This is the GE Intelligent Platforms, Inc. RFM2g Reflective
Memory Device Driver for Linux:
(3.x kernel. Ubuntu 14.04 64bit, Fedora 20 64bit)
(2.4 kernel, Red Hat(tm) 7.2, 7.3, 8.0, and 9.0)
(2.6 kernel, Red Hat(tm) Enterprise Linux 5)

(2.4 kernel, Red Haggis Linux LSP-7436 for PPC platforms)
The following feature set is implemented in this release:
o Open
o Close
o Read a buffer from reflective memory
o Write a buffer to reflective memory
o Peek a byte, word, or longword from reflective memory
o Poke a byte, word, or longword to reflective memory
o Read or write using the RFM2g board's DMA engine
o Send an interrupt event to another RFM2g node
o Get or set the status of the RFM2g board's Status LED
o Get or set the driver's debug flag settings
o Synchronous event notification, which allows the user to block
(with timeout) on the arrival of an interrupt event
o Asynchronous event notification, which allows a user-specified

See rfm2g/include/rfm2g_api.h for the API function prototypes.
To use the RFM2g driver with your application, you must include rfm2g_api.h,
and link to the RFM2g API and POSIX Threads libraries. For examples,
change to the rfm2g/samples directory and examine the files Makefile_s,
Makefile_r, Makefile_m, rfm2g_sender.c, rfm2g_receiver.c, and rfm2g_map.c.
See install.txt on the distribution media for installation instructions.
