Title: floating point emulator for kernel 2.4.18 on Zaurus 5600
Post by: sbarman on March 16, 2004, 11:16:25 am

Since the ARM processor that comes with Zaurus 5600 doesn\'t have any floating point unit, is it possible to install a floating point emulator on 5600 that can be used in the kernel space. This is required by some kernel drivers that we are modifying. If it is possible please let me know the steps.

I think the floating point emulation is in libc (or it might be in libm I suppose).

Do kernel modules link against libc? Otherwise it would probably be easiest to compile the emulation into the module.

P.S. If only the zauruszone forume were still about. I asked about fp emulation a long long time ago while trying to work out how to compile R.

FP emulator is already included in the kernel. AT least there is such an option when compiling the kernel and it\'s on by default
