| ooOO_OOoo | iMadper: 壕早 | 02:09 |
| iMadper | ooOO_OOoo: 早. | 02:12 |
| iMadper | ooOO_OOoo: 王老板日子这么滋润? | 02:12 |
| iMadper | ooOO_OOoo: 我还想请教几个ltp的问题呢 | 02:12 |
| ooOO_OOoo | iMadper: 王老板现在niu了呢 | 02:12 |
| iMadper | huntxu: 我 | 02:13 |
| iMadper | huntxu: 修好 | 02:13 |
| iMadper | huntxu: 输入法 | 02:13 |
| iMadper | huntxu: 了 | 02:13 |
| iMadper | ooOO_OOoo: 肯定的啊 | 02:13 |
| iMadper | ooOO_OOoo: 王老板离senior多远? | 02:13 |
| iMadper | ooOO_OOoo: 一年? | 02:13 |
| ooOO_OOoo | ooOO_OOoo: 他说重装了系统，刚把 irc server 发给他了 | 02:13 |
| ooOO_OOoo | iMadper: 估计也快了 | 02:13 |
| iMadper | ooOO_OOoo: 昂. | 02:15 |
| ooOO_OOoo | iMadper: ltp啥问题，王老板还没上线。。 你急的话我问问他 | 02:21 |
| wangli | iMadper | 02:25 |
| ooOO_OOoo | wangli: 王老板早 | 02:25 |
| wangli | 谢老板早 | 02:25 |
| wangli | iMadper, | 02:29 |
| iMadper | wangli: 早 | 02:30 |
| iMadper | wangli: 问一下, 现在systemd情况下, 跑ltp会有很多失败啊 | 02:30 |
| iMadper | wangli: cgroup相关的 | 02:30 |
| wangli | 啥失败 | 02:30 |
| iMadper | wangli: 因为systemd一上来就会按照他需要的拓扑mount很多cgroup的实例 | 02:30 |
| wangli | iMadper, 贴出来看看 | 02:31 |
| iMadper | wangli: 然后ltp的case假设是干净的系统 | 02:31 |
| iMadper | wangli: 好的 | 02:31 |
| iMadper | wangli: https://pastebin.com/B0Znwcu2 | 02:33 |
| MangHuoEr | 对啊 | 02:34 |
| MangHuoEr | 高级了 | 02:34 |
| wangli | iMadper, checking | 02:34 |
| wangli | iMadper, hi, which ltp-version did you run? and what's the kernel-version/arch/platform? | 02:41 |
| iMadper | wangli: LTP Version: 20170516 kernel: modified 4.11 aarch64 | 02:42 |
| wangli | iMadper, it seems not a systemd problem, i guess it is related to cgroup or kernel bug, but still need do some more research | 02:42 |
| iMadper | wangli: So it's not a known bug? | 02:43 |
| wangli | iMadper sorry for input English, my workstation always hung with input Chinese:( | 02:43 |
| iMadper | MangHuoEr: ^^ | 02:43 |
| iMadper | wangli: I was expecting it's a conflict between ltp and systemd. loool | 02:44 |
| wangli | iMadper, not sure, and can you run the latest ltp-20170929 version? | 02:44 |
| iMadper | wangli: any modifications against the cgroup cases? | 02:45 |
| wangli | memcg_stat_test 6 TFAIL: hierarchical_memory_limit is 65536, 131072 expected | 02:45 |
| iMadper | wangli: Yes, because the parent node has a limit of 65536... | 02:46 |
| wangli | iMadper, so you guess the limit set to 65536 in systemd? | 02:47 |
| iMadper | wangli: *nod* | 02:47 |
| wangli | iMadper, sounds reasonable, but we need some more debugging | 02:48 |
| iMadper | wangli: so you never met that issue? | 02:48 |
| wangli | iMadper, i didn't run the cgroup cases before, let me try it now | 02:50 |
| MangHuoEr | cat /sys/fs/cgroup/memory/memory.use_hierarchy ? | 02:50 |
| iMadper | wangli: okay. Shouldn't memcg belong to ktd-team? | 02:51 |
| wangli | iMadper, it's not my working area, but i can do it for you | 02:52 |
| wangli | iMadper, just wait.. | 02:52 |
| iMadper | wangli: thanks tons. | 02:54 |
| kevin125 | 怎么他突然e文了 | 02:59 |
| MangHuoEr | 是的 | 02:59 |
| wangli | iMadper, can you perform 'cat /sys/fs/cgroup/memory/memory.use_hierarchy' as MangHuoEr mentioned above? | 02:59 |
| iMadper | wangli: 1 | 03:00 |
| wangli | iMadper, ok, it's not the hierarchy problem | 03:01 |
| iMadper | wangli: what's the value in your side? | 03:01 |
| wangli | i just noticed that ltp disable it in the cgroup case | 03:01 |
| wangli | echo 0 > memory.use_hierarchy | 03:01 |
| wangli | so it's not related to systemd i think | 03:02 |
| wangli | iMadper, the page_size on your system is? | 03:03 |
| iMadper | wangli: however if it has a sub-node, we can't change the value. | 03:04 |
| iMadper | wangli: and by default, systemd creates sub-nodes. | 03:04 |
| wangli | ========== | 03:05 |
| wangli | testcase_6() | 03:05 |
| wangli | { | 03:05 |
| wangli | echo 0 > memory.use_hierarchy | 03:05 |
| wangli | mkdir subgroup | 03:05 |
| wangli | echo $PAGESIZE > memory.limit_in_bytes | 03:05 |
| wangli | echo $((PAGESIZE*2)) > subgroup/memory.limit_in_bytes | 03:05 |
| ubrl | wangli:. .., 别刷屏，超过6行 大段文字 请贴至paste.ubuntu.com +q 23s | 03:05 |
| wangli | cd subgroup | 03:05 |
| wangli | check_mem_stat "hierarchical_memory_limit" $((PAGESIZE*2)) | 03:05 |
| wangli | cd .. | 03:05 |
| wangli | rmdir subgroup | 03:05 |
| wangli | } | 03:05 |
| wangli | memcg_stat_test 6 TPASS: hierarchical_memory_limit is 8192 as expected | 03:06 |
| iMadper | echo 0 > memory.use_hierarchy <--- this line fails. | 03:06 |
| wangli | iMadper, I get pass on my x86_64 box | 03:06 |
| wangli | iMadper, really? | 03:06 |
| iMadper | do you have a sub-node before executing the test case? | 03:06 |
| iMadper | try to create one before executing it. | 03:07 |
| wangli | i didn't, i just run ltp by default | 03:07 |
| wangli | sure | 03:07 |
| * iMadper brb | 03:10 | |
| wangli | # echo 0 > /dev/memcg/wangli/memory.use_hierarchy | 03:11 |
| wangli | # cat /dev/memcg/wangli/memory.use_hierarchy | 03:11 |
| wangli | 0 | 03:11 |
| wangli | iMadper, ^ | 03:12 |
| iMadper | wangli: so you can still change parent's memory.use_hierarchy? | 03:12 |
| iMadper | wangli: the child node could always be modified. However, in the meanwhile, parent's can't | 03:13 |
| wangli | iMadper, hmm, what kind of situation you hit? I didn't fully understand you mean | 03:15 |
| iMadper | wangli: okay, you have a sub-node "wangli" which located in /dev/memcg/wangli. could you still echo 0/1 > /dev/memcg/memory.use_hierarchy ? | 03:16 |
| iMadper | wangli: What I'm trying to express is: Given a memcg node A. Once A has a child node, The _A_'s use_hierarchy can't be changed. | 03:17 |
| wangli | iMadper, understand | 03:17 |
| wangli | iMadper, i can't modify the parent's too | 03:18 |
| iMadper | wangli: Okay. So by default there is no sub-node inside memcg on rhel7? | 03:20 |
| wangli | iMadper, seems yes! | 03:20 |
| iMadper | wangli: I see. | 03:21 |
| wangli | iMadper, if so, we probably need to modify the ltp-case to cover your system | 03:21 |
| iMadper | wangli: yeah, for ubuntu... | 03:22 |
| iMadper | wangli: it seems the default behavior of ubuntu systemd leads the issue. | 03:23 |
| wangli | iMadper, can you show me the cgroup dir in your system? | 03:24 |
