rocgdb uses a driver that provides an ioctl interface that is similar in concept to what the ptrace and waitpid do for a CPU. There is a Debugger API library that uses the ioctl interface to provide an general way to control the GPU threads. There is a rocm target that is part of gdb that uses the Debugger ABI to allow GPU threads to be controlled just like CPU threads. All the code is open source.

Thanks,

[CAUTION: External Email]

Hi ,

In a heterogenous environment , how ROCm / rocgdb pass its debug commands ( example : breakpoint command) to the target ( Example a GPU) . Does the debugger queue it’s debug commands using HSA queues ? If that’s not that case how ?

What is the role of the driver in this case .

Thanks
