The patch moves the struct IO_APIC_route_entry to a common place. This allows us to share the struct with iosapic. Thanks, -- Dexuan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I tried latest xen and linux-xen staging tree, but failed to run HVM domain on x86-64 environment. domU creation is OK. However the weird thing is not HVM domain itself. Instead system crashed on dom0 context. I saw once with some stack dump that xen''s page fault handler is executed on a dom0''s stack which then causes nested page fault due to unable to fetch vcpu pointer.

The Xen platform device (introduced in changeset 11161) would cause HCT''s PCI Compliance Test to generate a failure message. The patch fixes this.

Changeset 15046:e527b4ff1948 breaks 32-bit HVM guest: when req->size is 4, "1UL << 32" returns 1 in IA32 system, so the mask becomes 0 wrongly.

I think we need this feature at least for debugging purpose, right? Or, do we already have this feature?

Hi, all, The attached patches try to improve the current FLR logic. The idea is: removing the FLR logic from hypervisor and adding the improved logic in Control Panel. The current FLR logic in hypervisor has some issues: 1) Dstate transition is not guaranteed to properly clear the device state; 2) the current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND doesn''t mean the

This adds a boolean boot parameter to xen to allow reserved memory regions to be added to the iommu mappings for dom0. The parameter is "iommu_include_reserved" and is off by default. A warning is also traced when incorrect RMRR to system memory map values are detected. This is being added to address some incorrect BIOS''s that do not report correctly the requied reserved memory

...oost the performance of such guests including 32-bit Windows XP/2003. Moreover, with the patch, local APIC accesses other than TPR in guests are intercepted directly as APIC_ACCESS VM exits rather than PAGE_FAULT VM exits; this can lower the emulation cost of such accesses.

I have successfully passed through a video card, network card, USB mouse, and USB keyboard to a MS Vista guest. That works well. I am trying to add another PCI device, such as a audio card or PCI USB hub, but I am running into a strange problem. When I plug the PCI audio (or USB card) to the motherboard. It makes it so that the PCI video card is no longer an "assignable device" (xm

On Xen-3.3.0, domain0 Megaraid SAS (SAS 1068 controller) driver is not loading correctly if vtd support in Xen is enabled. It fails at the point of initializing firmware.
