This patch will hide timer data of offline cpus. The original output is like below: <cut> crash> timer ... 4310933504 ffffffffa0311750 ffffffff8154f790 <inet_frag_secret_rebuild> 4380688384 ffff880036dae568 ffffffff8157ed30 <ipv6_regen_rndid> TVEC_BASES[2]: ffff88003db20000 JIFFIES 4310640297 EXPIRES TIMER_LIST FUNCTION TVEC_BASES[3]: ffff88003db44000 JIFFIES 4310640297 ... <cut>
With data of offline cpu(cpu #2) hiden, the output is like below: <cut> crash> timer ... 4310933504 ffffffffa0311750 ffffffff8154f790 <inet_frag_secret_rebuild> 4380688384 ffff880036dae568 ffffffff8157ed30 <ipv6_regen_rndid> TVEC_BASES[2]: <OFFLINE> TVEC_BASES[3]: ffff88003db44000 JIFFIES 4310640297 ... <cut> Signed-off-by: Qiao Nuohan <[email protected]> --- kernel.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/kernel.c b/kernel.c index 0665ada..6da669e 100755 --- a/kernel.c +++ b/kernel.c @@ -7435,6 +7435,16 @@ dump_timer_data_tvec_bases_v2(void) cpu = 0; next_cpu: + /* + * hide data of offline cpu and goto next cpu + */ + + if (hide_offline_cpu(cpu)) { + fprintf(fp, "TVEC_BASES[%d]: <OFFLINE>\n", cpu); + if (++cpu < kt->cpus) + goto next_cpu; + } + count = 0; td = (struct timer_data *)NULL; -- 1.8.5.3 -- Crash-utility mailing list [email protected] https://www.redhat.com/mailman/listinfo/crash-utility
