Hallo, i have one process, which i want to run on a cpu (> CPU0). The special thing here is, that this process is very time critical and should NOT be interrupted by anything (cpusets/cpus_allowed would not be enough). (the process is not doing any system calls and is communicating to the world by shared memory). so i wanted to run the process on a CPU1, when all irqs are disabled and so the process could not be interrupted.
I tried very simple to
(1) migrate all processes to CPU0 by cpu_set_allowed (2) gave my process (running on CPU1) the highest priority (3) run schedule and make sure that the irqs are disables (disable_irqs()) ...
but well, it didnt work ... actually i wanted to ask if this could work and if there is maybe sth like this already somewhere implemented (or easily adaptable). thx patrick
