In days gone by, once you installed RTLinux you had insmod your modules. Also, it was a good idea to run two separate kernels - a real time and a non real time. These days you initiate a module by typing "rtlinux start <module>". My question is: Is it practicable/recommended to run only one kernel now? Since there is a very clear distinction between the loading of real time and non real time modules is it safe to run the real time kernel in day to day tasks. This would be convenient for me as I use the nvidia driver for my graphics card and I can't get it to work with both kernels simultaneously. Thanks in advance.
