firesim setup - building target sw

[Varun Gandhi]

Hi,

I'm trying to build the default linux distro as described in the firesim setup instructions by invoking:

./marshal -v build br-base.json

Error log

Would appreciate some guidance.

As suggested in the error message, I recommend running "./init-submodules.sh" in the firemarshal directory.

FireMarshal doesn't initialize submodules eagerly since they can be quite large and slow to checkout and aren't needed for bare-metal workloads.

Thanks for pointer. However, my build is still failing…

Later in the output there should be a reference to a more complete log. Could you post that here? It should contain the full output of the linux build. The Linux source is at boards/firechip/linux, you might double check that everything looks OK in there and run "make mrproper" (Linux's confusingly named clean command), just to be sure. You may also try "git status" and "git submodule status" to make sure everything looks OK with submodules, git is a dark and mysterious magic that can get itself into weird states sometimes.

Here’s the complete log

Also,

1. git status  — shows a few changes; presumably from the last failed build

1.1  target-design/chipyad  (modified content)

1.2  sim/firesim-lib/src/main/cc/lib/elfutils (modified content)

1.3  sim/firesim-lib/src/main/cc/lib/libdwarf (untracked content)

2. git submodule status — up to date

The Linux source is at boards/firechip/linux, you might double check that everything looks OK in there and run "make mrproper" (Linux's confusingly na clean command), just to be sure.

I don’t see a boards/firechip/linux; instead there is a '/firesim/target-design/chipyard/software/firemarshal/boards/firechip/base-workloads/br-base’. Is this the directory you’re referring to?

Best,

Varun

There should be 
/firesim/target-design/chipyard/software/firemarshal/boards/firechip/linux

it is a symlink to 

/firesim/target-design/chipyard/software/firemarshal/boards/default/linux

If those aren't there, something is wrong with your git repo and you may just have to reclone or something. The log output would imply that marshal is finding the linux source so I would expect those directories to exist.

Looking at the log I see a bunch of errors saying "resource unavailable" and "no child processes". I'm not sure what that means but something sounds wrong in your environment. This may just be a "turn it off and on again" sort of situation (reboot and reclone?). Let us know if you can reproduce on a fresh clone.

[Varun Gandhi]

Recloned the firesim repo 

Ran 

1. ./build-setup.sh fast in firesim

2. Init-submodules.sh in firemarshal

but still don’t see

/firesim/target-design/chipyard/software/firemarshal/boards/firechip/linux

And 

/firesim/target-design/chipyard/software/firemarshal/boards/default/linux

I’ve followed the setup documentation to the letter and tried rebooting my aws manager instance too.
