2018-11-17pcap-based dispatch tracerDave Barach1-1/+1
To facilitate dispatch trajectory tracing, vlib_buffer_t decoding, etc. through Wireshark Change-Id: I31356b9fa1f40cba8830aaf10a86a9fbb7546438 Signed-off-by: Dave Barach <dave@barachs.net>
2018-11-05Enable atomic swap and store macro with acquire and release orderingSirshak Das1-3/+7
Add atomic swap and store macro with acquire and release ordering respectively. Variable in question is interupt_pending variable which is used as guard variable by input nodes to process the device queue. Atomic Swap is used with Acquire ordering as writes or reads following this in program order should not be reordered before the swap. Atomic Store is used with Release ordering, as post store the node is added to pending list.

2017-06-29Fix SIGBUS on aarch64Christophe Fontaine1-1/+1
A call to 'clib_smp_swap (&((dq)->interrupt_pending), 0)' was creating a SIGBUS. Instead of making dq->interrupt_pending aligned on 64bits, we reduce the size from uword (u64) to u32, as the number of pending interrupts will never go above max of u32.

2017-04-06Use thread local storage for thread indexDamjan Marion1-9/+9
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.

2017-03-20vnet: add device-input threadplacement infraDamjan Marion1-0/+45
This change adds two new debug CLI command: - "show interface placmenet" to display which thread (main or worker) is responsible for processing interface rx queue vpp# show interface placement Thread 0 (vpp_main): node af-packet-input: host-vpp1 queue 0 Thread 1 (vpp_wk_0): node af-packet-input: host-virbr0 queue 0 Thread 2 (vpp_wk_1): node af-packet-input: host-vpp2 queue 0 host-lxcbr0 queue 0 - "set interface placmenet" to assign thread (main or worker) which process specific interface rx queue vpp# set interface placement host-vpp1 queue 0 main Change-Id: Id4dd00cf2b05e10fae2125ac7cb4411b446c5e9c Signed-off-by: Damjan Marion <damarion@cisco.com>
