[linuxsh-dev] stable SH4 environment

[Bryan R. <br...@ix...>]

Hello,

Don't know if anyone on the list remembers me, but I'm back to SH4
after a six month affair with the PPC405. :-)

We are going to be shipping a product including LinuxSH very shortly,
and since a lot has probably changed since I was last involved with the
project, I would really appreciate answers to the following
ever-present questions:

1) What is currently the most stable SH4 kernel version for production
use?

We have had great luck with the 2.4.2 snapshot I got months ago,
but I'd like to get something newer than that without going all the way
to bleeding edge.

2) What is currently the most stable toolchain for building the kernel?
Still the 2.97 version described by Masahiro Abe's instructions?

(I'm a little reluctant to use an experimental compiler for production
stuff, especially on the kernel)

3) What is the status of gcc 3.0, as we will shortly need it for
building user code? (I've heard the kernel and glibc are still
most stable/fast when built with older gcc).

I know kaz Kojima has patches here:
http://dodo.nurs.or.jp/~kkojima/index.html, but
is anyone using them in a real production environment?

4) what is an approximate timeframe for getting binutils and gcc patches
for LinuxSH merged with the mainline GNU trees? My work with Linux
on the PPC405 has led me to think that this should be a _really_ high
priority for all embedded forks of Linux/GNU tools. If my employer
allows, I could be able to spend some time assisting in what ever way
possible.

Thanks! I'm looking forward to working with all of you again.

Regards,

Bryan
