by yangjianxiang

Hi lava： Some question about lava V2 2018.11+stretch： 1、 As lava running for weeks，it tasks minutes for the master to schedule jobs to the lava-slave ，and the normal time maybe 20s below. When we restar both lava master and lava slave，it schedule job in 20s again. Can you tell us how to solve the problem，thanks very mutch. [cid:image002.png@01D6F0D5.449B7F70] 2、we want to know how lava code works，can you give us some document. Sometimes we want to modify the lava steps，but we don’t know how to do.

WG: Help with new device integration

by Marcel Trattner

Dear Lava-Team, I contacted you a few weeks ago for some help with the integration of a new device. We got a bit further thanks to you but we're faceing some new issues and we hoped that you could help us with this. We are using the official Docker-Compose<https://git.lavasoftware.org/lava/pkg/docker-compose> repository and specified a new device dictionary on the server container. As a device type we use a newly created device type that extends base-fastboot device-type, which looks like this: {% extends 'rse22.jinja2' %} {% set power_on_command = 'python ./root/power-control/ppson.py' %} {% set power_off_command = 'python ./root/power-control/ppsoff.py' %} {% soft_reboot_command = 'reboot' %} {% hard_reset_command = 'python ./root/power-control/ppsoff.py && sleep 5 && python ./root/power-control/ppson.py' %} {% set connection_list = [uart0] %} {% set connection_commands = {uart0: telnet <ip_host_machine> 7101} %} {% set connection_tags = {uart0: [primary, 'telnet']} %} But with this we received the following error: [cid:image001.png@01D6EE7C.31C35A90] The error disappeared however when we removed the following lines: {% set power_on_command = 'python ./root/power-control/ppson.py' %} {% set power_off_command = 'python ./root/power-control/ppsoff.py' %} {% soft_reboot_command = 'reboot' %} {% hard_reset_command = 'python ./root/power-control/ppsoff.py && sleep 5 && python ./root/power-control/ppson.py' %} With those lines we are trying to trigger the scripts, which control our power supply directly. Do we have to pay attention to the python dependencies in the scripts or could the error be in the definition itself? We thought, that we had at least configured the device dictionary sufficiently to have a connection to the device and start a very basic health check. Our device runs Linux, which is running Android on top. The Ser2Net connection has been configured according to the instructions on the repo as well (using the telnet command by itself worked fine). So we specified the health check like this: device_type: rsu job_name: Health Check for RSU timeouts: job: minutes: 30 action: minutes: 5 connection: minutes: 2 priority: medium visibility: public actions: - deploy: namespace: tlxc timeout: minutes: 5 to: lxc packages: - android-tools-adb - android-tools-fastboot - boot: method: lxc prompts: - 'root@(.*):/#' timeout: minutes: 5 - test: timeout: minutes: 4 definitions: - repository: metadata: format: Lava-Test Test Definition 1.0 name: hello-world description: "say hello" os: - android scope: - functional run: steps: - apt -q update - pwd - echo "echo hello" # remember to use -y to allow apt to proceed without interaction # -q simplifies the apt output for logging. from: inline name: hello-world path: inline/hello-world.yaml When executing, we got the following error: [cid:image002.png@01D6EE7E.9CED3690] Could you please give us some advice, on how to define a test job/health check for a device, which uses fast-boot and Android? Your help would be greatly appreciated.

Define "Missing key" Whitelist

by Westermann, Oliver

Hey, we recently updated our LAVA setup from 2020.06 to 2020.12. After a few hickups we’re back running, but we are greeted with a few new warnings: Our setup uses the iMX8 and the UUU boot method, which uses several, internal variables. Internal = Internal to U-Boot or bash, for example: > FB: ucmd setenv fastboot_buffer ${loadaddr} > FBK: ucmd mkfs.ext4 -F -E nodiscard /dev/mmcblk${mfg_mmcdev}p1 With the recent LAVA version, this causes a warning: {"dt": "2021-01-25T07:43:46.551216", "lvl": "warning", "msg": "Missing key : '{mfg_mmcdev}' for string 'ucmd mkfs.ext4 -F -E nodiscard /dev/mmcblk${mfg_mmcdev}p1'"} While I could reduce this by removing the brackets in the first case, this won’t work for the second case. Is there a way to provide eg a variable whitelist? The 30 warnings boil down to 4-5 variables, so this might be a useful feature addition. Any other ideas of cause welcome, maybe I will try to use this for my first contribution here 😊 Best regards, Olli

Docker transfer_overlays problem

by Seb Seb

Hi, I am having a problem with using the transfer_overlays command for a dispatcher in docker. I cannot set the dispatcher ip no matter what I try. I have tried using the API here : " http://10.1.51.55/api/v0.2/workers/docker_dispatcher_hostname/config/" but I get this error when posting : ""detail": "CSRF Failed: CSRF token missing or incorrect.", I have tried another browser already. I have also tried creating a dispatcher.yaml file in these locations : /etc/lava-server/dispatcher.d/lava-dispatcher ; /etc/lava-server/dispatcher.d/ ; /etc/lava-server/dispatcher.d/lava-master. The ip I have set is simply ignored. Could anybody help please? Thanks

Ask android vts test link in docker test shell.

by Larry Shen

Hi, guys, Recently we are running android VTS test in lava docker test shell, but find all MTP cases fail. It reports: 01-08 07:42:38 D/ModuleDefinition: Running module armeabi-v7a HalUsbGadgetV1_0HostTest 01-08 07:42:43 I/ModuleListener: [1/5] com.android.tests.usbgadget.HalUsbGadgetV1_0HostTest#testMtp FAILURE: java.lang.AssertionError: MTP not present at org.junit.Assert.fail(Assert.java:88) at org.junit.Assert.assertTrue(Assert.java:41) at com.android.tests.usbgadget.HalUsbGadgetV1_0HostTest.testMtp(HalUsbGadgetV1_0HostTest.java:113) I'm a little lost currently, so before I have a deep investigation, I want to know if you can share a link about this case: com.android.tests.usbgadget.HalUsbGadgetV1_0HostTest#testMtp I know you guys run android tests on other product always, could share a link for us to reference? Or with good luck you know what's the potential root cause for my failure? Thanks.

LAVA apt install packages

by Philippe Mazet (OSS)

Hi, It looks like the apt release is stuck to version 2019.11: https://apt.lavasoftware.org/release/dists/buster/Release Do I miss something? Then I tried to use the daily apt source to install a worker (deb https://apt.lavasoftware.org/daily buster main, mentioned on https://docs.lavasoftware.org/lava/installing_on_debian.html#debian-install…), but then I have a version mismatch with my master... Sorry to insist... but this version check is really a pain for us. A warning instead would be much more convenient. Could you please let me know how could I force install of 2020.10 for example? (I mean, a native install, not using Docker) Thank you very much, Philippe

Re: [Lava-users] Unable to upgrade lava server/workers 2020.10

by koti koti

Hi, Try to list the available lava versions in your distro initially using the command "apt policy lava" and downgrade using "sudo apt install <package version>" . But, there may be cases in which you must resolve some dependencies to be able to downgrade the package through. Hope this may helps you i.e https://www.linuxuprising.com/2019/02/how-to-downgrade-packages-to-specific… *Note*: We have not tried this so far. AFAIK before executing these commands, make sure you take the backup of your lava modified/configuration files which you have changed for your production/running setup. Best of luck!!.
