Re: [tcf-dev] TCF multi core debugging support?

[Eugene Tarassov <eugene.tarassov@xxxxxxxxxx>]

Hi Guenther,

In short, you build the agent with ENABLE_ContextProxy=1, which means you don't want the agent to use native OS debug interface, like ptrace on Linux. You will have to implement low level debug functions, like context_read_mem(), etc. That implementation will map context IDs to cores.

You don't have to change existing services, though you might want to disable services like FileSystem and SysMonitor, because they might not be applicable to multicore debugging.

Regards,
Eugene

Hi Eugene,

I understand that TCF is not a fully multicore debugger. However what needs
to be taken into account for building such one?
Would it be correct to add a core# specifier to the ContextID for each
service command? And/or would I need to re-implement all existing services
for multi core?

Thanks,
Guenther

Hi Guenther,

I'm not sure what aspect of multicore debugging you mean.
If you are looking for a ready-to-use multicore debugger, TCF is not that.
It is a framework that provides most of the modules needed to build such
debugger.
There are commercial multicore debuggers built using TCF.

Eugene

Hi All,

How is TCF multi core debugging intended to be working? I found no code in
the TCF agent regarding multi core debugging.

Thanks,
Guenther
