Hello, I am desperately trying to get pci-passthrough to working. I want to pass a tg3 nic to domU. when booting domU I get a lot of messages: pcifront pci-0: pciback not responding!!! in domU, "ifconfig eth... adress up" hangs for 2 minutes, finally ifconfig -a shows a correct setting with no data transmitted rx/tx The IP Adress is being assigned, but there is no data transmission possible on this interface (ping ..) lspci in domU als...

Hello, The topic is self-explanatory: how to ensure that a PV driver domain correctly prepares its PCI devices for S3 sleep? If I do "pm-suspend" in dom0, and the driver domain has active network interfaces, suspend hangs the system. Yes, in case of this particular machine, suspend works fine when there is no driver domain. It is possible to manually invoke scripts from

Use new PCI interfaces to simplify xen-pcifront implementation: 1) Use pci_create_root_bus() instead of pci_scan_bus_parented() because pci_scan_bus_parented() is marked as __deprecated.This also gets rid of a duplicated call of pci_bus_start_devices(). 2) Use pci_stop_root_bus() and pci_remove_root_bus() instead of open-coded private i...

When destroying pcifront/pciback, the following message appears in the guest linux kernel log. WARNING: g.e. still in use! WARNING: leaking g.e. and page still in use! This is caused by the wrong disconnect procedure that pcifront terminates the gnttab foreign access before pciback unmaps the ring. This patch correc...

...plit device drivers for PCI. (pci front and PCIback). Which are normally communicating over xenbus. which looks almost like other split drivers. How exactly then passthrough enables use of domU''s drivers ? 3. And if passthrough support isnt provided how will communication between pcifront-pciback be different ? ( I guess netbsd , freebsd do not have passthrough support yet ) 4. What restricts other domUs from accessing PCI device given to other domU via passrthrough support.

...ommand line, I am able to hide a port of the fiber channel HBA card from Dom 0. Now, I have a RHEL 4 Update 5 x86 running as a para-virtualized guest. The Dom U kernel is kernel-xenU-2.6.9-55.el4. I intend to allow the PV guest to have direct access to a port on the HBA card. However, there are no PCIFRONT and LPFC kernel modules in the xenU kernel. Only BLKFRONT and NETFRONT are supported by default. LPFC is a kernel module for the Emulex HBA card. To compile these two kernel modules, I downloaded and installed kernel-2.6.9-55.el5.src.rpm, which is the full kernel sources (with xen patches) for RHEL...

Hi, It seems that destroying pcifront/pciback always fails on current xen. This patch fixes the problem, making pciback switch to "Closed" state after pcifront switched to "Closing" state.
