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

Boon Khai

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 Vstehle,

    I'm able to dump out the cpsr register, but I don't have the decoded register value like yours in the square bracket, referring to the document you shared, I don't find any bit specifying the Exception Level, only the NZVC APSR, etc...

    Here is my cpsr at EL3 (i guess) 

    And here is my cpsr at EL0 (i guess, because it is now running the baremetal application)
