2021-05-03 Thread Marco Barletta via Xenomai
Hi everyone; I started to work with xenomai for my master degree thesis and there was a great interest around sched_quota and a possible hierarchical modification of it. Anyway we found there are some theoretical problems around schedulability and feasibility of task scheduled by sched_quota. Did y
