Attached is a patch for shared interrupt between dom0 and HVM domain for vtd. Most of problem is caused by that we should inject interrupt to both domains and the physical interrupt deassertion then may be delayed by the device assigned to the HVM. The patch adds a timer, and the time out value is sufficient large to tolerant the delaying used to wait for the physical interrupt deassertion.

There is a BUG_ON() at xen/arch/x86/physdev.c:169 which appears to be dependent upon guest behavior (should close event channel before un-mapping pirq), rather than on internal hypervisor state. In 2.6.18, this likely goes unnoticed because pci_device_shutdown() only calls all the driver shutdown routines. In newer kernels, however, it also calls pci_msi_shutdown() and pci_msix_shutdown(), which

Could a drm guru please have a look at kern/133554? Thanks, -cpghost. -- Cordula's Web. http://www.cordula.ws/

This patchset implements the KVM part of the synthetic interrupt controller (synic) which is a building block of the Hyper-V paravirtualized device bus (vmbus). Synic is a lapic extension, which is controlled via MSRs and maintains for each vCPU - 16 synthetic interrupt "lines" (SINT's); each can be configured to trigger a specific interrupt vector optionally with auto-EOI

Hi all, First thing first: It works, I now no longer have a few dropped frames every 10s on my testbox here with the pageflip i-g-t tests. Random notes: - New design has per-crtc locks to protect the crtc input-side (pageflip, cursor) for r/w and the output state of the crtc (mode, dpms) as read-only. It also required completely revamped fb lifecycle management, those are now refcounted

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.
