Subject: itrace: An interrupts tracing tool
Date: Mon, 22 Sep 2014 11:35:43 +0800	[thread overview]
Message-ID: <541F990F.7030806@huawei.com> (raw)

  Many functions depends on interrupts in Linux system, when the interrupts occur an error, it may cause fatal problem.

  Then, we should record their trace when interrupts in and out. The recorded information could help us analyze interrupts errors.

  Itrace is such an interrupts trace tool we have developed, it provides config interface and trace information through "procfs".

  Do you think it has the value to upstream?

  Thanks
  Zhiping Du
