Hi Everyone,
I need to know if there is the same of the Last Branch Recording (LBR) hardware feature of the Intel processors on Arm processors for instruction level monitoring during the life-time of a process with minimal overhead.
Thank you.
Not sure what LBR does, but ARM's ETB records "only" branches instead of a full trace.
Which ARM processors implement it ?
Cortex-A9 for example.Follow: community.arm.com/.../reading-etb-from-software
