Firemarshal and NVDLA: failure after executing guestunmount

[Flipfle]

Impact: software

Tell us about your environment: Chipyard Version: master branch, newest Hash: 02adf86

OS: CentOS Linux 8, 64 bit I work on a server, so I don’t have sudo permissions.

Other: I installed Chipyard like in „1.4. Initial Repository Setup“ written. I want to execute CNNs on an NVDLA using Firemarshal.

I followed orders in the ReadMe.md in directory nvdla-workload. So, I edited the Kconfig file in software/firemarshal/boards/default/linux/drivers/gpu/drm and replaced boolwith bool "GEM CMA Helper Functions“ under config DRM_GEM_CMA_HELPER . Additionally, I checked out in software/firemarshal/boards/linux to branch nvdla-linux-v57.

I executed the command ./marshal -v build /home/ulnor/Dokumente/micro_Kernel_project/00_Repos/chipyard/software/nvdla-workload/marshal-configs/nvdla-large-resnet50.json. I just took this workload to understand how everything works.

What is the current behavior? The program runs into an error when it tries to unmount the disk-mount.

What is the expected behavior? This command should run without an error.

Other information

The last lines of the output are:

(I renamed disk-mount to disk-mount22_04 due to accessing problems due to I killed the process guestmount.)

The copy-commands before the erroneous command worked perfectly.

I googled for similar errors and couldn’t found help. I am new to this project and never used guestmount before. So I think I missed something but cannot tell what.. Can anyone help me, please?
