Reduced Development CycleReduced Development CyclePosted Sep 4, 2002 1:59 UTC (Wed) by mmarq (guest, #2332)In reply to: Reduced Development Cycle by mmarq Parent article: The 2.5 device model More on crazy idea!!! For those that thoughed that I must had been on drugs, here is another dose!!! Since the proposed transferes between a Ethernet board and a graphics or sound board( in the exemple), could be essencialy by nature, a streaming data transfer mode, I not departure even more from I2O V2.0 spec, and use the "facilities" of the STCP(stream protocol)[an alternative could be ST-RTP, another open protocol] now introduced in the 2.5 kernel. Since the real interesting thing about a middle communication layer- apart from isolate device_drivers from the rest of the kernel, is the direct communication between device_drivers wihtout or with minimal interruping of the central CPU, then streaming all possible transfers of data could be a very efective way of achieving this. The use of STCP or alternatives could be the key to use I2O defined "hardware_drivers", whihtout special Mobos or expansion boards with IOP(interrup processores), and with very little overhead - I2O "device-drivers" on plain commodity hardware!!! And since there was the famous kernel in a IBM wristwatch, and since the STCP can propagate even on the INTERNET(some developers think it could replace TCP), this could propel the use of a Linux box not only to use and control it's own devices and peripherals, but also remote devices and peripherals, connected or not to other computers, and including devices like HDTV or HI-FI set!!!...remote now has no limit...Imagine watching and program your home cable HDTV set recording facilities, from a laptop in a hotel, in another continent, connected trough the internet???!!!!
