Hello all,

We at A&D have been porting RTLinux 3.0 to Linux-sh, especially to SH4.
We think it's ready for review by wider audience, and put patches and
documents at the following place.

<ftp://ftp.aandd.co.jp/pub/linuxsh/rtlinux/current/>

Please read "README_..." file in the directory for instruction.

They are provided "as is", and "WITHOUT ANY WARRANTY", but we welcome
your comments, suggestions, bug reports and alike. We can't assure you
to respond to everything but we will do what we can.

At this time, we would like to show our appreciation to the efforts put
into Linux-sh and RTLinux projects by many people. Especially Mr.
Nobuhiro Sakawa provided us great help. We couldn't achieve this state
without YOU ALL. Thanks everybody!

For those of you interested, here is the summary of status:

- based on Linux kernel 2.4.4 + Open RTLinux 3.0
- measured interrupt latency < 60usec, RTTask startup jitter < +/-70usec
  (we don't guarantee these numbers, you know)
- Basic modules(rtl, rtl_time, rtl_sched, rtl_posixio, rtl_fifo)
  functioning without noticeable problem
- Math with FPU within RTTask supported
- mbuff may not be working properly? needs further investigation
- psc and rtl_tracer can be built but not verified
- rtl_debug not ported (yet)
- works on SH4(7750S). Not yet on SH3?

As I said, we welcome your comments.
