Portal is a device that connect devices. Currently, you can only connect
pipes in portal. Pipes are unidirectional. But with portal, you can
construct a bidirectional device with two pipes.
device/pipe: add nonblocking read/write and force write mode2013-08-19T07:35:56ZGrissiomchaos.proton@gmail.com2013-08-19T07:35:56Zurn: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.
ringbuffer: add put_force and putchar_force API2013-08-19T07:32:42ZGrissiomchaos.proton@gmail.com2013-08-19T03:52:04Zurn:sha1:4919d29d693491e8eae9697deed7b808c7bcbb93
Add the APIs that will discard the old data when rb is full.
ringbuffer: fix the ambiguous name2013-08-19T06:12:35ZGrissiomchaos.proton@gmail.com2013-08-19T02:50:20Zurn:sha1:981d929b562610328309ee4e01d66727f5e6896e
RT_RINGBUFFER_SIZE could mean "the size of the whole buffer", "the size
of the empty space" or "the size of the data". Moreover, it's never a
micro anymore. Change it to rt_ringbuffer_data_len before it's too late.
Also, RT_RINGBUFFER_EMPTY is changed to rt_ringbuffer_space_len.
device/pipe: add rt_pipe_{init,detach}2013-08-19T04:28:59ZGrissiomchaos.proton@gmail.com2013-08-19T04:24:15Zurn: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.

The new implementation use the mirroring method to distinguish full
buffer and the empty buffer. It also support buffers of arbitrary size.
