[linuxsh-dev] floating point usage in SH4 linux

[Pete L. <pet...@st...>]

Hi all,
I have a question concerning floating point support in the Linux kernel for
SH4 processors.

My situation is this, I am trying to port an x86 driver to an SH4 HARP
board.  The x86 driver makes extensive use of floating point math, which I
know is not supposed to be used in Linux Kernel mode, but I do not have an
alternative approach to avoid making use of floating point.

My question is this, is there a version of kernel, or the tool chain that is
more likely to support the usage of floating point in the kernel?
Alternatively, is it possible to say definitively that floating point math
will or will not work in a kernel mode driver?

Thank you for your time, it is much appreciated,
