Hello. I'm new to kernel development and have some questions.
1. Why can't I divide with regular casting to double ((double)a / (double)b)? It gives me strange errors when compiling: WARNING: "__divdf3" [/root....] undefined! WARNING: "__addf3" [/root/...] undefined! WARNING: "__floatsidf" [/root/...] undefined! And if I compile with normal integers, I get zero as the result. 2. I'm trying to get the percentage of CPU used for a certain task_struct and figured the following formula: (task->utime + task->stime) / jiffies Before calculating I convert all the variables to jiffies. Is this correct? Please help.
