Hi I am a new cfs learner and am using basecamp for learning, and have a simple question with https://openmissionstack.com/learn_read/why_not_cfs. It is said that the framework is not suitable for multi-core processors, but in the process of using a multi-core operating system (as rt-linux), the software actually does not know the arch of processor, the api used is the same as in single core, the scheduling is handled by the OS, so is there still a problem in using cfs framework?

Apologies for the delayed response, I had an email misconfiguration...

'Not suitable' is a misleading statement and thanks for bringing it to our attention so we can enhance the article. Multiple projects are using the cFS on multi-core processors, however, it is up to the developers to create their own strategy. The intent of the statement is that multi-core support is not built-in to the architecture and deployment tools. Here's one cFS discussion 427 on this topic that may be helpful. I did not do an exhaustive search so there may be others.
