mpc8241/8245 floating point unit

From: Ivan Cheng <hidden>

Hi,

    We are evaluating the mpc8241/8245 on the floating point unit.  For they
are based on the 603e core, there is a hardware floating point support.  And
we are going to cross-compile the kernel and apps in intel platform.  I am
very interested to know

- whether the FPU is supported in the linux distribution in both user/kernel
mode.
- If so, how should I compile for the applicaiton/driver with gcc?
- , and in which version of gcc does it support?

Thanks very much for any comments.

USER Application on IBM 405 based processor using vulcan chip

From: Rakesh Jagota <hidden>

Hi all,
I am working for Settop Box project with IBM405 processor in linux. I am
developing an user application to inetract the user with settop box. I am
using i2c interface for this. I am not able to understand the following
things:
1. Whether we should decode the Transport straem directly or we should store
it first and after that go for decoding and play.

2. How we should store the channel information and How to tune the channel.

3. How to load the DES register.

Can anyone help me out to sort out these issue.

Thanks in advance,

Rakesh

What could possibly be the difference.
2. How we should store the channel information and How to tune the channel.
Is this not in the chip documentation
3. How to load the DES register.
Again read the doc.

And for future reference this list is for the linux kernel on powerpc
chips not for help on mpeg chips.

Also it's not a good idea to reply to a mail that has nothing whatsoever
to do with what you write. Some of us has mail readers that can follow
discussion threads and this gets confusing.


/me so this is what you get when you outsource to India.
