[Xen-users] (XEN) physdev.c:61: dom1: map invalid irq 1251
Hello,
i''m using the latest Xen 4.0 testing from the mercurial repository and
i want to passthrough my Intel Core gpu. But somehow it has a weird IRQ of 1251.
So i cant start the vm if i set pci=[''00:02.0'']. The device is
bound to the pciback driver correctly.
The interesting part of xm dmesg (appears when i start the vm):
(XEN) [VT-D]iommu.c:1484: d0:PCI: unmap bdf = 0:2.0
(XEN) [VT-D]iommu.c:1362: d1:PCI: map bdf = 0:2.0
(XEN) physdev.c:61: dom1: map invalid irq 1251
(XEN) [VT-D]io.c:300: d1: bind: m_gsi=55 g_gsi=36 device=5 intx=0

What does /proc/interrupts look like? Is the Dom0 64-bit or 32-bit? What does ''xm debug-keys <x>'' where x is M, i, Q, z tell you before and after you have tried to pass in the PCI device to the guest? Oh, and what does ''xm dmesg'' show?> > The interesting part of xm dmesg (appears when i start the vm): > > > > (XEN) [VT-D]iommu.c:1484: d0:PCI: unmap bdf = 0:2.0 > > (XEN) [VT-D]iommu.c:1362: d1:PCI: map bdf = 0:2.0 > > (XEN) physdev.c:61: dom1: map invalid irq 1251 > > (XEN) [VT-D]io.c:300: d1: bind: m_gsi=55 g_gsi=36 device=5 intx=0 > > (XEN) [VT-D]iommu.c:1484: d1:PCI: unmap bdf = 0:2.0 > > (XEN) [VT-D]iommu.c:1362: d0:PCI: map bdf = 0:2.0 > > > > > > lspci -vvv: > > > > 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12) (prog-if 00 [VGA controller]) > > Subsystem: Micro-Star International Co., Ltd.
