Hi all, First, I would like to establish that I'm fairly new to the scheduler portion of kernel code. I'm trying to implement a crude form of the rate limiting approaches described in: Currentcy - http://cseweb.ucsd.edu/~vahdat/papers/usenix03.pdf Pixie - http://www.eecs.harvard.edu/~mdw/papers/pixie-sensys08.pdf My current design is as follows ('task' refers to the current process' task_struct): - I have augmented a hardware simulator(Gem5) with registers that keep track of energy usage. - Upon every call to __schedule(), subtract the register value from 'task->available_energy' - If 'task->available_energy' is negative: - Compute 'replenish_time' as time taken to replenish energy - Call schedule_timeout(msecs_to_jiffies(replenish_time)) - Reset energy registers I'm primarily looking to disallow scheduling of the current task for the period defined as 'replenish_time'. I can see how it might be wrong to call schedule_timeout() from within __schedule(). If so, what would be the right way of designing such a mechanism?
