PRUSS is programmable RISC core which can be used to implement Soft IPs (eg:- DMA, CAN, UART,SmartCard) and Industrial communications data link layers (eg:- PROFIBUS). UIO driver exposes PRUSS resources like memory and interrupts to user space application.PRUSS UIO application API can be used to control PRUs in PRUSS, setup PRU INTC, load firmware to PRUs and implement IPC between Host processor and PRUs. More information on PRUSS and UIO linux user space API available in the links below http://processors.wiki.ti.com/index.php/Programmable_Realtime_Unit_Subsystem http://processors.wiki.ti.com/index.php/PRU_Linux_Application_Loader http://processors.wiki.ti.com/index.php/PRU_Linux_Application_Loader_API_Guide PRUSS UIO driver support patch applies on top of Linus's tree latest. Both patches applies on top of linux-davinci tree latest.
