Accelerated msix entry is initialized to zero when msixtbl_pt_register is called. This doesn''t match the value from qemu side, although pirq may already be mapped and binded in qemu side. Kernel will get wrong value when reading msix info. Signed-off-by: Zhenzhong Duan <zhenzhong.duan@oracle.com> Tested-by: Yuval Shaia <yuval.shaia@oracle.com> --- tools/libxc/xc_domain.c

Hi all, The series is a draft of generic MSI driver that supports PCI and Non-PCI device which have MSI capability. If you're not interested it, sorry for the noise. The series is based on Linux-3.16-rc1. MSI was introduced in PCI Spec 2.2. Currently, kernel MSI driver codes are bonding with PCI device. Because MSI has a lot advantages in design. More and more non-PCI devices want to use

Hi- I am trying to pass an LSI SAS2008-based HBA (IBM M1015) through to an HVM Solaris VM, using Xen 4.2 unstable and the qemu-traditional device model. On boot I see the following error: MPT BIOS Fault 09h encountered at adapter PCI(00h,05h,00h) A list search yielded (http://comments.gmane.org/gmane.comp.emulators.xen.devel/128172), however there was no solution for an HVM VM.
