2022-08-30memif: Process bad descriptors correctly in memif_process_descSteven Luong1-10/+35
When there is a bad descriptor, it may in the beginning, in the middle, or at the end of the batch if the batch has more than 3 descriptors. When processing a bad descriptor is encountered in the batch, we need to rollback n_buffers in memif_process_desc(), or the statement in the same function memif_add_copy_op (ptd, mb0 + src_off, bytes_to_copy, dst_off, n_buffers - 1); is wrong because it picks up the wrong buffer_vec_index of the bad descriptor while parsing a good descriptor immediately following the bad descriptor. n_buffers was incremented in the beginning of while (n_left) loop. The other problem is we should count the number of bad packets and reduce ptd->n_packets to get the correct number of packets for subsequent processing in device_input. The last fix is to check if n_buffers == 0 in device_input and skip doing any descriptor copy. This case can happen when all the descriptors are bad in the batch.

2022-08-25vlib: introduce DMA infrastructureMarvin Liu14-0/+1349
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.

2022-08-18nat: Replace port refcounts with simple bitvectorsJon Loeliger2-17/+80
Previously, each address maintained an array of 32-bit reference counts for each of 65K possible ports for each of 4 NAT protocols. Totalling 1MB per address. Wow. A close read of the code shows that an "is used" check precedes each attempted reference count increment. That means the refcount never actually gets above 1. That in turn means algorithmically, a bit vector is sufficient. And one need not be allocated for more than the highest validated port referenced. These changes introduce a dynamically sized bit vector replacing the reference counts, for a maximum of 32K if all 4 protocols use port 65535. In fact, protocol OTHER is never used, so at most 24K will be used, and none of it will be "statically" allocated per address.
