2020-06-03vlib: improve node interrupt handlingDamjan Marion1-5/+12
- add ability to pass data together with interrupt - avoid locking for local interrupts (same thread) Type: improvement Change-Id: I73a2ab2e716bb887a1f02c87788ae83e329f9b40 Signed-off-by: Damjan Marion <damarion@cisco.com>
2020-05-20vlib: mmap process stacksDamjan Marion1-25/+4
Instead of allocating stack from the main heap, this patch mmaps stack memory together with guard page. This aproach reduces main heap usage, and stack memory is prefaulted on demand, so bigger process stacks will have zero impact on memory usage as long as stack memory is not needed for real. In addition, it fixes issue with systems which have bigger default page size (observed with 65536).

2020-04-28vlib: startup multi-arch variant configurationRay Kinsella1-0/+2
Support for startup node multi-arch variant selection through startup.conf. This is to facilitate unit, functional testing and benchmarking of non-default multi-arch variant node code path. Also added parameters to make test, to specific using multi-arch variants in unit testing.

2019-07-23vlib: address vlib_error_t scaling issueDave Barach1-0/+19
Encoding the vpp node index into the vlib_error_t as a 10-bit quantity limits us to 1K graph nodes. Unfortunately, a few nodes need 6 bit per-node error codes. Only a very few nodes have so many counters. It turns out that there are about 2K total error counters in the system, which is (approximately) the maximum error heap index. The current (index,code) encoding limits the number of interfaces to around 250, since each interface has two associated graph nodes and we have about 500 "normal, interior" graph node This patch adds an error-index to node-index map, so we can store error heap indices directly in the vlib_buffer_t.

2019-07-18vlib: convert frame_index into real pointersAndreas Schultz1-6/+5
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.

2019-02-02Deprecate old mutliarch code, phase 1Damjan Marion1-24/+2
It is causing compilation sloness with gcc-7 so removing it before it was originally planned. So far macros are left in the tree so we can know which nodes to convert to new multiarch code. Change-Id: Idb14622ca61fdce1eba59723b20d98715b7971e6 Signed-off-by: Damjan Marion <damarion@cisco.com>
2019-01-24perfmon plugin: 2-way parallel stat collectionDave Barach1-2/+4
As a FUD reduction measure, this patch implements 2-way parallel counter collection. Synthetic stat component counter pairs run at the same time. Running two counters (of any kind) at the same time naturally reduces the aggregate time required by an approximate factor-of-2, depending on whether an even or odd number of stats have been requested. I don't completely buy the argument that computing synthetic stats such as instructions-per-clock will be inaccurate if component counter values are collected sequentially. Given uniform traffic pattern, it must make no difference. As the collection interval increases, the difference between serial and parallel component counter collection will approach zero, see also the Central Limit theorem.

The buffer index allows downstream consumers of these data to easily filter/track single packets as they traverse the forwarding graph. FWIW, the 32-bit buffer index is stored in big endian format. As of this writing, major version = 1, minor version = 0. Nstrings will be either 4 or 5. Here is the current set of protocol hints: typedef enum { VLIB_NODE_PROTO_HINT_NONE = 0, VLIB_NODE_PROTO_HINT_ETHERNET, VLIB_NODE_PROTO_HINT_IP4, VLIB_NODE_PROTO_HINT_IP6, VLIB_NODE_PROTO_HINT_TCP, VLIB_NODE_PROTO_HINT_UDP, VLIB_NODE_N_PROTO_HINTS, } vlib_node_proto_hint_t; Example: VLIB_NODE_PROTO_HINT_IP6 means that the first octet of packet data SHOULD be 0x60, and should begin an ipv6 packet header.

2017-04-06Use thread local storage for thread indexDamjan Marion1-3/+3
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.
