Hello, I have a few questions about seL4's scheduling model in the main (formally verified) branch. 1) I see the time slice parameter in make menuconfig. Is that where I can change the scheduler's time slice correct? And the unit is in timer tick period I suppose? 2) I kind of remember the discussion we had that if an interrupt handler has lower priority than the currently running task, then the interrupt wouldnt happen. So what if both of them have the same priority, would the kernel schedule the currently running task until it uses up all of its timeslice, then issues the interrupt notification or would the interrupting process get executed right away?
