* $Log: gdth.c,v $
+ * Revision 1.73 2004/03/31 13:33:03 achim
+ * Special command 0xfd implemented to detect 64-bit DMA support
+ *
+ * Revision 1.72 2004/03/17 08:56:04 achim
+ * 64-bit DMA only enabled if FW >= x.43
+ *
+ * Revision 1.71 2004/03/05 15:51:29 achim
+ * Screen service: separate message buffer, bugfixes
+ *
+ * Revision 1.70 2004/02/27 12:19:07 achim
+ * Bugfix: Reset bit in config (0xfe) call removed
+ *
+ * Revision 1.69 2004/02/20 09:50:24 achim
+ * Compatibility changes for kernels < 2.4.20
+ * Bugfix screen service command size
+ * pci_set_dma_mask() error handling added
+ *
+ * Revision 1.68 2004/02/19 15:46:54 achim
+ * 64-bit DMA bugfixes
+ * Drive size bugfix for drives > 1TB
+ *
+ * Revision 1.67 2004/01/14 13:11:57 achim
+ * Tool access over /proc no longer supported
+ * Bugfixes IOCTLs
+ *
+ * Revision 1.66 2003/12/19 15:04:06 achim
+ * Bugfixes support for drives > 2TB
+ *
+ * Revision 1.65 2003/12/15 11:21:56 achim
+ * 64-bit DMA support added
+ * Support for drives > 2 TB implemented
+ * Kernels 2.2.x, 2.4.x, 2.6.x supported
+ *
* Revision 1.64 2003/09/17 08:30:26 achim
* EISA/ISA controller scan disabled
* Command line switch probe_eisa_isa added
* shared_access:N enable driver reserve/release protocol
* probe_eisa_isa:Y scan for EISA/ISA controllers
* probe_eisa_isa:N do not scan for EISA/ISA controllers
+ * force_dma32:Y use only 32 bit DMA mode
+ * force_dma32:N use 64 bit DMA mode, if supported
*
* The default values are: "gdth=disable:N,reserve_mode:1,reverse_scan:N,
* max_ids:127,rescan:N,virt_ctr:N,hdr_channel:0,
- * shared_access:Y,probe_eisa_isa:N".
+ * shared_access:Y,probe_eisa_isa:N,force_dma32:N".
* Here is another example: "gdth=reserve_list:0,1,2,0,0,1,3,0,rescan:Y".
*
* When loading the gdth driver as a module, the same options are available.
*
* Default: "modprobe gdth disable=0 reserve_mode=1 reverse_scan=0
* max_ids=127 rescan=0 virt_ctr=0 hdr_channel=0 shared_access=0
- * probe_eisa_isa=0"
+ * probe_eisa_isa=0 force_dma32=0"
* The other example: "modprobe gdth reserve_list=0,1,2,0,0,1,3,0 rescan=1".
