Bright Pan 2d67fe6565 [Driver/ringbuffer]: Fix put_force bug
OXape reports: http://www.rt-thread.org/phpBB3/topic3939.html
          driver/ringbuffer: when data length is bigger than space length
          for rb, the read_index in rb is not update.
    When length > space, update the read_index, the bug can be fix, and
          works fine.

Grissiom 0feefc03b6 device/pipe: add a control cmd to get the space left in pipe 2013-10-23 01:43:18 +08:00
Grissiom 246bdde8de dev/portal: fix bug in portal callback forwarding
When forwarding rx/tx callback from the underlaying device(pipe), the
"dev" argument should be the portal. So the portal callback could think
itself as called.

Grissiom 824261d3bc dev/portal: add checks on oflag
It does not make sense to open portal without a flag. One should open a
portal with RT_DEVICE_OFLAG_RDWR in most cases.
2013-08-22 15:12:00 +08:00
Grissiom 6e676e7754 dev/portal: implement portal device
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.

Grissiom 7e68096a88 dev/pipe: make pipe a type of device
Pipe have many differences with char device. The main difference is
altough pipe have both read and write, it is unidirectional in nature.

Grissiom e8cca2315a dev/pipe: call rx_indicate the time we resume reader
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.
2013-08-19 15:57:59 +08:00
Grissiom d683d32bd5 device/pipe: add nonblocking read/write and force write mode
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.

Grissiom 4919d29d69 ringbuffer: add put_force and putchar_force API
Add the APIs that will discard the old data when rb is full.

Grissiom 981d929b56 ringbuffer: fix the ambiguous name
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.
2013-08-19 14:12:35 +08:00
Grissiom 38ce3879d8 device/pipe: add rt_pipe_{init,detach}
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.

Grissiom 639bd30321 reimplement ringbuffer
The new implementation use the mirroring method to distinguish full
buffer and the empty buffer. It also support buffers of arbitrary size.
