Unable to boot BuildRoot/Fedora on BOOM core

[Alenkruth Krishnan Murali]

Hello everyone,

I have been trying to boot Buildroot/Fedora on (Large)Boom core for sometime now but I have not been successful. I am following the documentation to run a single node simulation on Xilinx Alveo U250.

I was able to boot Buildroot and Fedora on a single rocket core without NIC but not on BOOM. I have tried with both Large and Giga BOOM configurations. I build the linux image by following the steps indicated in the documentation and I am not trying to run any custom workloads.

When I issue the runworkload command, the simulation starts and I get the status screen but when I resume the screen session I observe the following log.

Script started, output log file is 'uartlog'.

UART0 is here (stdin/stdout).

TraceRV 0: Tracing disabled, since +tracefile was not provided.

The boot freezes at this point and I have to manually interrupt the firesim simulation and force close the terminal. I cannot find the uartlog file in the results directory. Moreover I could not run firesim infrasetup again before rebooting the machine since I had issues with xdma which were caused by terminating the simulation forcefully.

I am using Firesim for the first time and I am not sure how to fix this. It would be very helpful if someone has any pointers they can share.

Thank you!

Hi Alenkruth,

It seems you're not executing a fedora workload but the linux-uniform one:

Have you updated the workload in YOUR_FIRESIM_REPO/deploy/config_runtime.yaml?

workload:

workload_name: fedora-uniform.json

#workload_name: linux-uniform.json

terminate_on_completion: no

suffix_tag: null

Best,

d.

l also tried to boot Fedora on a Rocket core in a Xilinx Alveo U200 but the booting process freezes after executing OpenSBI:

We recently patched the Fedora build in FireMarshal (see commit: https://github.com/firesim/FireMarshal/commit/731550e5defbc05c50eb4ad8a3618d6001443088). You should apply this patch and/or bump FireMarshal to get it. I think that should fix your issue (though I haven't tried it myself).

Thanks! The indicated patch solves the issue.

Thanks for the reply and sorry for the confusion. The log I posted here is from the time I tried booting the linux-uniform (buildroot) image on the BOOM core. Irrespective of the workload (buildroot or fedora) I face the same problem and so I did not add the log from the time I tried booting fedora. As of writing this, I still face the same issue.

On the other hand, I was able to boot fedora and buildroot on the ROCKET core without any problems after bumping FireMarshal which Abraham Gonzalez mentioned.

Thanks,

Alenkruth.

Hi Alenkruth,

I've changed the default_hw_config in config_runtime.yaml to firesim_boom_singlecore_no_nic_l2_llc4mb_ddr3 and was able to boot Linux on my U200 board:

Hi David,

Thank you for your help. Am I right in assuming that you used "alveo_u200_firesim_boom_singlecore_no_nic_l2_llc4mb_ddr3" as the default_hw_config in config_runtime.yaml? You have mentioned you used that recipe to build the bitstream.

Based on my assumption, I went ahead and modified the previous entry in config_build_recipes.yaml to resemble your recipe but with the GigaBoom Config in place of the LargeBoom config. You can find my recipe as follows.

alveo_u250_firesim_gigaboom_corefuzzing_singlecore_no_nic:
    PLATFORM: xilinx_alveo_u250
    TARGET_PROJECT: firesim
    DESIGN: FireSim
    TARGET_CONFIG: DDR3FRFCFSLLC4MB_WithDefaultFireSimBridges_WithFireSimTestChipConfigTweaks_chipyard.GigaBoomConfig

    PLATFORM_CONFIG: WithAutoILA_BaseXilinxAlveoConfig
    deploy_quintuplet: null
    platform_config_args:

        fpga_frequency: 50

        build_strategy: TIMING
    post_build_hook: null
    metasim_customruntimeconfig: null

    bit_builder_recipe: bit-builder-recipes/xilinx_alveo_u250.yaml

When I tried running the default Buildroot workload, I get the same error as before. I will be trying again with LargeBoom configuration shortly.

I will report back if that works. In the meanwhile, can you check if you are able to boot linux on a GigaBoom configuration. Before you generate the bitstream you might have to update the numFetchBufferEntries to a multiple of 5 in this line within boom/src/main/scala/common/config_mixins.scala within chipyard.

Thank you for your help,

Alenkruth

[Alenkruth Krishnan Murali]

Hey David,

I have tried running with the LargeBoom configuration but the simulation freezes at the same point.

Based on your logs, I can see that this error occurs just before

FireSim fingerprint 0x46697265

This makes me think if the simulation freezes because of a fingerprint mismatch. Have you made any changes to your Boom source code or Rocket-chip source code?

Thank you,

Alenkruth.

[Novo Bruna David]

Hi Alenkruth,

I haven't made any changes to the source code and I confirm I can successfully boot Linux in the GigaBoom configuration you suggested.

Your problem doesn't seem to be related to Linux booting. Have you tried executing a bare-metal workload? I anticipate that you may encounter the same issue.

Best,

d.

[Alenkruth Krishnan Murali]

HI David,

Thank you for replying and trying out with the GigaBoom Configuration. It is interesting to know that you are able to boot with the GigaBoom configuration.

I have not tried with a bare-metal workload. I have been looking around the documentation to find how to run a bare-metal workload on the FPGA. Do you happen to have a link to any documentation. 

As of now, I have been able to generate the default baremetal RISCV executables(hello) using firemarshal. What modifications should I be doing to the config_runtime.yaml for firesim infrasetup and firesim runworkload to pick up the baremetal workload?

Thank you,

Alenkruth
