Hi, Regarding Realtime patches, I was successfully able to patch it on normal linux kernel, but was not successful when I integrate it with Android kernel. I was able to patch and compile it, but am facing while loading the android system. I get some errors while loading real time modules.
Regarding real time support in android, basically most of them are concentrating on Application base of Android, but as Android uses regular kernel, where it gives average performance and its not optimized for real time, we might see some performance issues on Android. Practically I have not checked any hand held devices which uses this Android and how it performs, but if Android kernel can be made real time to some extent, then we can atleast see better performance right? "It will reduce overall system performance, and you still have hardware latency problems that can cause issues that are outside of the Linux kernel's control. What are you trying to do here?" --> for this question, I did not get how it will reduce overall system performance? Can you give me some clues? Whats my thinking is, if we can optimize android kernel for real time performance, then over all system performance will improve which can make android a better system/product. Any comments are welcome?
