[uclibc-ng-devel] Re: [PATCH] Add time64 support for PowerPC.

PowerPC is big-endian architecture, so there are some significant differences in comparison with time64 support for little-endian architectures like ARM and xtensa.

The main difference is that we strictly need to pass two 64bit values to system calls because Linux Kernel internally uses `struct __ketnel_timespec` and similar, which consists of two 64bit fields. For this reason many files have been changed to convert timespec-family structures (mixed of 64bit and 32bit values) to the 64bit-only structures for using as system calls args. Now time64 syscalls works properly both for LE (ARM, xtensa) and BE (PPC) memory layouts.
