Hello, while searching for possibilities of testing external interfaces of my DUTs I found this presentation: https://wiki.linaro.org/Internal/lava/Lava-lmp?action=AttachFile&do=get&tar… Is the LAVA LMP project still active? If yes, how can I find information on this?

u-boot one-too-many prompt problem

by Dan Rue

I'm sorry, as surely this is an FAQ but I've spent quite a bit of time troubleshooting and reading. This is very similar to Kevin's thread from May subject 'u-boot devices broken after 2018.4 upgrade, strange u-boot interaction'. In that thread's case, the issue was that interrupt_char was being set to "\n". My symptoms are the same, but interrupt_char is set to " " or "d". I'm running LAVA from the latest released containers (2018.11), and trying to use a beaglebone-black with a more recent u-boot than exists in validation.l.o. qemu works fine. The problem seems to be that LAVA thinks there's a prompt when there isn't, and so it sends commands too quickly. Here's example output from the serial console (job link[2]): U-Boot 2017.07 (Aug 31 2017 - 15:35:58 +0000) CPU : AM335X-GP rev 2.1 I2C: ready DRAM: 512 MiB No match for driver 'omap_hsmmc' No match for driver 'omap_hsmmc' Some drivers were not found MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 Net: cpsw, usb_ether Press SPACE to abort autoboot in 10 seconds => => setenv autoload no => setenv initrd_high 0xffffffff => setenv fdt_high 0xffffffff => dhcp link up on port 0, speed 100, full duplex BOOTP broadcast 1 BOOTP broadcast 2 BOOTP broadcast 3 DHCP client bound to address 10.100.0.55 (1006 ms) => 172.28.0.4 Unknown command '172.28.0.4' - try 'help' => tftp 0x82000000 57/tftp-deploy-t7xus3ey/kernel/vmlinuz link up on port 0, speed 100, full duplex *** ERROR: `serverip' not set ... When I u-boot manually, after I hit SPACE (or 'd', both work), u-boot *deletes* the character and then prints '=> ' (is that delete the root cause?). When LAVA runs, it shows an extra => and starts typing as seen above. dhcp takes a second or two, and so the subsequent command starts to get lost (in the above log we see an IP, because 'setenv serverip' got lost). If I set boot_character_delay to like 1000, it works because it gives enough time for dhcp to finish before typing the next character, but obviously makes the job very slow, and still not reliable. I'm out of ideas.. help? P.S. Two interesting things I've learned recently: 1) boot_character_delay must be specified in device_types file. it's ignored when specified in the device file (surprising, as I see it listed in some people's device files[3]). 2) If you install ser2net from sid, you can set max-connections and do some _very handy_ voyeurism on the serial console while lava does its thing (hat tip Kevin Hilman for that one).

Re: [Lava-users] reboot during test

by cnspring2002

100 testcases, submit to lava before leave the office, expect to get all the results next morning. If everything is ok, get 100 results next morning, and check every issues. Then, e.g. the 10th cases OOM, I wish from 11st case to 100th cases can continue run during the night, so I want to reboot the device after 10th case which I find it OOM. Then after reboot, continue 11st case to 100 the cases. I know OOM not automation related, but if I do not resume the 11st ~ 100th cases during this night. I had to resubmit these cases tomorrow morning after I back to office, maybe the 100th case also have some bug, I wish it could send a result, then that morning I could assign other guy to fix it quickly, not wait I back to office then remove the 10th issue case, resubmit it, wait another 8 hours, finally execute the 100th case. 8 hours passed, we do not want the process's efficiency so low!

Not necessarily. From the LXC, the device can be controlled using USB. There is no need for devices to have a direct connection to each other just to use MultiNode. The shards implementation may require that though. > Karsten shared a job example here[1].

There is a problem in this model: Every DUT will have it's own LXC and that device will be connected to the LXC using USB. > master.lxc <----adb over usb----> master.dut > master.lxc <----adb over tcpip ---> slave1.dut > master.lxc <----adb over tcpip ---> slave2.dut Do not separate the LXC from the DUT - the LXC and it's DUT are a single node. Master DUT has a master LXC. Slave1 DUT has a Slave1 LXC Slave2 DUT has a Slave2 LXC. Depending on the boards in use, you may be able to configure each DUT, including the master DUT, to have TCP/IP networking. That then allows the processes running in the Master node to access the slave nodes. (The following model is based on a theoretical device which doesn't have the crippling USB OTG problem of the hikey - but the hikey can work in this model if the IP addresses are determined statically and therefore are available to each slave LXC.) 0: A program executing in the Master LXC which uses USB to send commands to the master DUT which allow the Master LXC to retrieve the IP address of the master DUT. 1: That program in the Master LXC then uses the MultiNode API (lava-send) to declare that IP address to all the slave nodes. This is equivalent to how existing jobs declare the IP address of the device when using secondary connections. 2: Each slave node waits for the master-ip-addr message and sets that value in a program executing in the slave LXC. The slave LXC is connected to the slave DUT directly using USB so can use this to set the master IP address, if that is required. 3: Each slave node now runs a program in each slave LXC to connect to the slave DUT over USB and extract the slave DUT IP address 4: Each slave node then broadcasts that slave-<ID>-ip-addr message, so the first slave sends slave-1-ip-addr containing an IP address, slave 2 sends slave-2-ip-addr containing a different IP address. 5: The master node is waiting for all of these messages to be sent and retrieves the values in turn. This information is now available to a program executing inside the master LXC. This program could use USB to set these values in the master DUT, if that is required. 6: During this time, all the slave nodes are waiting for the master node to broadcast another message saying that the work on the master is complete. 7: Once the master sends the complete message, each slave node picks up this message from the MultiNode API and the script executing in the slave LXC then ends the Lava Test Definition and the slave test job completes. 8: The master can then do some other stuff and then complete. https://staging.validation.linaro.org/scheduler/job/246447/multinode_defini… https://staging.validation.linaro.org/scheduler/job/246230/multinode_defini… Don't obsess about the LXC either. With upcoming changes for docker support, we could remove the presence of the LXC entirely. The LXC with android devices only exists as a unit of isolation for the benefit of the dispatcher. It has useful side effects but the reason for the LXC to exist is to separate the fastboot operations from the dispatcher operations. For hikey and it's broken USB OTG support: 0: Each slave test job turns off the USB OTG support once the slave LXC has deployed all the test image files and determined that the slave DUT has booted correctly. If not, use lava-test-raise. 1: Next, each slave LXC uses the IP address of it's own slave DUT to check connectivity. If this fails, use lava-test-raise. 2: Each slave LXC uses the MultiNode API to declare the IP address of the slave DUT (because the slave node has determined that this IP is working). 3: The master node is waiting for these messages and these are picked up by the master LXC test definition. 4: The master LXC test definition issues commands to the master DUT - now depending on how the sharding works, this could be over USB (turn the USB OTG off later) or over TCP/IP (turn off the master USB OTG at the start of this test definition). 5: The master DUT has enough information to drive the sharding across the slave DUTs. The slave LXCs are waiting for the master to finish the sharding. (lava-wait) 6: When the master LXC determines that the master DUT has finished the sharding, then the master LXC sends a message to all the slave nodes that the test is complete. 7: Each slave node picks up the completion message in the slave LXC and the test definition finishes. 8: The master node can continue to do other tasks or can also complete it's test definition. > .... > > I see two options for adb over tcpip. > > Option #1: WiFi. adb over wifi can be enabled easily by issuing adb > cmds from lxc.

Before the OTG is switched, all data from the DUT needs to be retrieved (and set) using the USB connection. What information you need to set depends on how the sharding works. The problem, as I see it, is that the slave DUTs have no way to declare their IP address to the slave LXC once the OTG port is switched. Therefore, you will need to put in a request for the boards to have static IP addresses declared in the device dictionary. Then the OTG can be switched and things become easier because the LXC knows the IP address and can simply declare that to the MultiNode API so that the master LXC can know which IP matches which node. There are already a number of hikey devices with the static_ip device tag and you can specify this device tag in your MultiNode test definition. > > * Without context overriding, overlay tarball will be applied to > '/system' directory and test job reported "/system/bin/sh: Why are you talking about /system ??? MultiNode only operates in a POSIX shell - the POSIX shell is in the LXC and each DUT has a dedicated LXC. In this use case, MultiNode API calls are only going to be made from each LXC. The master LXC sends some information and then receives information from test definitions running in each of the slave LXCs. The overlay is to be deployed to the LXC, not the DUT because this is an Android system. What the android system does is determined either by commands run inside the slave LXC to deploy files (before the OTG switch) or commands run inside the master LXC (with knowledge of the IP address from the MultiNode API) to execute commands on the DUT over TCP/IP. Use the LXC to deploy the files and boot the device, then to declare information about each particular node. Once that is done, whatever thing is controlling the test needs to just use TCP/IP to communicate and use the MultiNode API to send messages and allow some nodes to wait for other nodes whilst the test proceeds. > /lava-247856/bin/lava-test-runner: not found"[2]. > * With the following job context, LAVA still runs > '/lava-24/bin/lava-test-runner /lava-24/0' and it hangs there.

I don't see that this solves anything and it adds a lot of unnecessary lab configuration - entirely duplicating the point of having ethernet connections to the boards. Assign static IP addresses to each board and when the test job starts, each dedicated LXC can declare the static information according to whichever board was assigned to whichever node. The DUTs only need to be visible to programs running on the master node and that can be done by declaring static IP addresses using the MultiNode API. > * In single node job, LAVA needs to add the DUTs specified(somehow) or > assigned randomly(lets say both device type and numbers defined) to > the same lxc container. Test definitions can take over from here. No - the LXC is used to issue commands to deploy test images to the DUT. The LXC is a transparent part of the dispatcher, it is not just for test definitions. The LXC cannot be used for multiple test jobs, it is part of the one dispatcher. > > Is this can be done in LAVA?

So I trigger the device to reboot, Then all left case cannot run . I can not use multiple boot when define job in advance because I can not predict which case will make OOM, what you suggest doing? The out of memory killer is a fatal device error. The test job is not going to be able to continue because the failure mode is unpredictable.

I didn't realize static-ip tag is the solution. I have managed to enable and test adb over tcpip in this way(In my local instance). I have attached my test job definition here in case it is any help for other LAVA users. The following definitions are essential. tags: - static-ip reboot_to_fastboot: false - test: namespace: tlxc timeout: minutes: 10 protocols: lava-lxc: - action: lava-test-shell request: pre-os-command timeout: minutes: 2 Thanks, Chase > > > > > * Without context overriding, overlay tarball will be applied to > > '/system' directory and test job reported "/system/bin/sh: > > Why are you talking about /system ???

Reboot DUT during job execution

by Diego Russo

Hello, we have the need to perform tests that require reboots of the DUT between their executions. Few examples are to check rootfs upgrades or to check configurations changes to persist . I have few questions: * Does LAVA support those cases? * If yes, does LAVA support multiple reboots? * If yes, how can I write tests in order to run different sets of tests at any boot. * Example: 1) do an upgrade 2) reboot the device 3) Check if the upgrade was successful * How can I structure my pipeline?

Piece of advice to combine interactive boot and Linux testing

by Denis HUMEAU

Dear Lava users, I'm trying to create a job that performs the following steps : Deploy to flasher our custom tool (OK) Boot in bootloader mode - u-boot (OK) Test in interactive mode (OK) From interactive mode start kernel (OK) Launch a test from kernel (KO) The last part fails because I don't know where to check the kernel prompt. I cannot add a boot stage and declare an additional prompt because I don't want to reboot, that would reset the configuration done in interactive mode. Do you have any piece of advice or example of job showing how to proceed to manage the kernel prompt & autologin in such a job? Best regards, Denis

check boot stages versions in a Lava job

by Denis HUMEAU

Hello, A request from some Lava users internally. We have 3 boot stages, TF-A, U-boot, and kernel. Is there a way, in a Lava job, to test that these components' versions are the expected ones? That would mean, as far as I understand, not testing the embedded software itself, but the Lava job log... Best regards, Denis
