Hi!
I wanted to ask for help on the Foundation model which becomes really slow after a while, to the point where it is not usable anymore. Quite often I have to kill the model (Ctrl-C) and restart it, with corrupted files on the root FS.
I am using the latest Foundation model, kernel image, instructions from the release page [1] but it also happens with my own mainline kernel.
[1] http://releases.linaro.org/latest/openembedded/aarch64/
Symptoms and observations: - after a few minutes the system looks like it is hanging but still reacts on ping, the shell is still active but everything related to the filesystem hangs (top, free, compiler etc.), - there is no sign of memory exhaustion or abnormal caching as seen from a recurrent 'free'. 90% of the memory is free, - the problem arrives faster when working in an NFS mounted dir, - on the visualization webpage (localhost:2001) all cores are idle all the time and the number of instructions executed is really low (about 30K insts/s), - the exact same setup used to work fine until my machine crashed (lost the home dir completely), now the problems happens with both AXF and UEFI based boot.
Is there something you already observed, is there a cure (kernel or root FS config etc.)?
Here is the startup script: # cat boot_fvp_uefi.sh #!/bin/sh
# Start Foundation model >= 5206 from the Image and img images pidof Foundation_v8 > /dev/null && echo -n 'Foundation_v8 already running' && exit
IMAGE=vexpress64-openembedded_lamp-armv8-gcc-4.8_20140417-630.img
exec Foundation_v8 \ --cores=2 \ --network bridged \ --block-device $IMAGE \ --no-secure-memory \ --visualization \ --gicv3 \ --data=bl1.bin@0x0 \ --data=uefi_fvp-base.bin@0x8000000
Any feedback welcome!
Cheers, Jean
