add aciodrv-proc module
explanation : PANB works differently from other acio devices ; you send
one "start auto input" command without expecting a reply, and then the
piano keeps spamming "recv poll" commands on the acio bus and never replies
to any other commands.. failure to process these messages quickly enough
will saturate the serial buffer and cause checksum errors after a while.
for this reason, aciodrv-proc module was added in order to create a
thread which manages these recv poll commands and keeps the latest
known button state in memory so that it can be retrieved easily.
Tested with:
aciotest / eamiotest:
- DDR Slotted: Node 1: type 3, flag 0, version 1.1.0, product ICCA, build date: Oct 26 2005 13:55:03
- DDR Slotted: Node 2: type 3, flag 0, version 1.1.0, product ICCA, build date: Oct 26 2005 13:55:03
(tested with just 1, as well as a pair)
aciotest / eamiotest / IIDX10,12,27:
- IIDX Wavepass: Node 1: type 3, flag 0, version 1.5.1, product ICCB, build date: Apr 12 2010 09:29:00
- IIDX Wavepass: Node 2: type 3, flag 0, version 1.5.1, product ICCB, build date: Apr 12 2010 09:29:00
(IIDX13 errors on card-in, probably issue with how eamio is being used as previously eamio-icca had no use on it)
aciotest / eamiotest / sdvx1-5:
- SDVX Wavepass: Node 1: type 3, flag 0, version 1.5.1, product ICCB, build date: Apr 12 2010 09:29:00
aciotest:
- Jubeat Wavepass: Node 1: type 3, flag 0, version 1.7.3, product ICCC, build date: Oct 05 2012 20:26:53
- Museca Wavepass: Node 2: type 3, flag 0, version 1.7.4, product ICCC, build date: Feb 27 2013 16:44:51
The single byte is a specific parameter required to initialize
the IO correctly. Otherwise, it either will only work partially
or not worked at all. The full impact and meaning of that byte
is not entirely known, yet.
