The main difference is altough pipe have both read and write, it is unidirectional in nature. dev/pipe: cleanup 2013-08-19T08:25:17Z Grissiom chaos.proton@gmail.com 2013-08-19T08:25:17Z urn:sha1:0340300f89a924b30fd8042b76686a236720d3d7 dev/pipe: call rx_indicate the time we resume reader 2013-08-19T07:57:59Z Grissiom chaos.proton@gmail.com 2013-08-19T07:57:59Z urn:sha1:e8cca2315a790d61c743a71e1a682e6ace7866fd Some reader(FinSh again) would like to block on a semaphore which is released in rx_indicate. So we should invoke rx_indicate in _rt_pipe_resume_reader. device/pipe: add nonblocking read/write and force write mode 2013-08-19T07:35:56Z Grissiom chaos.proton@gmail.com 2013-08-19T07:35:56Z urn:sha1:d683d32bd5502c15be600145966400a41710a7f4 The previous implementation will always blocks the reader/writer. However, at least FinSh would expect the device to be nonblocking --- read should return 0 when there is no data in it. device/pipe: add rt_pipe_{init,detach} 2013-08-19T04:28:59Z Grissiom chaos.proton@gmail.com 2013-08-19T04:24:15Z urn:sha1:38ce3879d8a98827338696e0b326ba6f6b1749f7 This provide the possibility that allocate the buffer of the ringbuffer on a specific region, instead of always mallocing it. It also bring us the benefit of using pipe device on the systems without heap.
