2022-05-11dpdk: clear the RTE_MEMPOOL_F_NON_IOMohammed Hawari1-0/+3
This mempool flag should be cleared when the mempool is populated, to reproduce the behaviour of rte_mempool_populate_iova in DPDK 22.03 Change-Id: I4c0e07efca9df2e472e8e393689127c01cf66da2 Signed-off-by: Mohammed Hawari <mohammed@hawari.fr> Type: fix Fixes: 2f132efc3cafde5a0dd01ef8a91606528970cdf7
2022-03-14crypto: Enabling IOMMU DMA translation table update for QAT cardGovindarajan1-1/+2
With DPDK plugin, VPP does the DMA page map in IOMMU, only when DPDK supported ethernet devices are present. As a result, Mellanox NIC and QAT combo doesn't work. As part of this fix, DPDK supported crypto device check is added to do the DMA page map.

Change dpdk_ops_vpp_get_count() return value from 0 to actual available pool size; For some drivers/envs(azure,vmbus) rx_queue size will be zero and the only 1 element will be created (0 + 1) When more than one packet will arrive, it will cause SEGFAULT Type: fix Signed-off-by: Vladimir Ratnikov <vratnikov@netgate.com> Change-Id: Ibe7da6acc91200bec33d99f580044456d8984110

2019-09-16dpdk: initialize rte_mbuf during mempool dequeueDamjan Marion1-1/+44
In some cases it may happen that buffer is allocated by DPDK, and freed by VPP native code. In such cases dpdk metadata is not reset, so we need to do that during mempool dequeue. Template approach is taken to reduce cost of that operation. Type: fix Fixes: 910d369 Change-Id: Ic239007cfc8fbceb965021c56963cda9d53f63be Signed-off-by: Damjan Marion <damarion@cisco.com>

2018-05-29dpdk: mempool priv intialization must be done before releasing buffers to poolSachin Saxena1-8/+7
- Currently mempool priv size is getting initialized after releasing buffers to pool. This is causing mismatch in expected & real metadata size value and buffers are getting released with wrong offset. (when metadata offset is in use for a given platform) - Since private data size is 0 initially, metadata size don't include space for VLIB_BUFFER_HDR.
