I'm working on implementing a higher resolution timer using the x86 TSC. However, this entails 64-bit arithmetic since on a 2GHz machine it will overflow a 32-bit number every couple of seconds (the TSC counter CPU cycles since boot).
So to convert the TSC value into a value in milliseconds, I need to do 64-bit division, but when I try to build GRUB now, I get undefined reference to `__udivdi3' Is this expected? Should it be possible for me to do division on grub_uint64_t types? BTW, I'm trying to add it to the kernel image, if this makes a difference. Thanks, Colin
