From bouyer via NetBSD. Note we are now sync'd with the latest (1.78 siop.c, 1.37 siop_common.c) NetBSD code. Tested by various people over the last year+. Didn't solve any of their problems but didn't cause any regression either. 2005-10-08T15:59:05Z krw krw@openbsd.org 2005-10-08T15:59:05Z urn:sha1:662cf6470572b510deed2e7ca6bb3da6eb428e95 2004-03-12T00:05:43Z miod miod@openbsd.org 2004-03-12T00:05:43Z urn:sha1:48cbe737bba1658da22519e0be3223ae3e4eaf3d 2003-07-01T17:15:06Z krw krw@openbsd.org 2003-07-01T17:15:06Z urn:sha1:21d58af63337217ebe078a16c378915bc1906941 mapped and sync'ed appropriately, and is guaranteed to be in one memory page. Eliminate now unused dmamap_cmd and rs_cmd fields. Fix another error message (adding active command to reset list) so that it includes the adapter name. Add missing letoh32() calls to debug code. The evils of directly mapping *xs->cmd were pointed out by Mickey during osiop development. In particular, *xs->cmd may start on one memory page and run into the next. Since the dma logic in most cards/drivers (including siop) only allocates one address/size pair to map *xs->cmd, parts of a command could be lost or corrupted. The large number of 6 byte dma mappings noted long ago by someone (Henric?). This change reduces the dma mapping activity per i/o by 1/3 to 1/2 and may give a performance boost of some kind. Successfully tested on i386, sparc64 (ultra30 - thanks Jolan, blade100), macppc and alpha. Unfortunately these changes don't fix the Blade1000 siop problems. **NOTE** If scsi_generic is ever upped to 16 bytes the offsets in siop.ss must be updated! 2002-09-16T00:53:12Z krw krw@openbsd.org 2002-09-16T00:53:12Z urn:sha1:7da44ad710f95893855a506343beb59abebcbca5 differences, undoing whitespace, spelling, etc. changes and adopting the NetBSD code instead of equivalent home grown code for PPR negotiation, etc. siop.c 1.21 -> 1.64 siop_common.c 1.12 -> 1.30 siopreg.h 1.7 -> 1.13 siopvar.h 1.13 -> 1.18 siopvar_common.h 1.10 -> 1.21 ncr53cxxx.c 1.5 -> 1.10 siop.ss 1.12 -> 1.17 siop_pci.c 1.8 -> 1.11 siop_pci_common.c 1.6 -> 1.17 siop_pci_common.h 1.2 -> 1.4 Many fixes, add 1010-66 support, restructure things to prepare for addition of esiop, osiop and oosiop drivers. tested on various archs by art@, millert@, wilfried@, jason@, Dan Weeks. ok deraadt@. 2001-04-15T06:01:28Z krw krw@openbsd.org 2001-04-15T06:01:28Z urn:sha1:ebc5123d9dad640cf018972880af9acb561fa129 Add support for PPR negotiations and DT transfers, and the preservation and restoration of the SCNTL4 register which controls Ultra3 transfers. Redo sync lookup, since the same period factor can mean two things depending on whether you are using DT or ST. Keep a minimum allowed ST period factor, and a minimum allowd DT period factor for each adapter. Currently NO support for QAS or IUS or AIP. 2001-02-15T04:07:57Z krw krw@openbsd.org 2001-02-15T04:07:57Z urn:sha1:26399a2e0359c5df47e32fd1a57443384904a22a Written for NetBSD by Manuel Bouyer. Tested with various cards on i386 and alpha. Outstanding issue: doesn't work with PowerPC yet.
