Cover letter [PATCH rdma-next V1 00/10] ODP Fixes and Improvements
Hi Doug,
Please find the following patch set from Artemy. This patch set fixes and extends ODP support.
This patch set has the following steps:
1. Code simplification for all IB drivers.
2. Three fixes to existing ODP code.
3. Adds generic infrastructure for regions consisting of physically contiguous chunks of arbitrary order. Utilizing this infrastructure added specific treatment to ODP MRs allocated with MAP_HUGETLB.
4. Adds ODP suport to Memory Windows (MW). Memory windows allow the application to have more flexible control over access to its memory. The operation of associating an MW with an MR is called binding. When MW is bound to ODP MR it may cause page fault which should be properly handled.
Thanks
