OpenDataPlane (1.41.1.0)
Backward compatible API changes
DMA
- Add
odp_dma_compl_user_area()
function which returns pointer to the user area configured with DMA completion event pool parameters. - Clarify that DMA session names don't need to be unique.
Event
- Add
odp_event_user_area()
function which returns a pointer to the user area associated with the event.
Init
- Add
odp_term_abnormal()
function that can be used to abnormally terminate an ODP application after a non-recoverable error. Depending on the implementation, this function may attempt to dump stack and other memory areas, clean up and stop HW operations and/or perform other actions helpful in postmortem analysis.
Packet
- Extend packet transmit completion (
odp_packet_tx_compl_request()
) with poll mode. When enabled, packet transmit completion status can be checked withodp_packet_tx_compl_done()
. - Add
odp_packet_free_ctrl_set()
function for controlling packet output interface to not free a packet after transmitting it. - Add
odp_packet_free_ctrl()
function for reading packet's free control option value.
Pool
- Relax
odp_pool_stats()
specification to allow implementations to have some delay until pool statistics are updated. - Add new function
odp_pool_stats_selected()
for reading only selected pool statistic(s).
Timer
- Split
odp_timer_cancel()
failure reason into timing related and other failures. - Rename
odp_timer_set_t
toodp_timer_retval_t
as it is used now for start, restart, and cancel operations.odp_timer_set_t
remains as a typedef for backward compatibility. - Add
odp_timer_sample_ticks()
function that samples tick value of multiple timer pools simultaneously. - Allow implementation to place the first timer as close as it can to one period when starting a periodic timer with
first_tick
set to 0. - Clarify that periodic timer base frequency uses fractional numbers the same way as timer tick info (
odp_timer_tick_info_t
). Integer part specifies full hertz and fractional part specifies parts of a hertz. - Clarify that
odp_timer_periodic_capability()
call does not overwrite the base frequency value when 1 is returned. - Clarify that some implementations may support only certain periodic timer base frequencies and those depend on source clock frequency.
Performance Tests
bench_timer
- Add new test application for measuring call latency of small functions in the timer API.
dma_perf
- Refactor DMA test application to support multiple worker threads. The number of in-flight transfers can be configured and workers will always try to keep that many transfers active through single or per-worker DMA session.
ipsecfwd
- Add support for running the application in process mode.
