Hi! Attached patch removes gfn_to_mfn_current(). It is redundant and effectively unused. All remaining users now use proper replacement function. => No functional change. While here, silence stdvga and use page_mode_hap() consequently.

Hi Tim, Could you please have a look at this bug? Thanks a lot. http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1774 Best Regards, Yongjie Ren (Jay) _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

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.

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.

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

There are BIOSes that want to map the IO-APIC MMIO region from some ACPI method(s), and there is at least one BIOS flavor that wants to use this mapping to clear an RTE''s mask bit. While we can''t allow the latter, we can permit reads and simply drop write attempts, leveraging the already existing infrastructure introduced for dealing with AMD IOMMUs'' representation as

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

Patrick, there following patches fix xenpaging for me. Granttable handling is incomplete. If a page is gone, a GNTST_eagain should be returned to the caller to inidcate the hypercall has to be retried after a while, until the page is available again. Please review.

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.
