vbareg.h(9s)
NAME
  vbareg.h - VMEbus: Contains definitions for VMEbus support

DESCRIPTION
  The <vbareg.h> file defines bit constants that the dma_map_alloc(),
  dma_map_load(), vba_map_csr(), vba_set_dma_addr(), busphys_to_iohandle(),
  vba_badaddr(), and vba_get_info() kernel routines use.  The file also
  defines bit constants that device drivers use for the addr1_atype  and
  addr2_atype members of the driver data structure.

WHEN TO INCLUDE
  VMEbus block and character device drivers include this file in order to use
  the VMEbus bit constants.

OF SPECIAL INTEREST
  Items of interest to device driver writers are the bit constants that the
  flags argument of dma_map_alloc(), dma_map_load(), vba_map_csr(),
  vba_set_dma_addr(), busphys_to_iohandle(), and vba_badaddr() use.
