When I compiled my kernel today I noticed:
INSTALL vdso32-int80.so
INSTALL vdso32-sysenter.so
It seemed like a userspace dynamic library. What are these *.so files
doing in the /lib/modules/vdso directory? What are their purpose?
vDSO - short name for ???. I have been reading everywhere but cannot
understand this.
It is architecture specific - why only powerpc and x86 implemented this
feature, how about other arch?
vDSO is enabled or disabled via initialization parameter, vdso=, so what
happened if it is enabled or disabled?
I read this article:
http://lwn.net/Articles/190139/
and don't quite understand the relationship between ld.so and vDSO?
THank you for the education.....
