tools/libxc/xc_private.h the start line is 88. 88 static inline int do_xen_version(int xc_handle, int cmd, void *dest) 89 { 90 DECLARE_HYPERCALL; 91 92 hypercall.op = __HYPERVISOR_xen_version; 93 hypercall.arg[0] = (unsigned long) cmd; 94 hypercall.arg[1] = (unsigned long) dest; 95 96 return do_xen_hypercall(xc_handle, &hypercall); 97 } Ctags can help you find the definition a function. Just run the following commands. cd xen-src-dir ctags -R vim -t do_xen_version then you got it. -- Best Regards Shaohui ________________________________________ From: xen-devel-bounces@xxxxxxxxxxxxxxxxxxx [mailto:xen-devel-bounces@xxxxxxxxxxxxxxxxxxx] On Behalf Of ææå Sent: 2008å3æ7æ 17:46 To: xen-devel Subject: [Xen-devel] where is the location of definition of "do_xen_version"? hi, my friends:  Currently, i am studying theÂway 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-0Âxen-3.1.0-src]#ÂfindÂ./Â-nameÂ"*.*"Â|ÂxargsÂgrepÂ"do_xen_version" ./xen/include/xen/hypercall.h:do_xen_version( BinaryÂfileÂ./xen/common/built_in.oÂmatches BinaryÂfileÂ./xen/common/kernel.oÂmatches ./xen/arch/x86/x86_32/entry.S:ÂÂÂÂÂÂÂÂ.longÂdo_xen_version ./xen/arch/x86/x86_32/entry.S:ÂÂÂÂÂÂÂÂ.byteÂ2Â/*Âdo_xen_versionÂÂÂÂÂÂÂ*/ BinaryÂfileÂ./xen/arch/x86/x86_32/built_in.oÂmatches BinaryÂfileÂ./xen/arch/x86/x86_32/entry.oÂmatches ./xen/arch/x86/x86_64/entry.S:ÂÂÂÂÂÂÂÂ.quadÂdo_xen_version ./xen/arch/x86/x86_64/entry.S:ÂÂÂÂÂÂÂÂ.byteÂ2Â/*Âdo_xen_versionÂÂÂÂÂÂÂ*/ BinaryÂfileÂ./xen/arch/x86/built_in.oÂmatches BinaryÂfileÂ./xen/arch/x86/hvm/hvm.oÂmatches BinaryÂfileÂ./xen/arch/x86/hvm/built_in.oÂmatches ./xen/arch/ia64/linux-xen/entry.S:ÂÂÂÂÂÂdata8Âdo_xen_version ./xen/arch/powerpc/powerpc64/hypercall_table.S:ÂÂÂÂÂÂÂÂ.quadÂdo_xen_version BinaryÂfileÂ./dist/install/boot/xen-syms-3.1.0Âmatches ./tools/libxc/xc_private.c:ÂÂÂÂrcÂ=Âdo_xen_version(xc_handle,Âcmd,Âarg); ./tools/libxc/xc_private.h:staticÂinlineÂintÂdo_xen_version(intÂxc_handle,Âint cmd,ÂvoidÂ*dest)  but the "do_xen_version" is not in those above.  thanks a lots.  www.ict.ac.cn 2008-03-07 ________________________________________ ææå _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
