Author: scottl Date: Fri Feb 20 06:10:12 2009 New Revision: 188840 URL: http://svn.freebsd.org/changeset/base/188840 Log: Add basic support for DDF, often found on Adaptec HostRAID controllers. Spares and rebuilds are not supported, so this code should be considered for entertainment purposes only. Added: head/sys/dev/ata/ata-raid-ddf.h (contents, props changed) Modified: head/sys/dev/ata/ata-raid.c head/sys/dev/ata/ata-raid.h Added: head/sys/dev/ata/ata-raid-ddf.h ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/sys/dev/ata/ata-raid-ddf.h Fri Feb 20 06:10:12 2009 (r188840) @@ -0,0 +1,333 @@ +/*- + * Copyright (c) 2008 Scott Long + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
