2021-04-21vlib: don't inline vlib_buffer_enqueue_to_*Damjan Marion1-0/+2
Function call in this case is not bad thing, as those functions are called once per frame. Type: improvement Change-Id: I7bd61cf746b905e2c8e3085ebb2ff001c0a52da8 Signed-off-by: Damjan Marion <damarion@cisco.com>
2020-05-20vlib: mmap process stacksDamjan Marion1-0/+12
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.

2020-04-27vlib: deprecate i2c and cjDave Barach1-4/+0
i2c follows its only use case - the original 82599 driver - into extras/deprecated. cj is/was an emergency debug tool unused in several years. Move to extras/deprecated/vlib Type: refactor Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: Ib55b65373f62630db295c562974bd8f2456c3107
2020-04-13buffers: configurable buffer fault injectorDave Barach1-0/+8
When configured at compile time via the cmake VPP_BUFFER_FAULT_INJECTOR option, the buffer allocator will appear to fail a certain fraction of the time. By default, the allocator succeeds 80% of the time. Detailed command line configuration options are available, but only when the image has been compiled with cmake option described above: vlib { buffer-alloc-success-rate [0.0 ... 1.0] buffer-alloc-success-seed <nnnn> } Modify vlib_buffer_pool_create(...) so 0 is always an invalid buffer index. Debug images: add checks for bad buffer index enqueues, and also verify that f->n_vectors doesn't accidentally map one or more instances of the frame poison pattern 0xfefefefe.

2019-03-28Punt InfraNeale Ranns1-0/+4
A punt/exception path that provides: 1) clients that use the infra 2) clients can create punt reasons 3) clients can register to recieve packets that are punted for a given reason to be sent to the desired node. 4) nodes which punt packets fill in the {reason,protocol} of the buffere (in the meta-data) and send to the new node "punt-dispatch" 5) punt-dispatch sends packets to the registered nodes or drops Change-Id: Ia4f144337f1387cbe585b4f375d0842aefffcde5 Signed-off-by: Neale Ranns <nranns@cisco.com>
2019-03-13Move the punt/drop nodes into vlibNeale Ranns1-0/+4
The core VLIB library now has a means to dispoe of buffers. the vlib punt/drop node counts node errors. the vnet punt/drop node counts interface errors. speed up both nodes with the usual reciepe. before: error-drop 8.33e1 after: drop 4.51e1 error-drop 6.81e0 Change-Id: If2e919458a3f2e9d71dbf9c6f1352dafb186a05b Signed-off-by: Neale Ranns <nranns@cisco.com>

2018-12-19vlib: support Hyper-v/Azure VMBusStephen Hemminger1-1/+20
This patch adds support for VMBus to the VPP infrastructure. Since the only device that matters is the netvsc Poll Mode Driver in DPDK, the infrastructure is much simpler than PCI. Change-Id: Ie96c897ad9c426716c2398e4528688ce2217419b Signed-off-by: Stephen Hemminger <stephen@networkplumber.org>
