I am (finally) starting to look at enabling the GLIBC side of VDSO for PPC/PPC64 but have some questions about the details. It looks like I need to define NEED_DL_SYSINFO in dl-sysdep.h to set up the basic processing of AT_SYSINFO and AT_SYSINFO_EHDR. But looking at the i386 and ia64 examples it is not obvious what is needed for the general concept and what is specific to those platforms. For example I don't think PPC needs USE_DL_SYSINFO, DL_SYSINFO_DEFAULT, or DL_SYSINFO_IMPLEMENTATION because we are not changing the syscall mechanism for powerpc. Am I missing something? Also there does not seem to be any kernel_feature specific enable for VDSO. So can I assume that a NEED_DL_SYSINFO GLIBC can run safely on a none VDSO kernel? Steven J.
