Hi Everyone, I have a co-worker who wants to use our Kernel CI & Lava Virtual Machine. He says he wants to boot the VM, log in, and run a command that downloads a kernel and then tests multiple defconfig's and multiple versions of the Linux kernel. What is the best tool to do this (lava-ci, lava-tool, or a different tool)? Can you point me to some examples of the tool you recommend? Any help you can offer would be greatly appreciated. -- Don Brown Codethink, Ltd. Software Engineering Consultant Indianapolis, IN USA Email: don.brown(a)codethink.co.uk Mobile: +1 317-560-0513

One time out per test issue

by Denis HUMEAU

Hello, I'm trying to set one timeout per test in a job. To do so I'm declaring one test block per test. Unfortunately, it seems that only the first timeout declaration is taken into account. Did I miss something in my job definition? Best regards, Denis

Package installation from Lava job

Dear all, This is my first post on the mailing list, I hope I'm at the right place. Using Lava V2, I'm trying to install packages in the DUT following the guidelines from https://validation.linaro.org/static/docs/v2/writing-tests.html#test-defini… My job looks like this: metadata: (...) install: sources: - http://<local_network_package_server>/sti - http:// <local_network_package_server>/all - http:// <local_network_package_server>/cortexa9hf-neon deps: - python-pytest - python-lxml - packagegroup-core-buildessential* run: steps: - step1 - step2 parse: pattern: "^(?P<test_case_id>\\w+) RESULT:(?P<result>(pass|fail|unknown))" fixupdict: FAILED: fail SUCCESS: pass ABORTED: unknown Running this test, I get the following error: <LAVA_TEST_RUNNER>: started<LAVA_TEST_RUNNER>: looking for work in /lava-3715/0/lava-test-runner.conf-1484266027 <LAVA_TEST_RUNNER>: running 0_TC_BENCH_DISK_AIO_STRESS under lava-test-shell... <LAVA_TEST_RUNNER>: running 0_TC_BENCH_DISK_AIO_STRESS installer ... /lava-3715/0/tests/0_TC_BENCH_DISK_AIO_STRESS/install.sh: line 5: lava-add-sources: command not found /lava-3715/0/tests/0_TC_BENCH_DISK_AIO_STRESS/install.sh: line 6: lava-add-sources: command not found /lava-3715/0/tests/0_TC_BENCH_DISK_AIO_STRESS/install.sh: line 7: lava-add-sources: command not found Error: OPKG package manager not found in the path.

Now i am trying to add the BBB device on lava. > 4.

Re: [Lava-users] Booting x86 device via TFTP and iPXE

I have amd64 machine with UEFI. "stuck" ? This is a standard amd64 Debian kernel with modules and initramfs. It is already UEFI-aware. Does the machine run Debian natively?

Yes, however, to debug what is going on, you should switch to known working files so that you have a valid comparison with known working test jobs. Once debugging has produced some results, then switch back to the locally built kernels. Change one thing at a time. >> That just isn't going to work.

Your original email quoted: context: extra_kernel_args: initrd=/rootfs.cpio.gz root=/dev/ram0 rootfs.cpio.gz does not exist when the machine boots. The initramfs will have been downloaded by TFTP and loaded directly into memory, it simply does not exist as a cpio.gz any longer. /dev/ram0 shouldn't be needed with modern kernels. At best, it would seem that these options are ignored. Debian initramfs log: Begin: Loading essential drivers ... done. Begin: Running /scripts/init-premount ... done.

Matched prompt #5: $initramfs$ > This boot option have been detected before effort to automate the process with LAVA. Without it we could see kernel panic. With it we successfully load kernel and rootfs (from Buildroot). May be in Linaro you embed that boot options in compile time? No, we do not embed anything in V2 (it's one of the key changes from V1, we don't hid magic like that anymore.) The files were prepared with: https://git.linaro.org/lava-team/refactoring.git/tree/scripts/x86_64-nfs.sh You can also see the build log for the original Debian kernel package if relevant. https://tracker.debian.org/pkg/linux-signed https://buildd.debian.org/status/fetch.php?pkg=linux-signed&arch=amd64&ver=… Running x86_64-nfs.sh in an empty directory will provide access to the config of the kernel itself as well as the initramfs and supporting tools. It's possible these context arguments are hiding some other problem in the kernel but, as described so far, the options seem to make no sense. The command line used in our tests is simply: Command line: ip=dhcp console=ttyS0,115200n8 lava_mac={LAVA_MAC} (where LAVA_MAC does not need to be defined for these devices.) -- Neil Williams ============= neil.williams(a)linaro.org http://www.linux.codehelp.co.uk/

Network config issue on pandaboard in LAVA V2

by Lisa Nguyen

Hi, I'm learning to create a job to boot a mainline kernel on the pandaboard with debian rootfs in LAVA V2, but I keep running into these network related errors: https://staging.validation.linaro.org/scheduler/job/168134#L625 https://staging.validation.linaro.org/scheduler/job/168134#L642 Here's my job definition: https://staging.validation.linaro.org/scheduler/job/168134/definition Am I missing something to get the network working? I'd like to be able to run basic smoke tests as a start. Regards, Lisa

$HOME not set on LXC machine

by Rafael Gago Castano

Hello. I'm trying to start LXC Debian hacking sessions on our V2 LAVA server. This is the related configuration: http://pastebin.com/index/DNGpJfc6 And I'm mostly doing what's in here: https://git.linaro.org/lava-team/hacking-session.git The problem I'm facing is that inside a script the environment seems to be broken, so there is no way to copy to ~/.ssh. Regarding the environment I get this output: $ echo $HOME $ echo $USER $ cat /etc/passwd | grep root root:x:0:0:root:/root:/bin/bash $ ls -al /root total 16 drwx------ 2 root root 4096 Dec 16 15:33 . drwxrwxrwx 19 root root 4096 Dec 23 13:18 .. -rw-r--r-- 1 root root 570 Jan 31 2010 .bashrc -rw-r--r-- 1 root root 148 Aug 17 2015 .profile $ env TESTRUN_ID=1_hacksession-debian SHLVL=4 OLDPWD=/ container=lxc _=defs/hacksession-debian/setup_session COLUMNS=80 PATH=/lava-248/1/../bin:/usr/local/bin:/usr/local/sbin:/bin:/usr/bin:/usr/sbin:/sbin LAVA_RESULT_DIR=/lava-248/1/results/1_hacksession-debian-1482499502 LANG=C LC_ALL=C.UTF-8 PWD=/lava-248/1/tests/1_hacksession-debian LINES=24 If I mimic the lava LXC machine creation commands (lxc-create) and I attach to the machine I get a sane environment. Is this expected behavior? BR, Rafael Gago
