Feature request:
Please add an option to "lava-server manage device-types" to add an
alias. Currently this can be done from the django interface, but the
command-line interface is much more automation friendly and
administrator friendly.
Thanks,
Kevin
Hi , we're attempting to use lava-ci to submit a test to lava, I've
cloned it from
https://github.com/kernelci/lava-ci.git
But when I attempt to submit a simple test
../lava-job-runner.py --username lavauser --token ... --server http://localhost:8080/RPC2
I get
Connecting to Server...
Connection Successful!
connect-to-server : pass
Gathering Devices...
Gathered Devices Successfully!
Gathering Device Types...
Gathered Device Types Successfully!
Submitting Jobs to Server...
but I don't see any submitted jobs in the lava2 web interface, is there
anything obvious elsewhere I should be checking? - or does the absence
of a 'Submitted Jobs successfully', if there should be one, means nothing
has been submitted?

Hi,
In LAVA v1, one could declare login commands to be run after logging in and
before starting any of the tests. For example:
"actions": [
{
"command": "deploy_image",
"parameters": {
"image": "https://some-url-to-a-rootfs.ext4.img.gz",
"bootfstype": "ext2",
"login_commands": [
"sudo su"
],
"login_prompt": "login:",
"username": "username",
"password_prompt": "Password:",
"password": "password"
}
},
In this case, "sudo su" is needed to open a regular user session and inherit
the user's environment while also having root privileges.
In LAVA v2, there isn't the possibility to do anything like this directly. One
could define a test with inline commands, but this is not ideal. The login
commands are not a test but part of how the job sets up the environment in
which the tests are run - i.e. it's part of the initial conditions. Also it's
quite a convoluted and lengthy way of running some commands, and it relies on
the side effects of that "login commands test" to persist when running
subsequent tests.
So I've made a couple of patches to see how this could be implemented in LAVA
v2 with an extra parameter in auto_login:
https://review.linaro.org/#/q/topic:T5703-login-commands
For example:
- boot:
method: qemu
auto_login:
login_prompt: 'login:'
username: user
password_prompt: 'Password:'
password: password
login_commands:
- sudo su
Essentially, this makes auto_login more flexible. At the moment, after logging
in auto_login sets the shell prompt: this is already some kind of hard-coded
login command. Some jobs need to run other things such as "sudo su" to stick
to the same example.
Another login command we've used is "systemctl --failed" to show if any systemd
units (services) failed to load during boot.
Notes from the Gerrit reviews:
* The login commands can't be part of a device definition as they are not
related to the device hardware or the boot configuration. For example, when
running Android, one would not want to run "sudo su" but maybe "setprop ..."
or something else - to be defined in each job.
* The login commands should not be fixed in a given distro / userspace
configuration as each job may need to set up a different initial environment.
For example, some jobs may need to be run with a regular user and would not
use the "sudo su" login command.
* Some documentation and unit tests would need to be added for this to be
merged. This is to first discuss the idea and review the code changes.
Any thoughts? Would it make sense to add this feature or maybe implement it
differently?
Best wishes,
Guillaume
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.

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
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

It seems lava-add-sources is not copied to the target. Do I understand the log correctly?

Hello Team,
My name is guru. i am very new to lava and i am very much interested using

"stuck" ? This is a standard amd64 Debian kernel with modules and
initramfs. It is already UEFI-aware. Does the machine run Debian
natively? Is there a Debian kernel you can use in your LAVA
submissions (with modules and ramdisk)?

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.

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.

> 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-signedhttps://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.)
