2019-07-18vlib: convert frame_index into real pointersAndreas Schultz1-1/+1
The fast path almost always has to deal with the real pointers. Deriving the frame pointer from a frame_index requires a load of the 32bit frame_index from memory, another 64bit load of the heap base pointer and some calculations. Lets store the full pointer instead and do a single 64bit load only. This helps avoiding problems when the heap is grown and frames are allocated below vm->heap_aligned_base.

2019-01-30buffers: major cleanup and improvementsDamjan Marion1-1/+4
This patch introduces following changes: - deprecated free lists which are not used and not compatible with external buffer managers (i.e. DPDK) - introduces native support for per-numa buffer pools - significantly improves performance of buffer alloc and free Change-Id: I4a8e723ae47056717afd6cac0efe87cb731b5be7 Signed-off-by: Damjan Marion <damarion@cisco.com>

2018-09-27avf: may crash if failed to allocate buffers to ringSteven1-1/+1
In avf_rxq_refill, we invoke vlib_buffer_alloc_to_ring which may fill buffers from the end of the ring and continue to the beginning of the ring. If we fill some in the end and continue to fill some in the beginning, but does not have enough buffers to fill the whole request, n_alloc returns a value which is not equal to n_refill to indicate partial refill. We don't like partial refill and invoke vlib_buffer_free to get rid of the buffers that just got refilled. However, vlib_buffer_free API is to free the buffers from the slot continuously. It does not know how to free some from rxq->bufs[slot], and then continue to free the rest when it reaches the end of the ring. The fix is to use vlib_buffer_free_from_ring which is smart enough to figure that stuff out. Change-Id: I93c28e0b0d8d8f22c321d1a5912e00c27b4e2e8d Signed-off-by: Steven <sluong@cisco.com>
2018-08-13Multiarch handling in different constructor macrosDamjan Marion1-2/+0
This significantly reduces need for ... in multiarch code. Simply constructor macros will jost create static unused entry if CLIB_MARCH_VARIANT is defined and that will be optimized out by compiler.
