Hi Kevin,
Can you add the following functions?
1. Add dump dmadev which trigger by signal, like:
...
static void
dma_dump(void)
{
uint32_t i, j;
if (copy_mode != COPY_MODE_DMA_NUM)
return;
for (i = 0; i < cfg.nb_ports; i++) {
for (j = 0; j < cfg.ports[i].nb_queues; j++)
rte_dma_dump(cfg.ports[i].dmadev_ids[j], stdout);
}
}
...
static void
signal_handler(int signum)
{
if (signum == SIGINT || signum == SIGTERM) {
printf("\n\nSignal %d received, preparing to exit...\n",
signum);
force_quit = true;
} else if (signum == SIGUSR1) {
dma_dump();
}
}
...
signal(SIGUSR1, signal_handler);
2. Controls the output frequency of print_stats. currently fix 1s, hope could
control by parameters.
Thanks.
