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
(current data is an example taken from 12/11 nightly test, which will be updated after M2 test is finished)
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(2/11/0), file="LTP-M2-qemux86.tar.gz" log files | n/a | n/a | n/a | n/a |
Below table includes which LTP categories are included in the measurement:

Current Milestone (1.0-M2)
(current data is an example taken from 12/11 nightly test, which will be updated after M2 test is finished)
This show details info about each failure in a milestone, merged from the results from all machines:
