In this situation, this function should further -continue preparing map for other online lcores instead of returning with -1 -for a first unavailable lcore. - -Also, in SMT=off scenario for powerpc, lcore ids can not be always indexed from -0 upto 'number of cores present' (/sys/devices/system/cpu/present). For eg, for -an online lcore 32, core_id returned in sysfs is 112 where online lcores are -10 (as in one configuration), hence sysfs lcore id can not be checked with -indexing lcore number before positioning lcore map array. - -Signed-off-by: Gowrishankar Muthukrishnan -Acked-by: Chao Zhu -Acked-by: Cristian Dumitrescu - -Origin: Upstream, commit:58d55fd279dc6f8f8d92fcab3362e24e19c9fbea -Author: Gowrishankar Muthukrishnan -Last-Update: 2016-09-21 ---- - examples/ip_pipeline/cpu_core_map.c | 8 ++++++++ - 1 file changed, 8 insertions(+) - -diff --git a/examples/ip_pipeline/cpu_core_map.c b/examples/ip_pipeline/cpu_core_map.c -index cb088b1..dd8f678 100644 ---- a/examples/ip_pipeline/cpu_core_map.c -+++ b/examples/ip_pipeline/cpu_core_map.c -@@ -351,8 +351,10 @@ cpu_core_map_compute_linux(struct cpu_core_map *map) - int lcore_socket_id = - cpu_core_map_get_socket_id_linux(lcore_id); - -+#if !defined(RTE_ARCH_PPC_64) - if (lcore_socket_id < 0) - return -1; -+#endif - - if (((uint32_t) lcore_socket_id) == socket_id) - n_detected++; -@@ -368,6 +370,7 @@ cpu_core_map_compute_linux(struct cpu_core_map *map) - cpu_core_map_get_socket_id_linux( - lcore_id); - -+#if !defined(RTE_ARCH_PPC_64) - if (lcore_socket_id < 0) - return -1; - -@@ -377,9 +380,14 @@ cpu_core_map_compute_linux(struct cpu_core_map *map) - - if (lcore_core_id < 0) - return -1; -+#endif - -+#if !defined(RTE_ARCH_PPC_64) - if (((uint32_t) lcore_socket_id == socket_id) && - ((uint32_t) lcore_core_id == core_id)) { -+#else -+ if (((uint32_t) lcore_socket_id == socket_id)) { -+#endif - uint32_t pos = cpu_core_map_pos(map, - socket_id, - core_id_contig, --- -1.9.1 -
