Debug using gdb debugger, how to get the exception level?

Boon Khai over 4 years ago

I'm debugging the ARM Cortex A53 on the QEMU emulator using gdb debugger, any idea on how to get what exception level I'm running on (EL3/2/1/0) ?

HI Bastian,

i'm aware of the CurrentEL register, but somehow I'm not able to print at gdb debugger. The picture showing the result on what I get when i try to print the CurrentEL register, I even try with different combination of capital letter, still not working. I try to dump the register info, not showing anything related to the CurrentEL register.
