We have similar issues with spurious dma transfers and interrupts on all device classes. The ->remove callback must make sure the device is in a quiscent state, by whatever means are nessecary. This is absolutely nessecary for hot removals to work. > That is > why the Quadrics extensions for zero placement are not > applicable to an RDMA device.

How is memory remapping related to device removal? _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
