From c1b34d5a9269ccdd35c581bc158acbe5888fec06 Mon Sep 17 00:00:00 2001 From: Till Straumann Date: Wed, 31 Jan 2007 04:02:52 +0000 Subject: 2007-01-30 Till Straumann * vmeUniverse/README.porting, vmeUniverse/README.universe: updated, added more information for BSP implementors. * vmeUniverse/VMEDMA.h (added): VME DMA API definition. * vmeUniverse/bspVmeDmaList.h (added), vmeUniverse/bspVmeDmaListP.h (added), * vmeUniverse/bspVmeDmaList.c (added): Driver-independent code for linked-list DMA (public + private headers, implementation). * vmeUniverse/vmeUniverseDMA.h (added), vmeUniverse/vmeTsi148DMA.h (added): interface to new DMA features of drivers. * vmeUniverse/vme_amd_defs.h: Added definition for data-width hint bits (VME_MODE_DBWxx). * vmeUniverse/vmeTsi148.c: added DMA support. Added support for data-width hint/modifier bits. * vmeUniverse/vmeUniverse.c, vmeUniverse/vmeUniverse.h: Added support for data-width hint/modifier bits. Added support for xxx_BLT, xxx_MBLT address modifiers. Restrict DBW to 32 in non-MBLT modes (except single-beat; a comment is in README.universe). Updated DMA support to implement new VMEDMA.h API. Added support for non-incrementing VME addresses. Restrict data width to 32 for single-beat AMs when the universe would use MBLT for DMA. --- c/src/lib/libbsp/shared/vmeUniverse/vmeTsi148DMA.h | 88 ++++++++++++++++++++++ 1 file changed, 88 insertions(+) create mode 100644 c/src/lib/libbsp/shared/vmeUniverse/vmeTsi148DMA.h (limited to 'c/src/lib/libbsp/shared/vmeUniverse/vmeTsi148DMA.h') diff --git a/c/src/lib/libbsp/shared/vmeUniverse/vmeTsi148DMA.h b/c/src/lib/libbsp/shared/vmeUniverse/vmeTsi148DMA.h new file mode 100644 index 0000000000..11543a96bf --- /dev/null +++ b/c/src/lib/libbsp/shared/vmeUniverse/vmeTsi148DMA.h @@ -0,0 +1,88 @@ +/* $Id$ */ +#ifndef VME_TSI148_DMA_H +#define VME_TSI148_DMA_H + +#include + +/* + * Authorship + * ---------- + * This software was created by + * Till Straumann , 2006, 2007 + * Stanford Linear Accelerator Center, Stanford University. + * + * Acknowledgement of sponsorship + * ------------------------------ + * This software was produced by + * the Stanford Linear Accelerator Center, Stanford University, + * under Contract DE-AC03-76SFO0515 with the Department of Energy. + * + * Government disclaimer of liability + * ---------------------------------- + * Neither the United States nor the United States Department of Energy, + * nor any of their employees, makes any warranty, express or implied, or + * assumes any legal liability or responsibility for the accuracy, + * completeness, or usefulness of any data, apparatus, product, or process + * disclosed, or represents that its use would not infringe privately owned + * rights. + * + * Stanford disclaimer of liability + * -------------------------------- + * Stanford University makes no representations or warranties, express or + * implied, nor assumes any liability for the use of this software. + * + * Stanford disclaimer of copyright + * -------------------------------- + * Stanford University, owner of the copyright, hereby disclaims its + * copyright and all other rights in this software.
