Context Switch Monitoring functionality

[Choi Wonseok]

Hello. I am graduate student at Korea University studying Intel GPU.

The functionality I need is to find out the 'context identifier' that was
just switched-out when a (or specific) context is switched-in to an engine
(Render Engine etc.).
I'd like to implement such functionality, especially with 'Context
Submission via GuC' enabled. (and I understand that in Proxy Submission
through GuC, guc_id is used as a context identifier instead of Context ID)

Is it possible to monitor context in/out in this way (through kernel
modification + H2G/G2H communication etc.) and, if possible, Could you
provide direction/insight on what elements should be used to implement this?

I'm sorry for asking such a bothersome question. I would really appreciate
it if you could reply.
