Subject: [PATCH 0/4] numa, iommu/smmu: IOMMU/SMMU driver optimization for NUMA systems
Date: Thu, 21 Sep 2017 14:29:18 +0530 [thread overview]
Message-ID: <20170921085922.11659-1-ganapatrao.kulkarni@cavium.com> (raw)
Adding numa aware memory allocations used for iommu dma allocation and
memory allocated for SMMU stream tables, page walk tables and command queues.
With this patch, iperf testing on ThunderX2, with 40G NIC card on
NODE 1 PCI shown same performance(around 30% improvement) as NODE 0.
Ganapatrao Kulkarni (4):
mm: move function alloc_pages_exact_nid out of __meminit
numa, iommu/io-pgtable-arm: Use NUMA aware memory allocation for smmu
translation tables
iommu/arm-smmu-v3: Use NUMA memory allocations for stream tables and
comamnd queues
iommu/dma, numa: Use NUMA aware memory allocations in
__iommu_dma_alloc_pages
