I''m tinkering with some code to be able to talk to the hypervisor from Windows, with the ultimate aim to get a usable xenbus. So far I''ve created a driver for the Xen PCI ''device'', and (hopefully) mapped the hypercall space given by the CPUID call... What is the simplest hypercall I can make to get an answer from the hypervisor to tell me that it''s

...ng from calls INT 113 directly. It would probably be cleaner to do this through a library call that automatically called the x86 emulator on other architectures. I'm able to compile with klibc now. Next I need to make sure everything works. static int vm86_rep(struct vm86_struct *ptr) { int __res; __asm__ __volatile__("int $0x80\n":"=a"(__res):"a"((int) 113), "b"((struct vm86_struct *) ptr)); if ((__res) < 0) { errno = -__res; __res = -1; } else errno = 0; return __res; } ===== Jon Smirl jonsmirl@yahoo.com ___________________________...

I am learning xen's memory management recently. I find most docs is how to use the hypercall related memory management. Can somesome tell me where is the implementation of the them in the xen source. Or some docs explaining it will be ideal. 年少不惧江湖老，放歌四海任逍遥。未解前路多少事，欲与青天试比高。 _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org

Hi. This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. Changes from take 5 are rebased to Linux 2.6.26-rc3, bug fix ivt.S paravirtualization and multi entry point support. I believe these patches can be applied to the linux ia64 repository. This patchset does the followings. - Some preparation work. Mainly importing header files to

Hi. This patchset is ia64/xen domU patch take 8 which was updated following Tony's review. (Thank you very much, Tony.) This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. This patchset is for linux ia64 test branch and depends on some patches for xen common part I'll send separately. To compile, the changesets in x86/xen
