2021-04-18vppinfra: remove linux/syscall.hDamjan Marion1-43/+27
For portabiliy reasons it is better to have all wrapped in clib code. I.e. instead of using getcpu() we have clib_get_current_numa_node () and clib_get_current_cpu_id(). Type: refactor Change-Id: I29b52d7f29bc7f93873402c4070561f564b71c63 Signed-off-by: Damjan Marion <damarion@cisco.com>

2020-04-21vppinfra: bihash improvementsDave Barach1-23/+6
Template instances can allocate BIHASH_KVP_PER_PAGE data records tangent to the bucket, to remove a dependent read / prefetch. Template instances can ask for immediate memory allocation, to avoid several branches in the lookup path. Clean up l2 fib, gpb plugin codes: use clib_bihash_get_bucket(...) Use hugepages for bihash allocation arenas Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Damjan Marion <damarion@cisco.com> Change-Id: I92fc11bc58e48d84e2d61f44580916dd1c56361c

2018-10-25pmalloc: don't lock 4K pages if we don't have access to pagemapDamjan Marion1-6/+26
Without pagemap access only way to do DMA to physmem is by using IOMMU. In such case VFIO will take care for preventing paging of such memory so we don't need to lock here. Change-Id: Ica9c20659fba3ea3c96202eb5f7d29c43b313fa9 Signed-off-by: Damjan Marion <damarion@cisco.com>
