Subject: [PATCH v2 0/6] Automatic affinity settings for nvme over rdma
Date: Thu, 6 Apr 2017 13:36:32 +0300 [thread overview]
Message-ID: <1491474998-16423-1-git-send-email-sagi@grimberg.me> (raw)
This patch set is aiming to automatically find the optimal
queue <-> irq multi-queue assignments in storage ULPs (demonstrated
on nvme-rdma) based on the underlying rdma device irq affinity
settings.
Changes from v1:
- Removed mlx5e_get_cpu as Christoph suggested
- Fixed up nvme-rdma queue comp_vector selection to get a better match
- Added a comment on why we limit on @dev->num_comp_vectors
- rebased to Jens's for-4.12/block
- Collected review tags
Sagi Grimberg (6):
mlx5: convert to generic pci_alloc_irq_vectors
mlx5: move affinity hints assignments to generic code
RDMA/core: expose affinity mappings per completion vector
mlx5: support ->get_vector_affinity
block: Add rdma affinity based queue mapping helper
nvme-rdma: use intelligent affinity based queue mappings
