The patch uses one string buffer that collects all the packet dump output into this buffer and then printouts it at last, that guarantees to printout separately the dump output per packet. Fixes: d862c45 ("app/testpmd: move dumping packets to a separate function") Signed-off-by: Jiawei Wang <jiaweiw@nvidia.com> Acked-by: Viacheslav Ovsiienko <viacheslavo@nvidia.com> --- v4: * Remove 'break' the loop if trancation and contiue to handle next packet. v3: * Use the marco instead of function calls to simplfy code. * Use the shorter chars '...' append into the dump to notify the truncation. * Update the commit message. * Rebase. v2: * Print dump output of per packet instead of per burst. * Add the checking for return value of 'snprintf' and exit if required size exceed the print buffer size. * Update the log messages. --- app/test-pmd/util.c | 176 ++++++++++++++++++++++++++++++++++------------------ 1 file changed, 116 insertions(+), 60 deletions(-) diff --git a/app/test-pmd/util.c b/app/test-pmd/util.c index 649bf8f..fc7edf1 100644 --- a/app/test-pmd/util.c +++ b/app/test-pmd/util.c @@ -15,12 +15,23 @@ #include "testpmd.h" +#define MAX_STRING_LEN 8192 + +#define MKDUMPSTR(buf, buf_size, cur_len, ...) \ +do { \ + if (cur_len >= buf_size) \ + break; \ + cur_len += snprintf(buf + cur_len, buf_size - cur_len, __VA_ARGS__); \ +} while (0) + static inline void -print_ether_addr(const char *what, const struct rte_ether_addr *eth_addr) +print_ether_addr(const char *what, const struct rte_ether_addr *eth_addr, + char print_buf[], int buf_size, int *cur_len) { char buf[RTE_ETHER_ADDR_FMT_SIZE]; + rte_ether_format_addr(buf, RTE_ETHER_ADDR_FMT_SIZE, eth_addr); - printf("%s%s", what, buf); + MKDUMPSTR(print_buf, buf_size, *cur_len, "%s%s", what, buf); } static inline bool @@ -74,13 +85,16 @@ uint32_t vx_vni; const char *reason; int dynf_index; + int buf_size = MAX_STRING_LEN; + char print_buf[buf_size]; + int cur_len = 0; + memset(print_buf, 0, sizeof(print_buf)); if (!nb_pkts) return; - printf("port %u/queue %u: %s %u packets\n", - port_id, queue, - is_rx ?
