-Currently, there are two drivers:
-

-telecomparistech/
----
-- supports the new ExpressMIMO-1 bitstream by Telecom Paristech
-- uses command two command FIFOs to pass commands between Leon<->PC
-
-
-eurecom/
----
-- supports the legacy ExpressMIMO-1 bitstream
-- supports ExpressMIMO-2, also multiple cards for sample-synchronous acquisition
-- uses CONTROLx registers to pass commands between Leon<->PC
-- allocates buffers in kernel space using pci_alloc_consistent
-- used by ../USERSPACE/LIB/openair0_lib for simple access through userspace
