Bug Description
Hello,
I'm running qemu 2.12 on a raspberry pi 3 with the command:
qemu-system-aarch64 -M raspi3 -serial stdio -kernel executable.bin
On my start file (right in the beginning with the highest EL), the following instructions:
ldr x0 , =19200000
msr CNTFRQ_EL0, x0
and qemu halts on the "msr CNTFRQ_EL0, x0" instruction.
I believe this is not a normal behavior.
Thank you
Mmm, that's not really supposed to happen. Do you have a test guest binary you can attach that I can reproduce with?
