[Qemu-devel] How to extract task excution infomation from qemu

[Sam]

We have been trying to build a multicore NoC emulator, which can runs a full 
system. We plan to run the full system in qemu and get information from 
traces to feed noxim,which is a NoC emulator. Noxim needs to read a taskList 
to start emulating. Each task include the following data fields:

#ExecutionTime          The execution time of this task

#InputTaskID[...]        The predecessors of this task(which must be 
completed before starting this task)

#InputReady[...]        Indicate whether the predecessors are ready. If all 
predecessors are ready, this task can be fired.

#OutputTaskID[...]      The successor tasks(need this task be completed 
first)

#OutputProcessorID[...] The processors holding the successor tasks

#OutputPkgSize[...]     The data size of communication between this task and 
the successor tasks

So we need to extract the following task information from qemu: id of the 
processor  the task runs on, the execution time, the dependency between 
tasks and the data size of communication between tasks.
I've been searching on google for several days and few information has been 
got. Sorry to bother you and thanks very much.
