Hi all, this patch series makes the necessary changes to make sure that the current ARM hypercall ABI can be used as-is on 64 bit ARM platforms: - it defines xen_ulong_t as uint64_t on ARM; - it introduces a new macro to handle guest pointers, called XEN_GUEST_HANDLE_PARAM (that has size 4 bytes on aarch and is going to have size 8 bytes on aarch64); - it replaces all the occurrences of

Populate-on-demand: Check pages being returned by the balloon driver This patch series is the second result of my work last summer on decreasing fragmentation of superpages in a guests'' p2m when using populate-on-demand. This patch series is against 4.1; I''m posting it to get feedback on the viability of getting a ported version of this patch into 4.2. As with the previous

Hi, Olaf we have tested the xenpaging feature and found some problems. (1) the test case like this : when we start a VM with POD enable, the xenpaging is started at the same time. this case will cause many problems ,finally, we fixed the BUG, the patch is attached below. (2) there is a very serious problem. we have observed many VM crash examples, the error code is not always the same.

A number of build problems crept in once again. Fix them.

This series implements ballooning for Xen on ARM and builds and Mukesh''s PVH privcmd stuff to implement foreign page mapping on ARM, replacing the old "HACK: initial (very hacky) XENMAPSPACE_gmfn_foreign" patch. The baseline is a bit complex, it is basically Stefano''s xenarm-forlinus branch (commit bbd6eb29214e) merged with Konrad''s linux-next-pvh branch

We use XENMEM_add_to_physmap_range which is the preferred interface for foreign mappings.

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

This patch series restores the use of superpages when restoring or migrating a VM, while retaining efficient batching of 4k pages when superpages are not appropriate or available.

The following two patches are about how to speed up in xenpaging when page in pages. On suse11-64 with 4G memory,if we page out 2G pages,it will cost about 15.5 seconds, but take 2088 seconds to finish paging in.If page-in costs too much time,it will cause unmesurable problems when vm or dom0 access the paged_out page,such as BSOD,crash. What鈥檚 more,the dom0 is always in high I/O pressure.

There has been some progress, but still no joy. Definitely not intended for inclusion at this point. Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table sharing. Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit hypervisor and Win 7 guest). Hongkaixing, I incorporated your suggestion in patch 2, so I should add your Signed-off-by eventually.

The following two patches allow the parallel use of memsharing, xenpaging and xen-access by using an independent ring buffer for each feature. Please review. v2: - update mem_event_check_ring arguments, check domain rather than domain_id - check ring_full first because its value was just evaluated - check if ring buffer is initialized before calling mem_access_domctl/mem_paging_domctl

This patch series includes a series of bugs related to p2m, ept, and PoD code which were found as part of our XenServer product testing. Each of these fixes actual bugs, and the 3.4-based version of the patch has been tested thoroughly. (There may be bugs in porting the patches, but most of them are simple enough as to make it unlikely.) Each patch is conceptually independent, so they can each

ging_prep ensures that an mfn is backing the paged-out gfn, and transitions to the next state in the paging state machine for this page. Foreign mappings of the gfn will now succeed. This is the key idea, as it allows the pager to now map the gfn and fill in its contents. Unfortunately, it also allows any other foreign mapper to map the gfn and read its contents. This is particularly dangerous

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

I ran a bisect to find out when Windows XP 32 bit becomes unusably slow. And I found the changeset that caused it. ========== The problem: ========== Windows 8 64 bit and 32 bit run fast and fine in the newest xen versions. Windows XP 32 bit runs unusably slow in anything new that I built from xen-unstable, but runs fast in 4.1.2 and 4.1.3 stable. While it is running slow, "xm top" or

I''ve encountered a rather unusual bug while I''m implementing live migration on arndale board. After resume, domU kernel starts invoking hypercalls and at some point the hypercall parameters delivered to xen are corrupted. After some debugging (with the help of HW debugger), I found that cache polution happens, and here is the detailed sequence. 1) DomU kernel allocates a local
