Hi all. This is a bit peripheral to rtlinux, but hopefully someone here can help me out.
I have written a data acquistion application using an rtlinux module, and, while everything works well when I am not saving data to disk, during disk writes I get pauses in the display. This is, as far as I understand it, a result of disk write buffering, and I'm wondering if there is anything I can do about it. I've tried fflush-ing the file and using setvbuf to set the file to non-buffered mode, but neither of those had any effect on the pauses. During the pauses the cpu usage goes up from about 50% to 100% (most of it dedicated to the system). Is there any way for me to force a larger number of small disk writes so I can minimize the gaps in the display?
