-pci passthrough doesn´t work
-
-Hi all,
-
-I have some problems passing through a pci device to kvm guest.
-First I have to say that I´m using the latest kvm-kernel und qemu-kvm from git-tree (Date 11.06.2011).
-
-I want´t to passthrough this device to guest:
-
-lspci-output:
-
-02:00.0 Multimedia video controller: Micronas Semiconductor Holding AG Device 0720 (rev 01)
-
-So at first I have bind the driver to psi-stub:
-
-modprobe -r kvm-intel
-modprobe -r kvm
-echo "18c3 0720" > /sys/bus/pci/drivers/pci-stub/new_id
-echo 0000:02:00.0  > /sys/bus/pci/devices/0000:02:00.0/driver/unbind
-echo 0000:02:00.0  > /sys/bus/pci/drivers/pci-stub/bind
-modprobe kvm
-modprobe kvm-intel
-
-Then I have assigned device to guest:
--device pci-assign,host=02:00.0
-
-When I start the guest. The device succesfully get´s an msi-IRQ on host-system:
-
-cat /proc/interrupt output:
-
- 32:          0          0          0          0   PCI-MSI-edge      kvm_assigned_msi_device
-
-
-On guest device is visibel:
-
-lspci output:
-00:04.0 Multimedia video controller: Micronas Semiconductor Holding AG Device 0720 (rev 01)
-
-
-Sometimes the device (on guest) get´s an IRQ between 10-16:

-
-
-Sometimes the device (on guest) gets an msi-irq f. e. IRQ 29.
-Then kernel-modul (ngene) can succesfully load the driver and all works fine.
-
-
-Short to say:
-
-HOST 	GUEST		STATUS
-MSI-IRQ	MSI-IRQ		ALL FINE
-MSI-IRQ IOAPIC-IRQ	DOESN´t WORK
-
-with modinfo I had a look at the kernel-modul if there is way to force msi, but without success.
-
-But I think IRQ between (10-16) should also work because when I load the kernel-modul on host with IRQ (10-16)
-it works. (Device only get´s an MSI-IRQ If I start the vm to passthrough)
-
-Do anyone know where can be the problem?
-
-Here is the dmesg - output of second device which is currently working on guest with MSI-IRQ 29:

-Triaging old bug tickets ... can you still reproduce this problem with the latest version of QEMU? Or can we close this ticket nowadays?

-[Expired for QEMU because there has been no activity for 60 days.]
