2022-08-25vlib: introduce DMA infrastructureMarvin Liu1-0/+2
This patch introduces DMA infrastructure into vlib. This is well known that large amount of memory movements will drain core resource. Nowadays more and more hardware accelerators were designed out for freeing core from this burden. Meanwhile some restrictions still remained when utilizing hardware accelerators, e.g. cross numa throughput will have a significant drop compared to same node. Normally the number of hardware accelerator instances will less than cores number, not to mention that applications number will even beyond the number of cores. Some hardware may support share virtual address with cores, while others are not. Here we introduce new DMA infrastructure which can fulfill the requirements of vpp applications like session and memif and in the meantime dealing with hardware limitations. Here is some design backgrounds: Backend is the abstract of resource which allocated from DMA device and can do some basic operations like configuration, DMA copy and result query. Config is the abstract of application DMA requirement. Application need to request an unique config index from DMA infrastructure. This unique config index is associated with backend resource. Two options cpu fallback and barrier before last can be specified in config. DMA transfer will be performed by CPU when backend is busy if cpu fallback option is enabled. DMA transfer callback will be in order if barrier before last option is enabled. We constructs all the stuffs that DMA transfer request needed into DMA batch. It contains the pattern of DMA descriptors and function pointers for submission and callback. One DMA transfer request need multiple times batch update and one time batch submission. DMA backends will assigned to config's workers threads equally. Lock will be used for thread-safety if same backends assigned to multiple threads. Backend node will check all the pending requests in worker thread and do callback with the pointer of DMA batch if transfer completed. Application can utilize cookie in DMA batch for selves usage.

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.

2020-04-13buffers: 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.
