- codys 7y agoIt is trying to make the linux kernel more real time capable. Having periods of time where preemption isn't enabled (due to having interrupts disabled, etc) results in more variation in when tasks are scheduled, including real time tasks. The reality is that "real time" as a definition covers many "features" and design choices because many ducks need to be in a row for real time tasks to run properly. Decreasing variation in the scheduling of (real time) tasks is one of those items. As a result, it's entirely reasonable to call "linux-rt" "linux-rt".
