At the moment, most of the commands chain 3 descriptors: 1 - class + command 2 - command specific 3 - ack We could merge 1 and 2 into a single one, both are read only for the device, so I take it back, it won't need a bigger ring. But it will need 2 descriptors at least(1 read only for the device and 1 write only for the device), so we still need to fail probe sometimes. _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
