Re: [Xen-ia64-devel] [Q] about PCI front/IA64
Hi, Tristan Thank you for your comments. I am wondering the code of arch/i386/pci/pcifront.c and irq-xen.c for x86. (IA64 does not have it) The [EMAIL PROTECTED]/i386/pci/irq-xen.c is pci_sal_read/write for IA64. (DomU/VTI cannot access PCI configuration) Thanks Atsushi SAKAI Le Vendredi 13 Octobre 2006 13:52, Atsushi SAKAI a ecrit : I'm just watching through the source code of PCI front/back driver. But I did not understand the interface of Para/IA64 kernel. (x86 has driver at linux-sparce/arch/x86/driver/pci but IA64 does not have such.) If anyone know the interface, please let me know thanks. pcifront implements a 'driver' to manage a pci bus. pciback is a PCI driver, almost like any standard PCI driver. I do not really understand your question. Please, be more specific. Tristan. ___ Xen-ia64-devel mailing list Xen-ia64-devel@lists.xensource.com http://lists.xensource.com/xen-ia64-devel

(DomU/VTI cannot access PCI configuration) HI, I am not 100% sure, but I think the routing table is extracted from ACPI tables. DomU doesn't really need this because it uses event channel. domVTI should use pci_sal_read/write which is emulated by qemu.
