[dpdk-dev] [PATCH v2 0/6] port ioatfwd app to dmadev

[fengchengwen]

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.
