v2 updates: - Includes DPIF command switching at runtime - Includes AVX512 DPIF implementation - Includes some partially related changes (can be split out of set?) --- netdev output action optimization --- avx512 dpcls 16-block support optimization
Hi OVS Community, This patchset is a v2 for making the DPIF component of the userspace datapath more flexible. The same approach as has been previously used for DPCLS is used here, where a function pointer allows selection of an implementation at runtime. The flexibility from the above changes enables ISA optimized implementations of the DPIF component of the datapath. As these ISA optimized implementations also require access to EMC/SMC/HWOL features, these have been split out to seperate header files. The file splitting also improves maintainability, as dpif_netdev.c has ~9000 LOC, and very hard to modify due to many structs defined locally in the .c file, ruling out re-usability in other .c files. Questions welcomed!
