Re: menuconfig FPU question.
Michael:
the gcc compiler is free to choose usage of floating-point without
"-msoft-float" flag being set. I am concerned that in the standard
usage, Linux might save context of floating point or such. This
command would lock the processor.
In short: To insure that floating point is unused, set this flag.
I am still unable to generate a kernel that works. I need to know,
in simple terms, what steps that are not covered by the HOWTO or
the kernel docs.
I am running potato and the system works, but I need to change the
kernel
for some new hardware that I want to use. I also wish to setup kernel
debugging. Any ideas or directions would be most welcomed.
