fastmodel kernel command line apparently missing

[Riku Voipio]

The semihosting command line should look something like:

 -C cluster.cpu0.semihosting-cmd_line="--kernel vmlinuz.... --dtb rtsm_ve-cortex_a15x1.dtb --initrd initrd--console=ttyAMA0,115200n8 root=/dev/mmcblk0p2 rootwait ro mem=1024M "

(for fast models with big.LITTLE use coretile.cluster0.cpu0.semihosting-cmd_line instead)

Looking at lava submissions for fast models. there is no semihosting-cmd_line included.

[Alexander Sack (asac)]

isn't there a way to tweak the model command line options through lava job parameters?

[Fathi Boudra (fboudra)]

we can pass options:

 {
        "command": "boot_linaro_image",
        "parameters": {
                "options": [
                        "coretile.cluster0.cpu0.semihosting-cmd_line=\"--kernel uImage --dtb $RTSM_DTB --initrd $RTSM_INITRD -- $RTSM_CMDLINE\""
                ]
 }

See http://bazaar.launchpad.net/~linaro-validation/lava-dispatcher/trunk/view/head:/lava_dispatcher/default-config/lava-dispatcher/device-types/fastmodel_A15x4-A7x4.conf for reference.

I think this will be fixed once https://blueprints.launchpad.net/lava-dispatcher/+spec/untangle-boot-commands-from-dispatcher this BP is pushed in ?

[Riku Voipio (riku-voipio)]

I did some more digging. Passing the options as suggested by Fathi doesn't work:

http://validation.linaro.org/lava-server/scheduler/job/51767/log_file

We see that lava-dispatcher does not copy from inside the image the needed uImage, uInitrd and dxb file - just the axf file.

[Antonio Terceiro (terceiro)]

This is weird. I can reproduce this at validation.linaro.org, but not locally yet with an old image I had on my disk.

I am downloading the same that was used in the job report mentioned Riku's original report to test locally

[Antonio Terceiro (terceiro)]

OK - so i reproduced the problem with the linux-vexpress-kvm image. Maybe the problem is that something in the new images changed and lava was not updated to deal with that.

[Antonio Terceiro (terceiro)]

hey guys, could you please give me some feedback on the branch that tries to solve this?

https://code.launchpad.net/~terceiro/lava-dispatcher/fastmodels-semihosting-fix/+merge/161258

it's not complete, but I would like some feedback before going on with this.
