Subject: Query on 5.3 Foundation model support in LAVA

 

Hi,

 

We were trying to get the latest published (5.3) foundation models in LAVA.

 

Using the reference as http://git.linaro.org/lava/lava-dispatcher.git/blob/HEAD:/lava_dispatcher/default-config/lava-dispatcher/device-types/rtsm_foundation-armv8.conf

 

# The new (2013-10-03) Foundation model install places the simulator binary at Foundation_v8pkg/models/Linux64_GCC-4.1/Foundation_v8

21 # A symbolic link has been created in our arm_models-2013-10-03.tgz package to workaround this change for compatibilty sake. If you are getting an error

22 # chances are you are running a newer Foundation model and need to adjust this path. 

23 simulator_command = sudo -u www-data /opt/arm/Foundation_v8pkg/Foundation_v8 --image={AXF} --block-device={IMG} --network=nat

 

Not quite sure what the comment refers to. However the key point for me is that rather than using the axf file I was hoping to define the boot options similar to what we have for the Base models.


This comment refers to the older foundation models:

 - Older version of the foundation models have binaries in different locations:

tyler@i5-vm:~/Downloads/models/Foundation_v8pkg$ ls -al
total 24
drwxrwxrwx 5 tyler tyler 4096 Jan 22 16:37 .

drwxrwxrwx 3 tyler tyler 4096 Jan 22 16:35 models


So symlinks were created inside the foundation model tar ball package that we deploy into the lab to maintain backward compatibility with the older models.

If you don't care about older version of the foundation models, you need to adjust your simulator_command to the proper path for the new model:

New model:

 - simulator_command = sudo -u www-data /opt/arm/Foundation_v8pkg/models/Linux64_GCC-4.1/Foundation_v8--image={AXF} --block-device={IMG} --network=nat

Old model:

 - simulator_command = sudo -u www-data /opt/arm/Foundation_v8pkg/Foundation_v8--image={AXF} --block-device={IMG} --network=nat
 

 

The following is the typical boot options I wanted to use

 

<path-to>/Foundation_v8                   \

--cores=4                                 \

--no-secure-memory                        \

--visualization                           \

--gicv3                                   \

--data="<path to bl1.bin>"@0x0            \

--data="<path to UEFI binary>"@0x8000000  \

--block-device="<path-to>/vexpress64-openembedded_lamp-armv8_20130927-7.img"

 

This would let me override the various argument like number of cores / --gicv3 or –no-gicv3 flag.


https://git.linaro.org/lava/lava-dispatcher.git/blob/HEAD:/lava_dispatcher/default-config/lava-dispatcher/device-types/rtsm_foundation-armv8.conf

At Linaro we have only had the need to use the boot_option "cores" as seen above. Feel free to add any options you would like here :) You can add these options in either your device configuration or device-type configuration.
 

 

My understanding is that foundation models are quite cutdown version of Base models and hence does   not have semihosting capabilitie etc, hence the uefi and blockdevice path should be relative to that of the foundation model location.


I believe you are correct here. I have never tried this with a foundation model though.
 

 

Question:: Can we use the boot options for foundation model the similar way it is used for base models?  Is there an example for the same where we could cross-reference?


The answer is yes you can, here is an example on the base model:

http://community.validation.linaro.org/scheduler/job/2686/definition

Works the same way on the foundation model as it does on the base model.
 

 

Thanks
