[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] 2 questions about hypercall
Hi, I've been reading the xen source code recently, and I have got 2 questions about hypercall. 1. I find 2 header files named hypercall.h in the directory linux/arch/x86/include. One is in the sub-directory /mach-xen/asm/hypercall.h, and the other is /asm/xen/hypercall.h. After comparing these two, I find their contents are similar but different, and I can't figure out what's the difference between them, what their purposes are , and when kernel want to trap into xen hypervisor, which one will kernel chooseï 2. I find that the xen tools also used hypercall. My question is how does tools used it ? is the process the same as the kernel, or xen tools use hypercall in a different way? -- View this message in context: http://xen.1045712.n5.nabble.com/2-questions-about-hypercall-tp5024421p5024421.html Sent from the Xen - Dev mailing list archive at Nabble.com. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
