[yocto] using Hob to run images on a custom simulator, other than qemu

Fri Jan 15 04:36:22 PST 2016

Hi Alex, Belen,

Is there some pre-setup necessary in order to run the HOB tests you mentioned?

I did the following:

-          Cloned poky repository, from master: git://git.yoctoproject.org/poky

-          Tried to run a test-case which seems the most related to my changes,  "Case 66 - Run image in Hob." from https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=3478

-          With case 66, at first I was not able to build an image, due to the fact my homedir is on NFS, so I hacked meta/classes/sanity.bbclass, commented out "status.addresult(check_not_nfs(tmpdir, "TMPDIR"))". After that, I was able to build qemu ppc, core-image-minimal, but it took a lot of time, cannot say exactly how much, but for sure it did exceed 8 hours (it was trial and error for me, with disk quota exceeded, deleting to free space and try again). After the image was build, when running the image I get permission errors when running runqemu-ifup (see attached picture), I think it is caused by my homedir being on NFS.

-          With my changes applied on the poky repository, I run again case 66, I found 1 issue which I fixed, and now the behavior is the same. With qemu image I get up to the point with permission errors when running runqemu-ifup, while with my custom image and run script, I can run successfully.

Unfortunately, at this moment I don't have enough quota on a non-NFS location. I can try to work around that, or expect until someone else performs a weekly test run. I am pretty confident now that my changes will not affect the current regression tests.

I would like to get the changes merged into YP 2.1 M2, RC1, which I see has the following schedule:

Release Candidate and Milestone Release schedule (Full Pass QA test follows every RC build)

*             RC1: 1/25/16

*             RC2: 2/1/16

*             M2 release: 2/12/16

Considering the above, how should I proceed next?

Should I log a bug/feature in Bugzilla and submit a patch for it? Do I need some special membership to log bugs and submit patches?

The patch should be on which list/repo? Poky or bitbake (my modified files are in poky\bitbake\lib\bb\ui\crumbs)?

May I rely on some weekly test run, or do I need to work-out my NFS issues?

Thanks for your help,

Mirela

Hi,

Currently there are two test runs that ensure the HOB is functioning correctly, as following:

                - https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=3479

                - https://bugzilla.yoctoproject.org/tr_show_run.cgi?run_id=3478

We also have some of the test cases automated can be run, but as Belen mentioned earlier, HOB is being deprecated so we would have to see if they still run correctly on the latest master. Keep me posted if you want to run them, maybe we can help.

Cheers,

AlexG

These are the test cases I can find in Testopia:

https://bugzilla.yoctoproject.org/tr_list_cases.cgi?searchstr=hob&current_t

ab=case&summary_type=anywordssubstr&summary=hob&field-1-0-0=summary&type-1-

0-0=anywordssubstr&value-1-0-0=hob

Hopefully someone from QA can provide more details on how to run them.

If you want any input on how to present the new options in the UI, let me know. I'll be happy to help.

Cheers

Belén
