similar to: Where is the xc_translate_foreign_address~~~

I am shame to say that I have never met a function whose return value is void*. This is the first time~~~ So, can anyone told me the meaning of the return value of this function -----xc_map_foreign_range? Is it a pointer pointed to a memory area corresponding the machine frame number(the last parameter passed to the function)? And the third parameter named size: the unit of size is in bytes or

Hello~~~~ I have to use some special functions provided by xen, such as xc_vcpu_getcontext(),xc_map_foreign_range() and so on. I tried to find them in the Xen Interface Manuel, but failed. Does anyone know where they are? And another problem: In the Xen Interface Manuel(Appendix A), "xen/include/public/" has been mentioned many times.But I havn't found such a directory in my

Hi all, I am receiving an error on a VT HVM, which appears to be located in the function xc_translate_foreign_address. Running the xenctx tool on a VT HVM (xen-testing 3.0.2) it returns: # ./xenctx -f 1 eip: c027b646 esp: c0441ed4 eax: 000000c4 ebx: c0495300 ecx: 000001f7 edx: 000001f7 esi: c0495394 edi: 00000000 ebp: c027fec0 cs: 00000060 ds: 0000007b fs: 00000000 gs:

Hi, I looked at the function xc_translate_foreign_address(), and see that it walks the page table of the guest VM. So at best, it should return the pfn of the guest (?) We can see taht the Later part of the function is like this: ... if (pt_levels >= 3) mfn = (pte & L0_PAGETABLE_MASK_PAE) >> PAGE_SHIFT; else mfn = (pte & L0_PAGETABLE_MASK)

Hello~~~ I need to use some functions provided by xen, such as xc_vcpu_getcontext(), xc_map_foreign_ranger() and so on. I have find them in the /libxc/xc_domain.c~~~ But I don't know how to use them in my program. For example, if I need to use the function named printf(), I have to include the header file <stdio.h>~~~ Now, I want to use these functions provided by xen, which header

Greetings, I have a technical question about update_va_mapping_otherdomain....... I have two components: a C program linked against libxc and a kernel module which performs the following simple sequence of events from domain zero: 1. Pause guest (unprivileged) 2. Grabs the PTE associated with a random (but present) page within the guest''s kernel''s address space (using a

Hi: I wanna write code about sharing memory between dom0 and domU, and I decide to use void *xc_map_foreign_range(int xc_handle, unint32_t dom, int size, int port, unsigned long mfn) (this is a function in xenctl.h). My question is : If I wanna map a range of memory in dom0 to domU, how can I　get the value of mfn? and I do not know the port here. Can anybody help me ? Thanks .

The following dump-core patches changes its format into ELF, adds PFN-GMFN table, HVM support, and adds experimental IA64 support. - ELF format Program header and note section are adopted. - HVM domain support To know the memory area to dump, XENMEM_set_memory_map is added. XENMEM_memory_map hypercall is for current domain, so new one is created. and hvm domain builder tell xen its
