Re: [Xen-devel] question about the poll_timer

[tgh <tianguanhua@xxxxxxxxxx>]

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
