similar to: Why using hypercall_page ?

Hypercall_page is actually a code page, which contains 32 hypercall entry. every entry is something like "mov $__HYPERVISOR_xxx,%eax int $0x82 " It is initialized in hypercall_page_initialise(void *hypercall_page) at the time when control panel creates the domain. Later, domain can simply the corresponding entry to issue a hypercall. For the subroutine of the HYPERVISOR_xxx,

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 all, Can Xen hypervisor modify HVM domU's Shadow page table, under the dom0's context, like trapped from dom0's hypercall? I think it have to call 2 functions at least: guest_walk_tables() and flush_tlb_all(). Can these 2 functions called in dom0's context? In my test, if hypervisor tries to modify HVM's shadow page table, it will bring down the whole system. I am not

Hi men, When installing Xen, it builds a linux guest kernel of 2.6.18 as dom0, which does not support my network card. While 2.6.27 supports my card. So what should I do now?

Hi, after solving the issue I had with a DVB tuner I tested again suspending and resuming from S3. I am now running Xen 4.2.0 and have applied patches [1] and [2] (any idea why they are still not in mainline?) over a 3.5.3 kernel. I only tried once since I upgraded my Xen, but after resuming I got the following back trace: [ 142.267299] pcieport 0000:00:1c.5: wake-up capability enabled by ACPI

hi! I'm studing samba as PDC (with ldap backend) and I would know: - gid and uid are useful in samba? in other words: if pdc admin knows users' uids, he can recovery some wrong situations ? Example: if a user was cancelled and then readded, if his uid changes implies some troubles with shared files? NT mantains, after deletion, association between shared file and uid user and so if

Hi, I''m trying to use the SYSCALL/SYSRET opcodes with a minios kernel without much success. Going by the manuals (and linux sources) I first have to setup the STAR and LSTAR registers to define the segment and instruction pointer to be used for SYSCALL: /* * LSTAR and STAR live in a bit strange symbiosis. * They both write to the same internal register. STAR allows

Hi I need to use hypercalls from HVM domain (e.g. HYPERVISOR_add_to_physmap). However, it does not work when I am trying to invoke it from HVM Linux guest. Basically, I don''t see that anything happens on hypervisor''s side. I also grep''ed the guest code for ''vmmcall''/''vmcall'' and did not find anything. Is it possible to do it at all?

Hi Users, Administrators and Pavel Jezek, You prefer chan_h323 from asterisk tree and it's of course that use channels by tree is very good.

Hi, I try to make an analyses to discover what is the time that an area begin to have spacial autocorrelation. And after, what is the number of individuals responsible for this autocorrelation. The main idea is to discover if exist a contamination of a quadrat from others quadrats and how is the population needed to make this contamination. This is very common to use automata to simulate

I am working on some other bugs and perf issues - and while working I noticed that both sparse and Coverity have reported some issues with Xen drivers. Please see attached various bug-fixes that I am proposing for 3.6.

This group of patches removes all DPRINT from hv_vmbus.ko. It is divided in several patches due to size. All DPRINT calls have been removed, and where needed have been replaced with pr_XX native calls. Many debug DPRINT calls have been removed outright. The amount of clutter this driver prints has been significantly reduced. Signed-off-by: Hank Janssen <hjanssen at microsoft.com>

Xen i386 xen-head.S fix sections mixup xen-head.S does not come back to the data section, leaving the text section as current section. It causes problems with a slightly enhanced DEBUG_RODATA that supports CONFIG_HOTPLUG and bringing a CPU up after the text has been marked read-only: reference to early_gdt_descr causes a page fault. It applies on 2.6.22-rc2-mm2. Signed-off-by: Mathieu Desnoyers
