Revision 1629, 6.3 kB (checked in by jwoithe, 15 years ago)

RME: refine shared device configuration locking. Rename some data objects for clarity. Move frequency settings into the shared configuration object since ultimately these need to be accessible to all FFADO/RME processes. Other minor cleanups.
