Description shanxifanshi alibaba_cloud_group 2021-12-15 17:01:54 UTC 
[缺陷描述]：
使用iso安装龙芯系统后，无以下内核配置参数：
hardlockup_panic、softlockup_panic、watchdog_thresh、hung_task_timeout_secs、
hung_task_timeout_secs

查询softlockup_panic等内核参数：
[root@localhost ~]# ll  /proc/sys/kernel/hardlockup_panic
ls: cannot access '/proc/sys/kernel/hardlockup_panic': No such file or directory
[root@localhost ~]# ll /proc/sys/kernel/softlockup_panic
ls: cannot access '/proc/sys/kernel/softlockup_panic': No such file or directory
[root@localhost ~]# find / -name 'softlockup_panic'
find: ‘/proc/1300/task/1300/net’: Invalid argument
find: ‘/proc/1300/net’: Invalid argument
[root@localhost ~]# ll /proc/sys/kernel/watchdog_thresh
ls: cannot access '/proc/sys/kernel/watchdog_thresh': No such file or directory
[root@localhost ~]# ll /proc/sys/kernel/hung_task_timeout_secs

内核中softlockup和hardlockup选项
Comment 4 streamlet_hy loongson_group 2021-12-22 10:16:11 UTC 
检测不到是因为目前内核选项默认没有打开。
Comment 5 yangyinglu loongson_group 2021-12-27 11:08:38 UTC 
龙芯最新内核支持softlockup_panic、watchdog_thresh、hung_task_timeout_secs

root@loongson-pc:/home/loongson# ls /proc/sys/kernel/softlockup_panic 
/proc/sys/kernel/softlockup_panic
root@loongson-pc:/home/loongson# ls /proc/sys/kernel/watchdog_thresh 
/proc/sys/kernel/watchdog_thresh
root@loongson-pc:/home/loongson# ls /proc/sys/kernel/hung_task_timeout_secs 
/proc/sys/kernel/hung_task_timeout_secs


hardlockup_panic功能待分析后进行支持

----我在rc2版本看了下，这几个文件还是没有，麻烦再确认下

请使用RC4的内核

---rc4的内核地址，麻烦发一下
Comment 9 HFD loongson_group 2022-01-17 08:57:11 UTC 
rc4内核已经提供，请用新内核测试

---升级到rc4内核验证，该问题仍然未解决

Comment 11 yangyinglu loongson_group 2022-03-24 09:24:33 UTC 
hardlockup_panic 我们暂时不支持，其它的我们再确认一下
Comment 12 yangyinglu loongson_group 2022-03-24 09:39:43 UTC 
其它配置在4.190.190-rc5 合入
