Hello!!! Our network driver support ioctl calls from applications for register reads/writes. I am wondering can ioctl calls be supported from domU to dom0? i.e call flow will be application invokes ioctl ---> netfront ioctl ----->via xenbus ------> netback ioctl ------> to actual driver in dom0 with the return path in similar fashion. Looked at the existing netfront and netback drivers and with my understanding it seems it is not possible. I looked at scsifront and scsiback, assuming storage drivers should be supporting ioctls, didn't see anything related to it. Wanted to know what's the mechanism to support ioctls. Inputs appreciated. Thanks -RK _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
