PATCH 1/1 Integration of MCE test suite into LTP

Hi Huang Ying,

Quoted 8 lines · Huang Ying

Hi, All,

We are working on a test suite to test the Linux kernel MCE handling logic named mce-test, which can be find at:
git://git.kernel.org/pub/scm/utils/cpu/mce/mce-test.git. There is a HOWTO for it, which is attached with the mail.

Quoted 8 lines

We think the testing target of mce-test is part of that of LTP, so it is better to integrate mce-test into LTP. Do you think so?

As for integration scheme, maybe we can first add mce-test into LTP as a separate test case, just as kdump test case. What's your opinions?

Any comment is welcome!

Sorry for the very late response to your proposal. Please find below the first patch which will integrate the existing mce-test to LTP. I had just done a sanity checking of building it. The following patch will still need:

1) Exclusive testing and sharing those results with the LTP community,
2) Comments for and rewriting of this patch for coding styles,
3) Sign off from Huang Ying <[email protected]>, or, the concerned Authors,

+To verify the result of MCE testing, the MCE record from kernel (via

+  BANK NUMBER
+  TSC NUMBER
+  RIP NUMBER
+  ADDR NUMBER
+  MISC NUMBER
+  STATUS NUMBER
+  MCGSTATUS NUMBER
+
+  Multiple MCE records are separated by one empty line.
+
+- Enhance mce-inject or develop a new tool to convert from other
+  format to standard format.
+

Hi Huang Ying,

Hi, All,

We are working on a test suite to test the Linux kernel MCE handling logic named mce-test, which can be find at:
git://git.kernel.org/pub/scm/utils/cpu/mce/mce-test.git. There is a HOWTO for it, which is attached with the mail.

We think the testing target of mce-test is part of that of LTP, so it is better to integrate mce-test into LTP. Do you think so?

As for integration scheme, maybe we can first add mce-test into LTP as a separate test case, just as kdump test case. What's your opinions?

Quoted 8 lines
Quoted 2 lines

Any comment is welcome!

Sorry for the very late response to your proposal. Please find below the first patch which will integrate the existing mce-test to LTP. I had just done a sanity checking of building it. The following patch will still need:

1) Exclusive testing and sharing those results with the LTP community,

My initial first tests results are:

Please also find the results attached.

Some inconsistencies:
1) GCOV is already built in the booted kernel, still the error message,
2) Absence of /sys/devices/system/machinecheck/ though the kernel .config suggests that:
CONFIG_X86_MCE=y
# CONFIG_X86_MCE_NONFATAL is not set CONFIG_X86_MCE_P4THERMAL=y

Is there something i am missing in the setup ?

Can you please then provide this information inside mce-test/README, so that users are exactly aware of:

1. Which kernel to pick up,
2. Which additional patches to apply,
3. Which config options to set,

before building and running these tests.

Once mainline stable releases are through, you can then again update mce-test/README with similar information.

I would like people to start doing some testing with your present mce-test as well. As suggested by Andi, please drop in:

1. a minimal patch which adds the tests(you want) to LTP,
2. update mce-test/README in the same patch with all the above info,
3. attach test results against the patches you have dropped to ltp,

I would prefer no wide scale reformattings for now, that will impact any out of tree patches other people have and the benefits would seem to be small.

The code is probably not fully compliant, but should be close enough to kernel style (after all it was written by experienced kernel developers)

+To verify the result of MCE testing, the MCE record from kernel (via

+MCE record (for software inject error: the input MCE record). To
+compare MCE record, the following scheme is proposed:
+
+- Define a standard MCE record representation format. It should be
+  human readable, compatible with MCE parser in mce-inject, easy to
+  manipulate in shell (such as remove a field), easy to compare
+  (literally).
+
+  One MCE record is as follow:
+
+  CPU NUMBER
+  BANK NUMBER
+  TSC NUMBER
+  RIP NUMBER
+  ADDR NUMBER
+  MISC NUMBER
+  STATUS NUMBER
+  MCGSTATUS NUMBER
+
+  Multiple MCE records are separated by one empty line.
+
+- Enhance mce-inject or develop a new tool to convert from other
+  format to standard format.
+
+- Develop a new tool based on /usr/sbin/mcelog to output mce-inject
+  compatible MCE record. Because there may be different (uncompatible
+  version) /usr/sbin/mcelog on different machine.
+
+- During verifying, firstly convert various MCE recoards from kernel
+  and reference MCE records to standard format, then compare the
+  standard format MCE records in shell.

Thanks for merging.

FYI -- there's already one change. The value of the MADV_POISON injection interface has changed in linux-next (12->100). That's fixed in the git tree now.

Hi, All,

We are working on a test suite to test the Linux kernel MCE handling logic named mce-test, which can be find at:
git://git.kernel.org/pub/scm/utils/cpu/mce/mce-test.git. There is a HOWTO for it, which is attached with the mail.

We think the testing target of mce-test is part of that of LTP, so it is better to integrate mce-test into LTP. Do you think so?

As for integration scheme, maybe we can first add mce-test into LTP as a separate test case, just as kdump test case. What's your opinions?

Quoted 8 lines
Quoted 2 lines

Any comment is welcome!

Sorry for the very late response to your proposal. Please find below the first patch which will integrate the existing mce-test to LTP. I had just done a sanity checking of building it. The following patch will still need:

1) Exclusive testing and sharing those results with the LTP community,

My initial first tests results are:

Quoted 9 lines
Quoted 3 lines
# uname -a
Linux x206f 2.6.29-gcov #1 SMP Fri Jun 19 12:14:27 IST 2009 i686 i686
i386 GNU/Linux

mce-test needs at least Linux kernel 2.6.31-rc? and some additional injection related patches from:
http://ftp.kernel.org/pub/linux/kernel/people/yhuang/mce/. We are working on pushing these additional patches into 2.6.32.

Can you please then provide this information inside mce-test/README, so that users are exactly aware of:

1. Which kernel to pick up,
2. Which additional patches to apply,
3. Which config options to set,

Quoted 5 lines
Quoted 1 line

before building and running these tests.

I have add these information into the HOWTO in mce-test/doc/howto.txt. In README, there is a "pointer" to howto.txt in section test instruction. Is it OK for you?

Yes, this should be fine.

Quoted 5 lines
Quoted 3 lines

Once mainline stable releases are through, you can then again update mce-test/README with similar information.

OK. I will update the document after upstream merging.

Great.

Quoted 9 lines
Quoted 8 lines

I would like people to start doing some testing with your present mce-test as well. As suggested by Andi, please drop in:

1. a minimal patch which adds the tests(you want) to LTP,
2. update mce-test/README in the same patch with all the above info,
3. attach test results against the patches you have dropped to ltp,

Quoted 4 lines

OK. I will do this.

I will check the coding style with checkpatch.pl. Do you have other comments about the code?

Nothing as of now. Will wait for your first minimal patch in LTP.

Subrata

Thank you too.

(wrote also some early code)

One thing I should add. There's still development going on for enhancing mce-test (e.g. adding stress tests and increasing coverage). Right now I would expect the kernel.org git repository to be still the primary repository where development is done, with occasional code drops into LTP. I hope that's ok for you.

Sure. It should be absolutely fine. Wheneven you want to add/update, just drop in a patch with the set of new results the patch would have generated.

Quoted 3 lines

It would be good if you could feed any patches on the LTP side for mce-test through Ying also.

As always welcome. Anybody can send patches anytime ;-)

No. we started to follow the Linux Kernel coding style as rectified everytime by scripts/checkpatch.pl.
