Building Embedded Debian-based system images

by Zoran S

Hello to Linaro developers, Recently I have learned that Linaro has developed its own tool to build Embedded Debian-based system images. I am very interested in this work/this tool. So I have some questions regarding this domain. [1] Do you have published this tool on the Open Source? [2] If YES, what are the web pointers to it, and the docs I can read and get familiar with the process? [3] Does it include scripts to enhance initramfs (the technology Linaro uses to do that), and where are the locations to read about it? [4] You name it (if I miss something, please, feel free to fill the gaps)! I use (almost always) YOCTO based build tool to create initramfses to test upon them (you know this already if you read my recent emails to this list). But I would like to have alternative method, and Linaro tool seems excellent one as alternative, for many reasons. Thank you in advance, Zoran Stojsavljevic _______

Why the lava is not designed a machnism that notify user when only a test case is complete(err..)

by john zhang

Lava xml-rpc notification machnism, criteria.status indicates which event can be notified to user (by hook callback). But the criteria.status only has such as "Complete Incomplete,Canceled,finished" events. Why the lava is not designed a machnism that notify user when only a test case is complete(err..),if so that user has more rights to control test process execution.

Is the use of multinode that a single test job's all test cases are parallel executed simultaneously on multiple devices?

by chao yang

https://validation.linaro.org/static/docs/v2/glossary.html#term-multinode https://validation.linaro.org/static/docs/v2/multinode.html it said "A single test job which runs across multiple devices". I still don't quite understandt the purpose of MultiNode. Is that mean that a single test job's all test cases are parallel executed simultaneously on multiple devices? For example it have 10 test cases and 5 devices, when job is running, firstly the former 5 cases is distributed to 5 devices and parallel run (case 1 is run on device 1,case 2 is run on device 2,... device 5 is run on device 5). When a case is end(suppose case 2) ,then case 6 is scheduled to run on device 2... and so on.Is my understanding correct?

xmlrpc mechanism to monitor job error

by john zhang

I want to implement a function: When a test case in job is crush or return err(no zero), the job can be rescheduled(or resubmit). Does it need to write own event notification? Need monitor "job Incomplete" action? In addition, according to lava xmlrpc doc, I input command in lava server console: python zmq_client.py -j 121 --hostname tcp://127.0.0.1:5500 -t 1200 .The was error : .... File "/usr/lib/python2.7/httplib.py", line 821, in connect self.timeout, self.source_address) File "/usr/lib/python2.7/socket.py", line 557, in create_connection for res in getaddrinfo(host, port, 0, SOCK_STREAM):

Boot time measurement with Lava

by Denis HUMEAU

Hello Lava users, Do you have any example or advice to share on a way to measure boot time using Lava? Let's say that I use u-boot, a minimal boot for a device running Linux, and I want to measure the time spent between Power On (pdu-reboot e.g) and Linux prompt. Best regards, Denis
