Hello L4-hackers ,
I'm writing a Genode component which should access and modify the Run queues of the scheduler.
Based on what I have read and looked there will be one scheduler for each processor. How to access the different scheduler objects and Run queues from Genode side?
I have looked through the code and able to print the run queue from the ready_queue_fp.cpp.
But how do you access 2 run queues when number of processors is more than one?
And what is the easy way to manipulate these from Genode component.?
PS: I have read Genode book and have a basic idea of Genode architecture.
Best regards, Guru

On Fiasco's API level there is no interface to directly access the run queues of processors. The current interface allows to place a thread on a CPU (plus scheduling parameters) and thus add it to one CPU and remove it from another (or initially launch a thread). CPU selection is done using the supplied CPU mask.
