Re: [Xen-ia64-devel] [Q] about PCI front/IA64

[Atsushi SAKAI <sakaia@xxxxxxxxxxxxxx>]

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 pirq_find_routing_table@arch/i386/pci/irq-xen.c is  pci_sal_read/write for 
IA64.
(DomU/VTI cannot access PCI configuration)


Thanks
Atsushi SAKAI
