Context Switch Monitoring functionality

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
