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.

Hi! Where virt_to_maddr() or __pa() is used, paddr_t is mostly expected rather unsigned long. This may fix random issues in PAE mode. Christoph _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

George has release acked all of these. Otherwise mostly minor updates this time around. Summary: A == acked, M == modified A xen: arm64: Add 8250 earlyprintk support A xen: arm64: Add Basic Platform support for APM X-Gene Storm. A xen: arm64: Add APM implementor id to processor implementers. M xen: arm: add a quirk to handle platforms with unusual GIC layout A xen: arm: allow platform

Biggest change is to switch the new DTB node to /xen-core-devices instead of /xen at Stefano''s request. I also dropped the few patches title HACK etc which weren''t supposed to be there and fixed up some bits and pieces which folks commented on. George, WRT the freeze I think this is functionality which we cannot ship Xen 4.4 without. The impact is entirely constrained to the

Changes from v2 to v3: - Use pfn_to_paddr() to get the address from frame number instead of doing shift directly. - Remove some unnecessary initialization code and add "static" to vmentry_fields and gpdptr_fields. - Enable the VMREAD/VMWRITE bitmap only if nested hvm is enabled. - Use clear_page() to set all 0 to the page instead of memset(). - Use domheap to allocate the

...pping). We had already wrapped most of these in a suitable inline function so it was easy enough to abstract away. Lastly, rather than switch internally from explicitly sized types to unsigned long I have instead introduced some semantic types (register_t and vaddr_t, which complement the existing paddr_t). I''m not really too sure of this approach though. Ian.

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.

This series of patches makes Xen pass a (somewhat) valid device tree to dom0. The device tree for dom0 is the same as the one supplied to Xen except the memory and chosen nodes are adjusted appropriately. We don''t yet make use of the device tree to map MMIO regions or setup interrupts for the guest and we still include the UART used for Xen''s console. Note that loading Linux

I''m afraid this series is rather a grab bag and it is distressingly large at this stage. With this series I can boot an Xgene board until it fails to find its SATA controller. This is a dom0 issue for which patches are pending from APM (/me nudges Anup). As well as the APM specific platform stuff there are also some generic improvements which were either necessary or useful during this

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator.

This patch fixes size of ttbcr register (TCR_EL1 in case of AArch64) and it''s programming considering size in case of context switch. Currently ttbcr is defined as 32b register but for AArch64 TCR_EL1 size is 64b.
