Thank you for your reply
I read to the function do_pci_op() you told me,but I am not familiar with the pci facility I guess the poll_timer gives a interval for pci probing before time out or something
could you tell me more about pci and poll_timer

Thank you in advance

Hi,

Have you ever seen the do_pci_op() of
linux-2.6-sparse/drivers/xen/pcifront/pci_op.c?

Thanks
