cleanup some flows and use the required data structuresto work with hmm_range_fault().Link: https://lore.kernel.org/r/20200930163828.1336747-2-leon@kernel.orgSigned-off-by: Yishai Hadas Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe List of files: /linux-6.15/drivers/infiniband/Kconfig

7cc2e18f - RDMA/odp: Use the common interval tree library instead of generic

Mon, 19 Aug 2019 11:16:59 +0000

RDMA/odp: Use the common interval tree library instead of genericODP is working with userspace VA's in the interval tree which always fitinto an unsigned long, so we can use the common code.This comes at a cost of a 16 byte increase in ib_umem_odp struct size dueto storing the interval tree start/last in addition to the umemaddr/length. However these values were computed and are performancecritical for the interval lookup, so this seems like a worthwhile tradeoff.Removes 2k of .text from the kernel.Link: https://lore.kernel.org/r/20190819111710.18440-2-leon@kernel.orgSigned-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe List of files: /linux-6.15/drivers/infiniband/Kconfig

rdma: Remove nesThis driver was first merged over 10 years ago and has not seen majoractivity by the authors in the last 7 years. However, in that time it hasbeen patched 150 times to adapt it to changing kernel APIs.Further, the hardware has several issues, like not supporting 64 bit DMA,that make it rather uninteresting for use with modern systems and RDMA.Signed-off-by: Jason Gunthorpe Reviewed-by: Leon Romanovsky Reviewed-by: Shiraz Saleem Signed-off-by: Doug Ledford List of files: /linux-6.15/drivers/infiniband/Kconfig
