Re: s390 user_enable_single_step() (Was: odd utrace testing results on s390x)

2010-01-06 Thread caiqian

 Cai, any chance you can help? Using /usr/bin/console I can't choose
 anotherkernel at the 00: Please choose (default will boot in 15 seconds):
 stage, how can I do this???

As Heiko mentioned, I did manage to enter,

#cp vi vmsg 2

during the prompt to get to the second kernel to boot...

Thanks,
CAI Qian



Re: [PATCH 0/7] utrace/ptrace

2009-12-29 Thread caiqian

 This is the new iteration of Roland's utrace patch, this time
 with rewrite-ptrace-via-utrace + cleanups in utrace core.

Tested-by: CAI Qian caiq...@redhat.com



Re: odd utrace testing results on s390x

2009-12-24 Thread caiqian

 Could you please re-test with this patch applied?

It turned out that this patch did not make much difference. the step-simple is 
still failing with the patch applied. It could be reproduced a few times after 
a fresh reboot. The test exited with 1 here,

  /* Known bug in 2.6.28-rc7 + utrace patch:
   * child was left to run freely, and exited
   * Deterministic (happens even with NUM_SINGLESTEPS = 1)
   */
  if (WIFEXITED (status))
{
  VERBOSE(PTRACE_SINGLESTEP did not stop (step #%d)\n, i+1);
  assert (WEXITSTATUS (status) == 42);
  exit (1);
}

Here was the strace output when failure.

Re: new Fedora 13 utrace kernel

Hi Roland,

The utrace patch looks suspicious in utrace.h, which cause the compilation 
failure without CONFIG_UTRACE. I have confirmed that the git tree looks sane.

Re: powerpc: step-jump-cont failure (Was: [PATCH] utrace: don't set -ops = utrace_detached_ops lockless)

2009-12-07 Thread caiqian

 I'll try to investigate, but currently I am all confused, and I
 suspect we have some user-space issues. If only I knew something about ppc...

Sorry for the confusing.

 
 Ananth, could you please confirm once again that step-jump-cont (from
 ptrace-tests testsuite) not fail on your machine? If yes, please tell
 me the version of glibc/gcc. Is PTRACE_GETREGS defined on your
 machine?

Funny enough. The above failure only seen on that particular system so far. In 
fact, different PPC64 systems have different results there (roland's git tree + 
your lockless patch).

Looks like failed only for syscall-reset and step-fork, as we have discussed

 Yes, it looks good so far. Ptrace tests also does not show any
 regression.

I said this too early. Looks like step-jump-count started to fail now.

Hello!

Please find below results by using the latest ptrace testsuite with and without

were getting less with the ptrace-utrace patchset applied. There are some tests 
failed for both kernels.

GDB Testsuite Results with CONFIG_UTRACE

2009-11-24 Thread caiqian
Hello!

The test was conducted on linux-2.6-utrace utrace-ptrace branch with and 
without CONFIG_UTRACE.
The machine was an Intel x86_64 system. Biarch and other testing are under way. 
Here is the diff, and the results look similar. Detailed logs can be found at,
http://people.redhat.com/~qcai/{noutrace,utrace}/

utrace tests

2009-11-09 Thread caiqian
Hello!

Sorry for the cross-posting. Wondering if there are some existing utrace tests 
that can be used for regression testing. There is a ntrace tests under,
http://people.redhat.com/roland/utrace/old/

Are those tests still relevant?

Thanks!
CAI Qian
