2017-10-04dpdk: use vpp physmem allocator for dpdk buffersDamjan Marion1-19/+66
This allows us to have single contignuous allocation for DPDK buffers with single mmap FD, so buffer memory can be easily shared with diffrent process. As a consequence dpdk socket-mem is no longer in charge for allocating buffer memory, but still we need some space allocated for dpdk structures so default socket-mem is reduced form 256 to 64 MB. For a default of 16K buffers per numa node, physmem allocation is now 40MB, so basically this change reduces footprint from 256MB per socket to 48 (64 + 40).

2017-07-13dpdk: fix dpdk_buffer_pool_create nameChris Luke1-1/+1
- vnet_buffer_pool_create should probably be named dpdk_buffer_pool_create since that is what it does. - Its prototype should also be in a DPDK plugin header, not in vlib/buffer_funcs.h, since the implementation is in the plugin and nobody else should be calling it.

2017-07-10vlib: store buffer memory information in the buffer_mainDamjan Marion1-65/+4
Currently, buffer index is calculated as a offset to the physmem region shifted by log2_cacheline size. When DPDK is used we "hack" physmem data with information taken from dpdk mempool. This makes physmem code not usable with DPDK. This change makes buffer memory start and size independent of physmem basically allowing physmem to be used when DPDK plugin is loaded.

2017-04-06Use thread local storage for thread indexDamjan Marion1-1/+1
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.
