hi all, forgive me for my stupid questions.. does anyone can mention some items that differ an rt system that built together with a general-purpose host OS (like rtlinux, rtai) with a dedicated rtos (like qnx, vxworks, spring, maruti, yartos), in case that now: - some dedicated rtos can implement a posix compliant environment and they built their own services (file system, networking, gui) from scratch - some of them also used microkernel approach that separate interupt-processing, scheduling, and message-passing development from other services more of them, they used 'the safe' MMU memory-protecting mechanism that can't be found at rtlinux or rtai realtime module-task and also, I've heard that qnx services except of the microkernel is stayed at user-space (user-level file-system, drivers) , how could they do that.. thanks beforeward for your kindness.. -=/Handy Madinata\=- ----- End of forwarded message from [EMAIL PROTECTED] ----- -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] -- For more information on Real-Time Linux see: http://www.rtlinux.org/
