linuxval means linux virtual abstract layer. By this , people can port ucos-ii , freertos , etc. to linuxbox easily. In linuxval SingleThread version, all tasks use one thread together and tasks can switch in this thread by linux *context functions. RTOS can look at linux as a spcecial machine by linuxval. Now,linuxval can support task context switches and has a time interrupt. linuxval makes it more abstract and more modular when we port RTOS to linuxbox and all lowest function can be achieved by C language instead of ASM. So it is a good helper when you are studying or debuging a RTOS.
Now, i have port uCOS-II and FreeRTOS to linuxbox by linuxval and add some simple examples.
