LTP result

Introduction

Linux Test Project (LTP) is an open source project with a goal to deliver test suites to the open source community that validate the reliability, robustness, and stability of Linux. (http://ltp.sourceforge.net)

Unlike typical desktop/server distributions, embedded linux distribution is highly customized for a specific purpose. It's not unusual to observe more failures in Yocto than in a typical desktop Linux distro like Ubuntu, etc. So the major purposes of this work are:

• to understand the reasons for existing LTP failures. If the cause is from a specific package itself, go to fix it. Or else if the error simply come from the fact that a given package doesn't exist in current profile, add the explanation here
• to track LTP test results cross Yocto releases, and ensure a declining error number for same profile
• to be the reference if Yocto users want to get a base picture

Overall matrix

Overall matrix tends to track the change of LTP test results along with Yocto's progress.

For each LTP failure, we define below status:

• Not start: not start investigation yet
• Pending: in investigation
• LTP: fail on other distribution too
• Fixed: fixed, which is expected to disappear in next milestone (bug link may be attached in comment)
• Not A Bug: if the failure is simply caused by missing some packages in current profile (the alternative profile may be listed in the comment if it works)

In below table we list total LTP failures for each architectures in each milestone, with the number in parenthesis indicating "Native"/"Fixed"/"Not A Bug number". All log files on a machine is compressed and linked here too. This way the owner of each machine is able to update the column independently.

Milestone	qemux86	qemuppc	qemuarm	qemumips	atom-pc
1.0-M2	36(0/0/0)	n/a	n/a	n/a	n/a

Below table includes which LTP categories are included in the measurement:
