[Xen-devel] where is the location of definition of "do_xen_version"?

["房海峰" <fanghaifeng@xxxxxxxxxx>]

hi, my friends:

 

Currently, i am studying the way of hypercall's implementation.

i have already known the flow of hypercall's execuation, and i decided to add a new hypercall into the Xen.

first, i want to know the detail of one hypercall function, for example, "do_xen_version", but i can not find

the location of definition of "do_xen_version". who can help me?

 

i have get some resualts as follows:

 

[root@vt-0 xen-3.1.0-src]# find ./ -name "*.*" | xargs grep "do_xen_version"

./xen/include/xen/hypercall.h:do_xen_version(

Binary file ./xen/common/built_in.o matches

Binary file ./xen/common/kernel.o matches

./xen/arch/x86/x86_32/entry.S:        .long do_xen_version

./xen/arch/x86/x86_32/entry.S:        .byte 2 /* do_xen_version       */

Binary file ./xen/arch/x86/x86_32/built_in.o matches

Binary file ./xen/arch/x86/x86_32/entry.o matches

./xen/arch/x86/x86_64/entry.S:        .quad do_xen_version

./xen/arch/x86/x86_64/entry.S:        .byte 2 /* do_xen_version       */

Binary file ./xen/arch/x86/built_in.o matches

Binary file ./xen/arch/x86/hvm/hvm.o matches

Binary file ./xen/arch/x86/hvm/built_in.o matches

./xen/arch/ia64/linux-xen/entry.S:      data8 do_xen_version

./xen/arch/powerpc/powerpc64/hypercall_table.S:        .quad do_xen_version

Binary file ./dist/install/boot/xen-syms-3.1.0 matches

./tools/libxc/xc_private.c:    rc = do_xen_version(xc_handle, cmd, arg);

./tools/libxc/xc_private.h:static inline int do_xen_version(int xc_handle, int cmd, void *dest)

 

but the "do_xen_version" is not in those above.

 

thanks a lots.
