While looking at the origin of very frequently executed hypercalls (as usual, kernel builds are what''s being measured), I realized that the high page accessor functions in Linux would be good candidates to handle in the hypervisor - clearing or copying to/from a high page is a pretty frequent operation (provided there''s enough memory). However, the measured results

Hi, V6: The only change from V5 is in patch #6: - changed comment to reflect autoxlate - removed a redundant ASSERT - reworked logic a bit so that get_page_from_gfn() is called with NULL for p2m type as before. arm has ASSERT wanting it to be NULL. Tim: patch 4 needs your approval. Daniel: patch 5 needs your approval. These patches implement PVH dom0. Patches 1 and 2

First off, Apologies for the massive patch series... This series boots a 32-bit dom0 kernel to a command prompt on an ARMv8 (AArch64) model. The kernel is the same one as I am currently using with the 32 bit hypervisor I haven''t yet tried starting a guest or anything super advanced like that ;-). Also there is not real support for 64-bit domains at all, although in one or two places I

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

I'm trying to set up cross-subnet browsing using Samba on a Linux box and a Sparc UltraEnterprise with Win95 and NT Workstation clients. I'm using the Sparc as the domain master and also as the WINS server on the 108 subnet. The Linux box is the local master on the 46 subnet. Both are running Samba 1.9.17alpha4. I can see the conversation between the two samba servers and the browse

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.

hi, what''s the best way (if at all) to iterate through all of a domain''s page tables within xen 2.0.6? i need to find all references to a specific pte value (which is a given). essentially, a reverse page-table lookup. i''m hesitant to switch to 3.0, but if it''s easier to do what i want, just let me know. thanks, -A. -- Aaron Marks Distributed Systems Lab

Add hypercall (shadow op: enable/disable and clean/peek dirtied page bitmap). It consists of two parts: dirty page detecting and saving. For detecting, we setup the guest p2m''s leaf PTE read-only and whenever the guest tries to write something, permission fault happens and traps into xen. The permission-faulted GPA should be saved for the toolstack (when it wants to see which pages

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

From: Zhang Xiantao <xiantao.zhang@intel.com> With virtual EPT support, L1 hyerpvisor can use EPT hardware for L2 guest''s memory virtualization. In this way, L2 guest''s performance can be improved sharply. According to our testing, some benchmarks can show > 5x performance gain.

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, Can anybody shed light on the Xen function map_domain_page (in xen/arch/x86/x86_32/domain_page.c)? What is it doing? Jinpeng Wei _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, I am trying to release domU pages from page_list and xenpage_list after domU shutdown while retaining the rest of the domain information. To achieve this in __domain_finalise_shutdown i call domain_relinquish_resources. This is failing to release pages from page_list for type PGT_l2_page_tables and crashing dom0. To be specific, while testing on mini-os i saw that when

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.

I run an IPsec/Freeswan VPN to connect 4 disparet windows LANS. I managed to RTFM until cross-subnet browsing worked (samba 2.0). Having upgraded to 2.2.3 It would seem that this feature is not working. BACKGROUND: originally all sources of information led me to understand that I would need a box running samba behind the firewall/IPsec box as I could not even ping a remote internal IP from the
