How to use ramoops with qemu-system-aarch64

[tr4v3ler]

I cannot find anything under /sys/fs/pstore directory after kernel panic. I compile  Linux kernel 5.10 with

following configs:

CONFIG_PSTORE=y

CONFIG_PSTORE_RAM=y

My qemu version is:

QEMU emulator version 6.2.0 (Debian 1:6.2+dfsg-2ubuntu6.15)

The command I used is:

qemu-system-aarch64 \

  -accel tcg \

  -machine virt \

  -cpu cortex-a57 \

  -nographic -smp 8 \

  -drive file=/home/tr4v3ler/data/tools/buildroot-2023.02.8/output/images/rootfs.repro,format=raw \

  -drive file=mydisk.img,format=raw \

  -kernel /home/tr4v3ler/data/src/linux-5.10.y/arch/arm64/boot/Image \

  -append "root=/dev/vda oops=panic panic_on_warn=1 panic=-1 nokaslr debug" \

  -m 8192 \

  -net user,hostfwd=tcp::10023-:22 -net nic
