qemu-6.0.0: Assertion 'p_rcu_reader->depth != 0' failed

[Aileen Honess]

Hi,

 

I’m attempting to run multicore bare-metal tests on the qemu-6.0.0 release, built from the downloaded tar file.  The tests themselves are generated, but are a mix of C and ASM, compiled into an ELF. I’m migrating to the current QEMU release from version 4.1.0 or so.

 

My command line (with or without “-s -S”) is:

 

%> /tools/gnu/qemu-6.0.0/bin/qemu-system-aarch64 \

     -machine virt-6.0,secure=on,virtualization=on,gic-version=3 \

     -s -S \

    -m 1024M \

    -cpu max \

    -smp 4 \

     -nographic \

    -semihosting \

    -bios pssTop.elf \

    -device loader,file=pssTop.elf,addr=0 \

    -device loader,addr=0x40100000,cpu-num=0 \

     -device loader,addr=0x40100000,cpu-num=1 \

     -device loader,addr=0x40100000,cpu-num=2 \

     -device loader,addr=0x40100000,cpu-num=3;

 

This will run and produce expected results (through the UART) for a bit.  The amount of output varies from run to run.

However, it will consistently die with this error, for which I find little help:

 

qemu-system-aarch64: /home/aileen/Downloads/qemu-6.0.0/include/qemu/rcu.h:93: rcu_read_unlock: Assertion `p_rcu_reader->depth != 0' failed.

 

Any ideas…?

 

Thanks!
