IOZone test to measure performance of DUT

by Florence ROUGER JUNG

Hi All, We use IOZone test to measure performance of our DUT Same command executed several time in a Lava session provide a diversity of results iozone -az -i0 -i1 -I -e -s 100M -r 4k -r 16k -r 512k -r 1024k -r 16384k -f /mnt_emmc//tmp/iozone.tmp Example1: kB reclen write rewrite read reread read write read rewrite read fwrite frewrite fread freread 102400 4 5053 4420 12471 12137 102400 16 5070 5218 22101 22207 102400 512 11733 12630 40799 40862 102400 1024 11446 11494 39982 39976 102400 16384 13839 14235 42093 42094 Example 2: kB reclen write rewrite read reread read write read rewrite read fwrite frewrite fread freread 102400 4 5088 5006 13496 13095 102400 16 5395 5549 17199 17220 102400 512 9203 10038 27819 27586 102400 1024 9382 8482 32514 32430 102400 16384 13569 13986 41992 42081 When same command is executed without LAVA with same DUT, results are more homogeneous (similar to exemple1) and permit to define clear targets How to reduce interaction from Lava to measure performance of DUT ? Is it possible to disable some checks / interactions with DUT during execution of each test (around 3 / 4 minutes) ? Thanks in advance for your answer Florence Rouger-Jung

Using power-on command with pyocd boot method

by Andrei Narkevitch

Hi, our boards are powered via PDU and before flashing with pyocd, they need to be powered up first. I defined power_on_command in the device dictionary, but it is ignored. It looks like an only limited set of methods add ResetDevice action to the pipeline and pyocd is not among them. Contrarily, if defined, power_off command always gets invoked because it is added by FinalizeAction to every test. I'm wondering if there is any way to issue the power-on command without modifying the dispatcher pipeline source code. Thanks, Andrei Narkevitch, Cypress Semiconductor This message and any attachments may contain confidential information from Cypress or its subsidiaries.

Request to know one example on prepare-scp-overlay

by Chetan Sharma

Hi Everyone Can anyone share sample Yaml File and Usecase using "prepare-scp-overlay" using MultiNode. Some calls can only be made against specific actions. Specifically, the prepare-scp-overlay action needs the IP address of the host device to be able to copy the LAVA overlay (containing the test definitions) onto the device before connecting using ssh to start the test. This is a complex configuration to write. -- Thanks & Regards Chetan Sharma

lava-tool wait-job-events

by Loys Ollivier

Hello everyone, I am using lava-tool to monitor my jobs. Previously I used: $ lava-tool submit-job --block Using version of lava-tool 0.23 I now have this message: --> This kind of polling is deprecated and will be removed in the next release. Please use "wait-for-job" command. But "wait-for-job" doesn't exist. There is a "wait-job-events" option though. I tried this one and it doesn't return even once the job has finished. If I manually stop it and restart it with the same job number I get as output: --> Job already finished with status Complete. Command I'm using: $ lava-tool wait-job-events --job-id 20 http://user@lava-server Is there anything I'm doing incorrectly ? Or are you aware of this bug ? Thanks ! -- Loys OLLIVIER

Booting with Coreboot/Depthcharge

by Guillaume Tucker

A change was sent a while ago to add support for the Coreboot / Depthcharge bootloader which is used on Chromebook devices. This is useful in particular to avoid having to install U-Boot on Chromebook devices. See this Gerrit review here for previous history: https://review.linaro.org/#/c/15203/ I'm now opening this case again to try and get this resolved, there seem to be several issues with the original patch that would need to be clarified. Also, some things might have changed since then in LAVA or Coreboot which could potentially lead to a different approach - any feedback on this would be welcome. To start with, I understand that running mkimage on the dispatcher is not a valid thing to do, it should receive a FIT (flattened image tree) kernel image ready to be booted. This complicates things a bit for projects like kernelci.org where only a plain kernel image is built and ramdisks are served separately, but it's fair enough to say that LAVA is not meant to be packaging kernel images on the fly. Then I believe creating the command line file in LAVA should be fine, although it probably makes more sense to have both the FIT image and cmdline file generated by the same build system. In any case, both files would need to be served from the dispatcher TFTP server to the target device running Coreboot / Depthcharge. So the idea was basically to have an option in Coreboot / Depthcharge to interactively tell it where to find these files for the current job to run, say: <JOB_NUMBER>/tftp-deploy-<RANDOM>/kernel/vmlinuz <JOB_NUMBER>/tftp-deploy-<RANDOM>/kernel/cmdline It looks like the current patch in Gerrit relies on this location to be hard-coded in the bootloader, which works fine for a private development set-up but not for LAVA. To recap, my understanding is that the "depthcharge" boot support code in LAVA would need to: * maybe create the cmdline file with basically the kernel command line split up with one argument per line * or just download the cmdline file along with the vmlinuz FIT * place both the cmdline and vmlinuz FIT files in the job's TFTP directory on the dispatcher * turn on the device and open the serial console... * interactively pass at least the path to the job TFTP directory on the serial console (and if possible the server IP address as well, and maybe even the individual file names rather than hard-coded vmlinuz and cmdline) * look for a bootloader message to know when the kernel starts to load and hand over to the next action (login...) Please let me know if this sounds reasonable or if we should be doing anything differently. I think it would be good to have some agreement and a clear understanding of how this is going to be implemented before starting to work on the code again. Best wishes, Guillaume

LAB Notice: LAVA Instance downtime

by Dave Pigott

[bcc’d to everyone] Hi all, Next week, starting on Monday, we will be upgrading all the LAVA servers to Debian Stretch and then upgrading to LAVA 2018.01. This will involve minimal downtime for each instance. Devices will be off-lined ahead of each upgrade. The order of upgrade will be: Monday: LNG: lng.validation.linaro.org PMWG: pmwg.validation.linaro.org Tuesday: Production: validation.linaro.org LKFT: lkft.validation.linaro.org All being well, the downtime, i.e. the time you will not be able to submit jobs or see the web site, will be of the order of one hour per instance. If that is going to change I will send out a new notification. Thanks for your patience, Dave ---------------- Dave Pigott LAVA Lab Lead Linaro Ltd t: (+44) (0) 1223 400063

No result coming when job submitted in lava

by Gumansingh, Smita

Hi, I am new to lava and trying to submit a job on lava scheduler ,job submitted nut no result is coming. I am trying to test the CIP Kernel on the Beaglebone Black(board is physically connected to my linux machine). Health checkup is working somehow . I am following the steps from here https://wiki.linuxfoundation.org/civilinfrastructureplatform/ciptestingrefe… Pre-requise: 1. I have built(cip_v4.4.92) the CIP Kernel with Kernel CI as the steps mentioned in https://wiki.linuxfoundation.org/civilinfrastructureplatform/cipsystembuild… 2.Target is booted and up and flashed with debian 4.9 rootfs Job Definination is pasted here https://pastebin.com/YwnPXidK Need help for going further !!!! Thanks & Regards, Smita Gumansingh

Better bootloader failure detection

by Matt Hart

Currently it is difficult to tell the difference between an infrastructure problem in a device bootloader, or a kernel failure. If a kernel silently fails to boot, LAVA throws a bootloader-commands timeout because it hasn’t matched ‘Linux version’ to know the kernel has started. However, this timeout could also be caused by a real problem in the bootloader, such as a DHCP failure or a TFTP timeout. KernelCI would like to catch actual infrastructure problems in the bootloader, but can’t tell if the kernel just didn’t boot, or the commands actually timed out in the bootloader. To fix this, we're going to: - change the bootloader-commands action to finish when it has sent the last command - have auto-login-action takeover monitoring the kernel boot process - extend bootloader-commands to match more infrastructure problems - update uboot commands to execute the commands in order (like the other bootloader implementations), rather than building a script and then calling that as the last command This work is scoped for the January 2018.1 LAVA release.
